I would like to identify if a much simpler program exists... given a red/green render like L3Lab mytest6 can produce and a way to tell which quad/tri goes with which render, let me point at a quad/tri and just reverse the order of the vertices (...)

I use LDAO in combination with L3Lab. - Ensure your dat file has a "0 BFC CERTIFY CW" - Set the "stop at cursor" option in the LDAO editor. - Set the mytest6 and autofresh options L3Lab (and leave the BFC option on) - Step through the file in (...)

| | | | | | (...) Thanks... I am having trouble with these instructions, maybe I'm not running the right versions of things? I have LDAO 2.1.8 and L3Lab 1.2. I'm not sure what the autofresh option is... when I launch LDAO editor on my part, I set the viewer to (...) (22 years ago, 13-Sep-02, to lugnet.cad.dev)

| | | | (...) What would be especially good is if there was an option to test and flip adjacent polygons. Once the winding of one polygon is known, adjacent polygons can be automatically wound correctly. So you click one red polygon, and all the polygons (...) (22 years ago, 12-Sep-02, to lugnet.cad.dev)

In fact, there is nothing which prevents a single polygon face from being partly on the outside and partly on the inside. You can't automagically (...) (22 years ago, 12-Sep-02, to lugnet.cad.dev)

| | | | | | (...) Right. There are definitely situations in ldraw parts that won't fit the nice all-polygons-in-a-mesh model. That's why I said that auto-rewind should be an 'option'. Meaning, the user can turn it off. Although for a part to be BFC compliant, (...) (22 years ago, 12-Sep-02, to lugnet.cad.dev)
