6. The Parts are moved to meet at their selected entities.
7. Press OK to finish the tool.

• A fixed joint can be used as an actuator to control the motion of a kinematic simulation. Mouse wheel action in the Task panel immediately rearranges the connected parts.
  • Offset translates along its local Z axis, negative offsets are accepted.
  • Rotation revolves around its local Z axis, angles > 360° and even negative angles are accepted.

A Fixed object is derived from an App FeaturePython object and inherits all its properties. It also has the following additional properties:

Joint

• DadosActivated (Bool): This indicates if the joint is active.
• DadosDistance (Float): This stores the Distance of the Distance joint. It is also used by the RackPinion and Screw joints to store the Pitch radius, and by the Gear, and Belt joints to store Radius1.
• DadosDistance2 (Float): This is the second distance of the joint. It is used only by the Gear and Belt joints to store Radius2.
• DadosJoint Type (Ennumeration): The type of the joint. (Fixed, Revolute, Cylindrical, Slider, Ball, Distance, Parallel, Perpendicular, Angle, RackPinion, Screw, Gears, Belt)

Removed properties (v.1.0.0-RC-38728) These were the properties that could be used to animate:

• DadosOffset (Vector): This is the offset vector of the joint.
• DadosRotation (Float): This is the rotation of the joint.

Joint Connector 1

• DadosDetach1 (Bool): This prevents placement1 from recomputing, enabling custom positioning of the placement.
• DadosOffset1 (Placement): This is the attachment offset of the first connector of the joint. (added with v.1.0.0-RC-38728)
• DadosPlacement1 (Placement): This is the local coordinate system within reference1's object that will be used for the joint.
• DadosReference1 (XlinkSubHidden): The first reference of the joint.

Removed properties:

• DadosElement1 (String): The selected element of the first object.
• DadosObject1 (String): The first object of the joint.
• DadosPart1 (Link): The first Part of the joint.
• DadosVertex1 (String): The selected Vertex of the first object.

Joint Connector 2

• DadosDetach2 (Bool): This prevents placement2 from recomputing, enabling custom positioning of the placement.
• DadosOffset2 (Placement): This is the attachment offset of the second connector of the joint. (added with v.1.0.0-RC-38728)
• DadosPlacement2 (Placement): This is the local coordinate system within reference2's object that will be used for the joint.
• DadosReference2 (XlinkSubHidden): The second reference of the joint.

Removed properties:

• DadosElement2 (String): The selected element of the second object.
• DadosObject2 (String): The second object of the joint.
• DadosPart2 (Link): The second Part of the joint.
• DadosVertex2 (String): The selected Vertex of the second object.

Limits

• DadosAngle Max (Float): This is the maximum limit for the angle between both coordinate systems (between their X axes).
• DadosAngle Min (Float): This is the minimum limit for the angle between both coordinate systems (between their X axes).
• DadosEnable Angle Max (Bool): Enable the maximum angle limit of the joint.
• DadosEnable Angle Min (Bool): Enable the minimum angle limit of the joint.
• DadosEnable Length Max (Bool): Enable the maximum length limit of the joint.
• DadosEnable Length Min (Bool): Enable the minimum length limit of the joint.
• DadosLength Max (Float): This is the maximum limit for the distance between both coordinate systems (along their Z axis).
• DadosLength Min (Float): This is the minimum limit for the distance between both coordinate systems (along their Z axis).

Removed property:

• DadosEnable Limits (Bool): Is this joint using limits?
