Inventor 2009 Part II

Let's start at the beginning. Sketches. Some very nice features were added to the sketch environment, and I will get to part of them here.

Degrees of Freedom; you can highlight a sketch, then right-click and select Degrees of Freedom.

The red (in this color scheme) arrows indicate that you can move the item (in this case, lines and vertices) in the direction(s) indicated. And, of course you will have curved arrows for angles, etc.

Thumbs Up; Just a nice little touch to make it easier to understand how to completely constrain a sketch.
