Exists

[MikeThomason]

In the relations function list there is an "exists" function. I'm wanting to write a relation that would copy the value of one of two possible parameters. We have three different "legacy" parameters that were used for the part description and I would like to consolidate into one. Legacy partscontain one of the three.

Does anyone know the syntax for using this "exists" function? I've looked all over the PTC website and documentation but can't find anything.

Thanks in advance,

Mike Thomason

Thanks for the replies... summary below:

This is the relation that works for my specific problem:

if exists("part_name")
part_desc=part_name
else
if exists("description")
part_desc=description
else
part_desc="ENTER DESCRIPTION"
endif
endif
