Description

The Assembly CreateJointFixed tool creates a joint locking two assembly parts together, preventing any movement or rotation.

Usage

  1. Optionally select two geometric entities of two different shapes. (other numbers will result in an empty selection)
  2. There are several ways to invoke the tool:
    • Press the Create a Fixed Joint button.
    • Select the Assembly → Create a Fixed Joint option from the menu.
    • Use the keyboard shortcut: J.
  3. The Create Joint dialog opens in the Task panel listing preselected entities.
  4. Optionally change the type of the joint from the dropdown list or use a keyboard shortcut:
    • J selects the Fixed option and empties the selection list.
      1. Optionally enter an Offset value.
      2. Optionally enter a Rotation value.
      3. Optionally press to change the direction of the joint.
    • R selects the Revolute option and empties the selection list.
      1. Optionally enter an Offset value.
      2. Optionally press to change the direction of the joint.
    • C selects the Cylindrical option and empties the selection list.
      1. Optionally press to change the direction of the joint.
    • S selects the Slider option and empties the selection list.
      1. Optionally enter a Rotation value.
      2. Optionally press to change the direction of the joint.
    • B selects the Ball option and empties the selection list.
    • D selects the Distance option and empties the selection list.
      1. Optionally enter a Distance value.
      2. Optionally press to change the direction of the joint.
  5. If the selection list is empty: select two geometric entities.
  6. The shapes are moved to meet at their selected entities.
  7. Press OK to finish the tool.

Properties

See also: Property editor.

A Fixed object is derived from a ??? object and inherits all its properties. It also has the following additional properties:

Data

Joint

  • DataActivated (Bool): This indicates if the joint is active.
  • DataDistance (Float): This is the distance of the joint. It is used only by the distance joint.
  • DataJoint Type (Ennumeration): The type of the joint.
  • DataOffset (Vector): This is the offset vector of the joint.
  • DataRotation (Float): This is the rotation of the joint.

Joint Connector 1

  • DataDetach1 (Bool): This prevents placement1 from recomputing, enabling custom positioning of the placement.
  • DataElement1 (String): The selected element of the first object.
  • DataObject1 (String): The first object of the joint.
  • DataPart1 (Link): The first Part of the joint.
  • DataPlacement1 (Placement): This is the local coordinate system within object1 that will be used for the joint.
  • DataVertex1 (String): The selected Vertex of the first object.

Joint Connector 2

  • DataDetach2 (Bool): This prevents placement2 from recomputing, enabling custom positioning of the placement.
  • DataElemen21 (String): The selected element of the second object.
  • DataObject2 (String): The second object of the joint.
  • DataPart2 (Link): The second Part of the joint.
  • DataPlacement2 (Placement): This is the local coordinate system within object2 that will be used for the joint.
  • DataVertex2 (String): The selected Vertex of the second object.

Notes

  • Never select the items in the selection list and hit the Del key! This also removes the connected features from the Tree! (weekly build 0.22.0-36807)
  • This joint can be used as an actuator to control the motion of a kinematic simulation. Mouse wheel action in the Task dialog immediately rearranges the connected parts.
    - Offset translates along its local Z axis, negativ offsets are accepted.
    - Rotation revolves around its local Z axis, angles > 360° and even negativ angles are accepted.
