Hi everyone! 

Is there a simple way to select a group of lines (like the maze pictured attached) and turn them into rectangles?

I make these mazes using an online generator that allows me to download it either as PNG or SVG. 
Now I wanted to machine some of them and that's where the problems start.

I can make a profile cut along the vector lines as is, but the problem is I need the exact opposite: I need to clear the area **around the outline**, so that what's left is the maze itself, and that way a small ball can travel around inside the maze.

So the outlines of the maze need to be, in fact, the walls of the maze.
Meaning they will have to be rectangles and have some width.
That way maybe I can program the machine to clear the area around the walls.

Any easy way to do this with Inkscape?

Thanks!

André

Hello

After vectorizing the maze. Position a shape under the maze. And subtract the maze from the shape to get what you need
