Set this advanced option to TRUE to have the snapping point in the center of circles while you are snapping to the center of circles created in the model by using polygon cuts. You may need to snap to center of circles when you need to create dimensions, for example. The default value is FALSE.
If you change the value, you need to reopen the drawing.
This advanced option is model specific and the setting is saved in the options databasedatabase file that contains the settings of model-specific general settings and advanced options
There are two options databases, the model options database (options_model.db) and the drawing options database (options_drawings.db).
