In Inventor 2009, an additional, optional orbit behavior was added, known as constrained orbit. Again, unless you are an AutoCAD user, this behavior may be new to you. For the existing orbit behavior, the orbit is free about the screen axes. For constrained orbit, the orbit is constrained about the Up direction of the model.
To see the difference between the two types:
- Position the model in an isometric view with the Top face of the cube on top.
- On the ribbon, click
View tab
Navigate panel
Constrained Orbit
(grouped with the Orbit command). - Position the cursor outside the reticle, adjacent to one of the horizontal markers. Click and drag the cursor across the screen. The orbit is constrained to the Up axis of the model.
- Click the Free Orbit icon
, and drag the cursor as before. Notice that the orbit axis is parallel to the screen.
If you are an AutoCAD user and new to Autodesk Inventor, you may find Constrained Orbit familiar and comfortable.
