I have a model of a spring, variable pitch, using Pitch and Revolution. I am trying to configure it for different compressed lengths. I created a configuration for the compressed length, click on the Helix/Spiral in the feature manager, right click on one of the pitch values, click on Configure Feature, and change the value in the table. But the problem is it also changes the revolution value in the default configuration. Can't see what I'm doing wrong.
Thanks Paul

I'm not sure what options were available in 2009 for the helix, but if you can, try changing the base definition type from "pitch and revolution" to "height and revolution". with the former setting it is keeping the same pitch as the original, but with the changed height, the # of revolutions change.
