Wow! I just used the revamped Section View definition tools in SolidWorks 2004 and must say there's been an amazing improvement!
For anyone who has wanted a user-controlled dynamic clipping plane capability, the new display capabilities are terrific with spin-boxes for distance and/or angular positioning of planes. Great for a quick series of slices in search of interference or insufficient clearance areas, thin walls or poor wall thickness transitions, etc.
If there were drag handles for finer, random movement then it would be even better.
The view settings are retained during the current session, can be toggled off/on and it's possible to save one or more section views with the native file.
Take a look. I think you'll be pleased...
