Surface Area of the Inside of a Part

Surface Area of the Inside of a Part

Surface Area of the Inside of a Part

(OP)
I have a complex part and I need to get the surface area of the inside of the part.  I know I can select a face in measurement and see the area of the face but it's a complex part.  

I used offset surface set at zero distance to create a surface model but still don't have a good way of getting the area.  

I thickened the surface to .001 so now I have the surface area of the whole thing.  Seems like if I divided that number by 2 I would have what I need.

Does anybody know a better way to do this?  Seems like SW would be able to do it without all the thrashing around.

Steve.
 

RE: Surface Area of the Inside of a Part

Create a part (or a body) that is larger than your internal volume and do a Combine (Subtract).  This will leave you with a body that should have the same surface area as your internal volume.  Then Tools/Mass Properties should get it figured out.

RE: Surface Area of the Inside of a Part

Using the power select tool gives you alot of options that may help you.
dividing the total surface area by 2 is a reasonable approximation for a surface body but has a margin of error depending on the feature sizes vs the thickness you added think of a sphere if you add .001 to 1"
4*pi*1.001^2= 12.591 outer shell
4*pi*1^2=12.566 inner shell

thats a .0125 margin of error if you just totaled and divide by 2.

don't know how exact you are looking to be.

RE: Surface Area of the Inside of a Part

If you select the zero offset surface(s) (or the faces used to create it/them) and activate the Measure tool, does it not give the area? Note; this does not work on a Knit surface.

Hi, Steve:

Select any number of surfaces you want to measure, and press "M" (measure) key to get the area.

Good luck!

Alex
