Can I create a configuration of my model using the rollback bar to remove some features from my model?
SolidWorks configurations do not currently recognize the rollback bar as a means for removing features from a configuration. The features need to be removed by suppressing them. One way to suppress a feature or features is to select the feature or features to be suppressed then choose Edit - Suppress - This Configuration. Note that you can use a Shift-select in the FeatureManager to select all the features at the end of the tree for suppression, to mimic the effect of the Rollback bar.
