Autodesk Quantity Takeoff

[#1]

I am using quantity takeoff to record measurements from 2d PDFs. When using the program I can take measurements and then organize them into groups.

The next day when I open my project back up, All the groups remain, but are empty. All the takeoffs I created are all on the top level in the takeoff tree.

Any ideas on how to stop this from happening?

I am having the same issue and have searched the internet and came up with nothing. It is like my project never saved, however the file has a time stamp that says otherwise. If you figured it out let me know!

Sorry, I never found a fix. I have resorted to uniquely naming each wbs measurement instead of creating groups. The last time this happened I lost a whole day if work. It's hard to take those kind of chances. Sent from my iPhone

It appears the hot fix for the 2013 QTO fixed this issue
