Change Radius of Arc

[savaytse66]

For simplicity sake, lets say I have a simple block consisting of an arc. It's a simple arc that looks like a rainbow; the start and end points are at the same Y-coordinate. I want two dynamic options. The first would be to make the arc wider or narrower, which is simple using a stretch action. But I also want to be able to change the radius if my start and end coordinates do not change.

In other words, if I just had an arc that wasn't a block, I could activate the midpoint grip and drag it so my radius changes, but my endpoints don't. I want to do this in the context of a dynamic block. Obviously, my block is more complex than just a standard arc.

Any ideas?

Thanks,
Chris

i haven't played in 2009 yet, but as of yet, you can't manipulate arcs (with the grips) in DB's

...Well not easily ;)

Try scaling the arc and chaining to linear params with negetive stretches to keep the start and end points in the same place. It can be done but i think the block has to be reset if the arc is to be changed again once it has been moved once :|
