I calculated the area of the duct fitting, but I’m not sure what its units are

by default imperial , you can just add a node to convert… and you will see. check out topics like this Converting units Syntexerror?
I’ve tried the feet and inches, and the numbers are ridiculously large, and is there a point that shows the unit directly after that number, for example, the square meter
Hi @1373620234 you could try something here and see if it could help
And it helped me, and I also showed the entities of the fitting, how to separate the entities of a fitting, and I wanted to see each of them
try with a solid union after elements.solid if it what you mean …
I’m sorry I didn’t make it clear, but I took the elbow in the picture and took the entity and moved it out so I could see it, and the list showed that the elbow had three solid, but I only saw one solid, how do I see three solid?
Is this node merging entities? My fault, I didn’t want to merge the three entities, because there are three entities in one elbow, but I only saw one in Revit, and I think they coincided, so I wanted to separate them and see each one
thy sir
allright but isnt it what you already do ? the reason you have 3 solids its because you family is build by 3 solids as you will see if you go to edit family and take a look
Thank you very much, sir. Which node is used to extract the entity surface?
you could try element faces instead of element solids, i think or a PolySurface.BySolid from your solids and polysurface surfaces or just an explode…try play with it 
I tried, and he generated more and more surfaces, and I was confused, so he made a polysurface for each entity, and then generated each surface of the polysurface, so my ultimate goal was to calculate the surface area of the duct fitting, and my idea was to list all the entities in an elbow, and then each face of the solids, and finally just keep the faces that weren’t in contact with anything
