New Sum Function

**Now in zztakeoff you can sum certain properties up to the parent item if you like. **

If you would like to create or use an existing property, when you are ready turn the property into a formula by clicking on the gear on the right top corner of the property window.

**Common Formulas **

• sum('area') this will sum the areas of any child items
• sum('volume') this will sum the volume, this might return cubic feet, so you may have to keep an eye on that.
• sum('qty') this will sum the qty's of any child item.

A quick note on this, there will be a chance of creating a circulator loop if you use sum qty's so be aware.
