translate and rotate from text file. #125

Closed bentleyeglin closed 4 months ago

bentleyeglin commented 4 months ago

I have a .g that was built from STL. It has one region and the path is all/r.stl/s.stl s.stl is not a solid, but rather a BOT Bag of Triangles. I need to be able to translate and rotate this region from a text file: mged model.g < input.txt EDIT I am able to translate and now rotate in my text file I have to translate: e s.stl sed s.stl keypoint 0 0 0 tra 0 0 -1000 accept push s.stl

to rotate the command is rot. I'm rusty.

I was going to say, you have to draw/e the object before you can sed it. After doing that, either rot or orot should work.

Also just a note -- it's only useful to set a keypoint for rotations. It tells it which point to rotate about. For translations it doesn't hurt, it just doesn't matter though either.
