C# Syntax

ConstructionHistory rtn = Primitive.ConstructionHistory;

Examples

VBScript Example

'
' This example illustrates how to search an object construction history
' for a particular operator
'
NewScene , false
set oObject = Application.ActiveProject.ActiveScene.Root.AddGeometry("Sphere","MeshSurface")
ApplyOp "Twist", oObject
ApplyOp "Bend", oObject
ApplyOp "Taper", oObject


' Find all operators reading from the primitive
set oPrimitive = oObject.ActivePrimitive
set oConstructionHistory = oPrimitive.ConstructionHistory

Application.LogMessage "The " & oObject.Name & " has the following operators applied"
for each oOperator in oConstructionHistory
   Application.LogMessage vbTab & oOperator.Type
next

set oTwistOperators = oConstructionHistory.Filter( "twistop" )

if oTwistOperators.Count = 1 then
   Application.LogMessage "There is 1 twist applied to " & oObject.Name & " and the twist angle is set to " _
       & oTwistOperators(0).angle.Value & " degrees"
else
   Application.LogMessage "There are " & oTwistOperators.Count & " twists applied to " & oObject.Name
end if

' Expected results:
'INFO : The sphere has the following operators applied
'INFO :  secondaryshapemarker
'INFO :  animationmarker
'INFO :  shapemarker
'INFO :  modelingmarker
'INFO :  taperop
'INFO :  bendop
