Using the World Coordinate System for

Creating Data

When you begin a new drawing in AutoCAD Land Development

Desktop using one of the default drawing templates, you are

automatically in the World Coordinate System (WCS); the X axis is

horizontal, the Y axis is vertical, and the Z axis is perpendicular to the

XY plane.

When you are in the WCS, the AutoCAD UCS icon displayed at the

lower-left corner of the graphics screen looks like this:

If the coordinate system is set to anything other than World, the W

disappears.

If the coordinate system is set to anything other than World when

you create data in AutoCAD Land Development Desktop, that data

will NOT be processed correctly.

To change the coordinate system to World, you can type UCS on the

command line, and then type World.

WARNING!

When you are creating data with AutoCAD Land Development

Desktop, it is very important that the coordinate system be set to

world (WCS).

Working with Projects

Each AutoCAD Land Development Desktop drawing must be

associated with a project. This section describes in more detail the

function of projects and how to manage them.

■

Projects are required if you want to work with AutoCAD Land

Development Desktop commands. However, you can run AutoCAD

or AutoCAD Map command without having a project selected.

“W” indicates that the

coordinate system is

set to world
