Linear Pattern
Information required:
 Linear pattern type (array or frame)
 First hole (1st hole of the pattern)
 Holes per row (number of holes in each row of pattern)
 Hole spacing (the spacing or offset between each hole in the row)
 Angle (the angle or rotation of the pattern)
 Depth (the target depth for drilling in the tool axis)
 Number of rows (number of rows in the pattern)
 Row spacing (the spacing between each row of the pattern)
Example: Enter data and execute a linear pattern.
Type of pattern: Array
First X coordinate of hole: X = 20 mm
First Y coordinate of hole: Y = 15 mm
Number of holes per row: 4
Hole spacing: 10 mm
Tilt angle: 18°
Hole depth: -2
Number of rows: 3
Row spacing: 12 mm
A linear pattern can be mirrored by entering a negative
spacing, and rotated by defining an angle of 180°.
