How do Driving Dimensions work?
Your model is updated automatically to satisfy simultaneously all your Driving Dimensions set to its elements in the following cases: • once you create a new Driving Dimension (using the Driving Dimension tool from the Driving Dimensions toolbar) • once you edit the value of any Driving Dimension (selecting the Driving Dimension tool and double-clicking on existing Driving Dimension) • once you select the Update Geometry command from the Driving Dimensions toolbar (usually users do that after they move or resize some entities so that some Driving Dimensions become violated and displayed in red color) Please note that you can change this default behavior by switching different LDD options.
