Using an irregular shape

[Gremlin]

I want to create a layout with an irregular shape - similar to the letter U, running along three walls in a room.

I don't want to draw three rectangles to view them separately...can this be done in V5 because I can't figure out how

You can just use the drawing tools:
From the 'Shape' select e.g. the Polygon shape and insert / position as many points as required.

Quick tips: Clicking on an existing line will insert a new point in the line, Opt-Click on a point deletes the point.

You might want to place the shape into its own layer and lock it so it won't interfere with the track layers when editing the layout!

Cheers,
