An offset circle remains a circle. An arc scaled in both X and Y remains an arc. A split arc makes 2 arcs. But the result of an offset applied to an arc converts to a curve. It will therefore not accept a radial dimension. I call this a bug. (For my extension I have to look at each curve, see i…

I get arcs when I offset an arc. o need for a plugin. [offset]

[image] Wegnant: Offsetting an 90° Arc needs to create an 90° Arc again Emphasis added. I don’t recall how the Offset tool works and am not in a position to try at the moment. Are the arcs created by Offset exactly 90 degrees?

[image] TDahl: Are the arcs created by Offset exactly 90 degrees? They are when I offset a 90° arc.Same with other arc angles. Here’s a 90° arc and a 63° arc. [arcs]

[image] DaveR: They are when I offset a 90° arc.Same with other arc angles. OK, groovy! Thanks for taking the time to clarify. Perhaps @Wegnant can explain their observation of apparently different behavior?

You’re quite welcome. I wind up using Offset frquently in the mechanical objects I model and leverage the arcs from arcs thing all the time.

[image] TDahl: he arcs created by Offset exactly 90 degrees wow…i really need to understand better whats going on. DaveR your absolutely right. I really had to search hard for the Issue. Here is what happens. I Offset the Arc (Bogen) and it creates a curve (Kurve) not an Arc… The segment cl…

What are you doing differently than I showed? Clearly I am getting new arcs, not curves when I offset from an arc.

@Wegnant can you try doing what @DaveR did and offset just a stand alone arc, with no underlying geometry? I am wondering if offsetting an arc to a place where it intersects existing geometry causes it to become a curve.

I seem to remember that this was once an issue, but trying in the current version I got the same results as Dave. Was this corrected in v. 2023? @Wegnant seems to be using 2022.

I only showed the stand alone arcs for offset because I didn’t have a model in progress but I get the same results even if there’s other geometry. As I wrote, I leverage this frequently in my modeling process.
