As with the Two-Point-Center Rectangle, this new for Inventor 2013 feature has actually been around for some time as an add-in created by Brian Hall. This tool does exactly the same as the Two-Point-Center Rectangle, except for the fact that it allows you to create the rectangle at an angle in the same manner as the old Three-Point Rectangle tool.
A typical workflow goes like this…
This new feature for Inventor 2013 has actually been around for a couple years as a free add-in created by QubeIt. The built-in one that is now available in Inventor is nice in that it has all of the rectangle commands in one drop-down list instead of the extra add-in one but, unfortunately, they only included two of the four tools that were in Brian’s add-in…
This new feature for Inventor 2013 takes a bit of getting used to, but when it all boils down, it’s a nice addition to the program. In the old days, when you clicked on the Create 2D Sketch button, a new sketch was automatically created on a default plane that could be configured via the Application Options. The new scheme flies out the representation of the origin planes seen to the right where you click the plane you need and you’re off to the races. The program then spins the selected plane normal to the user, the plane representations disappear, and you are ready to create a sketch.
People who nearly always create their sketches on the same plane may not like the new feature as it would be a tad slower, but for Layout Part modeling and most other workflows it’s a time saver, and its slick as snot. Really, it is 
This new Inventor 2013 feature is new in the same sense as buying a used car. It is new to you –but has been around the block. What they have done is removed some of the preference that used to be only available while you were installing Inventor, and placed them in various places within the program. This not only benefits you with the access to these settings at all times, but also makes for a much smoother install. I can say from my recent (two days ago) experience installing Autodesk Product Design Suite 2013, that it installed flawlessly -without a single nag screen –a vast improvement over previous versions where Inventor alone was a nightmare to install (Product Design Suite 2013 has a huge amount of included programs, and all of them installed effortlessly and attended from a flash drive).
Sorry for the delay getting this post out. Windows 7 went absolutely batty on me on Monday, and it took a full two days (30 hours total) to hose the installation and start with a clean slate. Luckily this Inventor 2013 New Feature is incredibly brief. In Inventor 2013, two of the default settings in the Application Options have changed –both of them on the Sketch Tab.
This New Feature for Inventor 2013 is obviously geared specifically towards the Inventor noob. What it does is this; noob (or overzealous old-timer) clicks on Extrude or Revolve with no Sketch (not the more common lack of closed loop –no sketch at all!).This is not actually what pops up. You get the expanded version shown below…
