I have come from an AutoCAD background. When i set up a drawing and set the viewport scale, i can use zoom 1/1000xp to get my drawing displaying at 1:1000 scale on my page. I have discovered that in Map 3D, there is this issue i am having where by if i scale my viewport the same way, zoom 1/1000xp my image is too small for the page and to get it to actually scale at 1/1000, i must zoom 1/1xp. At the bottom of my screen on the tray next to the maximise viewport button is the 'scale factor' which indicates 1:1000. I imagine this has something to do with the fact that when i scale my VP to 1:1, it displays at 1:1000. And when i wish to show 1:500 scale, i will have to scale my VP to 1/2xp. HOW do i change the default scale factor from 1:1000 to 1:1 as it is in AutoCAD?
