Task 2. Assemble the transmission case as the base component

     

    Component Placement is based on placement definition sets.  The first component placed is called the base component.  Other components may reference this component or the assembly features.  The transmission case part will be assembled as the base component.

  1. Click Datum Planes , Datum Points  , Datum Axes  and Coordinate Systems  in the main toolbar to toggle their display.

  2. Select  Component Assemble  icon on the right side toolbar.

  3. In the dialog box, select the TRANSMISSION_CASE.PRT and select Open.  The new component will appear in yellow on the screen as shown below.

     

    The preview button in the file open dialog box will show a graphical preview for the selected Pro/ENGINEER object using ProductView Express.

  4. In the assembly dashboard at the bottom of the screen, display the constraint list by clicking Automatic or the adjacent arrow and select Default constraint.

     

    Default constraint places the component at the assembly origin by aligning the default coordinate system of the component to the default coordinate system of the assembly.




    In the Component placement dashboard, the component STATUS will report if the component is FULLY CONSTRAINED, PARTIALLY CONSTRAINED, INVALID CONSTRAINTS or NO CONSTRAINTS.  A component is FULLY CONSTRAINED when its placement is defined in all the required degrees of freedom.  As long as the constraints are valid, the component can be Package with incomplete constraints.

  5. Select Complete Component  to complete the assembly of the case.
