After finding how to get a note to auto update with information from part configurations ( https://forum.solidworks.com/thread/225126 ) I am now trying to get that information in the note to update based off the parts dimensions. I made global variables (next to the blue line) and pulled them into the custom properties (line 1 in the custom properties window), which works great. However I need to show those measurements in ft and inches, with fractional inches. Ive not been able to find any format syntax that I can put in the custom properties window make this work, so I tried to force it by working off dimensions. So I made a part based off the L W Th and used the override units option on the sketch dimensions. The global variables next to the red line are pulled from those dimensions, the 3/4" came in as a fraction, but the 20 and 14 remained in inches only, and all 3 display in plain decimal inches when pulled into the custom properties window (line 2). Sqaure one, here I come again!!

Is this what you're looking for? I'm honestly not sure if the fraction conversion is robust enough to work with all values since my file crashed and my equation table won't rebuild correctly but it may give you a start. I was in the middle of trying to get the fractional inches to work on the width and length but it crashed before I could do that. Currently it's in feet and fractional feet (not useful, i know)

I hope this helps.

Custom Property Equation:

PL "num frac th@Part_Empty.SLDPRT"/"den frac th@Part_Empty.SLDPRT"" x "whole len@Part_Empty.SLDPRT" "num frac wid@Part_Empty.SLDPRT"/"den frac wid@Part_Empty.SLDPRT"FT x "num frac len@Part_Empty.SLDPRT" "num frac len@Part_Empty.SLDPRT"/"den frac len@Part_Empty.SLDPRT"FT LG
