#### Placing Hits on a Surface

In many instances it is necessary to precisely position the hits on a surface (i.e., plane, sphere or cone measurement). To do this:

1. Move the cursor to the position where you wish to take the hit.

2. Hold down the left mouse button (do not move the mouse).

3. Release the button. PC-DMIS will program the hit at that point.

The cursor must be held in one position while holding down the button. Otherwise, PC-DMIS will misinterpret your intention. If the probe tip snaps on to a feature after the button is released, then the mouse was moved during the process. Press the ALT + "-" (minus) key combination to remove the hit and begin again.

Note: Precise depth must be set before placing discreet hits on a cone, sphere, or plane.
