<h1>Lines</h1>

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



<p><a name="Copy"></a></p>
  <h2>Line from Copyfunction</h2>
Objectselections create this formats:

# Line of Polygonsegment
# or Line of Line in  CCV:
L({obj} MOD({SegmentNumber}))

# Line of Polygonsegment in CCV:
L({obj} MOD({CCV-SegmentNumber}) MOD({SegmentNumber}))


<u>Example:</u>
# Line of 1.Segment of CCV S26 (a Line):
L(S26 MOD(1))

  <h2>LN PT  PT</h2>
 Line between 2 points 
 L1 = P1 P (100, 100)
 
 

 <a name="F1"></a>
  <h2>LN parallel</h2>
 Line parallel to a vector, through a point.
 It can be defined a X-Offset, Y-Offset and Z-Offset.

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

<p><a name="F2"></a></p>
  <h2>LN PT Direct. [Length,Rot.Angle,TiltAngle]</h2>

Line parallel to vector or line or tangential to circle or curve.
 Line by point and direction.
   Length     = length, optional.
   Rot.Angle  = rotation-agle, counterclockwise, optional.
   Tilt Angle = tilt-angle, counterclockwise, optional.

 Line by point with a fixed angle
 L3 = P1 ANG (45)

 By point line with the direction (vector):
 Parallel to line L1
 L4 = P1 D (L1)

 Line by point and the Z-axis of circle / level:
 L = PC
 L = PR

 Line by point with angle relative to the other line.
 ANG (0): parallel line L1; ANG (90): normal.
 L4 = P1 D (L1) ANG (90) 



<a name="F3"></a>
  <h2>LN LN Dist.          (parall)</h2>
Line parallel to line spacing.

L # = ParallelLine spacing [position]

  ParallelLine: select line, polygon.

  Position: Page Up / Page Down button;
     no value: left;
     1, 2 lateral right / left;
     3, 4 top / bottom 
 
 In addition to L1, distance 10, above L1:
 L8 = L1 VAL (10) MOD (3) 
 
 

 <a name="F4"></a>
  <h2>LN LN LN [Rotate Tilt] (mid)</h2>
 Mainly as a midline / diagonal line, in addition to rotation.
   The line is a diagonal line through the intersection;
   In parallel lines is a middle line.
   [Rotation, tilt angle] []
 
 As a diagonal line 
 L9 = L1 L2 
 
 As a diagonal line to 90 degrees 
 L9 = L1 L2 ANG (90) 
 
 
 
 <a name="F5"></a>
 <h2>LN CirTang Direct. [Rotate]</h2>
 Line tangent to a circle, with a defined direction, in addition to rotation
  Page (1 = right, 2 = left) 

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


 <a name="F6"></a>
  <h2>LN CirTang PT</h2>
 Line tangent to the specified point.
  Page (1 = right, 2 = left) 
 
 L1 = C1 P1 MOD (1)
 
 
 
<a name="F7"></a>
  <h2>LN CirTang CirTang</h2>
 Line tangent to 2 circles 
  Page (1 = right, 2 = left)
 
 L5 = C1 C2 MOD (1)
