Hey guys. I’m having a problem with my offset tool I’ve never seen before. When i create closed winding objects (a street in this situation) & try to offset, the lines & arcs cross each other. The command works fine if I offset outside the object. It only happens when I offset inside. I’m designing a 40’ wide street with 2’ curb & gutter. I’m using sketchup pro 2018 & have been using sketchup for 15 years. Never came across this ever. Thanks
