Offset curve to get a new surface

[Julia_Ratajczak]

Hi,

I would like to kindly ask if someone has any idea how I could make a line offset by different distances (a, b), get a new perimeter and create a surface (yellow area).
The schema is shown in the picture below.

Many thanks for your help!

Best regards,

Julia

Variable offset

As a design script function. [UnequalOffset_2022-07-05_08-05-11] def unEqOffset (pgn,dst:var[]..[]) { crv = List.ShiftIndices(pgn.Explode().Offset(dst),[1,0]); cr1 = crv[0].ExtendEnd(crv[0].Length*10); cr2 = crv[1].ExtendStart(crv[1].Length*10); pnt = List.Flatten(cr1.Intersect(cr2),-1); return Polygon.ByPoints(pnt); }; UnequalOffset.dyn (8.9 KB)
