Summary0031479: Modeling Algorithms - exception on geometry transformation of triangulation-only shapes (without geometry surface)
DescriptionThe uploaded file just with shape with triangles, without geometry surface.

It works when apply move and rotate operation. it's break with scale or mirror.

Neither BRepBuilderAPI_Transform or BRepBuilderAPI_GTransform works with scale or mirror transform.
Steps To Reproduce
test de_mesh obj_read prism 1
XGetOneShape s D
tscale s 0 0 0 10


Result:
An exception was caught 000001F39E054090 : OSD_Exception_ACCESS_VIOLATION: ACCESS VIOLATION at address 
0x0000000000000000 during 'READ' operation
