Locking Ortho Views, plz help

I’m a maya trained individual, but i’m trying to expand my knowledge of progs.
so… i’ve figured out how to import images into a view plane to use as refrence, however if i accidently move the camera blender will pop out of Ortho and go into Perspective view. How do i force a viewport to STAY locked till i say otherwise?

i’m useing a maya like setup 4 views

1: UV 2: Perspective
3:Left 4:Front
and the outliner on the far right

how i set up the refrence images (just to be as thuro as possible)

(N) to bring up the option panel
(check) Background images
add image (front.jpg)
view Front num pad 1
num pad 5 to set to Ortho mode

its set now just like i like, -minus it poping out of ortho :frowning:

If it pops out, just hit Num pad 5, right? I don’t work with 4 views showing all the time. But when ever I go into Camera view / Perspective view, I need to reset the screen to Ortho.

In the display tab (one of the ‘N’ key options) click the “Toggle Quad View” button. This displays a top, front, and right ortho view that you can’t take out of ortho view (though you can pan and zoom). The fourth window is a standard blender 3d window where you can switch between ortho and perspective, camera view, etc.

awesome thx, yes i still want pan & zoom, just not rotation.
