Abstract
Abstract A plan view (PLV) and a front view (FRV) of a three-dimensional object (OB) are drawn, and a cross cursor (CS) is displayed. The cross cursor (CS) is used to define a predetermined rectangular parallelepiped region (REp) on the plan view (PLV) and a predetermined rectangular parallelepiped region (REf) on the front view (FRV). The vertex coordinates of the rectangular parallelepiped are calculated using the defined regions (REp, REf) to determine a rectangular parallelepiped region.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
99 words
A rectangular parallelepiped area designating method for designating a predetermined rectangular parallelepiped area in a three-dimensional displayed object displayed on a display screen, characterized by: displaying at least two views from among a plan view, front view and side view of the three-dimensional displayed object on the display screen along with a cursor; designating positions of apices of the rectangular parallelepiped area in each view using said cursor; computing coordinates of each apex of a rectangular parallelepiped in each view using the coordinates of apex positions designated; and specifying the rectangular parallelepiped area by the coordinates of each apex.
Claim 2
Dependent Claim
99 words
A rectangular parallelepiped area designating method for designating a predetermined rectangular parallelepiped area in a three-dimensional displayed object displayed on a display screen, characterized by: displaying at least two views from among a plan view, front view and side view of the three-dimensional displayed object on the display screen along with a cursor; designating positions of apices of the rectangular parallelepiped area in each view using said cursor; computing coordinates of each apex of a rectangular parallelepiped in each view using the coordinates of apex positions designated; and specifying the rectangular parallelepiped area by the coordinates of each apex.
Claim 3
Dependent Claim
39 words
A rectangular parallelepiped area designating method according to claim 1, characterized in that positions of two points on a diagonal of a rectangular shape obtained by projecting the rectangular parallelepiped onto each view are designated as said apex positions.
Claim 4
Dependent Claim
30 words
A rectangular parallelepiped area designating method according to claim 2, characterized in that when said two points on the diagonal are designated, said rectangular shape is displayed in each view.
Claim 5
Dependent Claim
28 words
A rectangular parallelepiped area designating method according to claim 1, characterized in that said cursor is a cross-hair cursor having cross hairs displayed in full on the screen.
