Field Ordering Ductwork

Want to Field order ductwork electronically? There’s several options that I’m aware of.

Autodesk Remote Entry

Autodesk’s Remote Entry can be installed on any number of computers without cost just as long as you have at least a single license of Fabrication CAMduct (~$1000/yr). You can read about Remote Entry’s licensing details here. Remote Entry is only of value if you’re shop or your duct manufacturer uses Autodesk’s Fabrication CAMduct to drive fabrication.

Note, like most of Autodesk’s Fabrication software…this is a stagnant product. Works only on Windows (no Andriod or IoS). Unless you’re already using CAMduct in your shop, there’s littererly very little reason to ever implement this software.

BuildCentrix

BuildCentrix started out as Webduct. They’ve since expended beyond ductwork and gone as far as having capabilities to integrate with a number of ERP systems. This is likely the best “Enterprise Class” tool focusedon ductwork at this time.

FieldOrderZ

One of the newer players in the market, it’s a project partnered with GTP. However you don’t need to be a GTP Stratus user to leverage FieldOrderZ. It can serve your needs even if you’re not a Stratus customer. It can also facilitate more than just Ductwork. Works best for Autodesk Fabrication users but I’d encourage you to reach out to them to see what they can do if you’re not an Autodesk Fabricatino customer. Likely one of the easiest tools for your Field staff to sketch what they need without being an AutocAD or Revit savvy detailer.

SiteTrace

SiteTrace is another newcomer I’ve just become aware of. CAD Content agnostic, it’ll help digitize your field ordering of Duct and related accessories saving you time and errors from traditional processes. They don’t integrate with any CAM software or Machine tools at this time making it the perfect fit for those smaller shops that get overlooked by the larger software companies.

Trimble FabShop

This is the old Vulcan software, one of the long timer CAM platforms for Duct fabricators. Their current platform has mobile capabilities that allow Field ordering of duct and processing within Trimble’s Shop Fabrication software.

Vicon Vi-Call

Most pepole know Vicon as a builder of Duct fabrication machinery. But they also offer a varierty of software tools. One of which facilities ordering of ductwork from your field staff to the shop into their managment platform.


If you’re aware of other field ordering tools for Sheetmetal ductwork, drop me a note and I’ll get them added to the list.

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 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)

Fabrication COD Script Library – Updated

If you’ve not downloaded the Autodesk Fabrication Script Libraries lately, you might want to grab an updated copy. There’s been several updates over the last month. Here’s what’s changed…

  • Damper Rotation Property (undocumented) has been added to all Debug, Job and Library scripts. Support for this property was added in 2017 but never documented. It’s there to support the rotation of Dampers on Fabrication Parts in Revit. It should be noted, that this value is Added to the Angle property of the assigned damper. As such, it acts as an Adjust and not an Override. e.g. Damper w/Angle of 90 + Rotation Property in the ITM of 90 results in a damper rotated 180 degrees.
  • Stiffener Group Property added to the Autodesk Fabrication 2022.0 and later versions of the Debug, Job and Library scripts.
  • Airturn Group Property added to the Autodesk Fabrication 2022.0 and later versions of the Debug, Job and Library scripts.
  • Splitter Group Property added to the Autodesk Fabrication 2022.0 and later versions of the Debug, Job and Library scripts.
  • Insulation StatusLock Property added but listed as “Unavailable” as it stopped working in 2017. Added in the hopes it gets fixed in future versions.
  • StructureType Property added to the Autodesk Fabrication 2022.0 and later versions of the Debug, Job and Library scripts. Property was “Write Only” in 2021 and prior versions so was unable to display in prior versions.
  • Product List HasCustomData Property has been added to all Debug, Job and Library scripts.
  • Product List HasFlow Property has been added to all Debug, Job and Library scripts.
  • Item PCFSKey Property has been added to all Debug, Job and Library scripts.
  • Item CostByLength Property removed from Material Debug scripts (never really belonged there).

You can find the updated scripts here….Script Library.

New Properties are documented here…Item Property Reference.

Script Library Updated / Enhanced

COD Script Library was updated for JOB and LIBRARY Scripts. You can download them for free here. Here’s a summary of changes.


Script Consolidation

In the past, there were 69 to 75 COD Scripts to export all the various properties to separate TXT files. Properties that have multiple entries per ITM like Connectors or Seams are still exported to separate files because the data columns don’t line up between them and there are multiple lines per ITM.

All other properties where it’s a single property per ITM like Spool or Material have all been consolidated to a single script and single TXT file. The WriteAllMiscProperties(Job).cod and WriteAllMiscProperties(Library).cod scripts are where you can extract all other properties so no matter what combination of properties you want, there’s less data files to sort through or scripts to run.


Improved Script Properties Display

The properties scripts were displayed script settings before running the script. They still are but additional properties are displayed where appropriate along with some additional properties the scripts now support (both covered later). In addition to the additional items, you’ll note that clicking the No button no longer cancels the script. Instead, clicking No takes you to the Advanced Configuration (also covered later) where you can change some of those settings.


Advanced Configuration – Scan Folder (LIBRARY Scripts Only)

By default, the script looks to the root of your ITM Library folder of your database. This value can now be changed to point anywhere else. You may want to point to a folder of ITM’s outside your Configuration if that’s where you store your ITM’s. You can also scan further down the folder structure so you can perhaps skip exporting Duct ITMs but instead scan and export Piping ITMs.

Here’s what this looks like. Note that the path may use forward slashes ( / ). You can however paste a new path that uses backslashes ( \ ) and it should still work. There’s no option in COD Scripts to allow you to browse to a folder so make sure you type or copy/paste carefully.


Advanced Configuration – Export File (JOB and LIBRARY Scripts)

Similar to the Scan folder configuration, you can now also change the default export file name and location. Specifications for specifying paths are the same as above.

Also note that while you CAN specify “CSV” as the file extension, I recommend using “TXT“. When Excel sees a CSV file, it just opens it without giving you the ability to specify how data is interpreted. Using a “TXT” extension makes Excel prompt you for “How” the file should be read like which character is used as the delimiter or defining which columns are Text vs other data types.

Some numerical data or values can be interpreted incorrectly by Excel if you don’t explicitly tell Excel to treat them like Text. A good example of this is the size 1-1/2″ or 1-1/4″. Excel thinks these are dates and will display them as 1/1/2012 or 1/1/2014 respectively if you don’t explicitly tell Excel to treat them as Text. Using that “TXT” extension on the export file is a safe guard against this issue.

A lot more detail that you likely wanted but hopefully it’s helpful, here’s what that looks like….

Note you may see an extra slash character between the path and file name. This is can happen if your MAP.INI (Edit Configuration Utility) includes or doesn’t include an ending slash. I may add code to clean this up later but COD Scripts and Fabrication seem tolerant of this extra slash so no need to worry about it (or edit it out if you like).


Advanced Configuration – Folder/Path Wildcard (LIBRARY Scripts Only)

Instead of editing the folder you’re going to scan, alternatively you can specify a wildcard to use to limit which folders to export data from. As an example, you could specify *WELDBEND* and properties will only be extracted for ITM’s within folders containing the name “Weldbend”. Wildcard specification is not CaSe SeNsItIvE. By default, the wildcard is ( * ) to extract from all folders. Here’s what that looks like…


Advanced Configuration – File Wildcard (LIBRARY Scripts Only)

Just like the Folder/Path Wildcard specification, you can specify a wildcard for which ITM files to extract properties from. As an example, you could enter *PIPE* and you would export only from ITM files that contained the work “Pipe”. Again, the wildcard is not CaSe SeNsItIvE. You can use both Folder and File wildcards to very narrowly specify your data export scope. Default wildcard is an ( * ) to extract from all ITM files. Here’s what that looks like…


Advanced Configuration – Delimiter (JOB and LIBRARY Scripts)

Data exports by default use a Comma ( , ) to create a Comma Separated Value file. If your Fabrication Database uses commas in folder names or ITM file names this can cause data fields to shift in Excel when opening the export file. If this is the case for you, you can specify a different character to use to separate the data fields in the export file. The Pipe ( | ) character is always a good “rarely used” character for this purpose.

As a side note, it’s not a good practice to have commas in folder or file names. You can read more about that here. This option is really here in case you’re stuck with commas and haven’t fixed them yet.


Advanced Configuration – Max Custom Data Index (Only Scripts that export Custom Data)

Only used for scripts that export Custom Data, you can specify the maximum Custom Index value. Unfortunately, COD scripts have no ability to determine how many custom data entries you have or which index numbers are used without jumping through some hoops. To work around this, you need to specify the maximum Custom Data Index value. The script will then loop through all those numbers and find which ones contain values and remembers them. It then exports only those custom index values so that the script runs efficiency.

By default the script uses 5000 as the maximum index number. But as you can see from the below example, the maximum index number is 10000 so we need to specify that. We look at all 10000 possibilities (it goes fairly quick) and takes note that there’s only 8 indices used and then extracts only those 8 from the ITM’s. In the past, the script would loop through all 10000 for each ITM really slowing things down. Now, even if your largest number is 6 or 7 digits (not recommended) the script will still be fairly quick.

Here’s what that Delimiter Character configuration option looks like…


Summary

In the past, if you didn’t like the export files names, where they went, or wanted to change the scope of which files or folders you extract data from, you could have always changed the COD script code yourself. You now shouldn’t have to. Hopefully this makes running these scripts a little more flexible and user friendly.

COD Script Extension for VS Code

If you write COD Scripts for Autodesk Fabrication, take note. There’s now an Extension for Microsoft Visual Studio Code (VS Code) which is Microsoft’s free code editor. If you use Notepad or Notepad++ to edit your code today you may want to consider switching. The COD Extension has some really nice features. Color coding of your code is the most obvious as shown below. However, there’s a lot more than just color coding. Features like Auto-Complete, Folding Sections and Dimension/Option Picker are nice additions in addition to a lot more robust documentation.

Installing The Fabrication COD Extension

If you don’t already have it, you can download and install VS Code here…https://code.visualstudio.com/. Once installed, go to the Extension section, type FABCOD and click the Install button.

Extension Summary

Once you’ve installed the Extension, you can review a summary of extension details here…

From here, you can review a couple of the key features and their keyboard shortcuts….

VS Code Feature – Mini-Map

Not a feature of the extension, but one reason VS Code is a nice editor is the Mini-Map which helps you visualize where you are your code.

FABCOD Extension Feature – Folding

One of the features the FABCOD extension exposes in VS Code is the ability to collapse/expand sections of code for Looping and Conditional function and other areas. When you move your cursor to the left margin, you see symbols that activate this functionality called Folding.

In addition to Folding sections of code, you can create your own areas of code to collapse/expand. These are Folding Regions and can be inserted (or typed manually using the proper syntax) by highlighting the code and pressing CTRL+SHIFT+/.

FABCOD Extension Feature – AutoComplete

Auto-Complete is another core feature of any code editor. VS Code’s Auto-Complete features is leveraged by the FABCOD extension. You’ll need to be editing a saved file with a COD file extension so the VS Code extension knows which code extension to use.

ABCOD Extension Feature – Hover Tips

If you hover over known functions/properties and their context can be determined, VS Code will display a tooltip for the function you’re hovering over. This can be a great way to learn coding as it’ll help you with the syntax.

FABCOD Extension Feature – DIM / OPTION Picker

One of the best features of the FABCOD extension is the ability to get suggestions for the Dimension (DIM) and Options. You can activate the DIM picker with SHIFT+F1 and the OPTION picker using SHIFT+F2 keyboard shortcuts. When using these features, you are presented with an edit box. You type the CID/Pattern Number you’re interested in and press Enter. You are then given a list of Dimensions or Options you’re interested in. It’s not fool proof because some patterns have variable DIM/OPTION values but it seriously helps none the less. Take a look here…

FABCOD Extension Feature – Additional Help

Sometimes you need added help for a function. The FABCOD extension is an open source project on GitHub (https://github.com/AgileBIM/FabCOD). This project contains added help for every function and property and is Auto-Generated and updated as the extension is developed. You can access this help from any of the popup ToolTips by clicking on the BLUE hyperlinked text.

FABCOD Extension Feature – AutoCAD Launcher

One of the other neat features of the FABCOD extension is the AutoCAD Launcher. Pressing F5 in the editor will initiate the script in CADmep. Simply Alt-Tab to AutoCAD and press enter. AutoCAD and CADmep must be loaded at the time for this to work. Due to Autodesk’s limitations in their API’s, this functionality does not work with ESTmep or CAMduct.

VC Code FABCOD Extension – Wrapup

There’s a lot more to VS Code that I won’t get into here. I’ve only covered the highlights of how it and the FABCOD extension can be used to help edit COD file in Autodesk Fabrication. As it’s an open source project, there’s instructions on how to become involved if you have the coding skills. You can also just head over and log issues or suggestions.

Fabrication Job Contains No Parts – Possible Fix?

Have you ever tried importing an MAJ into Revit and received the following error….Fabrication Job Contains No Parts.

There’s a lot of reasons this can occur and it’s NEVER because there are no parts. So much for Autodesk’s QA/QC and Error checking.

You may see this most commonly because parts used in the model contain data that’s no longer in your database. You’ve likely noticed from time to time database entries with curly braces around parts of the name like the following…

This happens when an entry in the database is used by an ITM but the database entry itself later gets deleted. Information is cached within the ITM so when it’s accessed, it creates a Proxy entry in your database if it was missing. Within the {Curley Braces} is the name of the object that created the entry.

While CADmep, ESTmep and CAMduct handle this fairly gracefully, Revit on the other hand does not. When it attempts to load an MAJ, it sees these entries and notices they’re missing from your database and prohibits you from importing the MAJ file. Revit thinks the database doesn’t match the MAJ and stops you cold!

A Possible Fix

If this is cause for the import error, you can use the following COD script to potentially work around the issue….

Take the following script and run in in CADmep, ESTmep or CAMduct. You should be logged in with Administrative Permissions while doing this. This script isn’t fixing Revit or the MAJ. What it’s doing is loading ALL the ITM’s from your Database Library into memory.

The process of loading all these ITM’s into memory creates all these proxy entries in your database. This way, when Revit attempts to import the MAJ, the data associated with those ITM’s are most likely present in your Database configuration. In many cases then results in a successful import of the MAJ.

If the Revit file you are importing the MAJ into already points to a Fabrication Configuration, you should reloaded the configuration FIRST before attempting to import the MAJ.

If for some reason this process still doesn’t work, verify that Revit is reading from the same database location as the version of CADmep, ESTmep or CAMduct where you ran the COD script.

In the event it still doesn’t work, there may be other reasons for the failure but this is often the most common, especially with MAJ’s created recently.

If it does work, you’ll want to use the other scripts I provide on this site to help analyze your database. You likely deleted those database entries in the first place for a reason. You either didn’t realize they were needed, or you didn’t know where they were used to repoint those ITM’s to a proper substitute. Those scripts can help you find which ITM’s use which database entries.

Hope this helps.

Autodesk Fabrication Scripting – Did You Know?

In the list of COD Scripting updates I just posted, there’s a couple undocumented functions that have been on my list to explore for more than a few years. I’ve finally gotten to them and figured out what they do.

I won’t comment on how long it took me to actually explore what I had listed in my “To Research” list for years other than to say, Procrastination is a Virtue for those with no Patience.

So without further delay…here you go….


Output Function

This first one is the OUTPUT function. You can call it a couple different ways, with and without parenthesis just like the DEBUG function. It doesn’t really seem to matter. It’s really kind of a worthless function in my opinion.

Not only does it only work in CAMduct and ESTmep (not CADmep) it really isn’t that helpful. It just outputs a message to the Console window. I was initially hopeful it would allow me to “script” some of the secret Console command but no such luck. It’s just a message.

You can see in the COD Code editor the below with both syntax examples…

When you run the script, it’ll call up the Console and display the text you specified. You can see from the following example, it doesn’t even space the text when you call it multiple times. Even tried embedding a Carriage Return in the string and still no luck automating via the Console.


Breakpoint Command

The other command is much more helpful and something most folks don’t know about. I have run into a couple now who knew but most it’s not known. I wish I knew years ago…it’s actually a small step closer to what you’d expect in a modern IDE (Integrated Development Environment).

The Breakpoint function calls up the panel on the right. It displays the values of all your variables. You can see how the value of the “z” variable is displayed. When you hit a Breakpoint, code execution stops until you hit the green arc’d arrow. Code execution then continues until you get to the next Breakpoint if any.

You can access the COD Script editor in CAMduct or ESTmep using the FILE pulldown menu. You can also use the editor in CADmep but unfortunately, there’s no way to display it without writing intentionally wrong code to cause your program to fail and display it. You can then use the editor like you do in ESTmep or CAMduct.

One thing to note, BREAKPOINT only appears to work when you execute code from the Script Editor. If you call it from AutoLISP using (executescript “myscript.cod”) or the EXECUTESCRIPT command in CADmep or by right clicking in your Takeoff items in ESTmep or CAMduct, it runs without stopping your code. This means you can leave the breakpoints in your code and edit/debug via the script editor but not have to remove them when executing them un a production setting.

Fabrication Reference Data Updated for 2021 Versions

Autodesk Fabrication reference data has been updated to include 2021 versions of Autodesk Fabrication software.

Updated references include…

The only change I’ve found in from 2020 to 2021 versions is the CADmep command DWNLDC Command (DOWNLOADCONTENT Alias) is no longer present. This use to download ITM content from Autodesk’s www.Building3DContent.com site. This site is no longer active and Autodesk has included all the content within the default Imperial and Metric configurations that ship with Autodesk Fabrication Content.

User’s of Trimble’s Managed ITM Content (building-data.net) use to use this command as well. It was just redirected to the Building Data site. It’s unclear how this change will affect them as the core DLL’s used for this process appear to have been removed in 2021 versions of Autodesk Fabrication.

If you’re a user of Trimble’s Building-Data, I’d suggest contacting them for support if you have issues.

Merging Autodesk Fabrication Databases (Method 4 of 4)

Warning: This is last part (4 of a 4) in a series on merging Autodesk Fabrication Databases. Autodesk Fabrication software is extremely powerful and flexible but that also makes it very fragile. Use the below guidance with caution. I highly recommend backing up your configuration before attempting anything I’ve recommended. It never hurts to have a firm grasp of how Autodesk Fabrication functions from an administrative perspective. Consider yourself warned!

Method 4: MERGEDB (CAMduct only)

This last method is very quick and powerful but only available in CAMduct. If you’re not a CAMduct user, simply download and install to perform this process while in the 30-day trail period.

This method doesn’t let you pick and choose individual database entries but you can pick certain database types and quickly merge all of them into a new configuration. Unlike prior methods were you typically started in the old Database to export an *.IOX / *.IEZ file or create a Proxy ITM first, in this process, you start with the database you want the items to be imported into.

In addition to make of the database entries Method 1 supported, this method also supports these additional entries.

CutoutsLeadsRates
FacingsMaterialsSilencers
Hanger SpecificationsNotchesVanes

To use this method, start CAMduct and type CTRL-SHIFT-C to display the command window as shown below.

From the command window, type MERGEDB and press <Enter>. This doesn’t do anything other than tell you the data the command needs as shown below. The Strict/Unstrict options tell the merge process if it should only look at the name or the data to determine if it’s duplicate. If you choose strict and the items are already in your database, something as simple as 3 vs 4 digits after a decimal will cause a duplicate entry. In most cases, unstrict is all that’s required.

For this example, we’ll type MERGEDB UNSTRICT NOTCHES to import all the notches from one database to another as shown below.

When you press enter, you’re prompted to select a folder. You should select the Database folder of the old database you want to merge into your current database.

If new items are found, you’ll be notified and prompted if you want to save the changes or not.

Upon completion of the merge, you’ll need to go to those items in your database and make permanent any you intend to keep and remove those you didn’t want.

Pros:
> Only way to import some database entry type.
> Easiest way to merge the bulk of 2 database together.
> Extremely fast and efficient.
Cons:
> Requires CAMduct.
> Can not pick and choose database entries, only database types.
> Requires post merge cleanup of deletion or making entries permanent
