Steps To ReproduceOpen the attached model (Tube.FCStd)
Open the drawing page and set the Front projection direction to X0, Y-1, Z0.000000
FreeCAD hangs while generating the view and has an excessive number of vertices when complete.

Set the projection direction to X0, Y-1, Z0.000001
The view is now missing lines.

Set the projection direction to X0, Y-1, Z0.000100
The view is now almost perfect.
