It can be tricky getting used to changing your view, or "Moving Around" in Anim8or's virtual space. Here are some tips:
1. Max out your screen
IF you're having trouble grabbing ahold of objects, make sure your screen is MAXIMIZED on your monitor - it will make the interface easier to deal with.
2. Zoom in with "F"
Hitt the F key on the keyboard to FILL the screen - zooming in or out to show any and all objects in your 3D "Universe"
Hitting SHIFT-F will zoom in or out only on SELECTED elements
Try selecting only the DOME of the saucer and SHIFT-F to zoom in on it. Hit F again to show the complete saucer
3. ARC-ROTATE with CTRL-R (or hold the ALT key)
Arc Rotate changes ONLY YOUR VIEW - not the actual angle of any object. You know it's on when you can see a green "Targeting Reticle" (A circle with handles on it) superimposed on your screen - learn to turn it on and off quickly, and your'll REALLY speed up your model development - it's one of the HANDIEST tricks you can learn in Anim8or!)
ROTATE around your object using the LEFT Mousebutton - INSIDE the circular reticle
TILT around the Z-axis using the LEFTMousebutton - OUTSIDE the circular reticle
STRAFE left right up or down using the RIGHT Mousebutton - INSIDE the circular reticle
MOVE IN using the MIDDLE Mousebutton - INSIDE the circular reticle (Very Useful!)
4. Turn on QUAD View
Hit the DEL key in the bottom right corner of your keyboard
Choose your VIEWS
Click one of the four sub-windows and try each of the four buttons on your numeric keypad to select an isometric view:
[5] FRONT VIEW - start here - it's the middle of your keypad, and the most useful view
[4] and [6] are LEFT and RIGHT
[8] and [2] are TOP and BOTTOM
[7] is BACK
[9] and [3] are ORTHO and PERSPECTIVE
[1] Does nothing :^(
