ZofzPCB 3D Gerbers and Drills View

ZofzPCB 3D Gerber Viewer Gerber Viewer in 3D

The free part of the freemium.

What is the difference, beside the 3D-iness?

Missing Information

In 2D Gerber viewer you load gerbers and maybe also drills, in any order. They will have assigned arbitrary colors, to distinguish them. Possibly you can also rotate the z-order, bringing to front the layer you are interested in, at the moment.

To construct a 3D model, the viewer needs to know much more. As the abstract thought and knowledge of a CAM operator is hard to program, the user have to add or correct the missing information:

ZofzPCB tries to retrieve or guess this information, sometimes incorrectly. Therefore, it is always possible to correct the "Auto" loaded data, before rendering. It is a good practice to save the configuration in the .camset file. It will be easier to load the files, next time, after editing.


We are using a game engine to display the image. Drawn/painted layer contains many overlapped objects. Often a part of the image is cleared, and some other elements are drawn in the resulting hole, example: like track in a plane. All this higher level construct must be converted to optimal positive mesh. The result is that even a complicated PCB can be displayed by moderate GPU, usually at 60fps.

Drawback of the flattening and triangulation is the time it takes, before passing the mesh to the GPU.
