![]() So, except in relatively unedited models we wouldn’t have circles to export anyway! Likewise, we would continue to see intersections happen along the polygon Edges, not at the true perimeter of the circle. We would still face the situation that some kinds of edits would force SketchUp to abandon the metadata identifying a sequence of Edges as coming from a circle. ![]() The smoothness of a circle couldn’t increase when we zoom in. Without this fundamental change, many of the things one would expect from circles would be impossible. Provided that the destination format supports real circles and curves, I can’t imagine any reason the 2D vector exporters and importers couldn’t be reworked to support real circles.īut a deeper issue is whether it would be practical to modify SketchUp so that it constantly recalculates the locus of a circle based on the mathematical formula for the circle vs based on concrete representation as a regular polygon. For consistency with what you see when exporting to a raster format, the programmers just pushed out the Edges and Faces. It seems more likely to me that the 2D export and import were originally conceived as image-oriented WYSIWYG, sort of like screen shots, even when the destination format is vector. The 3D math is a bit messier, but that is hardly enough to prevent true export. All 3D adds is the ability to have the circle arbitrarily tilted instead of restricted to a fixed drawing plane. Or are you telling me you don’t want this feature because SU is a 3D modelerĪnd you have some inherent objection to it being used for 2D?Ĭircles are planar regardless of whether they are drawn in a 2D environment or in a 3D environment. So, you know it is technically impossible for SU to represent a 2D curve?Īs that is all I am suggesting as a request?
