Surface Area of 3d face

I have a dished end and i wish to find what the inner surface area is. I have created a model of the end, whats the best way to find the surface area.

I have been told to explode the model and pick on the suface but this does not seem to work.

Autodesk inventor seems to have the same problem.

Its a fundamental requirement when one wants to apply pressure or even to find the surface area when painting etc. See attachment

Any suggestions please.

Thanks for the reply, I have tried your method ,copied the face but when I go to properties it won't give me the area, I think your method works
on a flat surface but not on a curved surface.

I did try your measuregeom command but it's not going to work on a curved surface, thanks for your help.

Is that dish Solid of a known constant thickness?  You can get its volume with:

  (vla-get-volume (vlax-ename>vla-object (car (entsel))))

 

If you divide that by the thickness [or get a routine to do it], that should give you the surface area.

Autodesk Inventor does this just fine.

In fact, you marked Inventor as the solution.

Inventor will easily give you the area of an individual face and the total area (iProperties) of the entire part.

Hello

After having copied the surface of the solid with the command SOLIEDIT.

You can call the AREA command to know the area of this entity.
