| Summary | 0000458: Problem fusing a cylinder with a torus (Probleme de fusion entre un cylindre et un tor) | ||||
| Description | When I do a fuse between a cylinder and a partial torus, 3 times out of 4 the fuse doesn't work and generates random shapes (Quand je fait un fusion entre cylindre et un tor partiel (pour modeliser un bar avec un coude), 3 fois sur 4 la fusion ne marche pas et genere des forme alleatoires.) | ||||
| Additional Information | See attached file, try to fuse the pieces (Je joind un fichier. Tous les elements ne forme qu'une piece Tester de les fusionner.) | ||||

Presque aucun des développeurs ne parle français. Il vaut mieux écrire en anglais, même avec une traduction automatique. (None of the devs speaks english. Better to write in english, even using an automatic translation) |
|
|
There are a couple of modeling problems in the attached file... Some pieces don't coincide, and we saw recently that the OCC kernel has some deficiencies when dealing with torus. I'm not sure we can do much here. The best way would be to remodel, extruding a circle along a profile, for example. |
|
|
That kind of modeling will always lead to problems, cause you can not position the parts that exactly. Soon there will be a feature in PartDesign which allow you to extrude a profile along a sketched path. That will solve your problem.. |

|
Soon? As in v0.13? :-D |

(english version below) Bonjour luciol44, En attendant que la fonction de balayage d'un profil sur une trajectoire soit disponible dans l'interface graphique de FreeCAD (ce dont parlait Jriegel), il est possible de réaliser cette fonction à l'aide d'un script Python. J'attache un fichier en exemple (rollbar_sweep.fcstd). Je te suggère de poster un message sur le forum francophone de FreeCAD : http://forum.freecadweb.org/viewforum.php?f=12 Où je pourrai t'expliquer au besoin ma procédure, ainsi que te donner mon script. Le script ne génère pas un balayage paramétrique, mais les esquisses utilisées le sont. --- Hello luciol44, While we wait for the sweep function of a profile through a sketched path to be added to FreeCAD's GUI (what Jriegel was talking about), it is already possible to do it with a Python script. I'm attaching an example file (rollbar_sweep.fcstd). I suggest you post to the French FreeCAD forum: http://forum.freecadweb.org/viewforum.php?f=12 Where I'll explain how to do it, and paste my script. The script itself does not generate a parametric sweep, but the sketches are parametric. |

Bonjour Normanac, J'ai telechargeé ton fichier et je n'arrive pas à l'ouvrir. Plantage de FreeCad. quel version de FreeCad as tu? Je suis sur la 0.11. Si non je suis quand même preneur pour ton script. ---- Hello Normanac, I downloaded your file and I can not open it. FreeCAD crash. What version of FreeCAD are you? I'm on 0.11. If not I'm still a buyer for your script. |

(english version below) Bonjour Luciol44, En même temps que mon précédent commentaire, je t'ai envoyé un courriel via l'interface de Sourceforge. Tu ne l'as pas reçu? Je te recommande de poster dans le forum franco (lien plus haut), puisqu'un rapport de bogue n'est pas vraiment le bon endroit pour discuter. Ou envoie-moi un courriel à mon pseudo @users.sourceforge.net. --- Hello Luciol44, When I wrote my comment I sent you an email as well. Did you receive it? I recommend you create a topic in the French forum (see link above) since a bug report page is not really the right place for discussion. Or send me an email to my username @users.sourceforge.net. |

J'ai créé un sujet de discussion dans le forum, rendez-vous là-bas: http://forum.freecadweb.org/viewtopic.php?f=12&t=1978 See above link to the topic I created on the French FreeCAD forum to continue the discussion. |

I can't tell if the parts are properly aligned. |
|
|
According to the occ guys this is indeed an alignment error. We need to have a look at the transformation precission used in freecad. Sebastian, I vaguely remember that you have done something in this regard already, was it the precission of the numbers written in the python interpreter? Does this fix this issue? Or was this only a experiment? |
|
|
In the past FreeCAD made it very easy to damage a file due misalignment by rounding in the QSpinboxes or by limiting the numbers of significant digits in th python console output. Werner a I addresses many of those issues before the 0.14 release. This ticket and the posted example files predates those improvements. Still, if have a object exactly placed you should not uses the property editor on the placement afterwards. As i don't know how luciol44 aligned the objects in this file, I can't tell if the problem was solved. Perhaps someone might try to align the pipe segments with Werner's align tool. |

I aligned the parts together but didn't use the Edit --> Alignment tool, rather the Draft Move tool with centre snap activated along with some edits to parts Placement. There was a 0.0001 degree difference between Torus_D and the Montant_D_2 cylinder's rotation. As well I had to remake a new torus to replace Torus_Haut_D as it wouldn't fuse no matter what. With revised placements, the Fusion succeeds. I only made one side of the rollbar, but the other side should be the same. Attached file Rear_Rollbar_normandc1.fcstd. So I guess this bug could be considered fixed. Checked on OS: Ubuntu 14.04.5 LTS Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.16.6707 (Git) Build type: None Branch: releases/FreeCAD-0-16 Hash: 5465bc47c95db45e0be85dc0e2872419efadce0f Python version: 2.7.6 Qt version: 4.8.6 Coin version: 4.0.0a OCC version: 6.8.0.oce-0.17 |

@wmayer FYI, the upstream bug that shoogen opened (http://tracker.dev.opencascade.org/view.php?id=25771) and mentioned in this ticket (0001936:0005743) is still open. Does that have any further implications on this bug? |
