move a line in a circle and keep one end stationary

[alpope]

I want to depict an airplane flying in a horizontal circle with a line from
the airplane stationary on one spot on the ground in PPT 2003. Any ideas?
In other words the airplane would be tied with a line to a spot on the ground.

This is a simplifies version of the technique that Glen Millar taught to us,
now we can teach it to you.

A non-centered pivot point can be achieved by grouping an object with a
mirror image that is hidden (100% transparent). So in your case, copy your
line from the plane to the pivot and paste a duplicate on the other side of
the pivot. Make sure the line is the same length and exactly opposite its
mirror. Now apply the line color "No Line": note that the line disappears,
but the end points remain visible. Now you will want to group these two
lines together. When you apply the spin animation (PPT 2002+) the line will
appear to spin on its end (only you need to know that it is spinning around
the center of a half hidden shape).

Bill,
Thanks. That works in the vertical plane, but I want to depict this in a
horizontal plane. Is there any way to achieve the spin effect horizontally
instead of vertically? In other words, the spin effect moves like the face
of a clock. I want it to move in a horizontal circle.

 

[Bill Dilworth]

If you want to look at the clock from the edge instead of from the
'overview',the animation gets real tricky and still does not produce a good
effect.

You will need to apply multiple animation techniques to move the airplane
back and forth, while making it grow and shrink, while moving it up and
down. Then, if you want the airplane to appear to be flying forward on the
back half of the oval ... yuck!! It would be complicated, unreliable, and
ugly: don't waste your time on it. You would be better off using a 3D
rendering program to create a movie of an airplane flying in an oval and
looping the movie.
