rs.GetLine(1, None, ‘First point’, ‘Second point’) does not stick to the tab direction lock, when selecting the second point. This is in contrast to other Rhino commands, e.g. !_Line.
Is there a way to make it stick to the tabbed direction or is this a bug?
I’m not quite sure I understand this. If I run the script you suggest and hit the Tab key after picking the first point. The direction is constrained. Are you not seeing this?
