Orbit CAD views

The orbit for changing your CAD view is located in the top right-hand corner of your drawing.

You can switch directly between the Top, Bottom, Front, Left, Right or one of the North, South, West or East views by clicking the mouse.

If you hold down the mouse button and drag the cursor over the orbit in the horizontal direction, the image section moves parallel to the XY plane of the world coordinate system (WKS). However, if you drag the cursor vertically, the image section changes along the Z axis.
