I'm new to Check-Mate and I'm trying to configure an existing checker to check if the part or drawing has an attribute already set. The one that I found that may be suitable for this is "Check Single Part Attribute" or "Check Single Drawing Attribute". However this is how far I have come. I dont know how to configure it to check if the Weight Attribute is set on the part or drawing. How can I do this?
Looks like Tony Salerno (the Check-Mate product manger) is out on vacation today, so I'll go ahead and answer with some somewhat dated material that should still answer your question. :-)
First off it looks like you've found the right template checker(s) already. Nicely done.
The document linked here is the "take home for reference" packet from a training course we taught at PLM World several years ago. The section you'll need is Activity 8, on page 44: "Using a Template Check". (This is a case where we've prepared the skeleton of a check for you, and you just need to populate some specific bit of info -- in this case, which specific Attribute you're wanting to see.)
