Create polylines spaced by the same amount of distance

Hi

I'd like to create a set of identical polylines parellel to each other and with the same spacing between each other. Is there a command that allows to do this?

Alternatively, is there a quick way to do this without having to measure the distance between every single line? I know I can draw two lines that have the required spacing and then select, copy and paste them beside each other, but I'd still have to make sure that the new set of pasted lines are at the required distance....which can be cumbersome if there are many such lines to draw.

Best regards
