Multiple Surface Area Measuremnt

[charles]

I've got a component that has around 250 faces and i need to measure the total surface area of just the internal faces (around 100).  Is there any easy way of doing this?

I've tried the 'Add to Accumulated Value' method but you can only do a couple of faces at a time and it's very easy to loose track of what faces you've already done.

Is there no way of just selecting 100 or so faces and inventor adds the surfaces up?

Or is there a way to merge faces together easily to create 1 complex face and then i can measure that?

I've got to repeat this process for around 50 parts.

Can you Attach one of those 50 parts here?

[charles]

Unfortunately i can't for confidentiality because it's a production part for work.

[JDMather]

Can you make up a dummy file and Attach that?  (That is exactly what I am doing at the moment - just though you would save me some time.)

[charles]

Attached is a redundant part but it's similar to parts i'm trying to measure.

Everything internally needs to be measured (threads etc.)

Thanks

Before I create a video - just to confirm - you want area, not volume.

Never mind, I'll do both.  What version of Inventor did you say you are using?

[charles]

Yes, internal surface area is all i'm interested in at the moment, i'm currently using Inventor professional 2019

There is a sliver in your thread that I assume was unintentional.

This is one method of doing it (see attached part) - by closing off the ends, then create a new body that fully encases the part, subtracting the two, then delete the outer void.  Then you can just look at proprieties to get the surface area.

If the part is simpler, you could boundary patch the ends, delete the outer faces, and restitch.

I used a slightly different technique than @imajar .

You will have to subtract the area of the Boundary Patch caps if you don't want those.

This can also be done with essentially the same technique using a Derived Component that does not create any geometry in the original part file.  (Don't need to Copy Body if using Derived Component.) (Or you could simply drag the Red EoP marker up to hide the additional features, or delete them.)  Personally, I would use the Derived Component technique.

Note that you can also get the internal volume.
