| # Linking Constraints by Family Feature For each family aspect you can define a constraint. By using a constraint you can exclude values of the aspect that depend on the values of preceding aspects in the classification code. This procedure results in a family-dependent constraint, as the sequence of features in the classification code can differ by family. You cannot assign a constraint to the first aspect of a family, because in that case there is no predecessor aspect. Start the Constraints (tigrt0137m000) session from the appropriate menu to display the constraints. Note If you have started this session by zooming, you can only find and select a record.
