|
reproduceable in DRAWEXE of OCCT 6.8.1-dev reported as http://tracker.dev.opencascade.org/view.php?id=25626 |
|
Still reproducible on OCCT 7.1 and upstream isn't on the roadmap. Requires bump. |
|
@adbdullah would you be interested in bumping the upstream ticket in the hopes that it may be added to the OCC roadmap ? |
|
Original attachment is missing, and the attached files in the OCCT bug tracker can't be downloaded. A loft between three ellipses rotated 90 degrees from each other appear fine in FC 0.18-dev with latest OCCT 7.3.0... |
|
What should be we do about this ticket then? |
|
Maybe the OCCT bug tracker requires to be registered to download. Since @abdullah has an account, we could ask him to upload the files here so we could check with FreeCAD compiled with latest OCCT. From what I understand of the posted DRAWEXE script (in the upstream bug, "Steps to reproduce"), it reads from brep files that are probably included in the zip archive. |
|
Files are attached. I will indicate that the FC project is monitoring this ticket and whether it will be assigned to a roadmap. |

@normandc @Kunda1 Bugnote #0081082 added by MSV (developer) 2018-11-14 10:12 Dear abdullah, OCC has no fonds to solve this bug in the nearest future without external investment or contribution. You are welcome to propose your fix if you can. |
|
Unfortunately it is a too big shoe for my feet. |
|
Thanks, abdullah. I imported the 3 brep files into FreeCAD and created a Part Loft. I'm attaching it for future reference. The issue indeed persists with OCC 7.3.0. Ellipses are rotated only a few degrees, I had tried 90 degrees between each ellipse and that worked. I also tried a sweep with a straight line from (0,0,0) to (0,0,20) as path; same issue. That's a bummer on OCC's reply... |
