      2. Optionally enter a Radius 1 value.
      3. Optionally enter a Radius 2 value.
      4. Optionally check/uncheck the Reverse rotation option. (unchecking selects the Belt option) - not working for 1.0 RC so far
    • Select Belt.

  6. The Parts are moved to meet at their selected entities.
  7. Optionally check the Show advanced offsets check box to fine-tune the placement of each connector relative to its related entity.
    • Two buttons labelled Offset1 and Offset2, each displaying an attachment offset, are added to the dialog.
    • Optionally press the Offset1 button to open the Placement dialog.
      This allows to adjust the attachment offset of the first connector to its related entity.
    • Optionally press the Offset2 button to open the Placement dialog.
      This allows to adjust the attachment offset of the second connector to its related entity.
    • The Parts are moved to new offset positions according to their selected entities and the attachment offsets.
  8. Press OK to finish the tool.

Notas

  • Each joint connects two parts of an assembly and connectors attached to one geometric entity of each part are used to mark the positions to match by the solver.
  • Connectors are in fact local coordinate systems and thus marked by a symbol made of three axes (X, Y, Z), and a circle (XY plane). By default, they are only visible while the related dialog is opened. They are permanently visible if their visibility is switched on manually.
  • For a joint the second connector superimposes the first connector by default and will change its position according to its type once other joints get involved.
  • Hovering the mouse pointer over a geometric entity in the 3D view, while the dialog is opened, and fewer than two entities are listed, previews where the connector will be placed once the entity is selected.

Propriedades

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

Data

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:
