Design to LOD 350, From FabCAD to Revit, Insulation not visible on Duct

[Anonymous]

I have a design model which I am attempting to convert to a LOD 350 duct model for coordination.  I have exported the design model, opened it in Fabrication CAD MEP, then sent the .maj file back to revit.  I open it up in revit it all comes together as it should.

When I try to change the Insulation Specification to a 2" Insulation or any insulation for that matter I do not see any changes in the model.  If I manually place a piece of Fabrication duct and add insulation it shows up. 

 I am using the same Database between Revit and FabCAD. I've tried it with Revit MEP Imperial Content V2.1 and Imperial Content V3.05.  I am using Revit 2018 and FabCAD 2018.  I added a new insulation specification and reloaded the database in Revit to make sure I was using the same one. 

I've checked to make sure my MEP Fab Insulation layer was turned on in Visibility Graphics.  I've created the model in a completely new Revit Project and nothing?  

Any help would be appreciated.

Hello @Anonymous ,

If I'm understanding correctly, You export a MAJ from Fabrication, import the MAJ in Revit, and then attempt to apply insulation. The existing items brought in from the MAJ do not show insulation, but new items placed will show insulation?

I have the following questions to see if we can narrow down what is happening:

• Are the items in the MAJ within the same service as the fabrication items you are placing in Revit?
• If you add the insulation to the items in Fabrication CADmep, before exporting to a MAJ:
  • Does the insulation show up in CADmep?
  • Does the insulation carry over within the MAJ to Revit? 
• Are you able to share a sample MAJ and/or Revit file with the issue? 

Thank you in advance for the extra information!

Thank you for getting back with me.  You questions have given me some ideas.  I will try some things out, then I'll get back with you.

Awesome! Let me know if you run into any issues, or have questions or concerns.

See below for replies to your questions....

• Are the items in the MAJ within the same service as the fabrication items you are placing in Revit?Yes, they are the same.  I believe you are referring to the test objects I am placing?
• If you add the insulation to the items in Fabrication CADmep, before exporting to a MAJ:
  • Does the insulation show up in CADmep?  It does... 
    • Does the insulation carry over within the MAJ to Revit?   It will...
    • So I tried this out to see if it worked and I found that if I add the insulation in CADmep then it will show up in revit and I can change the insulation spec on the parts... I suppose I could do it this way.  I am concerned I will missing something in the transfer process and will find a part(s) later that won't let me add insulation..  Not the end of the world but I'd like to be able to manage this from revit if possible?
• Are you able to share a sample MAJ and/or Revit file with the issue? 
• I have created a sample set of files for you to look at, you will notice I added insulation to one of the systems, this was done using the method above, in CADmep, then sending it to Revit.  The others do not have insulation and do not turn on..  I sent a sample revit file(after import of CADmep/sample CADmep file and sample .MAJ file.... look forward to hearing what you think.  

Thank you for the Help

I figured it out...

I had to add insulation to the design model in Revit before sending to Fabrication CADmep.  Once in FabCAD I had to turn on all the insulation following the reverse of this method

Then I exported to Revit, and the insulation shows up, now I can change the insulation to whatever I need to.
