I had a few issues with some vias, but it was easy enough to fix. I have used it before and gotten acceptable results. There is also a format converter for kicad that allows you to import Altium designs into KiCad.

I also have not looked into it that much but one of the focus areas for KiCad 6 is the netclass rules system, so it should be pretty close to feature parity by then. Its not much of an issue for embedded systems. The net class rules system in Altium allows you to more easily set clearance rules between different nets and is useful for things like power electronics, when you have a set of nets that can gave traces close to each other but far away from the ground plane. KiCad keeps improving, but with KiCad 5 the biggest disparities between KiCad and Altium is the ability to check 3d component clearances with an enclosure in real time and the net class rules system. KiCad also seems to have a lot less perplexing errors. I find the KiCad interface a lot more responsive and find the UI more intuitive. I have done work commercially in both Altium and KiCad and use KiCad for personal projects. Individual colors for single objects like lines.A GND symbol with multiple horizontal lines arranged as a triangle.Bezier curves for component symbols -> WONTFIX -> Workaround with linearization.Design Rule Check settings are not converted.If this converter does not work for your files, feel free to provide your files and screenshots of how they do look like and how they should look like, and I will try to help.

Please verify the output of the converter kicad_pcb files)ĭue to the huge differences between Altium and KiCad, the weak fileformat documentation and the high complexity of the fileformats, this converter cannot guarantee the quality of the conversion.

(it converts the schematics from the subdirectories to.

If the Altium design contains 3D models in step format, run kicadd_oce_vis or step2wrl or FreeCAD to convert the files to wrl (with FreeCAD open and execute the macro step2wrl.FCMacro ).
