Appends an outer loop to the hatch.
Supported platforms: Windows only
VBA:
object.AppendOuterLoop loop
Type: Hatch
The object this method applies to.
Access: Input-only
Type: Variant (array of Arc, Circle, Ellipse, Line, Polyline, Region, Spline objects)
An array of objects forming a closed boundary. The array can consist of one or more objects. If more than one object is used, their endpoints must coincide for the loop to be created properly.
No return value.
After the Hatch object has been created using the AddHatch method, add the outer loop. The outer loop must be closed and must be created before any inner loops can be added. After a valid outer loop has been created, add any inner loops, one at a time, using the AppendInnerLoop method.
Once you have finished defining the boundaries for the hatch, use the Evaluate method to calculate the hatch lines or fill for the boundaries, then use the Regen method to update the display of the hatch.
VBA:
Sub Example_AppendOuterLoop() ' This example creates an associative hatch in model space, and then creates an outer loop for the hatch. Dim hatchObj As AcadHatch Dim patternName As String Dim PatternType As Long Dim bAssociativity As Boolean ' Define the hatch patternName = "ANSI31" PatternType = 0 bAssociativity = True ' Create the associative Hatch object Set hatchObj = ThisDrawing.ModelSpace.AddHatch(PatternType, patternName, bAssociativity) ' Create the outer loop for the hatch. ' An arc and a line are used to create a closed loop. Dim outerLoop(0 To 1) As AcadEntity Dim center(0 To 2) As Double Dim radius As Double Dim startAngle As Double Dim endAngle As Double center(0) = 5: center(1) = 3: center(2) = 0 radius = 1 startAngle = 0 endAngle = 3.141592 Set outerLoop(0) = ThisDrawing.ModelSpace.AddArc(center, radius, startAngle, endAngle) Set outerLoop(1) = ThisDrawing.ModelSpace.AddLine(outerLoop(0).startPoint, outerLoop(0).endPoint) ' Append the outer loop to the hatch object, and display the hatch hatchObj.AppendOuterLoop (outerLoop) hatchObj.Evaluate ZoomAll End Sub
