The main problem I faced when drawing or sculpting in vr, was to be sure that all the vertical lines where all really parallel lines. Most of the time I draw thinking that my drawing is fine, when I make a render in another software, I realize that nothing is right. Would it be possible to have a option that constraint the line we draw to one of the 3 axis of the local space of the current layer?
It would also be nice to have a planar constraint to draw shapes in a given XZ plan or one of the 3 others.
This feature would allow to make solid construction lines before to start drawing details on something.
