Tool for three-dimensional analysis of a drawing
First Claim
1. A computer system operation method for use with a system capable of displaying a plurality of views of an object taken from different vantage points, the method comprising:
- displaying simultaneously at least two views of said object wherein at least one of said at least two views is a two-dimensional view;
receiving input from a user selecting a representation of an edge of said object; and
altering the appearance of the corresponding representation of said edge in each of said at least two views in which said edge is visible to make the selected edge distinguishable from the remainder of the object.

Abstract
A method and system for assisting a user in identifying an element of an object in various displayed views in a drawing of the object. A method is employed that will allow automatic highlighting of a selected edge of an object in each view, as well as separately highlighting the edges of faces of an object adjoining the selected edge. The process facilitates the user'"'"'s comprehension of the three dimensional geometry of the object. The invention is particularly suited to computer-aided design, computer aided manufacturing, and computer aided engineering.

8. A computer system operation method for use with a system capable of displaying a plurality of views of an object taken from different vantage points, the method comprising:
-
displaying simultaneously at least two views of said object wherein at least one of said at least two views is a two-dimensional view;
receiving input from a user selecting a representation of an edge of the object;
altering the appearance of the representation of the selected edge of the object in the current view to make the selected edge visually discernable from the remainder of the object;
altering the appearance of the corresponding representation of the selected edge of the object in each other displayed view in which it is visible to make the selected edge visually discernable from the remainder of the object;
altering in the current view the appearance of the representation of the edges of faces of the object that adjoin the selected edge to make the adjoining faces visually discernable from the remainder of the object and from the selected edge; and
altering the appearance of the corresponding representation of the edges of faces of the object that adjoin the selected edge in each other displayed view in which they are visible to make the adjoining faces visually discernable from the remainder of the object and from the selected edge. - View Dependent Claims (9, 10)
identifying the edges of faces adjoining the selected edge by obtaining from a database a list of faces adjoining the selected edge;
storing said list of faces; and
obtaining from a database a list of the edges for each face in said stored list.

13. A CAD/CAM apparatus comprising:
-
an input device;
a central processing unit;
a memory device for storing data; and
a display device;
wherein the central processing unit runs an application program comprising code for obtaining data pertaining to the shape of an object, displaying simultaneously at least two views of said object with at least one of said two views being a two-dimensional view, discerning from user input an edge of said object selected by said user, and altering the representation of the object in each of said at least two views so as to distinguish the representation of the selected edge of the object from the representation of the remainder of the object in each of said at least two views.

14. A computer system operation method for use with a system capable of displaying a plurality of views of an object taken from different vantage points, the method comprising:
-
displaying simultaneously at least two views of said object with at least one of said two views being a two-dimensional view;
receiving input from a user selecting a representation of an edge of said object;
accessing a database containing information relating to the three-dimensional configuration of said object;
determining from said database the location in each view of the representation of the edge of the object corresponding to the representation of the edge selected by the user; and
altering the appearance of the corresponding representation of said edge in each view in which said representation of said edge is visible to make the selected edge distinguishable from the remainder of the object.
