How to change the measurement unit from "mils" to "mm" in Allegro Free Physical Viewer (version 17.4)

ChrisKlingner

Hi,

I'm using Allegro Free Physical Viewer (version 17.4) to view board layouts.

By default, the coordinates on the bottom show with a unit of "mils". Could you please tell me how to change that to "mm"?

Thanks!

Chris

    Switch to using the allegro_free_viewer_classic instead of the new brain-dead allegro_free_viewer

    Hi David,

    Thanks for your response. Could you please tell me how to get that viewer? I've checked the CDS download site and only these 3 versions are available:

    I currently use the first one. I suspect I can't use the last one as I don't have those Windows versions. (Ideally, all those ran on Linux.)
    Thanks,
    Chris

    There doesn't appear to be any way of changing the design units in any of the free viewers, they will only use the unit from the last time the design was saved Disappointed

    I have the licensed version & after they released the new crippled 'allegro_free_viewer' I noticed the other 'allegro_free_viewer_classic' binary  in the s/w tree
