Exported .dwg from sketchup has square edges on round surfaces

[Bitseeder]

Hi guys,

Having a issue with my .DWG imports from SketchUp PRO 8.
When i open them in AutoCAD 2012, all the round/curved faces are segmented and makes my annotation sheets look crap.

Have tried exporting my Sketchup model as a .FBX and a .3DS model, importing into Autocad, exploding the mesh, regioning the resulting 3dfaces then using SURFSCULPT to create a solid.

would Really love to know how to make these surfaces smooth.

attached is a PDF to show you what im talking about.

Any help would be greatly appreciated.

The problem is that SU really does not do curved surfaces. It just simulates them. Don't get me wrong I love SU but that assembly looks like it could be done in Acad just as easily and with true curved surfaces.

Give that drawing a try with AutoDesk 123D. It's like an Inventor for home users. It can export to several formats including dwg.

thanks mate,

I use SU for my 3d for the speed i can do these types of things. I do use AutoCAD for more crucial components, But a pipe run with multiple axis and angles just eats up to much time.

what i have done though is configure SU circle to draw 100 edges instead of the 24 that was in the previous pdf. not perfect but does look a lot better

That does look better. What did you render that in? I like SU for it's speed as well. When I do cuvred items I usually smooth out the curved items or hide the lines.
Thanks for sharing and welcome to CADTutor

It isn't rendered, just assigned a materiel in ACAD.

yeah thanks! really enjoying it.

this is also my problem. i hope there is a way to import sketchup smooth surfaces into acad. or make those edges look smooth in autocad.

Nope not possible, sorry. SU only simulates curved surfaces. One of it's few flaws IMHO.
