I have imported a dxf onto mechanical layers, and want to use this to create the pads for a component footprint.
My approach is to select the whole outline of the would-be-pad on the mechanical layer, use "Tools -> Convert -> Create region from selected primitives", change the region's layer to the top layer, and then place a pad inside the region to assign the designator.
When I click "Tools -> Convert -> Create region from selected primitives" I get the error message:
"Could not find closed shape using primitives centerline due to the following error: Multiple paths found from location: (-0.15, 0.15) Would you like to try finding closed shape using primitives external edges instead?"
I have checked the position of (-0.15, 0.15) and it is a point where an arc meets a line. There appears to be no overlap and no duplicates at this point.
I am using Altium Designer v15.1.
