34 | Chapter 3 Working with COGO Points
Introduction
Points that AutoCAD Land Desktop creates are called COGO points. COGO
stands for Coordinate Geometry. COGO points are stored in an external
database and are organized by their point numbers. COGO points have
extended entity data associated with the points that includes point number,
point name, description, elevation, northing, and easting.
COGO point data is stored in an external database file called points.mdb,
which is referenced by all drawings in a project. Because project points are
stored externally, you can reference them without drafting them in a
drawing. Point data can be accessed by multiple people on a network.
To add points to the point database, you can do the following:
■ Create points using the Create Points commands on the Points menu.
■ Import ASCII files.
■ Import data from a Microsoft
®
Access database file.
■ Download from a data collector.
The following diagram illustrates the several ways to add points to a project.
