hi,
you may need to use 'align view' and 'solar north' to switch between two [or more] 'modeling axis'
if you use solar north on an empty drawing you'll see it follows the green. if you draw a plane ['rectangle tool'] at origin it follows the red/green axis's, if you then rotate the face 45° >>right click the face >> select 'change axis', any new geometry, groups or components will use that axis orientation. Now rotate you face back to solar north >>right click the face >> select 'change axis', and any thing you draw will be at that axis....
