I used to be able to export a 2D graphic as a dwg or a dxf to illustrator with the profile lines, the section cut lines, and the surface lines all separated on different layers for me. This saved me a huge amount of time adjusting line weights in my drawings, but since I updated SketchUp to 2023, it no longer separates my lines into different layers when I export. I do not know which settings were in place to give me this feature before. When I tried to help my classmates set up this feature, I could never figure out what the difference was between my SketchUp or illustrator settings and theirs. I have never used Sketchup Layout or Style builder. I do not use different line colors or the tags feature very often, and I was able to export the different layers before I even learned to start using these features.
When I open old dxf / dwg files I downloaded before the update, the separate layers still automatically appear in illustrator. So this had to be something that changed with sketchup when I updated. I’ve tried to attached a screenshots of the layers illustrator automatically makes for me when opening these older files.
Does anyone know how to get this feature back? Please, this would save me so much time.
