Creating new circular component like a valve base

    Hi Kevin, good question. There is no direct command I am aware of but I'm always willing to learn :)

    My method is to create a template on the documentation layer.

    Place the relative origin and draw a circle of the required radius for the pads from this. You can customise the circle after selecting from the tools, right click and select define from the center, you can also enter the radius. Change the layer to documentation (or silksreen) as you can delete the template when complete.

    Now draw some horizontal lines greater than the radius of the circle on the documentation layer using the open shape from tools. If you right click on a selected line there is an option to rotate by an angle, then place the line from the relative origin and complete the template.

    Now place the pads on the intersections, set the grid to say 1/40th and zoom in to place.

    I did something like this for the mounting holes on a PCB, but the above images are from the footprint editor.

    Hope this helps.

    There is a Valve library available from a user here (but note you said 'similar to a valve'), but may be useful to others..

    Thank you. Problem solved and component designed. The actual component was a vacuum fluorescent display type IV-12 in my design for a digital clock.
