If I have a geometry that has been generated in DM (DesignModeler) or imported from another CAD package, how can I generate the negative (i.e. fluid volume) if I only have the solid parts?
One of the easy methods to accomplish this task is to :
1. freeze the imported geometry;
2. create an enclosure solid;
3. use Body Opt/Slice Material to slice the enclosure solid with imported geometry;
4. Deleted or suppress the parts you don't need and you should be left with the desired parts.
Please see attached DM database for an example.
