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

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 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.

Define a plane by choosing from the following options:

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 a Position Menu option 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.
