Draw Vent Pattern

This tool draws an array of ventilation slots (air holes), often used in electrical enclosures or machinery panels.

Slot Generation

Creates elongated slots with rounded ends.

Array Function

Automatically copies the slots upwards to create a ventilation grille pattern.

Shape Adaptation

Depending on the quantity and dimensions, the shape representation might simplify (e.g., to a simple rectangle or semi-circle for large counts/small scales).

Input

Requires a start point, slot width, slot height, top fillet radius, total count (vertical array), and pitch (vertical distance between slots).

The ventilation hole pattern is drawn.
