Gentlemen, thankyou for your help.

Now I can get a realistic viewing angle and it does do what it says on the tin (almost). Using the mouse to change viewing angle causes the viewpoint to move also, which is unhelpful. Simply typing the angle, though, works a treat.

Thanks again

Am I missunderstanding something? I hadn't seen that control before, but it doesn't do anything different for Zooming? I want to be able to expand the angle of view, but not change the distance I am from the point I'm looking at. All Zoom seems to do (and Field of View) is to move toward or away from point of interest. In many respects Field of View and Zooming would be similar, but with zooming I often find myself backing out through walls etc, if I was changing the field f view that couldn't happen?

apologies for being confused.

Regards

My only frustration with SU is the viewing angle when in walkabout. It would be really useful if the viewing angle could be adjusted to what I can see with my eye (including some peripheral vision) and not just what a 55mm camera lens shows!. Zooming isn't the answer (or doesnt seem to be) as it merely drives me back out through the wall!

Great free software though - it actually does something useful!

Regards
