Open editorConvert & generate
Start with the material you already have
Turn images and SVG artwork into a pattern base you can continue adjusting or bring into CAD.
Image to Perforated Panel
Upload any image, generate perforation patterns based on brightness, export PNG / SVG files ready for laser cutting or CNC punching.
SVG to DXF Workbench
Upload an SVG, adjust size, position, and rotation in millimeters, then export a DXF for CAD, laser cutting, and CNC workflows.
Calculate & validate
Confirm the relationships before export
Use focused calculators to review open area, pitch, bridge width, and ventilation inputs.
Open Area Calculator
