Variables use shortcut key V.
- store a numeric value in DB;  "V{DB-index}={value}"

Implicit definition of variables by function VAL():
  Example: VAL(P20 P21)  - the distance between 2 points.

The value of variables is temporarily displayed in red in center of screen



  
V Variable - Value
V - variable value
Direct allocation of a variable or numeric expression





  
V X/Y/Z-part PT|VC
  get the X- or Y- or Z-part of a point or of a Vector.

# extract the x-coordinate of a point
V20 = X(P20)




  
V PT-PT Dist.[Direction]
  Variable = length between 2 points [into direction]

[Direction]   optional; keine Angabe: direct length between 2 points.
              Distance along a vector: define a vector

Example:
V20 = P20 P21
# distance from point P20 to point P21 into direction Z:
V21=P20 P21 DZ




  
V LN      length
V LN Length
  Variable = length of a Distance

V20 = L20




  
V PT - LN Perp.Dist
PT-V LN normal distance
  Variable = Normal distance of a point from a line

V20 = P20 L20




  
V CIR     Radius
  Variable = radius of a circle

V20 = C20




  
V Angle line/vector
  Variable = angle of a line or vector 


  Line/Vector              provide line or vector
    - get angle az in TOP-view between line and the X-axis of the active coord.system

  [tilt-angle]             Pageup / Page Down ("PERP")
    - tilt-angle ay: the angle between the line and the XY-plane of the active coord.system

  [REVers]                 Pageup / Page Down ("REV")
    - negative angle

  [complement]             Pageup / Page Down ("CX")
    - 360-degree complementry angle (360 - angle)


V20 = ANG D(L20)

 restore vector from angles:
   - vector vcx = rotate X-axis around Z-axis angle = az;
   - vector = rotate vcx around the (new) Y-axis angle = ay
       (the new Y-axis is in the XY-plane of the active coordinate-system)





  
V Angle 2 lines/vectors
  Variable = angle between 2 lines or vectors


  Line/Vector 1            provide line or vector

  [Line/Vector 2]

  [REVers]                 Pageup / Page Down ("REV")
    - negative angle

  [complement]             Pageup / Page Down ("CX")
    - 360-degree complementry angle (360 - angle)


V20 = ANG L21 L20
