For operations on existing elements in your DGN file, you have to be able to select them. You can do this manually, by placing the screen pointer over the element and entering a data point. Alternatively, you can place the screen pointer over the element and enter a tentative point first, to check the selection prior to accepting with a data point. Entering a tentative point can be performed automatically with AccuSnap or by pressing the tentative button to enter it manually.

With AccuSnap's Identify Elements Automatically setting, this process is streamlined, dramatically reducing the number of button presses required. Normally, to identify an element manually requires at least one button press, or two if you enter a tentative point first. With AccuSnap and the Identify Elements Automatically setting, you only have to position the pointer over an element to identify and highlight it — without a button press. For example, to delete an element with the Delete Element tool, you need only place the pointer over the element so that it highlights and then accept with a data point to complete the deletion. Without AccuSnap, this requires at least two data points, or a tentative point followed by two data points.
