Measurement categories 
This button allows you to set the categories which constitute a concurrent, independent organization of measurements. Using categories you may classify your measurements in various ways, such as work carried out by subcontractors or your own crew, building level, etc.
Click on the 
button to view a list with the various
measurement categories. There is a default category ‘Category 1’ in every new
project. To add a new category, click on the field above the list, type its
description and press Enter. You can change the descriptions at
any time.
The measurement categories are project
specific.
Categories are used to
group measurements. (See Appendix/Filters/Sorting)
