    techniques are stored as parametric features

    Obey all standard parametric feature rules

    Part design requirements have evolved, new control required

    Why rebuild if you can assign new design intent instead?

    > Dragger Collectors Origin collector remembered position of the

    dragger Orientation collector allows separate

    orientation of the dragger Dragger positions allow reproducible

    regeneration of the feature Note: Free move uses no collectors only the

    final geometry location is stored.

    Special Collector for Moving Curves and

    Datums with the Geometry Set

    > Keep Original: Keeps original geometry in original

    location; makes a copy

    > Excluded Surfaces Collector Allows the use of advanced selection

    techniques to exclude surfaces from the selection set.

    > Move Any Number of Surfaces Move surfaces via multiple, recorded

    steps Define dragger placement & orientation Define step size

    Move with no steps: Free Move Only final position is recorded

    Apply simple dimensioning scheme

    3 Translations, OR 1 Rotation

    > Parameterize Imported Models Apply parametric control to key surfaces Enable design studies Develop families of imported models

    > Re-Parameterize Existing Models Define new design intent on older models Explore what-if scenarios not possible

    with existing design intent

    Move & Move by Dimension

  • 47

    > Position Geometry using Assembly

    Constraints Works well in combination with Free Move

    Position geometry approximately first

    Then use constraints to finalize position

    Standard constraint types available.

    Distance constraints result in parametric dimensions

    > Maintain Solution Topology Controls how the system reacts to changes in topology around the flex

    move feature.

    When checked, the system will fail the feature if the system cannot apply the remembered solution because of a topology change

    When un-checked, the system try to apply the remembered solution, but switch to the first found default solution if possible.

    sets Leave open removes the selected surfaces and does not extend

    adjacent surfaces to close. New Quilt when working with surfaces, this option creates a new

    quilt from the extended geometry Surface when working with solids, this option creates the surface
