An overview of Cost Items in the Estimation tools.
Estimates are made up of cost items. Cost items may be sent to an Estimate from a TakeOff measurement, assembly result, or added manually in Estimation.
To send a measurement from a Takeoff into a Project Estimate as a Cost Item, in the Measurements Panel right click on the item you want to send or click on the actions menu and select +Add to Estimate.
You can also check off measurements and click the "+Add to Estimate" at the top to send multiple items at once.
You have the choice to send the measurement into an existing Estimate or to a new one by selecting Create New Estimate.
For this example, I selected Project Estimate 3.
Once you have sent your measurements to the Estimate, you can navigate to the "Project Estimate" tab and select Project Estimate 3 to see them. The only cost items in this estimate are the ones just sent from TakeOff.
The cost item with Name, Unit Cost, and Description filled in had their properties addressed in TakeOff. You can also check the Source column, If it says Takeoff, it came from a measurement in your Takeoff for this project. This keeps measurements and cost items organized.
If there is a TakeOff link, clicking the link will take you to the page in the TakeOff where the measurement originated.
To add a blank cost item to an estimate, click $Add Cost Item, (if you have a drop-down bar next click "Add Manually").
The editable fields become available with required fields marked with a red asterisk and a red exclamation point in a circle. 
After all applicable fields are addressed, click the floppy disc icon on the right side of the cost item to save the changes. Use the Scroll bar at the bottom to continue filling out all applicable fields.
To add a cost item from the Cost Items Library, click the Cost Item Button.
Click into the search box and type a keyword for the item you want to locate.
For example, "2x6x12" to be used as a ceiling joist, then press enter or click the magnifying glass to search.
Any items may be added to an estimate by clicking the green "+" on the right side of the cost item, doing so will add this cost item to your Estimate.
To access your Company’s Library of Cost items, click “Cost Items ”, then click the filter icon (small arrow/triangle pointing down next to each column) next to the column labeled "Owner", check the box next to "My Company", then click "OK".
Only your Company's library of cost items will be listed.
When viewing Cost Items in the Estimate or the Library, Cost items can be duplicated by clicking on the duplicate button in the Actions menu.
You can also remove Cost Items by clicking on the Trash can button in the Actions Menu.
You may save Cost Items to your cost item library for future use on projects by checking off the items to the left side of the cost item, then use the Actions button to select add to cost items library from the actions menu.
