Create Joint Hubs
Use the Joint Box tool to define junctions in your skeleton model.

- 
                From the Skeleton ribbon, click the Joint Box
                    tool.

- 
                Select the node or elements around which to create a bounding box.
                Any elements found within the box are used for joint creation.

                    options.- Create joint box
- Use the box as a mechanism to select elements to generate the joint location and legs.
- Remove joint legs
- Create a joint without the corresponding legs.
- Mesh member joint
- Automatically create 1D mesh on the joint legs and apply the beam sections.
- Dimensions
- 
                                Controls the length, width, and weight of the bounding box. 
- Use orientation and dimensions
- For repeated operations, the previous box attribute information can be used so that the box can be created the same repeatedly.
 
- 
                Edit the box size in the following ways:
                - Click  in the microdialog to

                If the member joint is being meshed, set the parameters in the microdialog drop-down.
                This automatically creates 1D mesh on the joint legs and applies the beamsections.

- Optional: Click the Exclude selector on the guide bar then pick entities to exclude from the joint if required.
- 
                On the guide bar, click one of the following:
                 - Apply and stay in the tool - Apply and stay in the tool
 - Apply and close the tool - Apply and close the tool
 - Exit the tool without applying - Exit the tool without applying
 
Assign Beam Sections to Member Joints
Use the Assign tool if a member joint is created without a beam section or the beam section needs to be changed.
- 
                From the Skeleton ribbon, Joint Box tool group, click the
                        Assign tool.

- Select the member joint(s).
- Select the beam section to assign.
