Is there a way to intersect two parts?

If I understand, you want to combine two parts into one, correct?  You can do this with the "Merge/Inheritance" function in part mode or the "merge' operation in assy mode.

Doing it in part mode eliminates any parent child relationships between the merge and an assembly but requires a coordinate system (or using default placement) to locate the parts together. Doing it in the assy uses their relative placement in the assy, but makes the assy a parent of both parts.

In both cases, it takes the geometry of one and adds it to the other. If you want to create a new part with the geometry of both, you'll need to create an empty part and perform the merge operation twice to bring in each of the other two parts.

Boolean operations are generally done using surfaces (quilts) in Creo / Pro/E.

If you want to "AND" the two parts, you'll probably have to do something like:

• Create a copy of the surface quilt of each part (within the part itself)
• Create a Publish Geometry of the copied quilt (within each part)
• Create a new part and create a Copy Geom referencing each Publish Geom
• Merge the two quilts together (by toggling the 'kept' side of each quilt, Merge can perform AND, SUBTRACT or OR between two closed quilts, I believe)

What's the application?
