The order in which you select the points and the spread of the points
affects the results. For complex curved figures, more vertices result in
a more accurate alignment.

Where you are now
You created a drive alias for drawings stored on a shared drive. You
georeferenced drawing objects, using the Rubber Sheet command to align
them with known locations.

Lesson 2: Clean Up Your Drawings
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 right tools.
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 hours.
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.
