When you choose Automatic from the ADD POINTS menu, the system generates the first slice at FIRST_SLICE_OFFSET from the start plane in the direction that you have specified when defining geometric references. The number of Measured points in the slice is defined by the POINTS_PER_SLICE parameter (the default is 4). If NUMBER_SLICES is greater than 1, the system generates the rest of the slices at OFFSET_BTWN_SLICES distance from the previous slice.

Similar to measuring a plane, if an automatically generated point falls off the surface, or within BORDER_CLEARANCE from the surface boundaries, the system will ignore it.

The illustration below shows automatically generated points and path for Measure Cone.
