I'm using a trial on Altium, where for I guess support ignores me (Altium Designer version 19.0.14).
(I really hope it's better for real users if someone can confirm that, it would be most appreciated)
Back to the question: I want to change all the mils units to metrics.
I found this guide:
https://resources.altium.com/pcb-design-blog/menu-changes-and-switching-units-in-altium-designer-18
However, it doesn't seem to work. If I change the primitive to "MMs" I can't apply them unless I do some other changes as well, however, the settings won't apply anyway, it's still stuck with Mils.
Is Altium like this or can it be changed?
