Delete takeoffs from Quantification Workbook with C# Takeoff API

[Anonymous]

Hello everyone,

I want to delete the takeoffs inside the items on the Quantification Workbook through the C# API (Figure 1).

I am able to get the takeoff tree from the database via the Takeoff API and change descriptions, WBS, etc by querying the database. On the debugger I am able to see the 2 children of the Item "PR01" - which are the takeoffs I want to delete (Figure 2) - along with its entity that contains the columns' names. However, if I clear the children list of this "PR01" Item, this does not reflect on the Quantification Workbook. I have also tried to find a way to do this by querying the database but to no avail.

Any thoughts on how this can be done?

Thanks everyone!
