The Mystery of the Dimension's Precision

Anonymous — Tue, 13 Sep 2016 14:45:30 GMT

So here's a good one for Encyclopedia Brown:

Background - I created 3 templates - one for .iam's, .ipt's, and .idw's. These templates talk to each other, using Parameters and iProperties to eventually auto-fill a variety of fields on the final drawing's Titleblock and Parts List. Our default precision is 1/16" (fractional) on all templates, and on the final drawing, the User can change the precision if they wish. These templates are relatively new and we're still flushing out bugs.

One feature of my templates is that based on dimensions you put in a Part, the description is written as, lets say, PL 1" x 1/2", which is a plate, 1" wide and 1/2" thick. This description is then called up by the Parts list on the final Assembly Drawing.

The problem - One of my test-driving Users dimensioned his Part as, let's say PL 5" x 1/32". He created the part, placed it in an Assembly, and finally created the Drawing. He did all of this without closing any of his windows, so Part, Assembly, and Drawing are all open. Upon seeing the Parts List called up as PL 5" x 1/16", due to the default precision settings, he went back to his Part, Parameters, Custom Property Format, and changed the Precision to 1/32". He then saved the Part, and changed tabs to the Drawing, where the Parts List now read PL 5" x 1/32". Success! However, once he saves (and closes) the Part, with the Assembly and Drawing still open, the Drawing Parts List reverts back to PL 5" x 1/16". Failure! When we re-opened the Part again, the Precision had reverted back to 1/16", even though we had definitely saved.

I tried to replicate the problem on my machine (admittedly with what was likely a less-complicated assembly), and I was unable to. The Precision remained changed.

The TL:DR here is that when one of my Users changes the precision on one of his parts, it doesn't remain changed after he saves and closes it. For reference, he has the Part open in an Assembly and Drawing at the same time. I was unable to replicate the problem on my machine. Not sure what's going on here. If anyone has some insight, that would be much appreciated.

Thanks,

-Luke

Hi nealon.luke,

Do these files have illogic that help them talk to each other? Can you post examples of these templates?

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

Thanks, Curtis. You didn't actually give a solution, but the error is definitely in my iLogic code. Turns out one of my rules has been misfiring (or, more likely, since computers can only do what you tell them to do, I'm miscommunicating) and keeps changing the precision back to 1/16.

Gotta get on that fix.
