Hi
I have these two polysurfaces and I wanted to get the volume in between them. So I did a loft. However, because layer 1 and 2 intersect, there are parts considered in the purple volume which are basically not correct (it’s not the volume in between). How can I edit my code so that these parts are deleted from the volume in between?

Hi,
Perhaps you do not have to over complicating it, why do you not just increase the distance between the two meshes?
Unfortunately I can’t do that. Because I have to make a comparison between this option and one where the geometry has less surface roughness (I have to compare the purple volume in these two scenarios). So the distance between the two breps are set.
Anyone can help me with this?
Hi Rajeev,
Thank you for your help.
However, I don’t think this is correct because I checked the purple volume and the parts where intersect with the bumpy surfaces are still not subtracted from the volume
Hi Kiana, I managed to obtain the volume of the intersections (the red ones), but it involved rebuilding the surface you created (all the solid booleans failed). I have used Rebuild Surface from Putterfish; I’m not aware of a standard rebuild surface component.
These are the calculated volumes: the mistake is only 1.2 %
Hi Mark!
This is exactly what I wanted, thank you SO MUCH!!! I didn’t know about Pufferfish.
Hi again Mark 
One more question, now that the red volume is obtained, how can I subtract it from the purple one? I tried solid difference but it didn’t work
Hi Kiana, all the solid boolean components fail. So you have to recreate the volume with the trimmed surfaces. The volume also changed compared to the former situation. I am not sure what caused that.

Thank you Mark!! This is amazing
