Hello,

I am getting a fail every-time I try to offset room boundaries in the shape of circles. They are first converted into poly-curves.  
I tried all Offset nodes I could find in the most downloaded packages…

If the room boundaries of the column is attached to the exterior perimeter, they offset just fine. (see second screen grab).

Any Idea? Are isolated circles made of two semicircles a problem for the Offsets? I tried a larger round column and it still fails.

Thanks

Have you tried [_Curve.Offset_](https://dictionary.dynamobim.com/#/Geometry/Curve/Action/Offset).

yeah, I tried all “Offset” nodes I have… at least in the most downloaded packages.

Is there a more obscure “Offset” node I should be trying?

thanks
