Type QREP in the command line or click the button in the Add-ins tab ribbon to start the command. Select the objects to quantify, then a dialog box will appear.

At the top-right of the dialog box, a list displays polyline layers (prefix L:) and block names (prefix B:). Select the polyline layers and block names you want to quantify, edit the Element name (optional), and click the Add>> button to add them to the list below. The layers and blocks you add to the list will be quantified.

Next, choose whether you want a Detailed or Simple report.

Below this, select whether to include stations. If selected, the dialog box will temporarily disappear so you can pick a polyline or Civil 3D alignment. If you select a polyline, enter the station increment and initial length. If you select a Civil 3D alignment, this information will be filled out automatically.

Press OK to save the report in the same folder as the current DWG™ file.

The report will be saved in .txt format, and the content can be copied and pasted into Excel.
