The ability to measure and section is totally controlled by Adobe and their "Author" license. So a 3D PDF coming straight from Solid Edge will not have measure/section ability in the Adobe FREE viewer right out the gate. (It can however contain a complete PMI dimensioning scheme or exploded views, making the need for these things considerably less). However, the Solid Edge produced 3D PDF can be brought up in an Adobe author product, measure/section enabled and the file resaved. Then, any Adobe free-reader seat can measure and section.
For Surfacing -- More accurate? No. But more automated? Yes. Certainly history-based (what we call "ordered" in Solid Edge) provides a good level of automation for surfacing insomuch as editing an upstream curve can cause many automatic downstream edits. Of course Solid Edge provides a complete ordered (history-based) environment in ADDITION to all the Synchronous stuff that is making news. And of course Solid Edge is the only system that allows you to create a Synchronous basis for your design and then create ordered features (such as surfacing) dependedent on the synchronous base.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
