Converting Lines to a shape

[jamesn320]

Hi, I'm using SketchUp to produce CNC cutting files, the raw information comes in from another software package, 3rd Planit, and arrives in Sketchup as a line or curve made up of lines. For example, here it is in 3d Planit:

In Skechup it comes in like this:

I there a plug-in or tool that means I can select all the lines and curves and convert them into a solid object, such 9mm ply. Basically, a rectangle that followed the line/curve. I know about the Follow Me tool but there are hundreds of lines.

Something that could easily give me this.

I'm using Sketchup Pro 2020.

Many thanks, James.
