Cylinder Evaluation Methods.

Cylinder can be evaluated either in 2D as circle center point locations or in 3D as an axis comparison along a length. Settings in this section control the way that the specific feature is evaluated.

The position of measured cylindrical holes or pins can be established in either of 4 ways depending on the users needs. These methods are as follows:

 

2D Projected Evaluation Methods:

 

3D Axis Evaluation Methods:

Choose for me (Automatic). This is the default used when creating datums and checks with cylindrical features. In this mode, the evaluation method is determined automatically based on the number of measurements. When set to this option the following designations will be made: if one point is associated, trans-axis Center pos. Meas. will be chosen; if two points are associated, then Center and Surface axis Meas. will be selected; if three to nine points are associated, then Center & diam at nom. direction will be selected; and if ten or more points are associated then Full Cylinder eval will be chosen.
