How do I measure the volume encapsulated by a plane and an actual mesh.

[[To...]]

Hello,

I have a STL of a dome shape and want to measure the volume of it relative to a plane fitted to the top surface. I can't do this by just fitting geometry elements to the surface, such as fitting a sphere and using that to calculate it, I have to measure it to the actual mesh itself. 

Below are some diagrams:

Any help would be greatly appreciated. Let me know if I can clarify anything.

Hello, 

You should utilize the software's mesh analysis tools. Instead of fitting geometric elements like spheres, you can directly analyze the mesh by creating a reference plane at the top surface of the dome. Then, use the volume calculation feature that allows you to compute the volume enclosed by the mesh and the reference plane. This approach ensures that your measurement is accurate and reflects the actual geometry of the STL, providing a precise volume measurement relative to the fitted plane.

i am assuming this is a fairly new feature..its a new one on me.. 2025 ?

 Yes, For these features like measuring volume against fitted planes, it was made possible with the latest versions of Zeiss Inspect (2020+) and GOM Inspect (2021+).

 can you please include a screenshot of the menu path as I use Gom inspect 2021 currently and cannot find this feature. 

As an aside , to the best of my knowledge (i worked for GOM until 2021) there is no such thing as Zeiss inspect 2020, particularly that there wasnt a cross over period where the name GOM and Zeiss inspect existed at the same time ,as it is fundamentally the same software with a different name..it makes me think that potentially there may be a misunderstanding?
