Fail to read an IFC file on Trimble Connect Desktop

Question asked by Olivier Pellegrin on Nov 30, 2018
Latest reply on Dec 5, 2018 by Marko Myllymaa

Hello,

Some users working on TBC are not able to view any IFC model (coming from Revit or Tekla).

They keep getting this red colour on the model tree within the model viewer.

I think that their computers cannot transform an IFC file into a TRB file. (see picture attached, it stays as a trb.download in his Trimble Connect cache)

 

The weird thing is that on my own computer, I have absolutly no problem reading and viewing any IFC file.

Nobody in my team (3 different persons) can read any IFC file in any project.

The only solution we found is to manually copy/paste the .trb files from my cache in their own cache. When this is done, they can open the iFC models...

This is a huge issue for us as we make extensive use of TBC in our BIM projects.

Please help us.

Thanks a lot

Regards,

Correct Answer

Hi Olivier,

 

It sounds like your colleagues have managed to get multiple versions of import plugins in their machine. And Trimble Connect Desktop 1.6 is incompatible with some older versions of IFC plugin.

To solve this, they need to follow these steps:

1. Uninstall Trimble Connect Desktop

2. Uninstall Tekla BIMsight

3. Uninstall all plugins, they start either "Trimble Solutions ImportSDK" or "Tekla Model Sharing Foundation"

4. Navigate to following folders and clear them:

   C:\Program Files\Trimble Solutions\ImportSDK

    C:\Program Files (x86)\Tekla\Model Sharing Foundation

5. Open regedit.exe and navigate to following path and remove all plugins that are listed there:

    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Tekla Corporation\Model Sharing Foundation\plugins

6. Install Tekla BIMsight if that is needed

7. Install Trimble Connect Desktop

 

Now all IFC models should work again. Trimble Connect Desktop and Tekla BIMsight use the same plugins, but Tekla BIMsight has older versions, thus it's needed to install first. And try to make sure that installations of the software and their updates is done by same user. If IT admin does the installation, they need to do the updates also.

 

Hopefully this helps. Please ask, if you need more info on some steps.

 

Best regards,
