I use FreeCad 0.19 on Windows 10 and Windows 7.
Both PC Freecad crashed when I use the tool Countersunk from the addon Fasteners.
I create a cube with a hole (I tried Part design and Part environment)
Select the environment Fasteners
Select the hole profile. The Countersunk icon become activated.
Click the Countersunk icon (the hole profile become deselected)
I select one edge on the panel. I change the diameter of the hole. I press Ok icon. Nothing happened.
I select the profile on the model and FreeCad crashes.
This happened on both my PC.
Can you help me?
