I suffered the same frustrations using beams in Pro/Mesh v2000i2 when we switched but I found a few methods to make it easier. We use beams to simulate pin/bushing connections and use alot of beams to locate a node at the center of a hole with a pinwheel of beams to the edges of the hole. As long as all the datum points around the edge of the hole are created as one feature, all the beams can be created at once by choosing the feature instead of the single point. I also rename the desired beam property so that it is listed first alphabetically when creating beams so that it shows up by default in the beam dialogue box. The alternative is to use about 10 mouse picks to change the property of the beam (at both ends) to the desired property. This helps alot when creating lots of beams with the same beam properties. The pro/e guy here created a few simple map keys in Pro/E to ease the creation of datum points to be grouped into features, thereby bringing the functionality to the tolerable level.
