Solids Builder - Points

Points are the most basic geometry you can draw. They will be used to create more complex geometries. There are the following activities that create points:

• Point (XYZ) - creates points based on their absolute X, Y, Z coordinates or relative to another known point
• Point (Distance/Angle) - creates a point from a known point, given a horizontal distance, a counterclockwise angle starting from the X axis, and a dimension difference
• Point on Curve - calculates a point that is on a curve
• Point/Bulge - creates a 2D point that has the Convexity property, for creating polylines with arcs
• Point/Bulge (radius) -creates a 2D point that has the Convexity property, to create polylines with arcs, given the radius
• Intersection (4 points) - calculates the intersection between two lines passing through the specified points
• Line Intersection - calculates the intersection between two lines
• Calculate Target - calculates a point on a curve based on a reference axis

Properties (to be used in VB expressions)

• X - ordinate X, real number
• Y - ordinate Y, real number
• Z - Z ordinate, real number

Methods (to be used in VB expressions):

• DistanceTo - calculates the 3D distance to another point
  distance = PT1.DistanceTo(PT2)
  where PT1 and PT2 are points and the distance will be a real number
  
  
• Distance2D - calculates the 2D distance to another point
  distance = PT1.DistanceTo(PT2)
  where PT1 and PT2 are points and the distance will be a real number
• Polar - calculates a point given angle, distance and an elevation difference
  PT2 = PT1. Polar(angle, distance, deltaz)
  where PT1 and PT2 are points
  angle in radians
  distance and deltaz are real numbers
  
  
• New - creates a new instance of a point
  pt =New GeometryPoint(x, y, z)
  Where x, y, z are real numbers
  
  
• CompareTo compares the point to another object
  value = pt.compareTo(obj)
  Where:
  pt, is a point
  obj, is anything
  value will be an integer:
  • 0, indicates obj is a point in the same coordinates as pt
  • -1, indicates that obj is not a period
  • 1, indicates that obj is a point, but does not match pt
• Add - adds an offset (see too) to the point and creates another point
  pb = pa.Add(vector)
  Where:
  pa and pb are points
  vector is a vector
