Hole Pattern Generator

Generate rectangular grid hole coordinates from a start point, column/row counts, and spacing. Output is ready for CNC programming and inspection. For circular arrays use the Bolt Circle Calculator.

Formula and use

X_ij = StartX + (j − 1) × X spacing, Y_ij = StartY + (i − 1) × Y spacing

i = row index (1..rows), j = column index (1..cols). Numbering follows the selected order.

Use this for grid-like fixture plates, hole grids on manifolds, or any rectangular pattern. Coordinates can be pasted directly into G-code or inspection reports.
