Diameter - The value in this box defines the cone's diameter.
Length - The value in this box provides the length (height) of the cone's axis. The length parameter is only valid as nominal. PC-DMIS does not perform an actual length measurement.
Inner/Outer - This parameter defines whether or not the cone is an inner cone (hole) or an outer cone (stud).
Unlike most other laser Auto features, for the Overscan value on the Laser Scan Properties tab of the Probe Toolbox, you should use negative values.
This limits measurement in the conical region along the cone axis.
Depth - This parameter controls the location of the laser focal point in relation to the cone's outside diameter (outer cones) or the cone's center axis (inner cones). This allows you to control how the laser stripes fall on the cone's surface by specifying how far or close the laser is to the cone's surface. A depth of 0 (zero) causes this feature to be calculated at the surface plane height using data found at the lowest possible depth from the surface plane. A depth of any other value causes the software to perform the calculation at that depth.
Center Offset - This value identifies the center of the cone portion of the stud.
Search Length - This value identifies the length of the cone portion.
The depth defaults to zero for a plane feature with no extruded edges. You should only change this to a different value if there are specific requirements from your part's drawing. Otherwise, PC-DMIS unsuccessfully attempts to locate points at the specified depth. This results in a feature calculation error from the feature extraction module.
