Datasheet

You can also change the overwritten dimensions automatically, which may cause even
more problems if you don’t notice what got updated. The problem is that the value is
probably overridden because the geometry is wrong.
SYSVDLG The System Variables editor is a wonderful tool.
It gives you a concise list of each system variable, tells you
where its value is stored, and describes what it does. The best
thing is that you can save the settings to an SVF file and
restore them if you ever have to. If you do any training using
computers that aren’t your own, take this file with you; it will
reduce the number of surprises you may encounter.
OVERKILL This command gets rid of overlapping lines, line
segments that connect in what appears to be a single object,
and duplicate objects on top of other objects. It can clean up
a mess of a drawing in a hurry; see Figure 1.22.
OVERKILL doesn’t always work correctly. I’ve found that it works best if you use it for one kind
of cleanup at a time (pline, overlaps, end-to-end) even though the dialog box allows you to
check every type at once. Run it for each type separately to get the results you want.
