PROJECT allows you to map selected entities onto a 
specified plane, along a specified vector.

Indicate the projection by choosing from the following
options:

NORMAL - to project the selected entities along a vector
normal (perpendicular) to the projection plane.

SKEWED - to project the selected entities along a vector 
you define.

Indicate the method of transformation by choosing from the
following options:

MOVE - to apply the transformation directly to the 
selected entities. All non-geometric data relating 
to the entities is preserved.

COPY - to apply the transformation to copies of the 
selected entities. Copies are created on the active level
and retain the attributes of the original geometry. All 
non-geometric data relating to the entities is preserved.
You can create as many copies as you want in one 
operation. The transformation for a given copy is 
applied to the results of the previous copy.

JOIN - to apply the transformation to copies of the 
selected entities and create lines from join positions on
the original entities to corresponding positions on the
copies. The new joining entities are lines that assume 
all the current default line attributes. Coincident
positions generate only one joining entity.

Joined copies are created on the active level; all 
non-geometric data relating to the entities is preserved;
you can create as many copies as you want in one 
operation; the transformation for a given copy is applied 
to the results of the previous copy.

Select the desired entities, using a Selection Menu 
option.

Define the projection plane by choosing from the following
menu:

3PTS - to define a plane with two or three points in 
space. To define the plane normal to the construction 
plane and containing two positions, indicate two positions
and press <Enter> for the third position. To define the 
plane containing three positions, indicate the three 
positions. 

PT/LINE - to define a plane with a point in space and the
endpoints of a selected line by indicating the position
using the Position Menu and selecting the line.

2 LINES - to define a plane containing two intersecting
lines (or potentially intersecting lines) by selecting the
desired lines.

VW/DPTH - to define a plane corresponding to a constant
depth in a specified view. Enter the view number.

Indicate the depth by entering the depth directly (VALUE) 
or by indicating a position at the desired depth, using a
Position Menu option.

ENTITY - to define the plane containing a 2-D entity or 
the plane that contains a line and is normal to the 
construction plane. Select a line, arc, conic, or 2-D
spline.

If you chose PROJECT/SKEWED, define the desired direction
by choosing from the following options:

2 PTS - to define the scaling direction by creating a
vector. The vector is defined by choosing two points. The
entity is scaled from a base plane that runs normal
(horizontal) to the defined vector. 

KEY-IN - to key-in the scaling direction vector. The 
entity is scaled from a base plane that runs normal 
(horizontal) to the defined vector and through the 
base position. The COORD: function in the Status Window 
indicates whether the coordinates are world or view.

VIEW - to define the scaling direction as being
perpendicular to a view's display plane. The entity will 
be scaled vertically from a plane that runs through the 
base position and parallel to the view's display plane. 

2D ENT - to define the scaling direction as being
perpendicular to a plane as defined by an arc, conic, or 
2-D spline. The entity is scaled from a plane that runs
through the base position and parallel to the plane 
defined by the arc, conic, or 2-D spline.
