That's a problem with the cad kernel. It seems that the resulting shape has an error but fixing it doesn't solve this error here. |
|
|
Maybe we should first try this with the latest OCC release. If it still doesn't work it should be reported as bug to the OCC forum. |
|
|
Testing on OCC 6.5.2 and FreedCAD SVN 5391 shows the bug has been fixed if I follow the issue correctly. Images attached showing results. |

How do I download a version of FreeCAD which includes the fixes described by cstrachan1 (0001548)? |
|
|
I am unaware of a packaged version that includes both the OCC library and FreeCAD at the latest revisions. You can download the OCC library from the Open Cascade project and compile, this should be relatively straightforward on Ubuntu 10.04 and should avoid the need to patch for the latest gcc changes. If you decide to do this and run configure without any option, the OCC libraries will be installed in a non standard location that will allow you to have both the latest and packaged versions of the libraries on your system at the same time. You will need to tell FreeCad where the library is though, the simplest way is to start through the command line with export LD_LIBRARY_PATH=/usr/local/lib before the FreeCAD command. The latest version of FreeCAD is available through SVN at the FreeCAD download page. There are full instructions on compiling FreeCAD under Ubuntu on the site. |

fester2251 is already using the PPA version of FreeCAD, which is trailing the development source by only 24-48 hours, so no need to compile from source. I have FreeCAD installed from PPA on Ubuntu 11.10, with Open CASCADE 6.5.0 from the Ubuntu repositories, and I have no errors. Ubuntu 10.04 has OCC 6.3 I believe. There is an independant project, Open CASCADE Community Edition (OCE for short) which provides its libraries through a PPA. Even though the number doesn't match (OCE is at 0.6), I believe their development is based on OCC 6.5. https://launchpad.net/~hmeyer/+archive/3d I have no idea if there's something to do to tell FreeCAD to use OCE instead of OCC. |

Just a commentary; I just downloaded rev 5047, the problem remains. >fester2251 is already using the PPA version of FreeCAD, which is trailing the >development source by only 24-48 hours, so no need to compile from source. cstrachan1 (0001548) left his commentary on 01-07, that was in excess of 192 hours ago. |

fester2251, The problem is not with FreeCAD, it is with the Open CASCADE 6.3 libraries you are using. That's what we've been telling you. Either compile OCC 6.5 from the source, replace it with OCE 0.6 from the PPA, or upgrade your Ubuntu to a version with Open CASCADE 6.5, otherwise your problem will remain, no matter which version of FreeCAD you have. FreeCAD does not have ANY control over the Open CASCADE libraries. |

Since this is clearly an OCC issue and we from FreeCAD-side can nothing do on it I will close this bug report. Fixed with OCC 6.5. |
