I have tried out KiCad for a while now and like the uncluttered interface and intuitive navigation, and am almost at the point of switching to it for all my PCB work.
However, as far as I can see, there's a stumbling block for me: I can't seem find a way to produce curved tracks. Graphic curves can be placed on any layer except copper, seemingly. There are other microwave features that seem quite useful, but curves and circles would be even better. In one of the demo PCBs (microwave.brd) that come in the installation, there is a rather impressive curvy shape that appears to have been drawn in the module editor. <...20mins later> I have now figured out how it is pasted as text into the module definition. I'll work on that... Can anyone help regarding the curved tracks, though? Is the text file import the only way? Regards, Tony
