The relation window in Pro/ENGINEER Wildfire 5.0 has several new functions not seen before. I have tried the pro/e help, knowledge base, and other sources, but have not been able to find any documentation on what these functions are for. They are: dead, edist, elen, mod, near, pow, & sign. I do not recall having access to these in WF3, and have not been able to find any information on them. Where can I find a description of these functions?
