I have lately gotten issues with the sketcher, it have become hard/impossible to select vertices, edges and constraints.
Are building from source. Is this an known issue?
Which system do you use? There were issues when the grid in sketcher was turned on, but they have been fixed in master.
Geez! How hard can it be?About the development of the Part Design module/workbench. PLEASE DO NOT POST HELP REQUESTS HERE!
