How to create Services in the marker sidebar, assign marker groups to them, reorder and delete them, and where Services appear in the Live Legend, the Excel export and Auto Takeoff.

Pipe Size Badges
How ZeroCount reads pipe sizes from the drawing, how the Ø badges on the mask bar work, how to add a size and drag a badge onto a masked run to file it under that size group.
Splitting and Joining Runs
