J'envoie le fichier à Michael au cas ou il aurait un mac sous la main mais bon en voyage c'est rien de moins sûr!

Et sinon pour d'autre fichiers "normaux" ça marche ou ce n'est que pour ces fichiaux "spéciaux" venant de ce demandeur ?

J'ai installé la dernière version de Moi3D sur une partition PC avec Parallels. Ça plante pareil à 6%, j'ai une alerte Mémoire insuffisante".
Comme dirait ma voisine de 76 ans, "Qu'est-ce qu'il a dans le cul, celui-là ?".
Je ne suis pas un grand maître de Parallels, il y a peut-être des réglages à faire même si celui-ci me recommande de ne pas dépasser 4 Go d'allocation mémoire.

Je vais laisser passer le WE, je verrai plus tard. Ceci dit, ce n'est pas très rassurant.
Généralement, j'arrive à exporter sans difficulté. S'il y a trop de pièces, j'y vais pièce par pièce mais là, c'est incompréhensible.

Tout s'explique! Enfin presque! :)

Hi Pilou, this model is taking an unusual amount of memory to process, one of the only differences between Mac and Windows versions is the Mac version maxes out of memory slightly earlier than the Windows one, the Mac version can go up to around 3.1 GB while the Windows version can get to around 3.6 GB before running out of 32-bit space.

Anyway that's why there is a difference between the 2. But the main problem is that this model seems to have some hidden complexity to it which is causing excessive memory consumption which is happening on both Mac and Windows as well.

The problem seems to be in some of the small fillet surfaces in the upper part, see the attached screenshot that shows which ones seem to be the most problematic.

Those surfaces have something unusual about them, I'm not entirely certain what it is exactly yet, I'll try to investigate a little more. I suspect the trim curves may have a very high complexity (like many thousands of control points) in them.

Anyway it is a few of those little fillet pieces in the upper part that is not going very well currently. I may not be able to really tell exactly what is the specific problem with those surfaces until I return home from vacation.

Thanks, - Michael

Cela va donc être un petit peu problématique si le fichier de départ a ce genre de mauvaise modélisation!

Hi Pilou, the problem was in those small fillet pieces that I sent a screenshot of earlier, there is some hidden complexity in those little pieces that is causing the meshing to take a lot longer and also a lot more memory than it usually would.

I've attached an updated version of the model here which has those particular surfaces reconstructed, this version should behave much better.

When I return home from vacation I'll investigate this further to see if I can tune up anything automatically to improve the behavior on the original model.

- Michael

Devant l'impossibilité d'exporter certaines pièces, j'ai téléchargé Freecad. L'export s'est passé sans pb. Ouf !
Bon, c'est tout triangulé mais l'essentiel est d'avoir les pièces en polys.

Il est tjs rassurant d'avoir une solution de repli.
Je voulais utiliser Rhino mais ça ne marche plus en OS X 10.6...

Bonjour,

Ce genre de problème insoluble respire le virus. Ton ordinateur est-il plus lent qu'au 1er jour?
On se ramasse des spywares par dizaines sur le web. Passer un coup de adwcleaner, utilitaire gratuit.

J'en profite pour conseiller VirusKeeper, pas cher & français.
Il trouve tous les spywares & les virus, même ceux installés par Microsoft; et il est plus cool que tous les autres.
Vous ne regrettrez pas cet achat & cette tranquillité. Vous verrez votre ordinateur retrouver sa vitesse normal.

PS. Penser à défragmenter son disque, ça évite certains problèmes de fichiers trop découpés.
Mon PC qui prenait 3 ou 4 mn pour s'éteindre, avant VirusKeeper, & quelques spywares, le fait en 15 secondes.

EDITED: 31 Mar 2014 by BFM

Non, non cela vient juste du fait qu'il y a des zillions de minifacettes qui mettent en transe l'organisation de la mémoire Moi!

Donc un besoin énorme de RAM & de disque propre. J'ai eu tellement de problèmes liés à ces spywares & quelques virus, que le conseil vaut autant pour moi. En attendant le VirusKeeper français est très efficace... Le prix de la paix 24,90€; à tester absolument: http://www.viruskeeper.com/fr/
