| Summary | 0001710: Loft and sweep from 4-sided polygon to a circle fails (in certain orientation of the polygon) | ||||
| Description | In certain case the loft between a circle and a 4-sided polygon fails. See Steps To Reproduce section for details. | ||||
| Steps To Reproduce | 1. On a new document, select draft workbench. 2. Draw a circle and a polygon centered at the origin and oriented along x axis. Set polygon's number of sides to 4 (the polygon should look like a rhomb). 3. Set radii: R of polygon = 15 mm, R of circle = 150 mm. 4. Raise the circle along Z axis to 100 mm. 5. Swicth to Part workbench and create a Loft between the circle and the polygon. The loft fails with an error message: "BRepFill_CompatibleWires::SameNumberByPolarMethod failed" or sometimes "ACCESS VIOLATION at address 0xFEFD008 during 'READ' operation". FreeCAD does not crash, but loft is not created. OR Open the attached file where a circle and a polygon are already prepared. Make a loft between them - it fails. | ||||
| Additional Information | Sizes are important (e.g. Loft does not fail if the circle is R=50 mm). Orientation is important as well: change the orientation of the polygon to something other than 0 degrees - and the loft is there! Same goes for number of sides: 3 or 5 is OK. -----copied from About: OS: Windows Word size: 32-bit Version: 0.14.3700 (Git) Branch: releases/FreeCAD-0-14 Hash: 32f5aae0a64333ec8d5d160dbc46e690510c8fe1 Python version: 2.6.2 Qt version: 4.5.2 Coin version: 3.1.0 SoQt version: 1.4.1 OCC version: 6.5.1 | ||||

1. I can't reproce the problem OS: Debian GNU/Linux 7.6 (wheezy) Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.15.4004 (Git) Branch: testing Hash: 91380923beea61d49b35df2107368e2008893ddf Python version: 2.7.3 Qt version: 4.8.2 Coin version: 4.0.0a SoQt version: 1.6.0a OCC version: 6.7.3.dev-0304f71 2. There are known problems in the SameNumberByPolar method (http://tracker.dev.opencascade.org/view.php?id=24997) But this happens inside our geometry kernel, and there is little we can do about it. 3. Your version of OCC is quite old. Is there any reason why you did not install the 64-bit version of FreeCAD, that ships with a newer version of OCC? |

I downloaded 32 version of FreeCAD simply because at that moment I didn't know that 64-bit version is superior. I just followed what Microsoft suggests when installing their Office. I know it's irrelevant, but I was downloading FreeCAD for the first time ever, and of course I didn't bother reading the forum or googling. I'll upgrade and verify. |

64-bit FreeCAD - it works. i.e., no bug. I think the bug can be considered resolved, except I would like a note to be put on download page that 64-bit ver is superior.
