Drawings can contain
various kinds of errors that make accurate mapping difficult. For
example, digitizing from a paper map can produce lines that were
actually creases in the paper.
Drawings edited by multiple
people can contain duplicate lines or objects. Finding duplicate
objects in the same location can be nearly impossible without the
If lines in your drawing
do not connect precisely at endpoints, data that appears to be precise
can actually be inaccurate. Locating these issues visually can take
AutoCAD Map 3D has an option
called Drawing Cleanup to help you
correct common geometry errors. In this lesson, you clean up a street
map by deleting duplicate objects and extending undershoots. It
is best to perform each operation separately, so you can see the
result of each operation before performing the next one.
Optionally, you can use
a cleanup profile to automate the drawing cleanup process with scripts
or to share settings with other users.
