<h2>CAD functions for planes and axis systems:</h2>

Planes and axis systems use the shortcut letter R.

Pre-defined planes are:
RZ             Basis level XY (Z=0)
RY             Level XZ       (Y=0)
RX             Level YZ       (X=0)

<h2>PLN Z-Axis [X-Axis]</h2>
Plane from Z-Axis (normal vector),
  optional origin, X-Axis or point on x-axis, offset along z-axis.

  [Origin]          optional;
  Z-Axis            enter DX or DY or DZ or a vektor;
                    (the Z-axis of the new plane)
  [X-Axis]          optional: the new X-axis; DX or DY or DZ
                    or a defined vector or a point on the new x-axis.
  [offset Z-axis]   optional: distance of the new origin along the
                    new z-axis



Examples:
# Plane normal to the Z-axis, with distance.
R1=PERP DZ 100
# Plane normal to the Z-axis, through point.
R2=PERP P(0 0 100) DZ
# Plane in point p1; normal to the absolute X-axis;
#   new X-axis direction of absolute Z-axis;
#   distance 10 into direction of new Z-axis.
P1=P(100 0 0)
R3=PERP P1 DX DZ 50

# Level from origin, normal vector and a point on the x-axis of the new plane
R11 = PERP P(100 100 100) D(0 0 1) P(101 100 100)


R12=PERP P(100 150 0) D(ANG(90) ANG(45))

<!--
Define a normal plane on the X-axis by entering a point or the X distance.
A plane is defined parallel to the YZ plane.
  The new X-axis corresponds to the Y-axis,
  The new Y-axis corresponds to the Z-axis.
  The new Z-axis corresponds to the X-axis.
  The plane is displayed at the X-axis (Y=0, Z=0).
   

Example:
R1=DX 100
R2=DX P(100 0 0)
R2=X(100)

<h2>PLN Y-normal</h2>
Define a normal plane on the Y-axis by entering a point or the Y distance.
A plane is defined parallel to the XZ plane.
  The new X-axis corresponds to the X-axis,

  The new Z-axis corresponds to the main Y-axis.
  The plane is displayed at the Y-axis (X=0, Z=0).

Example:
R1=DY 100
R2=DY P(0 100 0)
R5=Y(100)

<h2>PLN Z-normal</h2>
Define a normal plane on the Z-axis by entering a point or the Z distance.
A plane is defined parallel to the XY plane,
  All axis directions are the same as the main axis system RZ.
  The distance is on the Z-axis.
  The plane is displayed at the Z-axis (X=0, Y=0).

Example:
R1=DZ 100
R2=DZ P(0 0 100)
R5=Z(100)

  [Y-Axis]          optional: <a href="CAD_Base_en.htm#D">Vector</a> or point on the new y-axis
  [offset Z-axis]   optional: distance of the new origin along the
                    new z-axis


Examples:

  to the 3D Y-axis, the new Y-axis corresponds to the 3D Z-axis.
  The new Z-axis is the axis-X.
  R = X(X_distance)
