Making a Cutting Template


In order to create a cutting template for lasercutting, the screen design has to be transformed into a useable format. Most shops can accept a 2D DXF or AutoCad drawing which outlines the pieces to be cut as continuous closed shapes, also known as closed polylines.

The following example from Greg Thomson's design shows the process starting with a 2D drawing.

From the original drawing, trace over or separate the shapes to be cut or engraved onto separate layers. Pull apart overlapping pieces.

Pattern pieces repacked.

Once the pieces are created, scale them and pack them tightly to fit the material, adding some spare pieces with the remaining material. For transmission, the template file can have only one repetition of each piece. Save the file as a DXF or AutoCad drawing and post on the web.

Below is another example showing how Katina Duttton's screen was repacked for a closer fit. The square voids are temporarily lost so that each cut is as efficient as possible.
