Dwg xref origin bug
-
dwg and dxf exports used to export with a random origin so that you couldn't consistently xref it into your autocad drawing. Does anyone know if it was ever fixed? I've just come accross the problem again and it's quite annoying! There's a "preserve origin" option for imports but none for exports.

Hey Rob,
Can you give me more information on this problem? I'm not sure I understand what the problem is or what you are trying to do? You are using XREF in AutoCAD of an exported DWG from SketchUp? I searched our database and didn't find any sort of DWG export origin problem. Of course, I'm not sure if that's the problem.
Thank you.

Brad, Rob,
What Brad says is valid for 3D model exports from SU to DWG, but in 2D exports the origin gets placed in the middle of the current view, and there is no way to place it elsewhere. Maybe making a scene and reverting to that always when exporting would produce accurate enough results? Must make a test - wonder if the results are consistent across different displays, computers and SU window sizes.

Hi Brad, Anssi
I'm exporting from sketchup to dwg, then xref-ing these files into Autocad. Whenever I change something in SU, I then re-export the dwg and "refresh" the xref in autocad. The problem is as Anssi says. When my drawing gets larger or smaller in Sketchup, the origin of the exported dwg file changes, so when I refresh in autocad... the xrefs move!
Anssi - good idea on setting up the views. Unfortunately, this is the way I have been doing it, so it doesn't solve the problem.
Brad - any help you can give on this is much appreciated. It's the fly in the ointment for me at the moment. I'm evaluating the SU/Acad combo as a BIM solution with a view to getting it adopted company wide, and without a fix on this I can't really recommend it.
Kind regards
Rob D
