EFA CAMverse › GenCAD viewer
Unique GenCAD from 7 formats – for the test field and EFA SmartSuite → Format guide · GenCAD 1.4Received a .cad file for assembly or test? EFA CAMverse opens GenCAD 1.4 natively – no cloud upload – and shows board, components, netlist, panels and 3D. And in the other direction it generates GenCAD from 7 of the 9 supported formats – for programming your test equipment and the handover to EFA SmartSuite.
GenCAD 1.4 – the ASCII link between CAD layout and assembly/test.
GenCAD is a well-readable ASCII format that describes a PCB assembly for placement and test: board outline, pads and padstacks, component shapes, placements, netlist and mechanical holes – organised in named sections ($BOARD, $PADS, $SHAPES, $COMPONENTS, $SIGNALS …).
GenCAD was developed by Mitron and established itself as the practical link between CAD layout and manufacturing or test equipment. Version 1.4 is the widespread, de-facto authoritative release – the format has remained stable over the years.
Download for free and install – a native Windows application (10/11, 64-bit), free to use as a viewer.
Open the GenCAD file directly – panel files with multiple individual boards are displayed as well, each board at its position.
Toggle layers, highlight nets with a double-click, inspect components, measure distances – and switch to the 3D view with one click.
Toggle every layer and view the layer sequence in the stackup pane.
The netlist ($SIGNALS) – with bidirectional highlighting by double-click.
All component placements with reference, device and every attribute – for bill of materials, quotation and assembly print.

Panel files with multiple individual boards are displayed – each board at its position within the panel.
Precise distance and geometry measurement right in the layer view.
Output or print the view as PDF, PNG or JPG – for documentation and coordination.
A native Windows application – no cloud, no upload. Your manufacturing data stays on your machine.
In-circuit testers, flying probe and AOI systems in the test field – as well as placement machines – are often programmed with GenCAD. Whether your customer sends Gerber, ODB++, IPC-2581 or a CAD project, EFA CAMverse creates the matching GenCAD file from it: real conversion, not just viewing.
GenCAD 1.4.cadTogether with EFA SmartSuite, EFA CAMverse turns the GenCAD file into a fully set-up EFA project – the way to automated inspection of the board shrinks to a few steps.
With GenCAD: the components of both sides are already in the file – no coordinate file needed.

What is GenCAD used for?Mainly for programming placement and test equipment: SMT placement machines, in-circuit testers (ICT), flying-probe testers and AOI systems. Because component positions, pad geometries and the electrical netlist come together, placement and test programs can be derived from it – and the plain ASCII format is easy to generate, read and verify.
GenCAD vs. Gerber & ODB++GenCAD focuses on assembly and test (components, pads, nets) – not on full layer fabrication like Gerber or ODB++. It typically carries no detailed material stackup. That makes GenCAD complementary to the fabrication formats – EFA CAMverse connects both worlds. To the Gerber guide →
And when the next customer delivers something else: EFA CAMverse also opens 8 more PCB/CAM formats – in the same tool, with the same way of working.
