Compression spring model? SW2006

I have looked for this answer a few times and have not got a clear answer.

I would like to place a spring into a model and have it update changing the pitch of the spring. The closest thread I came across was thread559-139236. The last post was that he found a compressible spring model?

I have a spring modeled but when I move parts the spring is not moving "compressing." I am not aware if there is a mate for this?

Thanks..[thumbsup]

There's no way to create a single part model such that it updates dynamically while dragging other components in an assembly. You can use equations and in-context references to create a model that updates when you rebuild after dragging other components.

I interpret the last post in the thread you referenced to mean that the person finally figured out how to create his model per the instructions in the replies.
 
I notice in 2006 (not sure which SP) there is a Spring function. I don't have it in front of me but it is in the same section as gravity and the other simulation tools.
 
from the help:
To add a spring:

1) Click Linear Spring on the Simulation toolbar, or click Insert, Simulation, Linear Spring. The Linear Spring PropertyManager appears.

2) Select two Spring Endpoints to connect the spring. You can select linear edges, vertices, or sketch points.

If you select an edge, the Spring Endpoint attaches to the midpoint of the edge.

3) Type a value for Free Length to determine if the spring is stretched or compressed.

4) Type a value for Spring Constant to determine the strength of the spring.

5) Click OK.

A LinearSpring icon is added to the FeatureManager design tree under the Simulation icon.

You can set it up so that if you move one component, or change a mate, the spring will update at the next rebuild.

To do this, write an equation that sets D3@helix = (some dimension which is the total height of the helix.

The helix should be made using height and revolutions if you want the pitch to update.

The "spring" these other fellows are talking about is just a way to apply a force or limit motion in the Simulation functions, not a graphical geometrical spring.
