Assembly joints position components and fully define the degrees of freedom.

Access

Ribbon: Assemble tab Relationships panel Joint

The Joint command creates relationships which control position and movement. You can select endpoints, midpoints and center points to create relationships.

Joint tab

Type

Automatic

The origin selections are used to determine one of the following joint types:

• Rotational is selected if the two selected origins are circular.
• Cylindrical is selected if the two selected origins are points on a cylinder.
• Ball is selected if the two selected origins are points on a sphere.
• Rigid is selected for all other origin selections.

If you know the connection requirement, you can choose one of the following defined joint types:

Rigid

Positions a component and removes all degrees of freedom. Use this joint type for components that do not move. Welded and bolted joints are examples of a rigid joint.

Rotational

Positions a component and specifies one rotational degree of freedom. Supports user specified limits. Hinges and rotating levers are examples of a rotational joint.

Slider

Positions a component and specifies one translational degree of freedom. Supports user specified limits. A slide block moving in a track is an example of a slider connection.

Cylindrical

Positions a component and specifies one translational and one rotational degree of freedom. Supports user specified limits. A shaft in a bushing is an example of a cylindrical joint.

Planar

Positions a component and specifies two translational and one rotational degree of freedom perpendicular to the linear. Use this joint to place a component on a planar face. The component can rotate or slide on the plane.

Ball

Positions a component and specifies three rotational degrees of freedom. A ball and socket joint is an example of a ball joint.

Gap

Gap value

Specifies distance by which connected components are offset from one another.

Name

Creates a unique name for the connection in the browser. You can enter a name or leave blank and a default name is automatically created.

Suppress

Check to suppress joints.

Connect

First origin

Selects endpoints, midpoints and center points on the first component. The first selection origin is previewed in the same color as the select button color bar in the graphics window. The first selected component moves to the second selected component.

Second origin

Selects endpoints, midpoints and center points on the second component. The second selection origin is previewed in the same color as the select button color bar in the graphics window.

Flip component

Reverses the direction of the component.

Pick part first

Limits the selectable geometry to a single component. Use when components are close to or partially obscure one another. Clear the check box to restore selection mode.

Align

First alignment

Selects direction vector faces or edges on the first component.

Second alignment

Selects direction vector faces or edges on the second component.

Invert alignment

Reverses the direction of the alignment.

Animate

Select to play the joint behavior on the moving component in the graphics window.

on change

Select to preview the joint behavior when the joint type is changed. Clear the check box to disable automatic preview.

Angular

Start

Sets the minimum extent of connection rotational movement. Check the box to activate. Clear the check box to deactivate. The assigned value is retained when the check box is cleared.

Current

Sets the temporary rest position. The position is subject to be overridden.

End

Sets the maximum extent of joint rotational movement. Check the box to activate. Clear the check box to deactivate. The assigned value is retained when the check box is cleared.

Linear

Start

Sets the minimum extent of joint translational movement. Check the box to activate. Clear the check box to deactivate. The assigned value is retained when the check box is cleared.

Current

Sets the temporary rest position. The position is subject to be overridden.

End

Sets the maximum extent of joint translational movement. Check the box to activate. Clear the check box to deactivate. The assigned value is retained when the check box is cleared.
