2.5 Extra Steps


With all the drawing and erasing you've done in this chapter, you may have noticed that you'll occasionally "lose" a line (or other object) that you thought was there. Likewise, you may notice that an object may remain highlighted even after have canceled the command. This problem lies mostly with the video card or monitor you're using. But most programs allow you to refresh your screen after doing a great deal of work, to make sure all the screen pixels that should be lit, are lit.

Note  

By the way, I indicate commands and hotkeys using capital letters as a matter of convention. AutoCAD isn't case sensitive.

AutoCAD calls its refresh command Redraw , but that requires too much typing. When your screen needs refreshing (redrawing), type R at the command prompt and hit enter. This will redraw the screen.

In the event that what you expect to see doesn't materialize after a redraw, you have one other option. Every object within an AutoCAD drawing carries with it quite a bit of information. This information includes details about the type of object, its size , location, layer, and so forth. With AutoCAD's Regen command ( Re ), AutoCAD reads and redraws every object in the drawing. You might think this would take a lot of time in a larger drawing, and in fact, it once did. Now, however, with the advent of faster computers and better programming, regens often go unnoticed.

If the object doesn't show after a regen, it doesn't exist as part of the drawing and you'll have to redraw it.

So add these two commands to your "Hail Mary" list, but don't cut it off yet. More will follow!
