I swear I remember seeing that there was an enhancement in WF5 or maybe Creo 1 to allow you to sketch a series of lines, multiple open sections, and extrude that as a thin feature. They showed it creating a network of ribs in a plastic part.
I'm trying to do this in an internal sketch (a simple T) in an extruded thin and Creo 2 is giving me the same old ' multiple loops must be closed' error. I tried again with an external sketch and got 'Intersecting entities encountered in the section' and Creo refused to use the sketch.
Am I dreaming about these extruded ribs? If not, how do I do this?

After playing with this tool I find it quite useful, but rather specific in application.
The open end points of your sketch have no bearing on the end of your ribs. Proe / Creo is going to extend or trim them at the side wall of the part. So, a 1" long line inside a 10" wide part produces a rib across the full 10". Conversely, a 10" long line over a 1" long part produces a rib only inside the 1".
