Re: [Feature Request] Concentric constraint in the Sketcher

One more important use case - when there are multiple arcs in a sketch, it might be hard to identify their centers.

Also, the difference between coincident and concentric constraints may become more visible in the case of 3D sketches but those are not available in FreeCAD's sketcher.

Re: [Feature Request] Curved slot tool in the Sketcher

Generally +1, but... I think all such tools (rectangle, centered rectangle, rounded rectangle, create regular polygon and slot(s)) should be dropped from FC code and replaced by one universal tool "Insert predefined sketch fragment" plus library (user editable) of definitions for such thi...

Re: [Feature request] Fillet with variable radius in Part Design

It was discussed a few times and there's a GitHub feature request for it but unfortunately, so far no actions were made to realize this. I agree that it would be good to implement it.

It's still pending review and should come after tool setting merge.
Great, thanks for letting me know :-)

Re: [Feature Request] Concentric constraint in the Sketcher

obelisk79 To be honest, I'm a CAE guy and I don't use commercial CAD software too often. I will ask on their fora, maybe someone will provide a more detailed answer regarding the differences between those two types of constraints. From the user's perspective, it's just a matter of what you select (...

[Feature Request] Concentric constraint in the Sketcher

Hi, commercial CAD software typically features concentric constraint for sketches. It's similar to coincident constraint applied to circle/arc centers but has some advantages over it: - it can be useful when arcs with large radii are involved and it's necessary to zoom out and look for their centers...

Re: [Feature Request] Curved slot tool in the Sketcher

@drmacro Thanks, I haven't seen it. I would still prefer a built-in tool since curved slots are very common but a macro is fine for a start.

A rounded rectangle tool was implemented in 0.20 so maybe you could extract the script for curved slots from that repository and add it to Addon Manager ?

[Feature Request] Curved slot tool in the Sketcher

Hi, curved slots are quite common in machine design and yet FreeCAD has a tool only for straight ones. Two years ago a user shared his macro for curved slots but it was abandoned: https://forum.freecadweb.org/viewtopic.php?t=43630 I think that it would be great to have a tool for curved slots implem...

Re: two-body part (mesh seperately) FEA error

I guess you want the .inp file, but this extension file couldn't be attached, how should I send it to you? Actually, FreeCAD’s project file (.FCStd) would be sufficient. As for the nodes missing tied contact, was it because that the tolerance value not appropriate? Yes, it can be the case. But too ...

If you can describe this curve using equations then this macro may help: Macro 3D Parametric Curve.
