[Mark Young] "Unfortunately the effect I'm looking for doesn't work with a camera (or no camera) in the comp. I want to get a render that has no perspective (as if you were looking at a front elevation on a blueprint)."
You can't render the Front view. You can, however, create a camera with a ridiculously long focal length (zoom) that would almost eliminate perspective. You could link the camera's Z position to its zoom:
x = thisComp.width / 2;
y = thisComp.height / 2;
z = -cameraOption.zoom;
[x,y,z]
Then keep increasing the zoom value until it looks close enough... or AE crashes (;
