Thanks for the suggestion - I'm just looking into this now, but I've found some bugs in the current implementation and I'm having a bit of trouble recreating either of these shapes. Do you happen to have a snippet of ShapeScript code to produce the left hand shape that I can use for testing?
This gives a rough approximation of the perpendicular vs parallel extrude along paths.

@jaikdean this is implemented in the latest version. Use axisAligned true
per the example here: https://shapescript.info/mac/builders.html#extrude
The existing “extrude along path” feature extrudes perpendicular to the path, like the red image. It would be useful to allow parallel extrusion along a path, like the blue image.
