In Kreo 2D Takeoff you are able to rename the whole blocks of elements at once to save your time and effort.
To do this, perform the following steps:
Choose multiple measurements either by selecting them in the Measurements panel or by selecting several items right from your drawing.
Click on the Rename tool icon placed on the left of the Filters button. Find it on the top of the Measurements panel.
Select one of the possible options there:
Replace Name option, which completely replaces the word with a new one;
Prefix option, which adds words at the beginning of the original name;
Suffix option, which adds words at the end of the original name.
Press the "Apply" button to save changes.
