Hi,
I've created a component (NOKIA 5110 display) with a size of 45.72mmx48.26mm in the PCB Lib. When I place this on a PCB the size changes to 1780mmx1850mm. Seems like some sort of mm to inches conversion ... but I can't see what I'm doing wrong.
Here is the lib on the left and the pcb on the right:
I don't know if it's deliberate to avoid such confusion but in the UK, all our technical stuff is in metric usnits but if we still need to refer to small imperial measurments, we use the traditional "thou" rather than "mil".
:)
It is a bit confusing initially ... 'thou' would have worked for me (as I'm in Ireland) ... anyway, thanks, I suppose I would have figured it out eventually, but your help certainly saved me some head-scratching!
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Look at the Units on the two screenshots.
The left one is in millimetres (mm).
The right one is in 0.001 inch (mil or thou).
:)
