Structures
Set up your model and run a structural analysis or optimization.
Model Setup
Create connections and apply loads, constraints, materials, and manufacturing controls to your model.
Manufacturing Controls
Apply manufacturing constraints using shape controls and bead patterns.
Shape Controls
Use the Shape Controls to apply optional constraints to your model such as draw directions or symmetry.
Draw Directions
Draw directions are used to ensure that a design space can be physically manufactured using a specific process such as casting, stamping, or extrusion.
Extrusion
Extrusion is a type of manufacturing constraint. It is similar to a single draw constraint, but the profile of the resulting shape maintains a constant cross-section along the draw direction.

- Model Setup
  Create connections and apply loads, constraints, materials, and manufacturing controls to your model.
  - Connections
    Create and define connections such as fasteners, joints, connectors, spot welds, and contacts.
  - Loads and Constraints
    Apply loads and supports, displacements, accelerations, gravity, temperatures, and center of gravity.
  - Materials and Libraries
    Create materials, assign materials to parts, and organize them into libraries.
  - Concentrated Masses
    Use the Masses tool to create a concentrated mass either on a part or at a point in space.
  - Systems
    Use the Systems tool to create and apply user-defined coordinate systems to loads, supports, and displacements.
  - Manufacturing Controls
    Apply manufacturing constraints using shape controls and bead patterns.
    - Shape Controls
      Use the Shape Controls to apply optional constraints to your model such as draw directions or symmetry.
      - Draw Directions
        Draw directions are used to ensure that a design space can be physically manufactured using a specific process such as casting, stamping, or extrusion.
        Single Draw
        A single draw direction is a type of manufacturing constraint, and is used when the parting plane between the halves of the mold lies outside the design space.
        Split Draw
        A split draw direction is a type of manufacturing constraint, and is used when the parting plane between the halves of the mold lies inside the design space.
        Radial
        A radial draw direction is a type of manufacturing constraint. It is used when a machining tool needs to enter in a radial direction toward the center of the plane.
        Stamping
        A stamping constraint should be used when the manufacturing process calls for stamping rather than casting.
        Extrusion
        Extrusion is a type of manufacturing constraint. It is similar to a single draw constraint, but the profile of the resulting shape maintains a constant cross-section along the draw direction.
        Overhang
        Overhang is a type of constraint used in additive layer manufacturing. It is used to eliminate overhang and create a more self-supporting structure, which helps minimize the need to add support structures when printing your part.
        Milling
        Apply a 5-axis milling constraint when a 5-axis milling machine will be used.
        Obstacles
        Designate parts as obstacles when applying a single, split, or radial draw direction.
      - Symmetry and Cyclic Repetition
        Symmetry and cyclic repetition are used to create optimized shapes with repeating patterns and/or nearly symmetric results.
      - List Shape Controls
        Use the Shape Controls table to view and manage shape controls that have been applied to your model.
    - Bead Patterns
      Beads are used to help meet specific design requirements such as stiffness when running a topography optimization on a surface.
  - Mesh Controls
    Use mesh controls to assign an element size to parts or faces.
  - Temperatures
    Use the Temperature tool to simulate the effects of temperature changes on your model.
  - Center of Gravity (COG)
    Use the Center of Gravity Constraint (COG) tool to apply, reposition, and set upper and lower bounds for a center of gravity constraint. COG constraints are used to limit the position of the center of gravity while running a topology optimization.
  - Gravity
    Use the Gravity tool to apply gravitational acceleration (G) and adjust its direction.

Extrusion

Extrusion is a type of manufacturing constraint. It is similar to a single draw constraint, but the profile of the resulting shape maintains a constant cross-section along the draw direction.

Due to the nature of the extrusion process, there will always be a hole in extruded parts, so the No Hole option in the microdialog is not available. Extrusion constraints are valid for optimization but not analysis.

Apply an Extrusion Constraint

Select the Extrusion tool and click on a design space to apply an extrusion constraint.

On the Structure ribbon, select the Draw Direction tool on the Shape Controls icon.

Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
Click the Extrusion tool on the secondary ribbon.
Click on a design space to apply an extrusion constraint.
A microdialog appears, along with a set of three orthogonal planes. The active plane is shown in blue.
Select a plane to orient the extrusion draw direction.
Right-click and mouse through the check mark to exit, or double-right-click.

Tip: You can also right-click on a design space in the modeling window or in the Model Browser and choose Shape Controls > Extrusion from the context menu.
