To keep it simple, I want to "slowly" show a pin move into a hole. I have a configuration called "out" that has a distance mate that puts the pin completley out of the hole. I have another configuration called "in" that has a coincident mate that puts the pin completly in the hole. At 0 seconds I would like to see "out" and at 4 seconds I would like to see "in". And of course, see the pin move from "out" to "in" over the 4 seconds of time.

The best I can do is to get it to jump from one configuration to the other with no visual movement in between.

Thanks in advance-
