SketchUp Curves and Revit/AutoCad DWG imports

Hello Everyone,

I’ve been converting Revit files for our designers for a while now. I’ve got my preferred method of changing the settings so that everything imports cleanly and we can run with it without having to rebuild anything. However the curves are the frustrating thing. Everyone knows how SketchUp handles curves, and as a result when importing a DWG you get the default segments on all the arcs in the file.

For example I had to rebuild most of the ceiling in one particular file before handing it off because of the fact that the architects designed so many curves and SketchUp defaulted to 12 segments for all of them. I’ve read through several forums and have yet to find a good resolution.

I’m mainly asking because our company is planning on moving to Revit and Autocad to help manage alot of the projects. However I would put money down that the designers won’t learn Revit, so we’ll have to use SketchUp still for quick ideation and presentation while Revit manages our schedules and project data. It’s all setup in Revit on the front end and then adding and linking information from the design team as they work through SketchUp.

Anyways. I’m probably going to have to rebuild our casework/design elements so that we can link them to our running Revit management and I’m trying to find a way to keep the curve thing from undoing any intense modeling I do to make it smooth and accurate. I’m faster and have more capability in SketchUp so modeling families in Revit is pretty much out of the question.

Does anyone have any method for keeping curves smooth between the two programs. I know it all comes down to the fundamental difference between how they handle geometry. But if there’s a way to force it disregard that default arc setting I’m all ears.

Thanks for the help,


you might wanna check if the ‘AMS Soften Edges’ plugin can improve the smoothness of the polygons.

That does have some affect. While it smooths them visually it doesn’t add segments to the curves and surfaces which is primarily what I was looking for. Definitely a handy plugin though so thank you for that.
