Hi Michael,

When a curve is formed from 'joined-up' edges in Sketchup the rendering seems fine. Although there is a lower limit on size it seems quite small. But generally it will do curves and rounded things fine.

I think the styles are built up from a series of different sized images. It may be that using the Sketchup Style-builder you can extend a style to add an extra small size image to the series of images to cope with small disconnected edges being used to describe curves.

Is there any way to force the geometry on export/import to mimic how Sketchup is representing the curves when they're created in Sketchup natively?
