Hi everyone!

I am doing a compression test to an oval shape (it would be a quarter of a hollow sphere, more or less, although it's irregular since the thickness of the ovoid varies from one point to another) Once the compression is finished, I need to know the gap which is below the ovoid at some points from the base.

I put a rubber witness, which does not offer resistance, and activated its total deformation (since it would mark exactly the distance between the base and the points I want to measure) but it gives a lot of problems for solving the exercise. In fact, the compression itself, without the witness, already gives some problems if I put a high displacement.

My question is to know if a direct measurement can be made with any command from the point I want to measure of the ovoid, to the plane that makes the base.

Regards, and thank you very much!
