CAD functions for planes and axis systems:
<A HREF="CAD_Base_en.htm">See operating CAD</A>

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)


<A NAME="F0"></A>Specifying Planes:

PLN X-normal (Plane, R)

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)


<A NAME="F1"></A>
PLN Y-normal
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 Y-axis corresponds to the Z-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)


<A NAME="F2"></A>
PLN Z-normal
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)


<A NAME="F3"></A>
PLN PT Z-Axis [PT_X-Axis]
Plane of origin Z axis vector [X-axis point]
   Z-axis vector: the normal vector of the plane
   X-axis point: a point on the X-axis of the new plane;

Examples:
R10 = P(100 100 100) DZ
R11 = P(100 100 100) D(0 0 1) P (101 100 100)
R12 = P154 D(ANG(90) ANG(45))
R13 = P(100 100 100) L(P(0 0 0) P(0 0 100))

<A NAME="F4"></A>
PLN PT Z-Axis X-Axis PERP
Plane of origin, normal vector and X-axis vector:
   Z-axis vector: the normal vector of the plane
   X-axis vector: defines the direction of the X-axis of the new plane;

Example:
R21 = PERP P(50 50) DX DY

<A NAME="F5"></A>
PLN PT X-Axis VEC_in_Plane
Plane of origin X-Axis Vector Vector_in_the_plane
   X-Axis Vector: The direction of the X-axis of the new plane;
   Vector_in_the_plane: Another vector in the new plane.

Example:
R12 = P(100 100 100) D(1 0 0) D(0 1 0)
R20 = P(100 100 25) DX DY

<A NAME="F6"></A>
PLN PT PT PT
Plane/reference system by the three 3D points po px pt;
   Po = the origin point,
   Px = a point on the x-axis of the new plane,
   Pt = a point in the plane (which must not be in line with po-px)

Example:
R4 = P(100 100 100) P(101 100 100) P(100 101 100)

<A NAME="F7"></A>
PLN PT  Plane
Moving of a plane/reference system (the axes will remain),
by entering the plane and the new origin.

Example:
R21 = R20 P(100 100 50)
