Parameters

Reversed

True to reverse the variable-pitch helix, false to not

Clockwise

True to create the variable-pitch helix in a clockwise direction, false to create in a counter-clockwise direction

Helixdef

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

• swHelixDefinedByPitchAndRevolution

• swHelixDefinedByHeightandRevolution

• swHelixDefinedByHeightAndPitch

Startangle

Angle at which to start the variable-pitch helix

Return Value

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.
