How to create an internal surface out of a 3D model with an inner void

[Anonymous]

I have created solid 3D model in assembly mode in Inventor. This model contains an inner void, and I am trying to extract the surface model from this void. So far, I tried the following:

1) Create a part from the assembly using the "Create Simplified Part" command.

2) In the newly created part model, close all openings in the model by creating an extruded cap. That way, I would have closed void.

3) Continuing in the part model, use the "delete face" command, and selected the void/lump option. This would remove the void.

Now, I am trying to figure how to subtract the shell volume from the full volume (without the void), in order to generate the surface of the void. . Please advise.

If you have already constraint your components together, you could create a new component in the assy. Then use the copy object command and either select the faces or bodies you want to copy into the inner void part as surfaces (bodies or individual surfaces. You can keep adaptivity on for the moment as you work through your design. Then use the sculp command to find the enclosed body. This will only work if there is a true closed void. If not, you will have to close it.

Please see attached to see if this would help or not.

Have a great day!

Just another video showing the "Copy Object" workflow..

Hi! There are a few ways to do this. Here is one way. If the inner void becomes to a part, you can use Thicken/Offset -> Surface -> distance = 0 to create a surface body based on the inner void. If you want to remove the inner void, you can use Delete Face -> Heal -> select all the inner faces.

Many thanks!

Thanks everyone's replies. I think I am close to figuring out how to create the internal surface of the inner void of a 3D model.
