Access the Add Scale Dialog:

Open the 'Edit Drawing Scales' dialog by clicking on the scale list in the status bar or through the SCALELISTEDIT command.

Add a New Scale:

Click on the Add button to open the 'Add Scale' dialog.

In the 'Add Scale' dialog, you will need to specify the drawing units and paper units for the new scale.

Enter the Required Scale Values:

For a scale of 1" = 120', set the Drawing Units to 1 and the Paper Units to 120.

This configuration means that 1 unit in the drawing will represent 120 units on paper, matching the desired scale.

Save the New Scale:

Click OK to save the new scale to the scale list.

The new scale of 1" = 120' will now be available for use in the drawing.

AutoCAD Documentation on adding scales: Adding Scales

According to the AutoCAD for Design and Drafting documents1, the command that should be typed at the command line in order to start creating a line for drawing reference that starts at a defined point and extends to infinity in the designated direction is XLINE2. This command creates a construction line, which is a type of reference line that can help you manage accurate parameters of your drawing2. You can also use point objects as nodes or reference geometry for object snaps and relative offsets3.

 object snaps are modes that allow you to snap to specific points on objects. To snap to the centroid of a closed polyline, you should use the Geometric Center object snap mode. This mode will display an asterisk (*) marker when you move the cursor over the geometric center of a closed polyline or spline.

To use this mode, you can either:

Click on the Object Snap icon in the Status bar and select Geometric Center from the menu.

Type GCE at the command prompt or when prompted for a point and press Enter.

Now you can snap to the centroid of a closed polyline by using Geometric Center object snap.
