Defining Data to Databases
By default, points are always saved to the project point database. But
there are other objects that you must define to databases yourself,
transforming simple geometry to objects with extended entity data.
You can also assign data to objects in your drawing using the
AutoCAD Map functionality, and organize topologies in order to
analyze spatial relationships.
Objects that you can define to databases include alignments, parcels,
and breaklines. For example, to create an alignment, you first draw
the alignment geometry, such as lines and curves. These are simple
CAD objects stored in the drawing file.
Next, you must define the alignment to the alignment database,
which saves information about the points of intersection, stations,
and so on, in an external file, which you can edit in the Horizontal
Alignment Editor.
