The original post was to consider industries, but how about polling cross industry uses? Design, reconstruction, modeling, entertainment, or production to begin with. Given the most popular use of SU promoted by Google, reconstruction would probably be its predominant use. Lucky for us minority users.

I will create a poll if one does not exist.

Search out my Height above Datum Text Tag code... http://forums.sketchucation.com/viewtopic.php?p=193238#p193238 This tool adds a piece of text at the picked point and later if that text is moved its observer reads its Z value and updates itself automatically. In your case instead of it checking its location have it check the area of a given face [don't use ids as these change session to session instead stamp each bit of text AND it associated face with a guid - perhaps based on the time * rand] and have the face update the text. I already have an 'AreaTag' tool on my 'to-do list' [but currently it's a far off number 9]

Guys, Thanks for your help! Great insight.

Good point. Thanks
