FreeCAD

Bravo les créateurs de FREECAD

Commentaires : Pour certaine entreprise le cout financier et importants c'est bien qu'il y aient des logiciels libres

Avantages :

Tous les ateliers sont faciles à prendre en mains

Inconvénients :

Quelques ateliers sont à améliorer par la communautée

Si vous prenez le temps d'apprendre vous serez extrêmement satisfait !

Commentaires : J'ai peut etre passé une semaine à comprendre comment réaliser proprement mes 3D. Je pense ne pas être venu à bout de toutes les fonctionnalités, mais pour ce qui m'est utile, je peux réaliser assez rapidement et facilement ce que je veux maintenant, et gratuitement ! Je l'aime beaucoup et le recommande.

Avantages :

Il est complet, gratuit et une communauté permet d'avoir le support nécessaire aux question qu'on peut se poser. Ce n'est pas Soliworks non plus, mais le rapport qualité prix est sans correspondance.

Inconvénients :

La prise en main au début est très lourde. Et des fois, il y a des problèmes de conceptions qui ne sont pas clairement expliqués. Il faut chercher pour savoir ce qui en est à l'origine. Enfin, si vous placer un chanfrein, et que vous modifiez des calcul précédent, il se peut que le chanfrein disparassi et aille se placer ailleurs... Alors oui je comprends que les calculs "font que"... mais ça aurait été chouette qu'il le comprennen seul ou au pire, propose la vérification des chanfrein. Car quand il ne se montrent pas, on ne peut pas les sélectionner et du coup on ne peut pas les enlever.

CAD software provides a good opportunity for rendering different models of houses and buildings.

Avantages :

In comparison with other AutoCad softwares,it is one of the different version software. We can make 3 D drawing through this software at different angles of projection which is is indeed the most fantastic feature. This software is used by everyone whether students or professionals but proved to be helpful to everyone.

Inconvénients :

Sometimes when we are updating modules, at that time some of the modules are not updated. So we feel that they will update in next versions of software. The learning curve of this software is quite difficult for the new users. For this sometimes some users have to take CAD classes in order to have good command on the usage of this particular software.

Good free tool, but not at the level of the bests. Ideal for small companies and simple project

Commentaires : I usually work with non-very complicated designs and I am used to created them from the typical 2D sketches, but I can highlight some features I like and the ones that helped me more: it is possible to import an STL file (a mesh) and convert it to a solid, which you can work with later (very useful if you want to modify any design found on the Internet); there are many plugins that help to improve FreeCAD, i.e. I use KiCadStepUp tool to import a KiCad PCB easily and be able to see the entire design with it's electronic part, which includes every electronic component.

Avantages :

This is a good software for 3D design. It is for free and there is a great community that can give support to you, with a lot of tutorials in Youtube. Since I am a contributor of other free and open software like KiCad, it's great to have a 3D design tool like FreeCAD. Also it has many integrated tools to work with 3D and 2D designs, you can review models, import many file formats and convert some meshes like STL to a solid.

Inconvénients :

FreeCAD has some bugs and some of the functionality is not very intuitive. From my point of view, the bugs are its worst disadvantage and some of them are the next ones: the third-party components are sometimes not imported properly, that could be because the design is broken, but I experimented it several times, so I suppose there is some bug or incompatibility; the mesh-to-solid conversion sometimes fails; when you are designing a 3D part that has some features like chamfers or edge roundings, if you changes the previous steps and it makes the number of faces varies, the part will break down, so its important to keep this bug in mind and do those conflictive features in the last steps of the part design.

Great open source program

Avantages :

-Open source -Easy to use -Many different workbenches -Many file formats supported -Preferred to Solidworks

Inconvénients :

-Near no customer service and sometimes sub-par tutorials -Getting the right install location can be difficult -Some operations fail unexpectedly -Hard to use with sheet metal fabricated parts
