    Ex: 1 Solid Modelling and Assembly of Screw Jack

    Date:

    AIM: To draw the components of Screw Jack and to assemble them using

    Pro-Engineer software.

    PROCEDURE:

    1. Open pro-engineer software. Select file -New-Part and select dimension as mm.

    2. Depending on the component select the plane (Front or Top or Right or Left) and

    click sketch.

    3. Select the axis for the plane using axis line command and using line and circle

    command draw the required views of the component.

    4. Using delete command, remove unwanted lines and circles

    5. After completing the view click button. Now depending on shape of the

    component either click revolve or extrude command.

    6. In order to make a hole, click - extrude and click remove material.

    7. After extruding or revolving click button to get the complete solid component.

    8. Save the part using file - save a copy, command.

    9. All remaining components are drawn in similar manner.

    10. The drawn solid components are assembled.

    RESULT: Thus the components of Screw Jack have been drawn and assembled usingPro-Engineer software.
