Automatic dividing of pattern feature with parameters

The input parameters:

SPACING (required hole spacing)
MINIMUM_OFFSET (minimum distance from the boundary)
LENGTH (total length)

The output parameters:

NUMBER_OF_MEMBERS (number of members in Pattern feature)
OFFSET (real offset from the boundary)

Write into Relations: Tools/Relations…

NUMBER_OF_MEMBERS=(floor(abs(LENGTH-(MINIMUM_OFFSET2))/SPACING))+1 OFFSET=abs((LENGTH-((NUMBER_OF_MEMBERS-1)SPACING))/2)
