Abstract

When a user is drawing with a computer-aided design application that allows two dimensional (X, Y) or three dimensional (X, Y, Z) drawings, it is very difficult for the user to know the currently selected dimensions and the position of the cursor in those dimensions.

Cursor for Computer-Aided Design Applications

      When a user is drawing with a computer-aided design application
that allows two dimensional (X, Y) or three dimensional (X, Y, Z)
drawings, it is very difficult for the user to know the currently
selected dimensions and the position of the cursor in those
dimensions.

      Since the computer screen is flat, the user draws in only one
or two dimensions at a time and quickly moves between dimensions.
This occurs, for example, when the user draws an angled line through
the X, Y, and Z dimensions.

      The cursor for Computer-Aided Design is shown in Fig. 1.  The
cursor shows the user the currently selected dimensions and the
position of the cursor in those dimensions by including the
dimensions and values in the cursor itself.  The dimension values
change as the user moves the cursor.  The cursor shows the user the
X, Y, and Z (if applicable) dimension axes.  When the user is drawing
in a particular dimension or dimensions, then those dimension labels
(X, Y, or Z) appear along their axes in the cursor.  So, if the user
is operating a three-dimensional computer-aided design drawing
application, and the user is drawing in only the Z dimension, then
the "Z" axis label appears on the cursor.  The dimension values
appear in the cursor in the familiar X, Y, Z order.  As the user
moves the cursor, the dimension values change.  Fig. 2 shows a cursor
being moved in only the Z dimension.
