Shape for line and curve

### The Problem

I need a shape option for the line and curve tools.

### A Solution

You can add a shape parameter to the curve and line commands after defining the shape, e.g., using the select tool. Add the shape function and select several points on the plane that would define the shape and thickness of the line and curve tools. Example:
//sel shape (select several points using the pos command or the manual selection tool), then select the //curve shape pattern.
