I have opened a dxf drawing in SW and saved one block.
I need to fully define this block/sketch before I can make a feature from it.
There is no option to Select Chain.
Repair Sketch reports two points gap at each visible point.
Select Other on a tangent point reports the line, the arc, and 2 points.
I cannot see a gap between them in the magnified view or a zoom in view; the lines always join.
How can I achieve Full Definition?
