Hi,
Please help!
Any idea on how to use Text Fields referencing grouped objects to get cumulative area?
Hello - I do not think that is possible, currently.

Thank you for your comment. I’m open to an idea to code it, any idea?
Hello - it should be possible to make text that pays attention to some cumulative say, area,using a script but it is tricky making that ‘live’ - the most likely scenario is that you’d need to run an updater command to refresh the texts after changes are made to the source objects - is that reasonable?

I was curious about this myself. In WIP 7 you can now do math operations on text functions. Because of that , this is actually now possible. Here’s an example idea.
%<Area(“ff0ffd6e-67a8-47e2-92cc-0d863da0fb6c”) + Area(“8d13c962-f04a-40b1-8b6f-e8797ee5bac8”)>%
You’d have to string this together by hand but if you nest the %<Area(object_id) + Area(object_id)>% for each object in your group it will give you the total.

Much better, thanks Trav.

That’s a nice trick! Thanks Trav
Yeah, fun stuff. @stevebaer added a bunch of cool tricks for text functions in v7.

Yeah! this could be my main goal. I’ll do some research about it.
I hope we could hear comments from other gurus here. PLS 
@Trav we should look into making this work for groups. Seems like if we can’t find an object with a given GUID, we could look in the group table for a group with a given GUID and then perform the appropriate action on each item in the group to create a cumulative result.

Definitely, I hope McNeel guys consider this in their future development.
@stevebaer for sure. Seems easy enough to make the picker support groups. I can stitch the function together on apply.
