5 PTS allows you to create a conic based on positions 
for five points on the conic.

Indicate the start point of the conic, using a Position 
Menu option.

Indicate the second point of the conic, using a Position
Menu option. 

Indicate the third point of the conic, using a Position 
Menu option.

Indicate a fourth point of the conic, using a Position 
Menu option.

Indicate the end point of the conic, using a Position Menu
option.

If a conic cannot be created, an error message is 
displayed. You are prompted to press <Enter> and to 
redefine the conic,beginning with the position of the 
start point.

In 2-D construction mode, the indicated points are 
projected to the current construction plane. The conic 
is created in the current construction view, at the depth
that is active when the endpoint is defined.

In 3-D construction mode, the conic is created in the 
plane that is defined by the first three indicated points.
The fourth and fifth points are projected to this plane.
