Has anyone tested the affect of a loaded design binder on model stability and performance. i can see that you will definately see a slowdown on loading these items because the file is larger. we do a lot of large modeling where a single model can slow down a top line computer. one of my engineers was just curious. i have checked with my VAR and they stated that they have no reported instances of this being a problem. i am just checking all resorces. iQ Quality questions bare unique answers.
