Probe to anlysis feature

A quick search for "creo simulation live probe" yields among other things, the following:

The help file information contained therein tells one how to save a probe in the model as a saved analysis.

Using saved analyses in relations is something I've done for stuff like getting the area of a complicated surface, using a measured distance, etc. It's a nice thing to be able to use, you just have to look into the syntax of how to get the values for your particular saved analysis. i.e. for an area measurement I can assign the measured value to a parameter via a relation like this:

areatot = AREA:FID_MXAREATOT

In this case the pertinent information is as follows:

"areatot" is the parameter I want to assign the measured value to.

"AREA" specifies I want the measured area. for volume it would be "VOLUME", etc. You'll have to figure out what the particular value you want is called by Creo to get to it.

":FID_MXAREATOT" says I am asking for values saved in my model as "MXAREATOT", a name I assigned to the saved analysis when I created it. The ":FID_" is syntax needed to refer to the analysis.

Hopefully this will get you going.
