Question

Controlling/Constraining Explode Animation Part-Paths

I've got a complex assembly I cannot share directly, and I am trying to animate the actuation of the mechanism for a presentation.

I am using explode states to add in/replace parts and actuate them as I'm not aware of a method for moving the mechanism to various pre-defined positions within the assembly constraints (which would be really nice, and I'm surprised if it is not an option)

 

When trying to animate the opening of a door with an explode rotation, the path of the part as it transitions from state 1 to state 2 is not a simple pivot, but rather some eliptical mess.

Is there:

- A way to constrain movement between explode states?

- A way to animate using various positions of objects related using assembly constraints (pin, slot, slider, etc)?

 

Much thanks in advance for the insight.

Dave

Creo mechanism supports animation of kinematic constraints. You will need to define valid kinematic chains and then drive the mechanism with a motor. You can then generate an animation of the actuation.

Is it possible to combine the kinematic animations with explode state animations?

e.g.

- remove car engine in isometric view    (explode)

- replace with new engine isometric view    (explode)

- install hood during pan to elevation view    (explode)

- hinge it hood closed in elevation view    (mechanism)

 

Thanks for the quick response!

I have never combined animated explode states with mechanism animation, but I know you can use simplified reps in mechanism animations. It seems like the simplified reps would take care of your listed examples. You may not have the "animation" of transitions between explode states but can create video of the mechanisms moving in each rep.

 

Are you attempting to make one continuous video without cuts the makes all of the movement and configuration changes?
