Apply Constraints

Apply pin, blankholder and drawbead contraints.

Add/Edit Pin Constraints

Apply Pin constraints to the points and edges of a part.

  1. From the Feasibility ribbon, Setup tools, Constrain tool group, click the Pin tool.


  2. Left-click on a point or edge of a part to place a pin constraint.


  3. Select the pin to toggle translation on or off along the edge.


    Note:
    You can not toggle translation if the selected edge is
    • along the draw direction, or within +/- 2 degrees
    • a closed loop
Tip: Apply a pin constraint to multiple edges by holding Ctrl while left-clicking. Once you have selected all necessary edges, left-click to place the pin constraint.

Add/Edit Blankholder

Use the Blankholder tool to create blankholder constraints.

Blankholder constraints can be defined as the upper and lower holding surfaces that control metal flow around a shape to be formed in a stamping operation. They supply a restraining force on the material during the pressing process.

  1. On the Feasibility tab, Constrain icon, click Blankholder.

  2. Select blankholder surfaces.
    Blankholder surfaces are pre-grouped and highlighted based on your cursor locaiton. If individually slected surfaces share an edge, they will be grouped together.
    • To select pre-grouped blankholder surfaces, left-click.
    • To select individual surfaces, hold the Ctrlkey and left-click.
    • To append surfaces to your selection, hold the Ctrlkey and left-click.

    Surfaces that are selected are highlighted red.

  3. Create blankholders.
    • To create a blankholder on an individual surface or group, select a surface and left-click.
    • To create blankholders for all selected surfaces, on the guide bar, click Create Blankholder.
  4. In the microdialog, define the blankholder force.
    By default, the blankholder force is Low.
    • Set the force to Low, Medium, or High.
    • Or manually enter a force value.


Add/Edit Drawbead

Create drawbead constraints with user-defined or preset values.

  1. From the Feasibility ribbon, Setup tools, Constrain tool group, click the Drawbead tool.


  2. Select the drawbead edge(s).
    Drawbead edges are pre-grouped and highlighted based on your cursor location. If individually selected edges share a point, they will be grouped together.
    • Select pre-grouped drawbead edges by left-clicking.
    • Select individual edges by holding Ctrl while left-clicking.
    • Append edges to your selection by holding Ctrl while left-clicking.
    Selected edges are highlighted red.
  3. Create drawbead(s).
    • Create a drawbead on an individual edge or group by left-clicking on a selected edge.
    • Create drawbeads for all selected edges by clicking Create Drawbead on the guide bar.
  4. In the microdialog, enter a restraining force for the drawbead, or click a preset value: L for low, M for medium, or H for high. Click the reset button to restore the drawbead to the default, which is low.
