Manipulating the axis of a 2D graphic
I have made a flat 2D design in Illustrator that I want to change the viewer's perspective on. So where it is currently being viewed head-on or top-down, I'd like to skew the projected viewing angle to something less than 90 degrees (and off to a side while I'm at it).
Is this possible in Illustrator or do I need to use a 3D tool (and presumably, convert the logo to a 3D model)?
It really all depends upon the art.
You could use
Effect > 3D > Extrude & Bevel
Effect > 3D> Rotate
You could use Illustrator's Perspective Grid to snap object to a perspective plane.
You could use the Free Transform Tool, click a corner then hold down Command+Option+Shift (Mac) or Ctrl+Alt+Shift (Win) then drag. Note; You MUST click and hold a handle, THEN hold down the modifier keys.
