I am currently working with a 3D DWG file trying to get it into SketchUp but I am running into some problems. I’m not familiar with AutoCAD’s 3D features so I am hoping someone can enlighten me.
The DWG I was given has many curved surfaces with some flat edges. The flat edges come through after I explode each block, but the curved surface does not (left object in both screenshots). I am able to convert that surface to a mesh and explode it in order to get something into SketchUp (right object in both screenshots). However as you can see this breaks the curve of the surface and creates a pretty big gap. Obviously to some degree that curve will be segmented coming into SketchUp, but is there a better way so it’s minor or matches the segmentation of the flat objects?
Not really knowing the differences between 3D cad objects, the only thing I’ve been able to determine with any certainty is that SketchUp does not like Regions. My flat Surfaces import fine, but not the curved one. An unexploded Mesh does not import, but an exploded one does.
In theory I could use CAD’s 3ds exporter but I will quickly hit the face limit in the original model, and I would prefer to avoid copying out and reassembling each piece individually. Exporting to FBX also does not produce anything usable.
What’s the best way to convert the file? Any tips are appreciated!
