Prepare the Hole Patterns Inputs
Enter row and column counts, spacing, and the starting origin. The generated table lists every point in row-major order.
Generate rectangular bolt-pattern coordinates from rows, columns, spacing, and an origin.
Generate a repeatable rectangular hole pattern for fixtures, plates, brackets, and CNC drilling operations.
Enter row and column counts, spacing, and the starting origin. The generated table lists every point in row-major order.
Use it for fixture layout, drilling patterns, inspection locations, and programming references.
