This article describes all the ways to name and rename measurements in Kreo.
In Kreo 2D Takeoff you can specify the measurement's name right before its creation.
To do this, select the relevant measurement tool and pay attention to the panel directly above your drawing. There you will see the Name caption and the item's template name (Polyline / Rectangle / Polygon depending on the element you're measuring). Click on the template name to modify it. As soon as the name is created, press the "Enter" button.
Note! In the same panel, you can specify the measurement's colour before its creation.
If you need to rename any measurement on your drawing, open the Measurements menu and hover over the end of the relevant measurement's name. Then you will be able to modify it.
Read here how to rename multiple measurements at once.
