I have a further question related to this. I have a model consisting of line and solid bodies which I've developed in SpaceClaim. Within SpaceClaim the line and solid bodies are made up of several different components but when I open Mechanical all of the line bodies are one part and all of the solid bodies are one part.

In the image of the Mechanical window I've highlighted the solid geometry part to help show what I mean.

Is there something that can be done to seperate out the geometries in Mechanical into seperate parts?
