What are those segments? CAD or language tips, please

Question

Inherited files with body content said to be from some unknown CAD system. To me it looks a bit like postscript. I would appreciate any tips and points wrt language description and how I could reconstruct curves/segments.

Since there are only a few tens of them, you could write a program to roughly convert them into Postscript to at least see what you might have:

newpath
0.000 0.000 moveto
41.943 15.266 64.260 53.921 1 arcto
76.669 124.293 lineto
closepath

The example file you provided seems to draw the same shape twice, with only slight variation -- I assume from the minimal drawing commands that all the files collectively add up to one (interesting) whole:
