DXF generated by Autodesk Revit not displaying correctly

[jdh-invicara]

When I open a 3D DXF file in the dxf-viewer I would expect to see a top-down view. This works as expected with output from Rhino.

Here's a 3D model generated from Rhino displayed in Autodesk DWG Trueview:

Here's the same model with camera orbited to look top-down:

And here's the same model when loaded into dxf-viewer-example:

However, when I open a DXF file generated from Autodesk Revit model's 3D view I get "extra lines drawn".

Here's a DXF output from a Revit model in Autodesk DWG Trueview (viewed top-down):

And here's the same model when loaded into dxf-viewer-example:

Here are the two DXF files - one from Rhino and one from Revit:

Thanks! Such kind of sample files are very valuable for the project. I have figured out that the problematic file uses POLYLINE entity kind called "Polyface mesh", which proper support is not yet implemented. Will try to fix it soon.

Fixed in v1.0.23. Demo page updated.

Note that wireframe rendering of meshes is controlled by sceneOptions.wireframeMesh options which was false on the demo page. I have set it true now which probably better suits common use cases. One day will make some control in UI for that. Without wireframe it is now rendered like this:

Wow - fantastic! Thanks :-)
