A driven dimension does not change — gull system Handbook

A dimension gull system drives does not change in the model when it is set for one configuration only. Why it happens and how to set it for all configurations.

A driven dimension does not change: set it for all configurations

A model whose configurations you do not drive, but whose dimension you do: the order runs without an error and the part stays the same. The usual cause is a dimension set for one configuration only.

Why it happens

A dimension can have a different value in each configuration of a part. For now gull system writes it into the part’s active configuration — which need not be the one the assembly uses. The value then changes in a configuration nobody sees, and nothing happens in the model.

How to set it

1. In SOLIDWORKS, open the part with the dimension gull system drives.
2. Double-click the dimension to open the dialog for editing its value.
3. In the configurations drop-down, choose All configurations and confirm.
4. Save the part. From then on the dimension changes whichever configuration the assembly uses.

This concerns only dimensions gull system drives. A dimension that is meant to differ between configurations is a sign you should drive the configuration choice instead of the dimension.
