#Freecad tutorials software
Helping people get the hang of this software is one of the ways I’m helping the project. I am firmly commited to using open source software for my own needs, so it’s one reason for me to stick with FreeCAD.

If you need more than that, then you could look at the free commercial software that’s available. It’s just that when the assembly module comes out, it will be a whole lot easier. But it’s doable, thousands of designers have been doing the same in AutoCAD for decades. It does not have a 3D relationship-based assembly module yet, so to assemble parts together it’s a little like in AutoCAD: you need to place your parts manually, and the assembly won’t be parametric. I’ll be honest, the software is nowhere complete yet, and some parts of it can get buggy. Well I guess it depends on whether it’s enough for what you’re planning. That being said, is FreeCAD what you’d recommend for a free/low cost CAD and/or solid modeling tool? If you don’t mind hearing a funny French Canadian accent, I’ll even be willing to record a video. If you want you can supply me a sketch you’ve done and I’ll give you specific advice on it. Of course this only covers the surface of the matter. This advice comes directly from the developer of the Sketcher internal solver, who told me the length constraint requires more calculation by the solver.
For vertical and horizontal dimensions, use the It should only be used when you need to set an angled dimension. When using dimensional constraints, use the I recommend centering a rectangle to the origin because this will allow you to use mirrored features later on. Simply select two diagonally opposed points on the rectangle, then the origin point, then apply the symmetric constraint. The symmetric constraint can for example be used to center a rectangle on the Sketch origin. This is a bug that will need to be addressed by the devs. I’ve witnessed that when many symmetric constraints are used in the same sketch, it can lock up elements that are not fully constrained. The Sketcher is still very young, v0.13 is only the second stable release which includes it. Symmetric constraint is very useful but should be used sparingly in the sketch. If the objects are not joined, select the endpoints of each then apply the tangent constraint: this will join the points together and apply the tangency at the same time. With arcs and circles joined to lines or other arcs and circles, always make sure they are tangent by applying You can apply the equality constraint to arcs and circles, this will apply to their radii. For example, rather than dimensioning two lines that share the same length, apply theĮquality constraint between them - in case you need to change their size, you’ll only have one dim to change, not two.
You should always prioritize the geometric constraints. To the left of the separator are the geometric constraints, to the right the dimensional constraints. I am using the development release of FreeCAD, I know the order of the icons was changed, but I don’t remember if that change was done for the stable release or after that. This is the Sketcher constraints toolbar. When you hover over the icons, a tooltip will appear. To use constraints you need to select a sketch object first.
Locking down degrees of freedom is done by applying constraints. Free nurbs modeling software.But I don’t quite understand how I should be locking down the degrees of freedom within the sketch.
