ProgeSOFT IntelliCAD – Working with coordinates

For accuracy in a drawing, you can locate specific points by entering coordinates as you draw or modify entities.
When you create two-dimensional entities, you enter two-dimensional coordinates; for three-dimensional entities, you specify threedimensional coordinates.

You can also specify coordinates in relation to other known locations or entities in a drawing.
In particular, when you work in three-dimensional drawings, it is often easier to specify coordinates in relation to a two-dimensional working plane, called a user coordinate system (UCS).

This chapter explains how to work with coordinates, including how to:

• Use two-dimensional and three-dimensional coordinate systems.
• Specify absolute and relative coordinates.
• Specify polar, spherical, and cylindrical coordinates.
• Define and manipulate user coordinate systems.
