Create/Modify Joint Attachment

(Template Builder) Build → Attachments → Joint → New/Modify            Shared Dialog Box
Creates or modifies a joint attachment. Learn about Joints.
 
For the option:
Do the following:
Joint Name
If creating a joint, enter a name for it.
If modifying a joint, enter its database name.
I/J Part
Enter the name of the i part/j part on which the joint will act.
Type
Select one of the following:
■left/right - Define either the left or the right joint, and your template-based product creates the corresponding opposite joint by default (for example, wheel bearing).
■single - Define a nonsymmetric joint (for example, steering column universal joint).
Joint Type
Select the type of joint you want to use between the two parts.
Note: The lower part of this dialog box changes based on the type of joint you select. Types of Joints explains the options available for the different types of joints.
Active
Select if the joint will only be active in the kinematic mode. Generally, a joint becomes inactive in dynamic mode if a bushing is created which models both motion and stiffness/damping of the two parts, and the joint is used only in the kinematic (motion) Analysis.
Location Dependency
Select one of the following:
If one or both of the I and J parts are flexible bodies, select one of the following:
If you select Delta Location From Coordinate, you must specify the node(s) of the flexible body at which you wish to react the attachment loads. The attachment location does not have to be coincident with the selected node(s). Note that you may select more than one node to react the load (C++ Solver only).

If you select Located At Flexible Body Node, the attachment will be reacted at the selected node. It will be located at the selected node and offset by the vector you specify, relative to the flexible body's Local Body Reference Frame. Note that you may only select one node.

See a Summary of Location Dependency Options.
If you set Location Dependency to Delta location from coordinate and one or both of the parts are flexible bodies, the following option is shown:
Selected Node, Closest Node, Closest Interface Node
Select the method to define the attachment reaction node(s). If you select Selected Node, you must specify the node(s) manually, and the attachment will be hardcoded to these node IDs. If you select Closest Node, an expression will be used to parameterize the attachment to the closest node on the flexible body. If you select Closest Interface Node, an expression will be used to parameterize the attachment to the closest interface node on the flexible body.
To set the orientation of the joint, see Types of Joints for explanation of the options available.
Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments:
■If recording comments for modeling entities in Standard Interface, your template-based product displays the Entity Comments dialog box.
■If recording comments for any other entity type, your template-based product displays the Modify Comment dialog box.
Learn about Recording Comments.
Select to enter friction properties for your joint. If you are creating a new joint, first select Apply to register the joint in the database. Displays the Create/Modify Friction Element dialog box.
You can create friction for the following types of joints:
■Translational
■Revolute
■Cylindrical
■Spherical
Displayed if joint type is Hooke or Universal. Displays the Create/Modify Friction Element dialog box. Select to create/modify I Yoke and J Yoke friction properties for your joint. If you are creating a new joint, first select Apply to register the joint in the database.
