Fabrication References – 2024 Update

Fabrication 2024 is out. I’ve updated all the reference information to include 2024 formats. As has been the trend the last few years, little has changed. Summary below…

Takeoff One of Every Size in Product List

I’m occasionally asked how one would add one of every size in a product list to their job. This very easy using ESTmep or CAMduct. CADmep however does not have this capability.

Here are the steps….


Step 1:
Start ESTmep / CAMduct with a blank job.


Step 2:
Go to Item Folders and navigate to the folder with the ITM(s) you wish to takeoff all sizes for. Select all the ITM’s and press CTRL+SHIFT+Right-Click and select Takeoff All Product Sizes.


Step 3:
Go back to the Items tab and review all the sizes of each item you selected.


Why Would You Do This?

There’s several reasons this may be helpful to you.

  • Any Size with dimensional errors is quickly found
  • A simple report shows you where you may have holes in your data (Price, Labor, Product Info, etc.)
  • Produce a quick MAJ that can be opened in CADmep (OpenJob) to measure each size to ensure dimensional accuracy.

If the option is grayed out/disabled, you’re one or more of the ITM’s in your selection is NOT Product Listed. For this to work, all items you’ve selected must be Product Listed.

Fabrication References – 2023 Update

Fabrication 2023 is out. I’ve updated all the reference information to include 2023 formats. As has been the trend the last few years, little has changed. Summary below…

Fabrication Reports – All One Folder

Those of you who used CADmep, CAMduct or ESTmep prior to it’s acquisition by Autodesk remember when all the reports were in one folder. Once Autodesk took over, they moved to a system where each product used a separate subfolder for their reports. After all, ESTmep is likely using different reports than CADmep and yet different than CAMduct. Here’s what your configured reports folders now look like (you may not have all products/folders). Notice how each product has it’s own older.

The reality is, many reports are helpful across products. This means you need to make the same report multiple times or copy it from one folder to the others. This leads to duplication of data and a chance than one of the copies gets changed different from the others.


Consolidating All Report to a Single Folder

It’s commonly asked if it’s possible to configure the different Fabrication product to use the same folder. The answer you always hear is No. Technically that’s correct. You can’t configure Fabrication products to look at the same folder. However….

You CAN configure Windows to make multiple folders look at the same folder. It’s just done at the Windows level with a feature called Junction Links.

So lets walk through how to configure CADmep, CAMDuct and ESTmep to all look at the same reports.


Step 1: Find Where Your Reports Are Located

Using CAMduct or ESTmep you can pick Help -> About or type AppInfo at the command line in CADmep. You can then scroll through the window to see where the Reports are located. Alternatively, you could use the Edit Configuration utility to find this folder as well.

Note that this screencap was done in ESTmep so you see the ESTmep subfolder. The mis folder is actually the root where all your reports are.


Step 2: Copy All Report Folders to a New Folder

The next step is to copy all the reports from the various product specific folders to a new master folder location to store the reports. In this case, we’ll call it (Master) just to make it super obvious. Notice we also deleted the folders for CAMductComponents, Tracker and RemoteEntry because I’m not using them. You can choose to include them if you need them,


Step 3: Backup and Delete the Original Reports Folders

When you’re done, you should back a backup of the product specific reports folders elsewhere incase you want to go back to the original config. Once backed up, you need to delete the original product specific reports folders. When you’re done, your reports folders will look like this…


Step 4: Create Junction Links for the Product Folders

Here’s where we do the magic. Windows allows you to create what’s called a Junction to other folders. A Junction is just another virtual folder that looks at the contents of another. Junctions are how Windows has a “My Documents” folder that really points to “C:\Users\<Username>\Documents“.

To create a Junction you need to open a Command Prompt with Administrative permissions. One that’s done, you use the MKLINK command to make a Junction Link to a Junction Target. The syntax looks something like this….

MKLINK /J "link folder" "target folder"

Here’s a screencap of my DOS Command Window where I make Junction Links to the (Master) reports folder…

When done (if Successful) you’ll see those product specific folders again for CADmep, ESTmep and CAMduct. But this time, you’ll notice the icons are slightly different and look like a shortcut icon even though the folder acts like a regular folder.

Here you can see a side by side recording of the process happening in real time…


Step 5: Use Fabrication As Normal

Once you have the junctions created, you can use your products as normal. Each fabrication product looks to the folder specific to it, which Windows redirects to the file in the (Master) folder.

One thing to note, is that when browsing the (Master) and product specific folders, the only clue that these are Junction Links is the Shortcut looking arrow on the icon. If you don’t know what’s going on, it would appear that you have 4 folders each with the same files. But if you try to delete the files in one, they will indeed disappear from the other folders too. After all, these folders are Links back to the Target.

Here’s a recording of all 4 folders show at the same time. You’ll see that changes to any one also happen to the others. You may need to Refresh the views to see the changes but they indeed are seen from the Target and all Junction Links. This means that while there’s 4 folders showing the same files, they only take up the size on disk in one folder.


Summary

Junction Links work well for letting all (or some) of your Fabrication products use the same list of Reports. But there are a few noteworthy items to be aware of….

  • Junctions Links and Point to Targets on a different DRIVE or FOLDER as long as it’s on the SAME machine. You can’t make a link to a target from a computer to a server for example.
  • If you access your database from a network location, you need to make make the links from the server so your IT Department may need to get involved. Your local software when accessing the server share will honor the junctions it sees on the server.
  • If you don’t know what’s going on or look closely, it appears you have duplicate data. Make sure you don’t delete things from one folder thinking they’ll still be in the others.
  • If you want to undo this setup, you should delete the Junction Links FIRST just like any other folder before deleting the Target folder. If you delete the Target first, the you’ll have trouble deleting the links.
  • IF you Sync your database from a master source location like Dropbox or using a utility like Robocopy, the Junctions are NOT copied, but are instead copied like regular folders. There may be some special utilities that copy the junctions but I’ve not found them. So what is 4 views of 1 copy of a file on a network, when synced to your local system becomes 4 copies of the files in 4 folders. For the most part, it’s not an issue as you manage from the master source location. None the less, this nuance is worth mentioning. Most Sync utilities do NOT recognize the special nature of a junction and treat them just like a folder.

Autodesk Fabrication – Determining C1/C2 Connectors in Revit

Fabrication Parts in Revit allow you to edit their connectors just like in CADmep. However, unlike CADmep, you can’t simply hover over a connector to determine if it’s C1 or C2.

So if you need to change a connector, you’re essentially guessing which one to change. Trial and error is at best 50% unless you’re lucky.

So how can you improve this “guessing” based workflow?

Thankfully I have a great network of people smarter than myself. I often get the credit for sharing the information but really, the credit belongs to those who show me. In this case, two of my industry friends showed me ways to improve the odds.


Method 1 – Slope

For this first method, credit goes to Liz Fong from MacDonald Miller. When you place a piece of straight pipe or duct, when you select it you’ll see a Slope indicator (< or >). This by default points to the C1 connector.

Duct/Pipe placed defaults the Slope symbol pointing to C1
Duct/Pipe mirrored also defaults the Slope symbol pointing to C1

There’s a couple downsides to this approach that may apply in some scenarios….

  1. This doesn’t work for fittings. Only Straight Pipe/Duct.
  2. If you click the Slope Symbol, it changes direction and is no longer accurate.
    • This should really only affect Plumbing or sloped Grease Duct systems. Otherwise there’s not a lot of reason to change direction on a non-sloped system.
    • Symbol could still be accidentally clicked and reversed anyway and then be wrong.
  3. Once changed, Slope symbol direction is remembered and there’s no good way to “reset” it.

Still, despite the downsides of this approach, I’m going to go out on a limb and suggest that even on a plumbing system, less that 50% of the slope symbols will be changed from their default. This alone makes this method better than a 50/50 guess like before.


Method 2 – View Cube/Viewing Direction

This next method takes slightly more work, but is almost 100% accurate. Credit for this method goes to Alina Y. from JH Kelly.

In short, from a 3d view, if you make sure the View Cube in the Part Editor window is aligned to the Revit View you’re in, the fittings is oriented in the same direction in the editor as in Revit. You can then select the connector in the Part Editor window and it highlights the connector end associated with it.

Duct/Pipe placed in Revit matches the editor when View Cubes are aligned. Selected Connector highlights.
Duct/Pipe mirrored in Revit matches the editor when View Cubes are aligned. Selected Connector highlights.

This method is almost fool proof and has a few benefits over the sloped method we showed earlier.

  1. Works on Fittings in addition to Straight Duct/Pipe.
  2. Slope direction doesn’t matter.

But we did say Almost. Where this method fails, is if the View in Revit is redefined.

When you set a new Front View, the view in Revit no longer matches the orientation in the Part Editor window as seen in the following image…

Luckily, this is easily remedied by simply resetting the Front View in Revit.

This method also works in Plan and Elevation Views with a slight twist. There’s no View Cube in the Revit window so it’s up to you to understand which viewing angle Revit is in. Next, you can make the View in the Item Editor match but when you look at a connector straight at the edge, you don’t see it highlight. You can then hold the SHIFT key and use the Middle-Mouse Button to slightly rotate the view so that you can see the connector that’s highlighted.

Here you can see what that looks like…


Summary

While not as quick and efficient as hovering over a connector in CADmep, either of these methods or even used in combination can increase your odds of changing the Correct connector on the first try.

While method #2 is more fool proof than method #1, there’s a reason I explain both and here’s how I’d use them both.

For non-sloped systems, the chances the slope symbol is reversed is very low. Because you’re likely selecting the part anyway to edit a connector, a quick glance is all you need to know which connector to change. Quick and easy for straight part on non-sloped fittings. No fuss. No muss. In this scenario, Method #1 is super quick.

For fittings and sloped systems, I would then shift to Method #2. Take a little more time, but it’s certainly quicker than being wrong 1/2 the time and then undoing the connector you just changed and then changing the other. That “trial and error” method results in 3 connector changes when you guess wrong. This is where Method #2 really shines…you get it right every time. If you’re Front View happens to be redefined, it’s easily rest.

Thanks again to Liz Fong (MacDonald-Miller) and Alina Y (JH Kelly) for their great input in coming up with these methods. They’re two of my favorite “Go To” people when I get stumped or need a little help orienting my thoughts.

Autodesk Fabrication – Profile Error w/UNC Paths

If you use UNC pathing to get to your Autodesk Fabrication Database, you might find issues when trying to create Profiles if you use them. UNC pathing or (Universal Naming Convention) is where you specify a server and share vs a drive letter. You can see below, the Metric Autodesk Fabrication Configurations is using a UNC path…

When using this configuration, you can create a profile from the File drop down menu in ESTmep and CAMduct or by typing MAPPROFILES in CADmep.

Creating New Profiles

You go to create a new profile by clicking the Green button.

From here, the New Profile dialog starts with the default name “Untitled”. Notice also, the double leading forward slashes before the server name in the UNC path. (Yes, ‘little-stink’ is the server name)

When you start to type a profile name, the leading forward slashes get stripped. This is likely a bug. You can see that in the following image…

If you click the OK you’ll get an error that the profile can’t create the required folder.

However, the fix is easy. If you just add the leading forward slashes again, you” be able to create the profile.


It may be easier to see from a video. You can watch the process here…

Fabrication 2022.0.1 Update Released

Update: 2022.09.04

It’s recommended NOT to install this update for CAMduct or ESTmep. Installing the 2022.0.1 Update will prevent access to the Projects folder. CADmep does not appear to have issues with this update.

Thanks to Chris Nash of William R. Nash Company for reporting this issue on the XtraCAD.Com forums.

It’s been a long time, but Autodesk finally released an update to Autodesk Fabrication. 2022.0.1 Update was released recently and contains several fixes for 2022 versions of CADmep, CAMduct and ESTmep.

Install from the Autodesk Desktop App or download from your Autodesk Account portal (https://manage.autodesk.com)

Autodesk Fabrication: Best Practice #14

Eliminate All Broken Service ITM’s

Your services should not have broken links to ITM’s. Not only is it sloppy database management, it can slow performance of your database.

Use the Path Repair Tool to find (and fix) broken links in your services.

Right-Click and empty area of your Service Palette and select Path Repair Tool.

When you run the Path Repair Tool you’ll be asked to select a mapping file. You can click cancel and the tool will continue on. When it’s done, you’ll have a list of broken paths copied to the Windows Clipboard that you can paste into a file.

From this file, you can then create a mapping file. The mapping file is merely a text file in the format….

OLD PATH/NAME,NEW PATH/NAME

So the data you paste from the clipboard is good starting point, it lists all the broken paths. There may be duplicate paths listed if the path is used in multiple service templates. It’s ok to remove the duplicates.

Simply ass a comma after the broken path name and enter the new, corrected path. Once done, you can save the file and use it when you run Path Repair Tool again. It’ll then go and fix all those broken paths.

NOTE: This repair technique does NOT work if you have commas in your folder or file names. (See Best Practice #11)

Autodesk Fabrication COD Object Model

I’ve added graphics to better illustrate the Autodesk Fabrication Object Model for COD Scripting,

If you write COD scripts for CADmep, ESTmep or CAMduct, this can help you better understand how the various properties and objects are structured when you write your code.

If you want to learn more about Fabrication COD Scripting and how to use these resources, register for MEP Force 2021 and look for my Fabrication Scripting sessions.

Autodesk Fabrication 2022 Updates

Autodesk Fabrication 2022 marks a decade that I’ve been updating various documentation for the program. As usual, in recent years not a lot has changed but there are a few changes. Here’s a review of the changes for the data I track…
