Solids Builder - Points

Points are the most basic geometries that can be drawn. 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 in relation to another known point
• Point (Distance/angle) - creates a point from a known point, given a horizontal distance, an counterclockwise angle starting on the X axis and an elevation difference
• Point on Curve - calculates a point that is on a curve
• Point/Bulge - creates a 2D point that has the Bulge property, for creating polylines with arcs
• Point/Bulge (radius) - creates a 2D point that has the Bulge property, for creating polylines with arcs, given radius
• Point Intersect (4 points) - calculates the intersection between two lines that pass through the specified points
• Curve Intersect - calculates the intersection between two curves

Properties (to be used in VB expressions)

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

Methods (to be used in VB expressions):

• DistanceTo - calculates 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 2D distance to another point that represents the distance between them in the XY plane
  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
  PT2 = PT1. Polar(angle, distance, deltaElevation)
  Where: PT1 and PT2 are points
  angle in radians
  distance and deltaElevation 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, it's a point
  obj, it's anything
  value will be an integer:
  • 0, indicates obj is a point at the same coordinates as pt
  • - 1, indicates that obj is not a point
  • 1, indicates that obj is a period, but does not match pt
• Add - add an offset (vector) to the point and create another point
  pb = pa. Add (vector)
  Where:
  pa and pb are points
  vector is a vector
