Subject: [PATCH] Extending
 https://github.com/IfcOpenShell/IfcOpenShell/commit/3ebb046619e43a1f42087e95fb9be1959cbfe0a4:
 Force UI redraw to flush pending Blender operations, as Blender was crashing
 during bulk printing.  Not 100% this fixed everything, as there are a few
 crashes that spring up still, but is better.
