Anyone have any ideas on how to create these? What I want is a Front, Top, Left(or Right) viewport system for an editor im working on. Any help would be appreciated :)

Define a viewport, rotate and position the camera, possibly use Ortho mode or just a high zoom if you want to remove perspective, and render it with wireframe mode enabled.

Well, more specifially I would think you define each viewport at say 0,0 with a width/height of 200,200 (example) hide all cameras, show one, render, copyrect to a image buffer, hide, show next, render, copyrect, etc, etc At the end just draw all four images to the screen where you want the viewports visible.

Well yes, if you want to move the viewports partially off screen in a windows type way, otherwise you might just as well render each one directly where you want it with far less overhead.

Create 3 cameras, set their viewpoints to a quarter of the screen size, and position accordingly. Place one above the object, one to the side and one in front of the object. Point all cameras at the object. Hide all cameras save for one Render wireframe Hide the camera and show another one and render again hide this camera and show the final one.
