Hello!

Is there a way in FreeCAD to round off the corners of shapes specifically like this? Without rounding the edges themselves (i.e., the rounded corner tapering off to “zero” at the edges).

Thank you

@iuvi Are you saying that you want a flat surface that is a circle at the corner?

@chrishuck I want corner to be rounded and 3 edges that's formes it are not completely rounded (just until red marks on picture)

My English not perfect but hope you get a point

@iuvi I’m pretty sure I understand what you mean. The arcs won’t be tangent to the edges at the red points. Are all of the red points an equal distance from the corner being rounded?

@iuvi I presume this is what you’re after:

(It’s done using a revolved cut. There isn’t a one-click tool to achieve it. You have to create some datum planes and sketches to define the geometry you want before performing the revolve.)

@chrishuck thanks! it's very close what i meant yeah

As far as i could get, to implement something like that (for automatisation) i need to consider writing sort of "macros" as add'on right? To do fastly for Pyramyd's and such other sharp edges

3 red points can be moved accordingly

@iuvi To have a one-click function, you would have to write a macro that takes the three pre-defined points and a user-entered radius to automatically construct the necessary geometry. I would say it’s an uncommon geometric construction for most applications, which is why it’s not a built-in function. That said, it’s not impossible to be turned into an automated function if it’s something you encounter frequently.
@chrishuck Thank you very much
