Take-off group

A named line in your bill that several measurements add up into.

Why you would use it

So a bill reads like something you can order from, rather than a list of every click you made.

For example

What to do

1. Create a group in the Groups tab.
2. Pick it, so what you measure next goes into it.
3. Measure.

Going further

A group carries the waste, any multiplier, deductions and a manual adjustment, and can turn an area into a length — so many square metres of roof becomes so many metres of sheet at a given cover width.
