Solids Builder - Define Variable

Define Variable - creates a local variable, which only exists inside the Constructor, that is, it is not visible in the device properties:

The Define Variable activity has the following properties:

• Name - variable name
  It will be the name of the activity too
  You must respect the naming rules
• Visible Object - when the variable is a geometry (point, line, solid) it may or may not be drawn in the preview
• Variable Type
  • Double - real number
  • Int32 - integer (32 bits)
  • String - any text
  • Boolean - true/false
  • GeometryPoint - a point recognizable by the Constructor
  • GeometryVector - a Constructor recognizable vector
  • GeometryPLine - a Constructor recognizable polyline
  • GeometryCurve - a curve (line, arc...) recognizable by the Constructor
  • GeometrySolid - a solid recognizable by the Constructor
• Value - Expression to be evaluated that results in an object of the type specified in 'Variable Type'
  Any value, Visual Basic expression that is evaluated for the informed type, examples:
  • Double: 0.5 (the decimal separator is the dot (.))
  • Int32: 54
  • String: "TEXT"
  • VB Expressions:
    • Width + Wall
      Assuming they are two variables or parameters
    • Line.StartPoint
      assuming that Line is an GeometryCurve
    • Math.Cos(Angle)
      Assuming that Angle is a variable that contains an angle given in radians
    • True
      Assuming the type is a Boolean
    • A*X^2+B*X*C
      Equations must be well written! (the above equation is different from: A*x² + B*x + C)
