Planar Polyline (Closed) replacement in Unreal Engine 4

Development Getting Started & Setup

What could You recommend for replacement of NURBS’ Planar Polyline (closed) or even Planar Curve.

I expect to do good cutting edges for trimmer maybe even with beveled corners at that level of project’s creation.

I have found an option in MESH TOOL as Trim Sheets, but excuse me, want some more.
Planar polyline (closed) I can extrude STRAIGHT for Surface, don’t need polygon in Rhino 1.1;2.0;7 That I can use as cutting edges for trimmer inner or outer and finally can use for cover surface.
Can not find good plugin to solve that issue.

Good practice with: Rhinoceros 1.1_2.0_6_7
Please send some info.

I have found something similar to PLANAR POLYLINE (closed)
in Unreal Engine 5.2 named PATHS. Mode Modeling F5+Shift under Create command.
Two paths’ commands: Path Extrude, Path Revolve.
Quite good and very nicely.
