Looking for an education on the subject of exporting for autocad. Is there anyway to retain circles and curves, rather than have them just show up as segments?

Simple answer would be: No. I have not come across any method to do so. Are you trying to manipulate them in different program?

if you increase the segment count of the curve, they would be fine in my opinion. I think other woodworkers may have different idea or solution.

Here is where I’m at: I don’t own a copy of any autodesk product. I am using sketch up to generate geometry (curves, mostly, plus circles and a few lines) for a set of forms and jigs for building a guitar body. Any file manipulation in AutoCAD I pay $85/hr for, while sketch up time (mine) is free…

There is a difference between 2d and 3d DWG/DXF Exports. The 3d Export includes Arcs, Circles etc as those equivalent CAD things - i.e. smooth ‘curves’ without segmentation. But the Export as 2d always makes everything out of Lines - and irrespective of the SKP’s Circle’s segment count in the 2d C…

[image] TIG: irrespective of the SKP’s Circle’s segment count in the 2d CAD version it has 24s… on my mac a 64s SU arc exports as 64 edges with dxf 2D export? @bevanfrost do you use the Pro version? john

For the next 3 weeks. I intend to do all my drafting (3 more instrument models) and exporting before then

@john_drivenupthewall You are correct. :blush: Brain-fart… The Circle’s increased segmentation on export is retained in the 2d CAD file as more/shorter Lines. What I was thinking of was that the import of CAD data always converts CAD-Circles into SketchUp Circles with 24 segments etc…

Thanks for all the help, 3d exportation has solved my problem. This community makes this tool easy to use. Thanks so much. Bevan

Use the Export as a 3d Model option and it will export true circles and arcs.
