Enhancements to rib functionality

I use ribs a lot and in general they are very robust but itwould be good to have a few extra tricks in the bag to helpworkflow:

1. Being able to stop ribs automatically extending to the sidewalls. A lot of the time I need to draw a very specific rib networkand have a rib end at a specific point. If there are no side facesto prevent the rib extending, it goes all the way to the side wallof the part. This is a pain as it means that you cannot use the ribtool in certain layouts without this happening (yes you can createthem side on but doing them from the top is a lot easier in manysituations).

2. Rib sketches that can be closed shapes rather than open curves(though if 1 could be done the need for this would diminish). Theworkaround I have for 1 is to not use a rib and use an extrude tobody - but of course you cannot get the rib thickness at the facethen (well you can but it requires an extra feature or to usingdraft).

3. Ability to start the rib offset from the sketch plane - just asyou can with standard extrudes.

4. New kind of rib that has one end of the line or curve at thesketch plane or offset level, and the other side contacting thebody face or at a specific height from the sketch plane - would beidea for hole boss ribs. Extending this you could add points ontothe line or curve and set levels - the interface could be similarto the variable fillet.SolidworksParts And Features
