You can import surface bodies from an array of sources (see Geometry Preferences). Surface bodies are often generated by applying mid-surface extraction to a pre-existing solid. The operation abstracts away the thickness from the solid and converts it into a separate modeling input of the generated surface.

Surface body (see Body object reference section) models may be arranged into parts. Within a part there may be one or more surface bodies; these may even share the part with line bodies.

Parts that feature surface bodies may be connected with the help of spot welds and contacts.
