You can edit the constraint after it is created to change those settings. Limits are specified values that define the allowable range of motion for components that move or rotate. Both Constrain and Joint support limits. If you are designing a mechanism with moving parts, simulating the motion is a key component of the prototyping process. Before deciding on the appropriate method, consider the following:.
Layout constraints are created when you execute Make Components. Layout constraints define the relationship between the layout and parts push derived from the layout. The Layout constraint comprises flush constraints between the three primary planes of the layout and derived parts, and a zero degree angle constraint between the Z axes of the layout and derived parts.
Layout constraints provide certain behaviors that are useful in skeletal modeling:. The default behaviors for layout constraints are initialized based on your sketch constraint relationships and options you select during Make Components. To changes behaviors for a component, right-click the component instance in the browser, select Layout Constraint in the context menu, and choose the appropriate position options. You can modify layout constraints to achieve the target behavior. However, you cannot place new layout constraints except by the Make Components workflow.
There are two ways to retain constraints for replaced components:. Convert existing assembly constraints to iMate definitions by right-clicking the component in the browser, and then selecting Infer iMates. You can also create iMates as you edit or modify a component. To simplify positioning the members of a complex assembly, create several small assemblies; apply relationships as needed, then save each one as a separate file.
This approach allows the subassembly to be positioned in upstream assemblies as a single unit. Grouping parts in subassemblies also simplifies the process of using the parts in more than one assembly. Getting started positioning components In older releases of Inventor, the first part you placed in an assembly was grounded. Its position was fixed, with the part origin coincident with the assembly origin.
It is good practice to ground at least one component that does not move to provide an anchor for other components. To ground the required component, use the context menu when you place the component and select Place Grounded at Origin. When you place a component in the assembly, use the context menu to rotate about X, Y, or Z to establish the initial orientation. Assembly joint In the following image, two assembly joint types, Rigid and Rotational, are used to locate the components and define degrees of freedom.
Assembly constrain In the following image, the constraints Mate, Flush, and Insert are used to locate components and define the range of motion. Create assembly relationships Joint command Joint can automatically determine the connection type based on origin selections.
Constrain command You select a constraint type to update the Place Constraint dialog box then select the objects to constrain. Assemble command You select the objects to constrain, and then select the type of constraint to apply. Positional limits Limits are specified values that define the allowable range of motion for components that move or rotate.
Contact sets require physical contact with other components to determine the limits. Constrain and Joint limit use assigned values to limit movement and do not require physical contact. Use limits to evaluate a design based on known maximum, minimum, and resting values.
Note: If you select the constraint option Use Offset As Resting Position, the component returns to this position after moving. The resting position for Connect is called Current and is not a fixed position.
Tip: As with contact sets, consider assembly performance when you use limits. For best performance, use limits to evaluate your design and then edit to clear the check boxes. The limit values are stored with the relationship and remain available when you reactivate the limits. Simulating the motion of moving parts If you are designing a mechanism with moving parts, simulating the motion is a key component of the prototyping process.
Before deciding on the appropriate method, consider the following: Use limits on constraints or joints to define the range of allowable movement or rotation.
Motion constraints use defined rotational or rotational-translational ratios to depict movement between components. Use motion constraints for a lightweight method to verify movement such as the proper gear ratio. Contact Sets use physical contact between components to limit movement. If interference is detected, the components do not move. This method requires more computation than a motion constraint.
Dynamic simulation uses physical properties like mass, friction, inertia matrix, and load definition to provide information on how the components act in the physical world. Use the Inventor Simulation products to study the influence and result of actual forces on your design.
This method requires the most computation but provides the most accurate results. A link to Inventor Studio enables realistic animation recording of the motion. Inventor Studio enables animation of assembly relationships and positional representations to create mechanistic motion.
Image and video output of realistic or illustrative content is the main use for Inventor Studio. Layout constraint Layout constraints are created when you execute Make Components.
