Lock the movement of parts to simulate real-world mechanisms.
A variety of methods are available to apply alignment constraints to parts and assemblies using the Positioning Constraint tool. Use Positioning Constraint tool to maintain spatial relationships between parts , IntelliShapes, and/or assemblies.
This tool allows the user to determine the desired constraint prior to selecting any geometry and it will narrow the available types based on entity type selected. This Tool can be activated in both the normal solving mode or within the Mechanism Mode. In addition, this tool incorporates the following types:
In addition to these constraints, a Fixed in Parent Constraint can be added by right-clicking on a selected shape. This will lock all degrees of freedom for the shape which will disallow all movements. The shape is fixed in the parent space which means that the parent shape can move and the fixed shape will stay in its current position with respect to its parent.
Note: Positioning Constraints cannot be applied on IntelliShape features of Structured Parts. Positioning of features on Structured Parts are defined by the 2D Sketch Positioning. Review the 2D Sketch Positioning for details.
Note: Often during the design, constraints previously added on object may need to change and/or copies of object are created where constraints information needs to be reused and adjusted. New behaviors have been added to the constraint and dimension annotations to allow the ability to reconnect these annotations to new reference information. For example: A fastener may be co-axial aligned to a particular hole. Due to the design change, a new hole is created where a copy of the fastener is needed. After creating the copy, users can now simply drag the endpoint of the previous co-axial constraint and refer it to the newly created hole to create the new alignment for the copied fastener.
Parts and Assemblies will now display the over, under, or fully defined constraint status in the scene browser. This option can be disabled if not needed.
This functionality gives you the ability to automatically create constraints when dropping parts onto one another. The constraints will be applied speeding up your design time. The option can be turned on and off in the Tools/Options/Assembly menu.
