  1. Click File > New.

  2. Select the Mechanical Imperial template.

    SHARED Tip Selecting the Mechanical Imperial template creates a document with a C-wide sheet and a 1:1 scale.

  3. On the Main toolbar, click Symbol Explorer Symbol Explorer.

  4. Browse to the folder with the field pump symbols.

  5. From the Symbol Explorer, drag the foundation symbol in the lower left area of the document.

  6. From the Symbol Explorer, drag the pendulum, donkey head, beam rod, and pump thread symbols so that these do not overlap each other or the foundation.

To connect the parts

  1. On the Tools menu, select Maintain Relationships. Your action confirms that the relationships are maintained when you move parts of the drawing.

  2. On the Relationship toolbar, click Lock Lock.

  3. To lock the foundation, select one of the end points of the line on the lower right side. This action keeps the foundation stationary when you attach the other components or animate the movement.

To connect the pendulum to the motor on the foundation

  1. On the Relationship toolbar, click Concentric. Concentric.

  2. Select the circle on the left end of the pendulum arm as the first element.

  3. Select the small circle on the motor as the next element. The pendulum moves so that the circles align and are concentric.

SHARED Tip The pendulum appears on top of the motor and the foundation. If the pendulum does not do this, select the pendulum using Select on the Draw toolbar. You can then click Bring To Front on the Change toolbar. This action ensures that the pendulum is on top of the motor and foundation.

To connect the donkey head to the top of the foundation

  1. On the Relationship toolbar, click Concentric.

  2. Select the circle at the center of the donkey head for the first element.

  3. Select the circle at the top of the A-frame of the foundation symbol for the second element. The donkey head moves so it appears balanced on top of the A-frame and the circles align.

To connect the beam rod to the pendulum

  1. On the Relationship toolbar, click Concentric.

  2. Select the lower circle on the beam rod for the first element.

  3. Select the right-most circle on the pendulum arm for the second element. This circle is almost centered on the pendulum. The rod moves and connects with the pendulum.

To connect the beam rod to the donkey head

  1. On the Relationship toolbar, click Concentric.

  2. Select the circle on top of the beam rod for the first element.

  3. Select the circle on the left side of the donkey head for the second element.

    The pendulum, donkey head, and beam rod now move so that the connections are complete.

SHARED Tip The beam rod appears on top of the pendulum. Otherwise, click Select Tool on the Draw toolbar. You can then click Bring To Front on the Change toolbar. This action ensures that the beam rod appears on top of the other parts.

To connect the pump thread to the donkey head

  1. On the Relationship toolbar, click Connect Connect.

  2. Click the top of the line on the pump thread.

  3. For the second element, select the endpoint of the small line embedded along the right edge of the donkey head. The thread moves and attaches to the head.

SHARED Tip You can zoom on the edge of the head to find this line, because it is very small. On the Main toolbar, click Zoom Area Zoom Area.

To place a dimension on the pendulum for controlling the rotation angle

  1. Click Tools > SmartSketch Settings.

  2. On the Relationships tab of the SmartSketch dialog box, ensure that the Midpoint check box is set.

  3. On the Dimension toolbar, click Angle Between to place the dimension. The dimension is driving, so it appears in black Angle Between.

    SHARED Tip To select the circle on the pendulum where it connects to the motor, zoom in close enough to see the entire pendulum in full view. On the Main toolbar, click Zoom Area.

    You must select the right circle to ensure that a driving dimension is placed. If you use the wrong circle, the dimension will be a driven dimension, shown as green. If this should occur, delete the dimension and try again.

  4. Pass the pointer over the circle where the pendulum connects to the motor. You see three ellipses appear next to the pointer.

  5. Click to see a box. This is PickQuick. The box has two numbers. This PickQuick box indicates how many elements you can select at this location in the window. In this case, you can select only two elements.

  6. Click the number 2 square.

  • You can see three squares in the PickQuick box, depending on the zoom distance when you see the ellipses. If you see more than two squares, dismiss the PickQuick box by selecting the X in the upper right, and then zoom in closer and try again. On the Main toolbar, click Zoom Area. After you can see only two numbered squares in the PickQuick box, select the number two square. This action selects the circle associated with box number two as the first point of the dimension.

  • If PickQuick does not appear, you can also click Bring To Front and click the motor symbol to bring it to the front to try the previous steps. You need to click Send To Back after you complete the steps to bring the pendulum back to the front.

  • Pass the pointer over the line on the right end of the pendulum and move slowly toward the mid-point of the line. When you see the midpoint indicator, click for the second point of the dimension. Place the dimension to the right of the pendulum. Location is not important. This dimension drives the animation of the pump.

To drive the model

  • After you place the dimension, you can select the dimension with the Select Tool and change the value in the ribbon. When the dimension changes, the angle of the pendulum changes and all of the other parts change accordingly.
