50 Chapter 2: Creating Basic Drawings
Example of Cartesian Coordinate Input
The following lines could have been drawn using Cartesian or Polar coordinates. Assuming the start
point at the red arrow, the command line input for relative Cartesian or Polar coordinates would be as
follows:
Point 2: @4,0 or @4<0
Point 3: @0,2 or @2<90
Point 4: @-1,0 or @1<180
About Dynamic Input
The Dynamic Input interface is a way of entering data dynamically. Rather than entering data on the
command line, which is generally positioned at the bottom of the screen, you can use the Dynamic
Input interface for heads-up design, entering command information on screen at the cursor location.
Using the Dynamic Input Interface
The Dynamic Input interface is context sensitive based on the current operation. For example, the
input and options are different when you are drawing a line than when you are drawing a circle; they
also differ based on whether you are creating or editing geometry.
Dynamic Input Interface: Dimensional Input Mode
There are two Dynamic Input interface modes: Dimensional Input and Pointer Input. The following
image represents the Dynamic Input interface in Dimensional Input mode. This mode is available
when the Dynamic Input option is selected in the status bar and is commonly used for the typical
drawing commands such as Line, Circle, and Arc.
Note: Numbers in the following image correspond to the numbers in the list below.
