I saw the idea for unrolling the surfaces and decided to implement.

 ![Unroll](https://global.discourse-cdn.com/mcneel/uploads/default/original/3X/3/8/389782aa5dda9ab3ecd0d4fcf9d327c34bb38ccf.jpg)

Lines to the surface edges are created from the center point on the surface. Then, a point is created on the plane from which the lines originate at the same angles. Distances are measured on the lines and a curve is created at the end points.  
Faced with the problem of creating the shortest curves from the center point to the edge of the surface at a given angle.  
Please help.

That’s cool. Thanks. I studied grasshopper not so long ago and you really helped me. Tell, How you appropriated a plane this parameter by default?
