Surface and volum of an element

Anonymous — Tue, 09 Jan 2018 12:15:34 GMT

Hi everybody,

I need to get the surface and volum of an irregular element using the list of solids of its geometry. The doubt that I have, if an element whose geometry is done for various solids, an overlap of it can happen.

If there is overlap, the volum, as the plus the volum of its solids, would be wrong, but if there is not, it would be a good solution when we don't have a property for it.

And for the surface, if there aren't overlap, al least there would be contacts surface which would not be plus. There is some way to find only the outer surface of the geometry.

Thanks,

Javi

Dear Javi,

I should think so.

Using just the Revit API, I think you can retrieve the solids and create a union of them all via ExecuteBooleanOperation:

With that one solid in hand, query its SurfaceArea and Volume properties:

Hi Jeremy,

Thanks for your answer. The idea to use "ExecuteBooleanOperation" is useful for me, because you get a solid, and that I was trying to find out.

Thanks again,

Javi
