Hello guys, i’m trying to get the surface Edges, join them to be one single polycurve and apply a given offset. My goal here is to be able to get a new surface hatched in blue. My first problem here is that even on a false state, the node PolyCurve.Offset keep rounding the edges and I don’t understand why. My second problem is that I don’t know which node I should use to get the same shape for my new surface like the one shown in the first screenshot (without deformation), not like the one shown in the second screenshot.
Thank you for your help!
Try just using a Curve.Offset instead.
Hi Jacob, thank you for your reply again. I tried all the nodes that I found working with curve offset, and all of them gives the same result. this really confuse me, i don’t know what I’m missing here. I even tried to change the offset distance from 0.01 to 0.1 to 100m, it’s always rounded
Might be how the curve was built. Provide the source data and a member of the community will likely have a look later. 
Ok will do that. Thank you
