Extract geometry from shape

Hi there! How can I extract the _exact_ geometry from a shape? Example: I have loaded a shape into OC and explore it using Topology Explorer. But how can I figure out if e.g. a face is a circle or if an edge is a line or a curve??? Are there any methods included?

Best regards, Jan.

Have a look at the BRep_Tool class.
