WIPEOUT – This by many forgotten command can save you a lot of time and effort.
A Wipeout is an image type object. Most commonly it is used to “mask” part of a drawing for clarity.
I’ve rediscovered it recently and found it useful when creating louvers. With hundreds of them I didn’t need to cut and trim additional few hundreds lines of windows behind them. And reposition of them was so easy. I also used it for window tags and handles in elevation view.
The Wipeout command can be used for 3 different operations.
It can be used to draw a Wipeout object, as you might expect (only without arcs), but it can also be used to convert an existing closed Polyline (only without arcs) into a Wipeout. Additionaly it can be used to control the visibility of Wipeout frames.
You can also change Wipeout frames directly from WIPEOUTFRAME system variable. The result of available value is below.
|0||Frames are not displayed or plotted. Frames are temporarily displayed for object selection and selection preview.|
|1||Frames are displayed and plotted|
|2||Frames are displayed, but not plotted|
Value no.2 exist since AutoCAD 2013.
Personally I use value.1 to not duplicate the lines and when I need to make a particular frame unvisitable I change it line type to thin doted line with a big scale (like 1000). Only corners then are visible as dots. I use this method to create hollow objects like window frame.
