Imagine a flower bud that I need to show going from the closed stage all the way through to the open flower stage.
I have created a model using dimensioned lofted "petals" and guide curves, and then trying to come up with dimensional steps to make a stop motion kind of animation, but I need this to look smooth and clean.
if yo take the drive curve of the loft say for axample a spline you can drive it from an assembly and hide the drive key or the item you would set as a path point this would in effect drag your curve so it would look as if the petal was altering shape
Yep, I was able to make an animation out of it in a matter of minutes using one simple equation...

's_animated_garden.zip What's so cool about using equations is that you can drag and drop as many parts into an assembly as you want and they all animate together. No need to set up a bunch of freakin paths.
*) Download and open Paul's file
*) Swith to the first configuration (closed)
*) Edit "Sketch3"
You will see the diameter dimension .100. This is the dimension you want to drive with an equation.
*) Create a new equation and select the "Add" button
*) Select the .100 dim and create an equation similar to this...
"D1@Sketch3"="D1@Sketch3"+.1
*) Exit the sketch and hit "Rebuild" several times.
You will see the petals begin to slowly open. Each time your rebuild, the flower grows.
With Animator, you simply enable Screen Capture and keep hitting rebuild until you are satisfied with the results. The resulting AVI file will play just like mine.
You don't even need animator if you've been keeping up with the newsgroup. There are methods others have on their websites to do this with free utilities.
Now, what I like to do is use a simple macro that automates the rebuilding process. I just type in the number of rebuilds I want and it does the rest.
If you want to get clever and have the flower stop growing or close back up, you can use the IIF statement in your equations to do all kinds of automated things.
If you drop Paul's part into an assembly and create your equation there, each time you drop another flower in your assembly, it will automatically animate.
If you drop a sub assembly into a top assembly and pattern it, you can animate an entire feild.
