Yeah, I have seen that part, it is kind of awkward but possible.

However, that is not what I was talking about, I was talking about drawing a line, with the start point of the line tracked away perpendicular from an existing point. Just the start point, not the whole line perpendicular.

Here is an example:




This is one part of the steps I happened to use above when showing how to do the polyline drawing of the box in the 3D view in MoI. When I tried to repeat the same sequence in SketchUp with inferences, I was unable to draw this line while staying inside the line drawing tool only.
