1. Line: Not sure what I did, but now all my attempts to draw line is failing.
I'm not getting the usual square and circle symbol for a new line (Line 037).
2. Dimension: Don't see the dimension I created for "Line".
3. Hatch: I created outer perimeter and inner perimeter to create hatch and then delete the inner perimeter by exploding at the end (something you see in AutoCAD).
Attached is the freecad file.
Thanks a lot!
