.NET Syntax

Visual Basic (Declaration) 
Function InsertVariablePitchHelix( _
   ByVal Reversed As System.Boolean, _
   ByVal Clockwise As System.Boolean, _
   ByVal Helixdef As System.Integer, _
   ByVal Startangle As System.Double _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As IFeatureManager
Dim Reversed As System.Boolean
Dim Clockwise As System.Boolean
Dim Helixdef As System.Integer
Dim Startangle As System.Double
Dim value As System.Boolean
value = instance.InsertVariablePitchHelix(Reversed, Clockwise, Helixdef, Startangle)
System.bool InsertVariablePitchHelix( 
   System.bool Reversed,
   System.bool Clockwise,
   System.int Helixdef,
   System.double Startangle
System.bool InsertVariablePitchHelix( 
&   System.bool Reversed,
&   System.bool Clockwise,
&   System.int Helixdef,
&   System.double Startangle


True to reverse the variable-pitch helix, false to not
True to create the variable-pitch helix in a clockwise direction, false to create in a counter-clockwise direction

Definition of variable-pitch helix as defined in swHelixDefinedBy_e; valid enumerators are:

  • swHelixDefinedByPitchAndRevolution

  • swHelixDefinedByHeightandRevolution

  • swHelixDefinedByHeightAndPitch

Angle at which to start the variable-pitch helix

Return Value

True if the variable-pitch helix is started, false if not



To create and insert a variable-pitch helix, call:

  1. IFeatureManager::InsertVariablePitchHelix to create it.
  2. IFeatureManager::AddVariablePitchHelixFirstPitchAndDiamenter to add the first segment.
  3. IFeatureManager::AddVariablePitchHelixSegment one or more times to add the remaining segments.
  4. IFeatureManager::EndVariablePitchHelix to insert it.
