Parameters

Instance

Pattern instance number (see Remarks)

AngleFromSeed

Angle from the pattern seed

IsOffsetFromNominal

True if AngleFromSeed is the offset from the nominal position of Instance, false if not

Return Value

To calculate Instance:

Calculate:

      For a bi-directional pattern:

           I = n2 * (i - 1) + (j - 1)

      For a uni-directional pattern:

           I = i - 1

      where:

In the pattern's PropertyManager, find n2 in the Direction 2 > Spacing and Instances > Number of instances field and find [i,j] in the Modified Instances section.
