Re: senoidal wave line in sketcher
If you want an actual sinewave (or at least a numerical BSpline fit to it), use the Parametric_Curve_FP macro that you can download via the add-on manager.

Re: still struggling to understand the modeling process of freecad
I am trying to make something in freecad, pretty simple actually, but i dont get it. The process if what i need to do to make this seems way to complicated when it shouldnt be haha. So i must be missing something. Below is a fin can i made in sketchup pro 2023. Took about 2 minutes. I made the cyli...

Re: Boolean Cut Fails with Partdesign
In Part Design, when you want to add material you use an additive tool and to subtract material, use a subtractive tool. The corresponding Boolean operation is done automatically. The subtractive version of revolve is groove. In the Part Design menu, they are labelled as such. As icons, they are in ...

Re: Constraint sketch based on Part 3D information
I'll try once again to figure out what you want. You have two planes, (A) the XZ plane, (B) the XZ plane rotated 30 degrees around the z axis. This is the top view of Sketch : Screenshot 2024-03-28 at 9.24.24 AM.png If we extruded this in the z-direction, the base would lie in planeA and the hypoten...

Re: Help with the 'union' command in WorkBench Part
I don't have any recommendation as the best way to go. You want to end up with a union with a single solid that will create a good mesh. You may have to experiment with overlaps to get one.

Re: Constraint sketch based on Part 3D information
i don't understand what you are talking about. le problem: I have two datum planes, both parallel to the Z axis. parallel ?? Planes aren't parallel to axes - they are orthogonal to them. Planes are defined by their normal vector and any point that lies on the plane. One plane, A, is coincident with ...

Re: Constraint sketch based on Part 3D information
You probably want to look at https://wiki.freecad.org/Basic_Attachment_Tutorial This is one important way sketches get placed relative to existing geometry.

Re: Help with the 'union' command in WorkBench Part
Better to widen the distance between the holes slightly so the two struts don't touch. I just made them slightly non-concentric as a proof of principle. Likewise, you can lift the struts off the surface slightly if you don't want them to fuse into a single object, or move them inward if you do. Free...

Re: Help with the 'union' command in WorkBench Part
FreeCAD doesn't like surface to surface contact. Moving the objects a few microns can fix it - exaggerated here. Presumably the desired object would have some clearance here.
