AutoCAD Productivity
“Best of” Basics: Irregular Viewport
From: AutoCAD Productivity Articles #145
Originally published: April 2016
When you need a viewport shape other than a rectangle, the first order of business is to be able to view the objects in Model Space at the desired scale. From there, you can create a polyline to essentially ‘crop’ the objects in Model space, then turn it into a viewport.
The best drawing for testing this is in the path…
C:\Program Files\Autodesk\AutoCAD 20xx\Sample\Database Connectivity
If you have AutoCAD 2014 or prior, the drawing name is db_samp.DWG
If you have AutoCAD 2015 or later, the drawing name is Floor Plan Sample.DWG
How to Create an Irregular Shaped Viewport
Right-click on a layout tab and make a new layout with a large viewport.
Double-click in the viewport, then set the desired scale from the scale list on the Status bar. You may want to start with 1/64″ = 1′-0″ so you can see all of it.
Return to Paper space and create any closed polyline, spline or circle to be the viewport.
Note: If you are creating a Polyline, you must use the Close option if it is to be converted into a viewport. If you did not use the Close option, use Pedit and select the polyline, then use the Close option.
In this illustration, I created a polyline around the perimeter of the floorplan. (Ideally, this would be on a dedicated layer on which you typically create your viewports).
On the Layout tab, click Clip.
When prompted to select the ‘viewport to clip’, select the rectangular viewport.
When prompted to select the ‘clipping object’, select the polyline (or whatever object you created in Step 3, above).
AutoCAD will convert the polyline into a viewport and erase the original rectangular viewport!

Tip of the Day
Repeat for Efficiency
Sometimes, you may find yourself having to use the same command repeatedly. This can be a pain, unless you are aware that the previous command can always be repeated by hitting the Enter key on the keyboard or by using the right-click mouse button and selecting the name of the command you just used. Both these methods are more efficient than repeatedly finding a command on a toolbar or from a pull-down menu.
What's more annoying than having to repeat a single command (and more common) is having to repeat a sequence of maybe two or three commands. Obviously, you can't use the "Enter to repeat" trick. However, the right-click menu has another option that can help in these situations. Below the name of the last command used, is a menu option that says
. If you select this option, you will see a list of all the commands used in the current drawing session, with the most recently used at the top.Using this method, you can repeat any sequence of commands without having to return to a toolbar or pull-down menu.
Note: This function is controlled by the inputhistorymode variable.
