The Generate Project Estimate dialog acts like a viewer for your project estimate. If you want to save the estimate to a file, you need to use the Save and Close tool. By default, estimates are saved in the same directory where the project is saved. The file extension depends on the currently selected report template.
To save the current project estimate:
In the Generate Project Estimate dialog, select File > Save and Close, or click the Save and Close button at the bottom of the dialog.
To save the estimate using a different file name or save location:
In the Generate Project Estimate dialog, click the Browse button next to the Quantity Report File edit box at the bottom of the dialog.
In the Report Filename dialog, select the location where you want to save the report.
In the File name edit box, type the name you want to save under.
Click Save. The report is saved under the specified name and location.
