    CAD Lines

    Lines use the identification letter L ("Line").

      LN PT  PT
    Line between 2 points

      Startpt           Startpoint of the line
      Endpt             Endpoinoint of the line
      [unlimited]       limited / unlimited

    Example:
    L1 = P1 P(100 100)

      LN parallel
    Line parallel to a line / vector, through a point.
     For the point can be defined a X-Offset, Y-Offset and Z-Offset.

      Direction         direction of the line as vector
      [BasePoint]       a point on the line
      [Length]          length, optional.
      [X-offset]        X-offset from BasePoint
      [Y-offset]
      [Z-offset]
      [unlimited]       limited / unlimited

    Example:
    # parallel to X-axis, with Y-offset:
    L2=DX Y(10)

      LN PT Direct. [Length,Rot.Angle,TiltAngle]

    Line through point, parallel to vector / line;
      rotated in the constructionplane or tilted.

      Point             a point on the line
      Direction         direction of the line as vector
      [Length]          length, optional.
      [Angle-Rot.]      Rotation angle in the constructionplane
      [Angle-Tilt]      Tilt angle normal to the constructionplane
      [unlimited]       limited / unlimited

    Examples:
    # Line from point with a fixed angle
    L3=P1 ANG(45)

    # Parallel to line L1 through P1
    L4= P1 D(L1)

    # Line from point with angle relative to the other line.
    L4=P1 D(L1) ANG(90)

      LN LN Dist.          (parall)
    Line parallel to line spacing.

      parall to Line   baseline (direction)
      Dist.            Normal distance of line from baseline
      [Position]       no value: left; Versionnumber
                       1, 2 lateral left / right; 3, 4 top / bottom

    Examples:
    # parallel to L10, distance 10, above:
    L8=L10 VAL(10) MOD(3)

      LN LN LN [Rotate Tilt] (mid)
    Line as a midline of two lines (a bisection line through the intersectionpoint).
      Can be rotated and tilted.

      Line 1
      Line 2
      [Angle-Rot.]      Rotation angle in the constructionplane
      [Angle-Tilt]      Tilt angle normal to the constructionplane

    Examples:
    L26=L23 L24                  # angle bisector, from intersectionpoint
    L27=L23 L24 ANG(90)          # angle bisector, additionally rotated

     LN tangent to 2 objs",            "TNG"
    Create a tangential line between 2 curve-objects.
    Inputelements can be: points, circles, curves.

    - get the tangential line from:
      - select curve and point on that curve for a tangent or
      - select vector or line (define the direction) and a curve or
      - select two curves (eg 2 circles)

      object 1
      object 2
      [solutionNr]      solution-nr
      [REVers]          fwd / bwd (key Pageup / Page Down, see REV)
      [unlimited]       limited / unlimited

    If one object is a line or a vector:
     create tangent with constant direction (parallel to line/vector).

    Tangent to curve through point on this curve; one solution only; select point first
    Tangent from point outside curve to curve;    n solutions;       select curve first

    solutionNr / object -:

    Examples:
    # Line tangent to a circle, parallel to the line.
    L1=C1 D(L1) MOD(1)

    # Line tangent to 2 circles
    L5=C1 C2 MOD(1)
