Rounding curve for 2D model

I have a 2D model with a sharp corner, such as a square, does Coreform has the capability to round the sharp corner? I know Coreform has the capability for 3D model to round the sharp corner " modify curve <> blend radius <> ", is there a similar command for 2D model?



Yes. Example:

create surface rectangle width 10 height 5 zplane

tweak vertex 1 fillet radius 0.5
