Utilizing the AREA Command

[cpascual]

Okay so I wanted to get the surface area of this diaphragm I just made. I only want the surface area of one side, so I just made it a surface with no extrusion. When doing the AREA command it gives me, "object has no area," so I guess the Area command does not work on surfaces. Is there another way I can just get the area of the top face of the part shown. Like should I just perform an extrusion and make it really small to get the area or is there an even more accurate way to do it. Let me know when you get the chance. Thanks.

And when I tried to pull off the extrusion trick I was thinking it did not work because it would give me the error, "Cannot extrude or sweep a non-planar entity." So I guess I can't get the area that way.

Yes, you cannot extrude a 3D surface.

 

What I will do to calculate the area of that shape is this: (1) draw a half of the transversal section of shape (with a thickness); (2) revolve it 360degrees around vertical axis; (3) use AREA command on the resulted shape - it will list you the total area of the object; (5) calculate the area of the "thickness" (that it, the area of peripheral surface), remove from above listed value and divide the result at 2.

 

For peripheral area use the formula: 2 * PI * ExteriorRadius * Thickness.

Yea thats what I was think ing I was going to have to do. Thanks for the help
