| Summary | 0001538: face-normal-flip when Part.Face() fed with internaly hold points | ||||
| Description | http://forum.freecadweb.org/viewtopic.php?f=22&t=6557 Hello, I hope to find out where the error with the flipping normals lies. It seems that Part.Face can not cope with certain float formats. I wrote a bug-demo script, below. And work around. OS: Ubuntu 13.10 Platform: 64-bit Version: 0.14.3544 (Git) Branch: master Hash: 94f10f5d95aae441dc18576a61b82740b676f299 Python version: 2.7.5+ Qt version: 4.8.4 Coin version: 4.0.0a SoQt version: 1.5.0 OCC version: 6.7.0 | ||||

I would consider this rather a design flaw in OCCT then a bug in the implementation. Hoever, since we neither address the problem in our python API nor in the user documentation, we should leave this ticket open IMHO. |

Upstream reports this should be fixed in OCCT 6.9 |

@normandc can you test this with OCC >= 6.9 ? |
|
|
@wmayer care to test this real quick ? |

Test script: p=(9.08, 8.62, 3.75, 1.87, 3.04, 9., 4.26, 1.37, -0.08, 9.08, 8.62, 3.75) v1=App.Vector(p[0:3]) v2=App.Vector(p[3:6]) v3=App.Vector(p[6:9]) v4=App.Vector(p[9:12]) pl=Part.makePolygon([v1,v2,v3,v4]) f=Part.Face(pl) pl.Orientation f.OuterWire.Orientation From occ 6.9 on both orientation are forward, in the past they were forward and reversed. |
