Use the drop down menu in the Area analysis tool and create an analysis feature... The syntax in the drawing note will look like something like this… &AREA:FID_XXXX or (ANALYSIS_AREA_1… the name of the feature) The break down is this… &AREA is the name of the parameter inside the Analysis feature. :FID_XXX is the feature ID. You can sometimes type the name of analysis in place of the “XXXX” and Creo will automatically convert it to the ID number and display the area value in the drawing.
If the model with the analysis feature is set as the active model in the drawing when the note is created then you CAN use the "name of the analysis feature" in place of the "XXXX" feature ID number. If it's not the active model when the note is created then you need to enter the feature ID number and then add a colon followed by the session ID number. Something like this FID_1234:0
To control decimal places: FID_1234[.X] X being the number of decimal places.
