Hi

I have a an STL model of a human head. I want to measure the distance across the surface of the model between chosen points, the points of interest are based on ratios of head circumference, distance between the ears ect. I have inserted some images to illustrate what I am trying to describe. How do I go about doing this?

The second challenge I have is once I have selected a bunch of points over the surface of the head from careful measurements over the surface, how do I extract those points and flatten them onto a 2D plane. In such a way that if you covered part of the head with the 2D plane it would line up with the points of interest on the head like mask.

Previously I have only designed electronics enclosures in Solidworks and I don't have a lot of experience designing or messing around with complex curved models. Any help would be much appreciated, I am in way over my head (excuse the pun).

Kind regards,

James

Hello,

(I had to Split Entities on my curve because path length dim needs more than one segment, that's why there's a dot midway)

Note: The approach I used in the equations handling (w/path specific GVs, etc) can be possibly streamlined, but the concept is there.

[EDIT: one thought on this is to have just a 10% GV for each path and the points' distance will be multiples of this.]

I hope this helps.

Cheers,

Kevin
