Rotating a Viewport in A2010
Joining the bandwagon of reviews on cool AutoCAD 2010 features, I wanted to take you through the updated ability to rotate viewports.
Humble confession. I didn't realize this, but you have been able to rotate viewports in previous versions, as you see in this image where I'm using A2008. The trick is, you can only rotate the viewports you Convert or Clip from existing objects! The problem, however, was that the objects IN the viewports didn't rotate. [To see how to make irregular viewports, take a look at Michael's Corner September 2003 - "Irregular Shaped Viewports".]
Instructions to Rotate a Viewport in A2010
Open a drawing, then begin a New layout tab and create a viewport to view the Model space objects.
Launch the Rotate command, then select the viewport to be rotated and press Enter.
At this point, you can rotate the viewport as necessary. At the completion of the Rotate command, the objects in the viewport are rotated as well as the viewport. The next few steps take you through how to make an object in the viewport horizontal by using the Reference option of the Rotate command. [Michael's Corner, April 2003, "Scale & Rotate"]
-
Continuing with the Rotate command, when prompted to specify a Base point, you can specify a point on an object in the viewport if you want. At the prompt for Rotation angle, enter R for the Reference option.
-
You are now given the opportunity to (accurately) pick two points that define the angle you want to be orthogonal to the layout.Note: The Base point and the first point specified for the Reference angle can be the same point. The Base point is simply the pivot point, of course. You can use any two points to define the reference angle after that.
-
When prompted for the new angle, enter the desired value. In this exercise, I entered 90 so the two points I specified for the Reference angle would be vertical in the viewport.
Note: To orient the UCS to the current view, use the View option of the UCS command, View from the UCS toolbar, or View from the Coordinate panel of the View tab on the Ribbon.
Relevant variable
VPROTATEASSOC
<1> View will rotate if the viewport is rotated
<0> View will not rotate if the viewport is rotated
