Where Did The Revit 2021 Fabrication Extension Addin Go?

Have you tried to Import or Export an MAJ file in Revit 2021? Have you tried to run a Fabrication Report or Export in Revit 2021? If so, you may have noticed that it’s not in the Add-Ins ribbon any longer.

Your first thought might be you need to install the Revit Extension for MEP Fabrication 2021. But even after installing, it’s still not there. You might then be tempted to submit a support ticket to Autodesk to help troubleshoot your install. No need. Autodesk simply moved the commands and made them more integrated to Revit.

MAJ Exports

MAJ Exports can now be found in two locations in Revit 2021. The first location is under File -> Export.

The second location shows up in the context ribbon when you select Fabrication Parts….

MAJ Import

MAJ Imports have moved as well. This is a little easier to find if you think about it, it’s located under the Insert ribbon.

Fabrication Reports / Fabrication Exports

Your Fabrication Reports and Fabrication Exports will also show up in the context ribbon when you select Fabrication Parts.

Context Ribbon Doesn’t Show MAJ Export or Fabrication Reports/Exports?

If you select parts in Revit and the context ribbon does not show the MAJ Export or Fabrication Reports/Exports drop-downs, take a look at the Ribbon’s title.

If the Title of the ribbon says Multi-Select, this means you have a more than just MEP Fabrication Parts selected. You can quickly filter your selection to just MEP Fabrication Parts using the Filter tool in the lower right of Revit.

Un-check all items except anything that begins with “MEP Fabrication …”. This will deselect any non-Fabrication Parts and your MAJ Export and Fabrication Reports/Exports tools will then show up.

Still Can’t Find These Tools?

Unlike prior years which required a separate install, Revit 2021 installs the Fabrication tools as part of the product install. However, if the tools somehow become uninstalled, and you don’t find them, you can reinstall them by downloading the Revit Extension for MEP Fabrication 2021 from your Autodesk Account. Alternatively, you should be able find it in the Autodesk Desktop App in the updates.

Fix – Revit Fabrication Parts Suddenly Become Invalid

If you’re using Revit 2018 or 2019 with Fabrication Parts, you may notice that upon loading or reloading your configuration some (or many) of your parts become “Invalid”.

I’m not talking about Fabrication Parts who’s CID/Pattern isn’t supported in Revit. I’m referring to perfectly valid Fabrication Parts. Parts that once worked. They may even be currently in your model but are no longer active in your Parts Browser. Here’s a couple examples…

You may even notice valid parts become invalid after unloading a service or that invalid parts become valid again after loading a new service.

What’s happening is that your Fabrication Configuration’s Image Cache has become corrupt. The issue is in Revit 2018 and 2019. Revit 2020 does not experience the issue. Whatever changed in Revit 2020 made it more resilient to a corrupt image cache.

The only known fix until recently was editing your service template. You would have to remove and re-add the part. Reloading the Fabrication Configuration in Revit and it would be fixed. Unfortunately, future database changes would often revert back to the invalid state.

Quick and Dirty Work-Around (Revit 2019 Only)

If you’re using Revit 2019, there is a quick and easy work-around. That’s assuming you only have a few parts that are invalid. To work around the issue, reload your Fabrication Configuration and individually load the invalid part in the Parts tab. The following image shows one invalid part added to the Parts tab.

Once added, the Part then becomes valid in the Parts Browser.

A Permanent Fix (For both Revit 2018 & 2019)

The prior work-around was only available in Revit 2019. This didn’t help Revit 2018 projects which do not have the Parts tab in Fabrication Settings.

To properly fix the issue, you need CADmep. Load your Fabrication Configuration in CADmep. Once loaded, find an open area of your service and press CTRL+SHIFT+Right-Click and select Clear Cache.

Next type the REFRESHALLBTNS command. You’ll see a progress bar while CADmep refreshes your button image cache.

At this point, your button cache should be rebuilt. However I’ve seen instances where you have to “coerce” or otherwise persuade CADmep into saving it back to disk. To verify the changes are saved, go to the Service Editor and click the Apply button then close the dialog.

At this point, you should be all set. If you go back to the problem Revit file and reload your Fabrication Configuration, you should see the Fabrication Part become active again.

Preventing Future Corruption

To prevent future corruption, you first need to understand how it happens. When loading CADmep, you may have noticed the “Button Validation” as shown in the following image…

Because this can be a slow process, most users simply hit the Escape key to terminate the validation. This isn’t a big deal for a user. For a database administrator, this can leave your image cache partially built and corrupt it.

While you can simply stop canceling the process, the better option is to prevent it in the first place. By default, CADmep enables Button Validation. But you can turn it off. To do this, use the Edit Configuration utility that comes with CADmep.

Note that this utility is named the same between versions and between CADmep, ESTmep and CAMduct products. It may be tricky to pick the right one. You need to select the one that comes with CADmep.

You also need to perform this for each CADmep version that’s installed. To help, you may want to choose the Open file location option. This will bring you to the folder with the shortcuts. You can then easily navigate to the proper version of Edit Configuration that you’re looking for.

When you run the utility, it’ll prompt for a configuration. You can pick any, it doesn’t matter. The setting to change is not specific to the configuration, only the product and version for the currently logged in user. The following image shows the Skip Validate Buttons at Start-Up option.

Select this option and the next time you launch CADmep, you’ll no longer see the button validation. This prevents you from canceling out of the validation as well as speeds loading of CADmep.

Credit Goes To…

Special thanks to Martin Schmid and Craig Farish of Autodesk for helping with this issue. We’d been experiencing this issue on and off for over 1/2 a year. Autodesk Support had indicated that nobody else had reported the issue and provided the 2019 work-around. They repeatedly assured me it was fixed in 2020 and not a problem with my data. They had no fix for 2018 which is used by several projects.

After experienced a large volume of invalid buttons, our database administrator spent 6 hours before users arrived rebuilding service templates. The the issue resurfaced within hours of a simple database update. With $5k-10k of lost productivity over 2 weeks with several detailers unable to model certain services, I called in a favor with Martin and Craig. They quickly had their team analyse our data and identify the fix.

I’ve since run into 4 other companies experiencing the same issue and this fix has worked flawlessly for them as well. Hopefully you’ll not need it but if you do, it’ll save you load of time, frustration and money.

Revit Can’t See Fabrication Configuration

Every once and a while, a Fabrication Configuration can lose data or become corrupt which leaves Revit unable to access it. This after you’ve already been working in a model and using the configuration without issue.

When this happens, it’s likely a result of the Fabrication Configuration loosing it’s GUID or “Global Unique Identifier”. You really only notice when attempting to reload the configuration in one of your existing models. The error will look like the following image…

When you launch of the other Fabrication products (CADmep, ESTmep or CAMduct) you can view the data from the database editor. In the image below, you can see the data is missing.

Retrieving Lost Data

The good news is that you can the data back. For this, we’ll use Revit and Dynamo, Revit’s visual programming environment.

Start Revit and open up one of your existing project that already had a Fabrication Configuration loaded. From the Manage ribbon, click the Dynamo button.

Once in Dynamo, you’ll need to load a Fabrication Dynamo package. Click the Package menu to display the Online Package Search dialog. You’ll need to wait a little while for the dialog to populate. Once populated, you can type Fabrication in the search box. In the results, select the DynaFabrication2018 package. Next, click the down arrow button on the left to install it as shown in the following image…

Once installed, the dialog will show the loaded modules at the bottom. It should look like the following image…

After the Dynamo packages are installed, you can build a Dynamo program that will extract the needed data. But instead of walking you through that, simply download, unzip and open the Dynamo program I’ve already created.

One Dynamo program Get Missing Fabrication GUID.dyn is loaded, your Dynamo screen should look like the following image…

In the lower right corner, if the button says Manual click the Run button otherwise if it’s set to Automatic, the information you need is already populated. Record the data in the fields marked A, B & C. This is what you’ll enter back in the database.

Add Data Back to the Fabrication Configuration

Launch of one the Fabrication products (CADmep, ESTmep or CAMduct). In the database editor, enter the information from Dynamo into the fields marked A, B & C as shown below…

Exit the database editor and exit from the Fabrication product you launched. If you still have Revit/Dynamo loaded, close both. Now, relaunch Revit again and open the model you opened before.

When you go to reload the configuration again, Revit should successfully find and reload your configuration.

Revit Fabrication Parts – Control w/Dimensions

AutoCAD was famous for it’s command line. It was easy to move items and type locations, distances or coordinates. Revit isn’t quite as intuitive for those coming from AutoCAD.

There’s a lot of reasons you need more control of Fabrication Parts in Revit. You may want to align the ends of pipe for a rack. Or perhaps you want to control the spacing between pipes in a run of parallel pipes.

At first it appears like the best you can do is drag items close. Eyeball them up so to speak. The traditional methods used in AutoCAD just won’t work. Methods like drawing construction geometry and using point filter and/or object snaps.

You can precisely control placement and location when moving to Revit from CADmep. In Revit, you simply place dimensions and edit them. Seems easy enough but there’s a couple nuances that can leave users frustrated. We’ll cover how to do this below.

Adding Dimensions in Revit

You can use the Annotate tab on the Ribbon in Revit. You’ll use the Linear, Aligned and Angular dimensions the most.

When you place a dimension between parts in Revit, the obvious thing would be to double-click the dimension to edit it. You’ve likely seen the following dialog…

If you see this dialog, you’re on the wrong path. This is not where you’d edit a dimension to control part placement. For controlling parts with dimensions in Revit, you actually select one of the parts you dimensioned.

The following image shows a Fabrication Part selected. But there’s still a problem. If the dimension text is black, you can not edit it. This is because one of the parts are over constrained. If you find a Lock icon on one of the parts, try unlocking it.

After unlocking the part, you may need to deselect and re-select the part for the dimension text to be editable. In the following image, you’ll see the dimension text is now Blue.

With the dimension text Blue, you can now click on the text to edit it as shown in the following image.

With the edit box for the dimension text activated, simply type the desired value and press <Enter> or click out of the edit box.

You’ll see the part move to the dimension you entered. The key to determining which part moves when editing a dimension is based on the part you select. If you just wanted to align the parts, you can delete the dimension afterward. On the other hand, if you want to maintain that relationship, highlight the dimension. You’ll see a unlocked Lock icon as shown in the below image.

If you click to Lock the icon, this relationship between parts will be maintained going forward.

The below video shows three pipes modeled with various end lengths. We’re using dimensions to align the ends of the pipe. We also delete the dimensions afterward. Moving one of the pipe ends later will not move the ends of the other.

Pipe spacing is set using dimensions just like before only this time, the dimensions are retained and the lock icon locked When one pipe later moves, the other moves to maintain the spacing.

Disabled Material & Specification in Revit Fabrication Parts

Fabrication Parts in Revit don’t always allow editing of their Material or Specification properties. Look at the below side by side images. Revit’s properties can be seen grayed out on the left but those on the right are not.

Material & Specification Properties – Left Read Only, Right = Read/Write

Revit can obscure the reason for this because you have no access to edit your Fabrication Database within the Revit environment. The answer however is quite simple.

Fabrication Parts with the “BoughtOut” property set do not allow editing of Material or Specification. After all, a bought item is typically static and can’t be easily changed. Non-BoughtOut items do allow editing of the Material and Specification properties.

The following is another side by side image of Fabrication Part properties. The properties on the left have the BoughtOut property set. The properties on the right do not have the BoughtOut flag set. While not accessible from Revit, any of the other Autodesk Fabrication products can display and edit the BoughtOut property.

BoughtOut Property / Left = Set, Right = Not Set

ATTN: Autodesk Fabrication Part Users – Revit 2019.2.1 Hotfix

For Autodesk Fabrication Part users, this is a Hotfix you’ll want to get applied. Since the first release of Fabrication Parts in 2016, there’s been ongoing issues with MEP Systems modeled with Fabrication Parts.

The issues is that to add/remove or update Fabrication services, you need to reload your configuration. This often would cause “disconnects” between parts. Often this would happen for no good reason or explanation as the parts involved may not have even had changes to them.

This has been a difficult issue for Autodesk to resolve because it’s been difficult to reproduce. Since the 2016 until now, Autodesk has slowly made the issue better but it’s still not eliminated. With this hotfix in 2019, Autodesk is taking another stab at it and hopefully it’ll be eliminate. IF not fixed once an for all, hopefully it’ll be another small incremental step better.

You can review the release notes for all Revit 2019 updates here. Look for the notes under 2019.2.1 Hotfix and you’ll see the following note…

“Resolved an issue that could cause MEP Fabrication elements to disconnect when reloading a Fabrication configuration.”

Downloading The Update

The Update is available from the Autodesk Desktop App provided it’s working for you. (Note: Mine seems to lockup or crash repeatedly since installing the Autodesk Desktop Connector. Uninstalling and reinstalling the Desktop App seems to only resolve the issues for a short while)

Alternatively you can download from the Autodesk Accounts portal if you have download permissions given to you from your contract administrator.

Revit Fabrication Parts – Pattern Support Analysis

It no secret that not every Autodesk Fabrication pattern is supported in Revit. I’ve recently finished a more in-depth analysis of which patterns are and are not supported in Revit. Each of the 703 different pattern types were tested in each version and each update of Revit.

On the Fabrication COD Scripts page, you can find a Revit Support Report script. That script will analyse your ITM library and generate a CSV report of the status of every ITM in your Fabrication Configuration.

You can also find the complete results of my testing on the Revit Support page. Here’s a summary of the the testing…


Tested Version

Each of the below versions of Revit were tested with all the the 704 different patterns:

20162016R22061R2SP7
2017.02017.12017.2
2018.02018.12018.22018.3
2019.02019.12019.2

Testing Criteria

“Supported” for purposes of this testing is based on whether Revit allows a particular pattern to be used in the Fabrication Part Browser.


Testing Results

Testing results will have one of the following status descriptions.

  • No – No Revit support
  • Varies ({verison}) – Revit support varies between Revit version
  • Yes (Risk) – Revit does support but use NOT recommended due to issues
  • New ({version}) – New Pattern supported in later Revit versions
  • Yes – Pattern is supported in all Revit versions with no significant issues

Support Status = No

No – Parts not supported by the Parts Browser are obviously listed as having “No” support. There are a total of 84 different patterns listed in this category. They are as follows…

125126127

2200287331083873

Support Status = Varies

Varies (version) – In some cases, Fabrication Parts were initially allowed or supported in earlier versions and later were restricted. These parts have a status of “Varies” followed by the version where the change occurred. It’s recommended you avoid use of these patterns even in versions where they work as they will not be supported in later versions. There are 17 patterns that once worked in Revit but are no longer supported. They are as follows…

0182222381845853855864876898
903912915971110511701175

Support Status = Yes (Risk)

Yes (Risk) – Patterns that list “Yes (Risk)” are technically supported in Revit but I highly recommend avoiding their use. Patterns with this status have issues like inserting at the Revit’s Project Base Point and not the cursor location. They also have a tendency to crash Revit if you attempt to grip or edit them. As a result, I highly recommend avoiding their use. There are 29 patterns in this category. They are listed here…

922930962963968973115911601176

Support Status = New

New (version) – Some patterns were not around in earlier versions of Revit but later added and supported in Revit. These patterns are listed as “New” followed by the version of Revit they became available in. These patterns are generally safe to use for Revit. There are 19 patterns in this category which are listed here…

124512461247124812491250219721982217

Support Status = Yes

Yes – Parts allowed by the browser that work across all versions of Revit are listed with e “Yes” status. There are 555 patterns in this category. They are listed here…

Updated Revit Roadmap

Interested in what’s planned for future versions of Revit? Autodesk updated the Revit “Public Roadmap” in January of this year.

Follow this link to look what’s planned.

http://blogs.autodesk.com/revit/2019/01/23/revit-public-roadmap-january-2019/

Note: If you’re in the Mechanical Contracting business like myself, don’t hold your breath. Not much has changed in the last year. With all the talk from Autodesk about industrialized construction, we still see very little. Most of the contractors I know are starving for better tools and efficiency. We’re employing extra man hours and people continuing to develop “workarounds” for Autodesk’s lack of investment in our industry.

Beware! – Revit & Desktop Connector

If you use BIM360 Design (formerly “Collaboration for Revit” a.k.a. C4R) along with the Autodesk Desktop Connector, you should be aware of a common mistake that can lead to data loss.

BIM360 Design or C4R as the older version is called, is used to store Revit models in the cloud on Autodesk’s BIM360 platform. BIM360 Design using the BIM360 Docs platform as storage platform. C4R on the other hand uses the older BIM360 Team for storage of the Revit models.

While you could (can) upload your Revit models via the web interface to either storage platform, Revit would not see these files. They needed to be enabled for Collaboration and uploaded through Revit. This process made changes to the Revit files which enabled collaboration from BIM360 Design/C4R.

BIM360 Design/C4R collaboration is enabled and files uploaded using the Collaborate ribbon in Revit.

while Revit models need to be uploaded this way, there was no other way to upload other files types besides the web interface. Even if you did upload AutoCAD, IFC, Navis or other files types that Revit can link, there was no way to link these files into Revit from the BIM360 platforms. If you linked them from your server, the other members of your team without access to your server would not have access.

Autodesk Desktop Connector was created for this purpose. While you can’t link a non Revit file type into Revit directly from BIM360, you can use the Autodesk Desktop Connector to sync those other files types locally to your computer. Any other team members also using the Autodesk Desktop Connector would then also have access to those same files and the links would be identical.

What’s the problem?

The common problem that comes up when using BIM360 Design/C4R along with the desktop connector is Autodesk’s unfortunate choice in using the same icon for both products.

Depending where you see the icon, you get different results. If you click the one that references BIM360 collaboration services you’re good. If you click the one that references the Autodesk Desktop Connector, bad things can happen.

When a file is enabled for Collaboration and you open it through the Autodesk Desktop Connector, Collaboration is disabled and the file is configured as a local file or central file like you’d typically use of a file server. When this happens, the file is seen as being different and will not sync back to the BIM360 platform.

What this means then if that you have two different version of the file. One stored locally from the Autodesk Desktop Connector and another cached locally when opened from BIM360 Collaboration service (BIM360 Design / C4R) When you look at BIM360 Docs or BIM360 Team portals, you only see one version.

How do I know I’m using the correct Icon to open my Revit file?

Depending on the particular versions of Revit and their update versions, your install of Revit may appear different but the underlying concepts are the same. For these images, Revit 2018.3.2 and 2019.1 were used.

When opening a Revit model from 2018, you’ll see the “B” shortcut in the left. This is the proper way to open BIM360 Design/C4R enabled files. BIM360 Design and/or C4R sites will be listed depending if you have been given access to projects within those sites that use 2018 version of Revit.

Revit 2018 Open Dialog when accessing BIM360 Collaboration models.

When opening a Revit model from 2019, you’ll also see the “B” shortcut in the left. The same as with 2018 versions, this is the proper way to open BIM360 Design enabled files. BIM360 Design only will be listed because 2019 doesn’t use BIM360 Team/C4R. If nothing is displayed here, you may not have been given access to projects within those sites that use the 2019 version of Revit.

Revit 2018 Open Dialog when accessing BIM360 Collaboration models.

The other place you may see the BIM360 icon is from My Computer or other shortcuts that look at your local system. The following image shows 2018 when using the incorrect shortcut because it instead points to the Autodesk Desktop Connector drive on your computer.

And once again, 2019 versions of Revit are similar. On clue is that here, even though 2019 doesn’t support C4R, they are listed here. This is because you’re not accessing via Revit’s collaboration tools, you’re simply accessing a special local drive on your computer that’s syncing everything in the BIM360 platform completely independent of Revit.

More clues when opening Models from the Recent Files List

If you’re trying to open Revit models using the Recent Files list, there’s a few subtle clues that tell you if you’re opening a collaboration enabled BIM360 model or simply opening a model from the Autodesk Desktop Connector drive.

The following image shows Revit 2018 with a BIM360 Design/C4R model correctly. Notice the drive letter in the path as well as the “Cloud” image in the thumbnail.

The following image shows Revit 2018 with a Recent File that was accessed incorrectly from the Autodesk Desktop Connector. Notice the path will point to your Users folder on your computer and there’s no “Cloud” image on the thumbnail.

Similar to 2018 but formatted differently, Revit 2019 displays the same details in it’s Recent Files. The following image is 2019 showing a recent file opened correctly through BIM360 Collaboration tools.

Additional Clues

Looking at some of those subtle options can easily be overlooked or forgotten. Especially in the daily stress of production and deadlines. There are a few more obvious clues that can tell you if you’re opening your Revit models correctly.

For starters, when you open a BIM360 Design or C4R model properly in Revit, you’ll see a nice status dialog indicating that the files is being opened and sync’d locally.

On the other hand, there’s a major red flag when you open the files incorrectly though the Autodesk Desktop Connector. When you open the files incorrectly, you’re prompted to work on the model temporarily or save it locally as a Central Model. If you see this dialog, you know you opened the file incorrectly and should click the Cancel button.

If for some reason you or another user did open the file incorrectly, you can use the Autodesk Desktop Connector icon in the Windows System tray to review the pending actions. There will likely be warnings when reviewing the connector’s syncing status tasks. Note however that that lack of pending tasks with errors does not mean a file can’t been opened incorrectly. Any number of other actions could have overwritten the local copy or cleared those actions.

Another subtle clue is that if you look at the collaboration hubs and you see multiple projects that use different versions of Revit between them, you know you’re opening the models incorrectly. The Autodesk Desktop Connector display all projects, regardless of Revit version being used because it;s independent of Revit. When opening files correctly for BIM360 collaboration, Revit 2018 will only see 2018 project versions and Revit 2019 will only see 2019 project versions.

Again, if you don’t see differently projects that use different Revit versions, that does not mean you’re opening them properly. You merely may have been granted to projects of only one Revit version. But if you do see multiple projects you know are using different versions of Revit, it;s a sure sign you’re opening the files wrong.

Best To Avoid Using The Dropdown

The last word of warning is with using the drop down list in the Open dialog. Depending when and how you’ve accessed Models, neither BIM360 icon may be present, one or the other may be present, or both BIM360 icons may be present. Because they have no description, its hard to tell wich does which.

The following image shows the Dropdown list expended with both BIM360 icons displayed. One will take you to the proper BIM360 collaboration tools and the other, incorrectly to the Autodesk Desktop Connector.

Because of this very subtle difference, it’s likely a best practice to not use them ever. If they don’t show up on your system, don’t worry. They typically won’t display until you’ve first accessed the corresponding My Computer or BIM360 shortcuts on the left side of the dialog.
