When I open a layout tab, the paper space units are always in inches even though all my other units are in metric.
This makes it difficult to scale the viewport as the simple 1/200, 5XP etc do not work correctly. You have to convert the ratio to a metric part of an inch to get a correct scale. e.g. To zoom the layout to a scale of say 1:200 you have to zoom to 39.370" (1m) / 200m = 0.19685XP.
I then have to use a plot scale of 1" to 1 unit. It works but its not ideal.
Neither "Help" or my AutoCAD handbook cover this situation. Typical examples always have the same type of unit in both spaces.
My .dwt is metric and my default plot device has a metric paper size.
Where is the layout getting its units from and how do I change the paper size units to mm?
