FreeCAD

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

Vorteile:

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.

Nachteile:

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

Kommentare: 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.

Vorteile:

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.

Nachteile:

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

Vorteile:

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

Nachteile:

-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

FreeCad - Great hobbiest cad with a caveat

Kommentare: Freecad provides an easy method to develop rocket components. This allows students the opportunity to use a parametric 3d modeler to model 3d components that they can then print on a 3d printer and finally actually see their rockets "Blast Off!' It works well for our use at the library and could be useful for many hobbiest projects. It is probably not quite ready for most production work, but that could change soon one the topological naming issue is resolved.

Vorteile:

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.)

Nachteile:

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.

Excellent product for free

Kommentare: Love it. I used Pro/ENGINEER in the early 90's and it was such a wonderful leap over AutoCAD but hugely expensive. I used my outdated copy of AutoCAD for years until I discovered FreeCAD 5 or 6 years ago. Initially it was a steep learning curve but with the abundance of videos on YouTube and perseverance I am now quite adept at using it. I have designed/built a semi-automatic machine for my production and have several 3D printed tools used in that machine. FreeCAD has been a Godsend for developing and evaluating my ideas and I would definitely recommend it if you are a small business with minimal or no budget for expensive CAD software.

Vorteile:

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.

Nachteile:

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.
