I have to engineer a wooden step to adapt
differing heights in two floors. This has to fit
within the cut walls and meet up with skirting
boards etc. Is there an app to trace around
the relevant edges and so make a pattern on a
piece of timber for subsequent fret-sawing?
It would be like a mouse, I suppose.

THis is the kind of thing that boatbuilders have been doing for
millenia. Its not essentially a computer problem.

You can laser scan things if you really need
dimensions. But it's kinda overkill.
