Upon further investigation, i have found the answer. Ruby script named simply "camera parameters". Essentially, you pick a viewing point with PositionCamera tool, set the HeightOffset to 0 (zero), and direct the view to wherever you want. Then you click on Camera menu above the toolbar, at the bottom of the drop menu should be Camera/Mire and Camera/Azimuth/Elevation, if you installed the ruby script correctly. Click on Cam/Azi/Ele and choose your parameters. Azimuth translates/rotates your view left or right, and elevation lowers or raises the view. If looking left, the azimuth will be negative regarding the axis you are facing. If looking down, elevation will also be negative regarding the same axis. AngleFocal in this menu is basically the angle of viewing. For example, if the CCTV camera has a 2,8mm lens coupled with a 1/3" chip, the angle should be around 90°; if the lens is 2,8mm with 1/4" chip, angle will be narrower, between 60 and 70°.

There. Hope this helps anyone else, besides myself.
Cheers!

@mr. Gaieus, your answers are very much appreciated! Thanks!

Hi, guys! It's been some time since my last visit , but i need some help. I work for a small firm that specialises in security systems, video surveillance systems etc. I was wondering, has anyone found a ruby script or a trick on how to view models from a CCTV camera point of view? To explain myself; i need to make a simple model of a house with some courtyard around it. Some trees, bushes, you name it. Place a view point on a corner of the house, wall, fence etc. Is it possible to change the "zoom ratio"? As you probably know, there are cameras with varifocal lenses, which means that the width and zoom can be changed freely. I need to do that, in regard to the scene/frame i am viewing. For example, place the camera ~3.5m high, looking towards one corner of the yard. How could i show my customer what he can see with one lens type, and then the difference with another lens?

I tried to explain to the best of my abilities, but english is not exactly my native language. Any help is very much appreciated.
Thanks!

thanks for all the help!
one more thing is very interesting to me: SU physics. i would like to make a model with moving parts, hinges etc. any advices?

i got it right, finally:) thanks, again!

i did it like that exactly, but i obviously got it wrong somewhere. when i used move on the top lines, a part of the small plane on the outside rim of the tooth was erasde. i'll just keep trying:)
Thanks again for the help!

this looks great. how did you apply the tapers? i can't really tell from the pics. Thanks!

thanks for all the help, guys! i made a model of my screwplate, i'll post it here so someone else can use it. one more question, how can i taper the top of the gears? i tried a bunch of plugins, but none of it seemed to work for me.
anyways, thanks for the help!

simple gear+helix screwplate.skp

not sure if i made a mistake somewhere, or posts need to be approved
anyways, thanks for a quick reply, You helped A LOT. if you can help me with one more thing: other side of the plate: how do i make a pattern like this? this is, essentially, a number of lines (extrusions) spread evenly over the circle, or the rim, not sure how to describe it (pic will say more).
thanks again!

wow, that was fast. thanks for your reply! another thing, if i may bother you a bit further, how do i make the other side? other side needs to be like a horizontal screw, essentially lines (teeth) spread across the circle in an equal manner, if you understand me.
thanks again for your help!
