Importing curved DWG without losing curvature

clubber2k

Hi,

when I import DWG with curves sketchup turns them to bulky lines.
since I Can draw a nice curve with sketchup I guess there is a way to import the linework without curves turning into line segments?

not only is the curve lost but also the lines go out of place

what can I do?!

thanks

(still on SU8, don't want to got 2013 till i'm sure all plugins work and its bug free.)

see attached.

how it looks in CAD

how it looks in SU

SketchUp doesn't have real curves, AutoCAD does.

After you import the DWG go to the Entity Info panel (Window > Entity Info), select the circle or arc and increase the number of chords in Segments

I suspect the crossing lines are still in place. Unfortunately since the curve is now segmented the lines won't be intersecting as they should and have to be modified. If their location is not critical, perhaps those crossing edges should be redrawn to the SU vertices. It can be a bummer certainly.

Although it looks in this case the radial lines are part of the specific design

You have two issues - curves & lines meeting curves

In AutoCAD put the curves on a separate layer from the intersecting lines so you can turn off the intersecting lines in SU and increase the segment count to get smoother curves without the intersecting lines interfering

The other problems is that intersecting lines that meet curves in AutoCAD will either cross over the 'curve' in SketchUp or stop short of it, depending on which curve segment it meets. This will prevent you from making faces in SketchUp at those points.

SketchUp doesn't have a native Trim or Extend function like AutoCAD but you could try the plugin called 2D Tools to see if that helps you. But, whenever you can, extend the lines that intersect curves well beyond the curve in AutoCAD so you can trim them back in SketchUp.

Thanks to both of you!
can't believe I've been using su for so long and didn't notice the segment count.

anyway, I extended the lines and then used stray lines to select and delete the edges - guess thats the best it gets and thats not too bad

thanks again
