Summary0004207: Loft between two simple sketches freezes the software
DescriptionWhen trying to use additive loft between two simple sketches in an otherwise empty file, the loft does not appear on screen. Most menu buttons seem to respond at first, but as soon as you try to interact with the view, ie by changing the view angle, the whole software freezes.
At this point the only way out is to try and close the program, which results in a windows popup about the program not responding, wait/force close.

Notably, If I save the file after using the loft button, but before trying to change anything to the view, and reopen the file after the crash, the loft appears to have been performed normally, and the software seems responsive.
Steps To Reproduce1. Create a new file
2. Go to part design workbench
3. Draw a simple sketch on XY plane, ie a rectangle
4. Draw another simple sketch either on a different plane, or on a parrallel plane
5. select one sketch
6. click additive loft
7. Click add section
8. click on the second sketch
Additional InformationThe bug appears to be connected to the graphical representation, rather than the way loft actually works.

I'm running freecad on a HP envy 360 laptop, with a AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx CPU (integrated GPU).

@idobox : according our guidelines (big yellow banner), could you please first open a topic in our forum so that potential bug can be confirmed and identified by community ? Think about providing an example file to reproduce there. ;) Thx

I've noticed the bug in 0.18.4 and found this bug-ticket, downloaded the 0.19pre and can say: Yes it's fixed and the loft tool works again.
