Autodesk Forge messed up view

Question

We are using the Autodesk Forge model derivative and viewer API's for sharing Revit models with our customers. This works very well for almost all our Revit models. But currently we have 2 Revit models which use the same template, and with those 2 models the Forge viewer does not render these correct. It looks like we get some kind of exploded view, materials are not on the correct place etc (see images).

We assume it has something to do with the Revit template, but we cannot find it. Any suggestions?

Answer 1

As a suggestion, on Revit, go to publish settings and confirm the names of the 3D selected to be extracted. On Viewer, ensure you're showing the same view, you can see the name where you load a specific viewable.

Answer 2

I have found a workaround, it looks like the problem was the cars which I was using in the model. These were Revit families where a DWG import was used. When removing the cars from the model all other materials where rendering fine in the Forge Viewer. I sended the model also to Forge support and hoping for a solution so I can use the cars again.
