Area moments with multiple sections

I'm using Area Moments component to analyse some structural elements. Is there any way to make it working with multiple sections (detached), but consider them as unique?


Try to image a simple twin C elements (UPN).

At the moment, even if I use join brep component, I have two separated Srf and so a wrong value for barycenter and Jx. 

Thank you in advance

Rhino can handle it and it can combine area properties after the fact, but that functionality never made it into GH. You can convert your geometry to meshes and use Mesh Join to create a single mesh, which will behave correctly for Volume and Area mass properties. but of course you do lose some accuracy as you are now using an approximation of your geometry.
