The by intervals option in the Surface Parameters dialog is similar to the Raster method except that it enables you to restrict the path to a specified surface. To create a probe path using intervals, enter the number of Rows and Points per row for the probe path. PowerInspect creates a path in which the rows and probe points are evenly spaced across the surface in the u and v directions. For example:
As with the by parametric units and by normalised units options, you can use the Pattern direction and Start corner lists to change the path layout.
