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

Claerly It's a simply and easy Viewer software, and you can read a lot of different cad file type.

Inconvénients

The possibility of creation are really like a CAD software are pretty bad.

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.

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

The most attractive feature is that it is free to use I am not very good at designing 3D projects but Free Cad seems to be for me a good platform to teach myself. There are other free design software out there but this one seems to have a lot of features for a free version I like the ease of use for a free open source program the menu items are well layed out

Inconvénients

There are some limited features but for free open source it is not bad. Python scripting I think takes a little patience getting used to but once you catch on it goes pretty smooth for a beginner.

Pourquoi passer à FreeCAD

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

As its name implies, the software is free. The active community has done a lot of great work in creating a fully-functional CAD program, with many industry-standard drafting tools and a plethora of optional add-ons.

Inconvénients

Unlike other modern free and open-source programs (for example, KiCad), the focus has not been on the user interface. As a result, many operations are awkward and perhaps even tedious to perform. Additionally, the native rendering capability isn't great; the displayed objects look like they're stuck in the 1980s

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

I was doing some quick prototyping of a new product and needed a CAD/drafting package. I started with the free version of FreeCAD and found it fully functional, with all the features and options that I needed. Once I learned the system upgrade was the logical choice.

Inconvénients

I found the environment difficult to learn and not intuitive, however, I am not experienced in this area, being a chemical engineer not a mechanical engineer which I am sure would have been much more comfortable. I needed to generate the drawing for some manifolds that we needed to import into Computational Fluid Dynamics.

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

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

The learning curve is much faster with the Polygonal system, since it is to draw in plane and to extrude. This is the main advantage of SketchUp. The use of the mouse to place and modify the polygons and to be able to give the exact measurements by means of a keyboard makes designing with this application incredibly intuitive.

Inconvénients

The problem comes when the pieces are complex and must also be exact. We all know that to place the centers of the circles in SketchUp we must make guides that we will later erase. This begins to diminish us quickly but when we want to place the polygons in different planes and with different inclinations the issue becomes impossible.

Avantages

...Its free??? Most CAD software costs an arm and a leg. I've played around with this software, and its really outstanding, obviously not as great as the high end software on the market, but who cares. Free beats spending hundreds of dollars and its a user supported community. You should really give this a shot, I had a blast trying to make thing to print on our school's 3D printer, and this gets you started.

Inconvénients

Obviously, you are not going to be able to have the support and training compared to high end products, but if you are willing to put some effort into teaching yourself how this work, then you are golden.
