Averaging curves

Hi

 

I am completely new to autocad using atuocad 2021 on a windows 7 machine.

 

I'm a violin maker and often am asked to make a copy or a model of a famous violin and sometimes I only have a picture to go by.  So I already know how to load up a picture and sketch the outline. That's pretty simple.  However with some of these instruments being 400 or more years old there is almost always left/right or front/back asymmetries.  If I sketch both the front and back, that gives me 2 outlines.  If I then mirror those I now have 4 outlines.  I can overlay them and see the differences brought about by age.  All pretty simple so far.

 

Is there a function available that could generate a 5th curve, being the average of the previous 4 (hopefully in autocad, but doing this through another piece of software is also perfectly acceptable.)  The computer would definitely be much more accurate at doing this than I would by eye.

 

Thank you

Steven
