| Summary | 0004564: Excessive vertices generated for curved pocket on drawing projection which hangs application | ||||
| Description | Generating an XZ projection of the following part in the TechDraw WB results in an excessive number of vertices for the curved cut-out and blocks the UI thread (unresponsive). Original forum post: https://forum.freecadweb.org/viewtopic.php?f=3&t=55489&p=477314#p477264 | ||||
| Steps To Reproduce | Open 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.  | ||||

is there a connection with 4639? Overlapping lines not drawn?? |
|
|
The missing short lines seem to be a bug in OCCT. The number of vertices is appropriate for the projected BSpline. |
|
|
Can someone test this in the latest (OCC 7.6) ? |
