AutoCAD Closed Polyline Not Importing as Face in SU

Hi Everyone, I have a set of closed Polylines in AutoCAD that I’m trying to import into Sketchup. All but 1 imports fine and creates a face, but the last one won’t create a face. The lines are too complicated to trace over to create a face. Please help! I have uploaded the CAD, Sketchup, and a screenshot showing the area that isn’t importing. Please help! I have looked at many of the other topics on this forum, but none of the solutions I’ve found there helps me. Thank you!

So, did you find a tiny gap in the SKP? I did?

Hello, @IanT!

There was no gap either in DraftSight nor pCon.planner (for SKP export).



In SketchUp 8, I just drew those lines to create the surfaces, as shown in the clip. I did not look for any gaps, because they all correctly closed (even the islands).

You’re welcome, sklein!

Hi Mihai,

Well, I’m baffled. I only got the face using the OPs file in 2019 after I fixed the gap. I also got the gap when I imported the DWG into SketchUp myself.

Zoom right in on that part…

Zoom right in again, there’s still a gap…
