Creating Parametric Tower Crane Family Open the Base Tower Crane Family Go to Front Elevation view Dimension from the top of the Reference Level (top of Tower Crane – Foundation Pad) to the Tower Crane Pick Height reference plane and add a parameter and name it Tower Crane Pick Height. This will be a Length, type parameter. Now dimension from your Center (Left/Right) reference plane to the edge of the tower cranes boom. Add another Length, type parameter and name this one Max Pick Length. Once parameters have been added, you need to make sure to flex your model as much as possible, so if there is something wrong, you notice it early on. Change the Tower Crane Pick Height to 100’ and the Max Pick Length to 140’. Make sure the crane adjusts in the model. Add two reference planes between the Center (Left/Right) reference plane and the max pick length reference plane. Dimension to these two reference planes and add a length parameter to each of these. Name them Pick Length 1 and Pick Length 2. Adding Crane Pick Radius’ - Once your two new pick length parameters have been added, move to a plan view (Ref. Level) and begin to create an extrusion. Begin to draw your crane radius using the circle tool in edit mode. Start your circle in the center of the tower crane pad. Once the circle is drawn, pick the dimension that shows up automatically, so it becomes solid.
