![]() Many parametric CAD applications ask the user to start with a two-dimensional sketch, precisely drawn, and then the sketch is extruded or expanded into a three-dimensional shape. In parametric CAD programs, the software tracks the changes and allows the user to change earlier steps, and then the software reapplies the layer transformations or actions. Like building a model out of wood, where you want to change shapes at the bottom of the model, the user has to remove all of the wood structures constructed on top of this base. In many of these direct manipulation programs, once a step is complete, combining two items and then using a third object to model a hole in the combination, the user is unable to go back to the first step and make a change. Some CAD programs start with standard 3d shapes cubes, cones, pyramids, spheres, and more, and the user manipulates there objects by combining them to create the model. Why parametric CAD, and what is it? A simple definition of computer-aided design programs that use computer software to create 3d dimensional objects and plans divides these programs into two types. This series will teach FreeCAD to anyone interested in learning how to prepare 3d models from scratch for fun or profit. And, last but not least, the forum contains a lot of replies to questions asked by other newcomers.While I have covered FreeCAD in the past, I have not created a series of videos that teach regular people about parametric (more on this in a minute) computer-aided design (CAD) from the very first step to advance techniques. On external sites like Youtube, you will also find a load of video tutorials created by users. ![]() The User hub section of this wiki lists all pages aimed at end users. The Manual:Introduction is a general, complete user-oriented guide to FreeCAD. The Tutorials section contains many specialized tutorial pages to help you getting started with the different workbenches. You might want to start with the Getting started page. There is a lot of documentation spread in different places, both on and outside the FreeCAD website. Is there documentation for newcomers? How can I learn to use FreeCAD?Ī. To summarize, you are free to do (almost) anything you want with it. FreeCAD is open-source software, and is free not only to use, for yourself or for doing commercial work, but also to distribute, modify, or even use in a closed-source application. Is FreeCAD really free? Even for commercial use?Ī. For further details about installation, refer to the installing page for your operating system (Windows, Linux or Mac). On Ubuntu, the FreeCAD team also maintains its own PPA repositories. If you are on Debian, Fedora or Ubuntu and some other distributions, FreeCAD is already included in the standard software repositories and you can simply install it with the software manager. If you are on Windows or Mac OS, the simplest way is to head to the Download page, where you'll find several ready-to-install packages. What is the easiest way to install FreeCAD on my system?Ī. The only prerequisite is that your graphics card or chipset must support OpenGL, preferably no older than v2.0. If your computer is running a current operating system, chances are FreeCAD will run. In contrast to most 3D CAD software, FreeCAD can run smoothly on the most modest computers - it's been known to run on Pentium IV and Intel Core2 Solo CPUs. What are the prerequisites for running FreeCAD?Ī.
