Controlling Constraint Limits with Autodesk Inventor - Page 2

By John Koop, TEDCF Publishing

The next section is the Limits section. The first option is the Use Angle As Resting Position option. If you click this box, whatever angle you have specified will be the resting position. This means that when you click and drag the component to move it, it will snap back to the resting position. The last options are the Maximum and Minimum options. Here you can specify a range that your constraint can move in. When you specify a range, the range limits will automatically be inserted if you drive the constraint.

I am going to set some constraint limits for this hinge.

I named my constraint, Hinge Movement. I then set the Resting Position to 180 degrees, and set the Max to 270 and Min to 0. This will give an actual representation of how the hinge works. Now I can click and drag to simulate the movement of the hinge, or I can drive the Hinge Movement constraint within the pre-defined constraint limits. Using constraint limits can make driving your constraints much simpler, and naming them makes it easier to keep track of what each constraint does, just by looking at the names.
