Canceling an extrusion by pulling lead to a crash for some holes specially
This video shows how to get around it.
Why does that happen in the first place ?
There was a second hole , used mirror to create its sketch, I had no problem with pulling it .
There is also mirroring issue even for a circle shape in the exact center it shows different measurements than the original side by small decimal and create strange line in the middle of the shape even with union it does not disappear.
I had no problem drawing the whole circle for fun but this miss measurement can cause an issue specially for small parts.
