Request: Bevel, Round for polygons

[seghier]

Hello
Can you add Bevel, Round as separated option for input polygons without using offset , like union

[AngusJohnson]

How would the size of the rounding/ bevelling be determined if there is no offset distance.
Are you not proposing to negatively offset by X and then positively offset by the same amount?

Like in cad softwares , Autocad for example.

Are you not proposing to negatively offset by X and then positively offset by the same amount?
This works with closed polygons and holes , but not with opened polygons

[AngusJohnson]

What you're proposing would require an entirely new algorithm. And as I doubt that would have wide appeal, it's not something I'm likely to consider implementing any time soon. Sorry. (IOW, I have lot's of other things that I'd like to do first 😁.)
