I have a rigid-flex board where I want to add dimensions to the individual sections, for instance length of FR4 section or flex section. The problem is that Draftsman only seems to accept the outer contour of the complete PCB as valid point to snap the measurements to. I get an orange in the corners or the complete side highlighted as the mouse pointer hovers over it. A T-shaped intersection between corners seems to be impossible to snap to. Tried to add lines that goes outside, inside or with connection to the PCB outline, but none of them seems to be accepted by Draftsman after updating the board. The line is there, but it cannot be selected.
It is also not possible to add a measurement and then to move it manually to the position I want.
We are on subscription so I just filed a case to the support, but any thoughts or ideas for workarounds?
