Hi George, there currently isn't any way to draw directly on a surface, you will have to draw in one of the views and then rotate it.

I do want to make this type of drawing work eventually, but I don't think that it will be ready for the V1 release, though.

Thanks Michael for the quick response.

Believe it or not , I try to construct 3d road interchange model in Moi using elevations and alignments plans. I think I am on good way.
