Hi Folks,  I have generated a huge number of files each with a similar 3D rendering that changes dimension only slightly from each file to the next.  What I am trying to do is establish a consistent camera angle for all the files.  Unfortunately, I am having quite a bit of trouble with establishing a camera angle manually with all the choices in DVIEW.   I have my lights set up the way I want, and the perspective is great, but I hit a brick wall when attempting to establishing an exact camera view.  My object never quite seems to stand upright.  I place the lower left corner of my object at 0,0,0 and make that my target.  I set the camera somewhere to the upper right with an x,y,z coordinate.  But the object then flips in ways that seem irrational.  Any guidance will be much appreciated. 
All the best,
Eric
