Step-by-step instructions :

These instructions assume that you are in the Drawing Editor , that you are using a 3-button mouse, that the User and Site Options > General > " Point location target " is set to ' Fancy ' ( ), and that you use mouse bindings similar to those shown in the following illustrations.

Before using this tool:

Optional: Confirm that User and Site Options > Drawings > " Always show Circle Edit window " ( or ) is set the way you want it. That option controls whether or not the Circle Setup window opens (in step 4).
Optional: On the Layer Panel , select the layer you want to add the circle to. This step is optional because you can change the drawing layer on the Circle Setup window.
Optional: Unshorten a member detail before adding a circle if you want Detail Members to later be able to correctly preserve ' User-created ' annotations. Unshortening also ensures that measurement tools such as Dimension Add or Ruler or Construction Line Add using BSCL reliably produce precise and consistent results.
