3. Select the edge that will be the hinge or the edge about which the polygons will
extrude and rotate. To select the hinge edge, click the Pick Hinge button in the dialog
box next to the Current Hinge parameter. Then, in the viewport, go to the selected
polygon and choose which edge you want to use.
4. Once you select the hinge, the polygon will hinge out, rotating about that selected
edge however many degrees are cited in the Angle parameter. You can use the spinner
to select or you can enter the desired angle value for the hinge. The model will interactively
hinge the polygon as you set the Angle value. Figure 4.38 shows a small hinge.
Notice the hinge is flat, as it only has a Segments value of 1.
5. In the Settings window, change the Angle value to 90, and the Segments value to 5.
Press OK to complete the function. Figure 4.39 shows the results.
The Hinge from Edge tool is an interesting way to extrude, and it can be handy in many
instances, such as when you??™re creating an awning or a curved overhang. Remember, the
smoother you need the hinge to be, the more segments you will need to add.
