FreeCAD

Avantages

Tous les ateliers sont faciles à prendre en mains

Inconvénients

Quelques ateliers sont à améliorer par la communautée

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.

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.

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

Pourquoi passer à FreeCAD

Avantages

I use freecad to design high power rockets. I also teach it to our STEAM club students at our local library. It is a great exposure for them to using a parametric 3D modeler and with addons provides a simple way to develop rocket components (e.g., nosecone, fin-can, etc.)

Inconvénients

Freecad has one major bug that needs to be fixed before I can generally recommend it. That is the infamous "topological naming problem". This issue is not unique to Freecad. Most parametric modelers have to deal with this issue in some way. In a nutshell, when you add, remove or slice sections of a model that has other sketches extruded from it, then all the surfaces get renamed. This causes the point of attachment of new sketches to be changed, so an extrusion may suddenly come out from the side instead of the top of the model. The Freecad development team is working on this issue, but as an open-source project developed primarily by volunteers progress is slow. Development work on this problem has recently picked up though. Once this is solved, I would not hesitate to recommend it to anyone need a parametric 3d modeler.

Avantages

Price (free), functionality: solid modeling (not just a collection of lines, arc and circles) , features, (eventual) ease of use, ability to create .stl files for 3D printer. The software is parametric meaning you can adjust dimensions and update the model, ability to create assemblies.

Inconvénients

Steep learning curve but thankfully with YouTube... I haven't looked for awhile but the documentation was lacking when I first got into it. I haven't had to use the forum for help so I can't speak to that but in searching the forum it seems to be very active with volunteers answering questions.

Avantages

Can create any part you can imagine, exports to 3d printing friendly formats, sketching and part design workbenches are relatively easy to learn.

Inconvénients

There are some software quirks on of them is you can not attach sketch to surface and modify the body that the sketch is attached it will mess up the part, while there are ways around that I wish they would fix it in the next iteration of the software. Also if downloading official release the UI is outdated.

Pourquoi passer à FreeCAD

Avantages

Excellent tool for designing structures in detail, elaborating analysis parameters for deformation and strength calculations. And it's still possible to do it on less powerful machines, so to speak.

Inconvénients

Transferring the drawing to paper with a level of detail is already a little more difficult, it has a lot of loss, also if you need to make a large and detailed structure, only with FreeCAD it is very complicated, for that you would need some other tools, making a more complex job.

Avantages

For new users in 3d parts for mechanical design it is a good tool. It is an open source project and has a large community that helps fix bugs, implement cool new features, or work on the documentation.

Inconvénients

At the moment I find it limited compared to other software of the same type. But this should improve in no time.

Avantages

That it is free. In theory it is easy to use.

Inconvénients

Snap function work very bad, dimensioning won't work and things go into error what ever you try to do.

Avantages

I think some Pros could be: supports the creation of 3D parametric components, which is essential for designing complex objects and assemblies; is available on multiple platforms; is designed to be modular and extensible

Inconvénients

Some Cons: has a learning curve, especially for users new to parametric 3D modeling. The interface may not be as intuitive for beginners; some users have reported stability issues, such as occasional crashes; some specific workbenches in FreeCAD may not be as actively developed or as feature-rich as others

Avantages

the strength of the program is the free license. With this premise everything is given away. It also works well and interesting projects can also be created

Inconvénients

it is not comparable to high-end programs, on a professional level it is not yet usable

Avantages

The software interface is simple and easy to use. Very convenient for quick CAD design with a very quick learning curve. Free and powerful tool.

Inconvénients

It is clear that this software is inferior compared to other more fancy paid options but it gets the job done. The graphs are simple and not that high quality. It may not be the best option for more complex projects.

Avantages

First it is free and you can do almost everything in it that you can do in Autocad. Its a got a nice supportive community to clear doubts and there are plethora of tutorials.

Inconvénients

As its not an industry standard you will have to adapt to other software over time and if you are going to work professionally then also you will have to switch to an other software.

Avantages

A different version of software compared to other softwares such as AutoCAD and its very nice 3D drawing in different angles of projections. I am blessed to see my great work in this software.

Inconvénients

some modules isn't it updated and It seems they are going to update in next versions of software updates.

Avantages

Coming from a paid win software, this was the first linux alternative I tried. There was no big deal in getting familiar to the tool layout. Great simulation tools, similar workflow to other CAD.

Inconvénients

Nothing to say here. It is a very capable software that I use.

Avantages

It is an adequate program for those who just need to open the part and look at it, take a few dimensions and take the old versions on top of each other and examine the differences.

Inconvénients

The interface must be seriously reviewed.

Avantages

can be oriented by user script and easy to implement automatic CAD generation.

Inconvénients

poor and very complicated user interface. 3D surface generation can not react that you desire.

Avantages

As an architect I always looking for new options to see how my designs come to life, and I found it a free option with FreeCAD, because I can create my model in the software and see how buildings, houses, park and other types of construction come to life, all this with high precision and detail.

Inconvénients

Is not as powerful as a private software so the process of rendering are always the same, and the results are always so similar.

Avantages

This is the best software for working with CAD programs since it is available on all operating systems (even Linux, which is hard to come by). I love all the features it has for a completely free and open environment.

Inconvénients

The controls can be frustrating at times. It's also a bit lacking in the amount of features. (either that, or I cannot find them!)

Avantages

I had never think do this in a software but FreeCAD is so complete, because after to made my model I can saw how my instruments and robot come to life it is wonderful and very useful to explain processes and practice with students.

Inconvénients

It is very difficult to do this it takes me a lot of time to create my first Robot Simulation because there are so many details to tu put on it, but the results is amazing.

Avantages

This software is excellent for me, because it allows to skecth my designs in two dimensions before modelling and rendering, I can build and manage my objects in two dimensions which is better for me, because I can see my models pretty clear.

Inconvénients

For me it is very difficult to do the transition from 2D to 3D because there are a lots of options that I do no manage for work in three dimensions.

Avantages

Does what you expect from a free tool standpoint.

Inconvénients

Just covers the basics, could use some easier tools.

Avantages

It is free and comes with great tools for 2D and 3D drawing. Another feature that is great is that is not completely restricted, it can be customized and is open source.

Inconvénients

You need to spend a lot of time getting to know the software to use it or have lots of experience with cad programs. It can crash a lot.

Avantages

I started using this software for my master thesis a year ago. With no prior knowledge of 3D designing, it was a big challenge to learn it over a matter of few days. Surprisingly FreeCAD was very helpful because of its simplicity and user friendly features. I highly recommend this software for someone who is beginning in the field

Inconvénients

It does not seem to have some high level features which make the end product look very professional and chic. But that also comes as a consequence of user friendliness and the need to not crowd the software with complicated stuff
