Purpose
To generate points to approximate an arc when the curve is fitted.
Syntax
|
ARC < /NUMBER Index-1 Index-2 Index-3 >< INCREMENT Angle > |
Description
This command allows the user to generate data points for an arc. When the PREFIT command is then issued the curve in this region will give a fair approximation of an arc. The arc can be specified by either 2 points (START and END) and a RADIUS or 3 points (START, END and MID).
The points may be selected using the CURSOR or specifying their reference NUMBER on the command line.
Command Qualifiers
|
None |
The user is required to select three points that lie on the intended arc. The points are selected using the CURSOR in the order START, END and the middle. |
|
/NUMBER |
This qualifier indicates that reference numbers are to be used in identifying the points. |
|
RADIUS $N |
Defines the radius of the arc. |
|
INCREMENT $N |
Defines the approx. angle in degrees between the points generated. This can be used to increase or decrease the number of points that are generated. Default 5 degrees. |
