I have tried to find information about this and havent succeded.Anyways.
If i have a made a shell out of a box and want to fill the empty spacewith a material that i define from material database.
Is there a good way to do this?
This is basically how you'll have to do it. If the box shape is very complicated and you can't just fill it with a simple extrude then you can use the following method to get a solid body of the inside:
1. Before you shell, make a copy of the solid body.
2. Shell the original body.
3. Make a copy of the shelled body.
4. Do a combine-subtract to remove the copy of the shelled body from the copy of the unshelled body.
This will leave you with the original shelled body and a body that fills it.
That space is in fact empty. You would need to make a solid in that space in order to give that region material properties. If you make another solid body inside and de-select "merge result" you will end up with 2 distinct bodies which you can apply different materials to.
You could also use the Intersect tool.
1) Make a copy of the shelled body
2) Create a plane or surface representing the filled level
3) Use the Intersect tool to create the filled portion
Oh that is even easier, unless maybe there are a lot of openings that would need to be covered.
