Hello all, Been looking for this information for quite some time. Is there any information available on bounding box colours? I understand well the green > yellow > orange > red and the thickness of the box, but nowhere can I find what the Cyan and Blue colors mean. Any pointers welcome, The biggest confusion I currently have is this: Some objects imported from sketchup, after being transformed with Break > Solids into Surface, will turn Cyan after mesh consolidation, some will turn green. I am really trying to understand what is going on and what are the best practices when seeing these colors as boxes. I am fully aware of these threads before anyone link them ;-) http://forums.cast-soft.com/index.php?threads/geometry-optimization-and-file-efficiency.283/ Thanks!
