Volume Measurement in an Assembly

[SDKevin]

I have a somewhat complex assembly with nesting cylindrical parts. It is a pneumatic system with o-rings separating the active chambers. I want measure the volume of two assembly variations to compare them.

I've seen some suggestions of making a solid in place of the volume but in this case that would be very time consuming and probably not accurate.

I'm considering saving it as a solid and doing some Combine magic.

Any suggestions on how to find the volume?

Save assembly as part, and then outer faces. Knit inner faces into solid and measure them

OR

Offset internal surfaces by 0 distance, knit inner faces into solid and measure them

That sounds slick. I'll try it.

Edit:

Save assembly as part, and then delete outer faces. Knit inner faces into solid and measure them
