As you create geometry, Autodesk Inventor displays Degrees of Freedom glyphs to illustrate whether geometry is unconstrained, partially constrained, or fully constrained. As constraints are applied to the geometry and degrees of freedom eliminated, the glyphs disappear. Applying three constraints in Inventor causes it to lock up and I need to kill the process. Structural constraints restrict or limit the displacement of the model. Add constraints to mimic environmental conditions. For static simulations, remove all rigid body modes (free translational and rotational movement of the bodies). To do so, fix a face, for example, or combine partial constraints on faces, edges, or vertices. If you need assistance, activate the Simulation Guide.

More complex settings are available in the dialog boxes. Constraints are defined in the global coordinate system. The available constraint types are:. Apply fixed constraint when no movement rotation and displacement is allowed on beam or node.

To add a structural fixed, pinned, floating, or custom constraint:. Custom constraint enables you to customize all parameters of the constraint position, orientation, degrees of freedom for rotation and displacement on beam or node. To set the custom constraint values, use the Custom Constraint dialog box, or drag the grips in the graphics window. Heads Up Display input is not available. When you select Fixed option, there is no displacement allowed in this direction.

Click here to read more about types of displacement. When you select Fixed option, there is no rotation allowed in this direction. Click here to read more about types of rotation. The available constraint types are: Access Constraint Type Used to Note: You can also right-click the Constraints node in the browser and select the appropriate constraint type from the context menu. To apply a custom constraint Custom constraint enables you to customize all parameters of the constraint position, orientation, degrees of freedom for rotation and displacement on beam or node.

Parent topic: Prepare for analysis. Apply pinned constraint when no displacement and free rotation is allowed on beam or node. Apply floating pinned constraint when free rotation and free displacement in one plane is allowed on beam or node.

Apply custom constraint to specify your own degrees of freedom of displacement and rotation on beam or node. On the ribbon, click Frame Analysis tab Constraints panel Custom.

Select beam or node to position the constraint. Using the Absolute or Relative check boxes, select how you want to set the offset value. Set the Offset value. Set angles of constraint rotation about X, Y, and Z axes. Values are defined in the global coordinate system.

Specify the displacement. Use the drop-down menus to specify the degrees of freedom for X, Y, and Z axes. Specify the rotation.

Apply Constraints Automatically In a 2D sketch, geometric constraints are inferred and applied automatically as you sketch. Autodesk Inventor uses constraints in two primary ways: 2D and 3D sketch constraints control geometry within sketches Assembly constraints.
