5.  Coordinate Key-in 

General

The system supports diverse and flexible methods for coordinate key-ins.  The user can choose from  rectangular / cylindrical / spherical coordinate systems, absolute / relative coordinates, and global / current plane systems.  The currently selected modes are shown in the rightmost panes of the key-in status bar.

Whenever the user keys in values, the values entered are echoed in the key-in feedback pane next to the right of the key-in pad in the key-in status bar at the bottom of the desktop.  This allows the user to confirm what the user has just typed in. For instance, the 3 values are interpreted as Radius, Angle1 and Angle2 in the spherical coordinate system.

For a coordinate key-in, a visual cue is displayed on the screen for all three coordinate system types.  If the Relative mode is on (as opposed to Absolute mode), the screen shows a white dot indicating the current reference point a new relative key-in is to be measured from.  Normally, the coordinate key-in is done with respect to the global coordinate system.  In this CAD system, it is possible to use the current plane as the coordinate system into which to enter the coordinate values.  If Current Plane is selected as the key-in mode, the current plane assumes an orange color to denote that fact.

Description
 

Coordinate System Selector Radio Buttons:

  Rectangular Coordinate System

This icon sets the key-in coordinate mode to be such that the three values the user keys in (separated by commas) will be interpreted as X, Y, and Z values of the rectangular coordinate system.

  Cylindrical Coordinate System

  • This icon sets the key-in coordinate mode to be such that the three values the user keys in (separated by commas) will be interpreted as Radius, Angle, and Height values of the cylindrical coordinate system.

  Spherical Coordinate System

This icon sets the key-in coordinate mode to be such that the three values the user keys in (separated by commas) will be interpreted as Radius, Angle1, and Angle2 values of the spherical coordinate system.


Coordinate System Mode:

  Current Plane Coordinate

By default, when the user keys in a coordinate, the user is using the global coordinate system. Clicking this icon sets the current plane to be the default coordinate system for subsequent key-ins. Unclick this icon to return to the global coordinate system key-in mode. When the current plane is being selected, the current plane display assumes an orange color. 

 

Absolute/Relative Mode:

  Relative Mode  (on/off)

By default, a coordinate is specified in the absolute mode. Clicking this icon sets the key-in mode to be “relative”. This means all the subsequent coordinate key-ins will be measured relative to a previously established “reference point”. A point marker appears on the screen to indicate the location of the reference point. Unclick this icon to return to the absolute key-in mode.
