Application.CreateCurve method

Creates an instance of Curve object and optionally binds it to a document

Syntax:

Function CreateCurve(Optional ByVal Document As Document = Nothing) As Curve

Parameters:

Name	Type	Description
Document	Document	Specifies the settings to apply

Remarks:

The CreateCurve method creates a curve in memory and optionally binds it to a document.

Any changes made to the curve in memory do not affect the document, and are, therefore, performed very fast.

When you work with coordinates (for example, setting the position of a node, getting the length of a curve, and so on), it is important to know which document to reference. You can attach a curve in memory to a document to use that document's system of measurement. This can be done by specifying the optional Document parameter in the CreateCurve method, or by using the Curve.BindToDocument method.

Examples:

The following VBA example creates a curve on the active layer using the settings of the active document.

Sub Test()
  Dim crv As Curve
  Dim s As Shape
  Dim sp As SubPath
  Set crv = Application.CreateCurve(ActiveDocument)
  Set sp = crv.CreateSubPath(1, 5)
  sp.AppendLineSegment 2, 0
  sp.AppendCurveSegment2 5, 7, 6, 6, 3, 5
  sp.AppendCurveSegment2 7, 2, 3, 6, 7, 1
  sp.AppendLineSegment 9, 6
  sp.Nodes(3).Type = cdrSmoothNode
  Set s = ActiveLayer.CreateCurve(crv)
End Sub
You can also use the New keyword to create a curve in memory.
Dim crv As Curve
Set crv = New Curve
