I have this problem when exporting a DWG from Rhinoceros3D and importing it into Sketchup. Despite ensuring that everything is straight and square in my DWG, upon importing into Sketchup some of the elements become totally distorted and morphed. I have no idea how to fix this because I’ve flattened the drawing; imported and exported from AutoCAD to try to resolve the issue, used plugins to align the axis and so far nothing has worked. I’m not sure what’s happening, but I’d like to just have the drawing straight and square when I import it.
