Remove Sketch Contour from Feature Example (VBA)

This example shows how to remove the first selected contour, which can be a sketch contour or sketch region, from an extrude feature made up of multiple sketch contours or sketch regions.

NOTE:  This same code will work for a revolve feature made up of multiple sketch contours or sketch regions in its base sketch if you modify IModelDocExtension::SelectByID2 and the variable ext.

 

'---------------------------------------

'

' Preconditions:

'          1) Part document is open.

'          2) Part contains a base sketch with multiple sketch contours or sketch

'             regions or both.

'          3) Extrude1 feature was created using sketch regions or

'             sketch contours of base sketch.

'

' Postconditions: None

Option Explicit

 

Dim swApp As SldWorks.SldWorks

Dim Part As SldWorks.ModelDoc2

Dim boolstatus As Boolean

 

Sub main()

 

Set swApp = Application.SldWorks

Set Part = swApp.ActiveDoc

boolstatus = Part.Extension.SelectByID2("Extrude1", "BODYFEATURE", 0, 0, 0, False, 0, Nothing, swSelectOptionDefault)

 

Dim feat As Feature

Dim ext As ExtrudeFeatureData2

Dim cts As Variant

Set feat = Part.SelectionManager.GetSelectedObject5(1)

Set ext = feat.GetDefinition

ext.AccessSelections Part, Nothing

 

' Get the selected contours in the feature

cts = ext.Contours

' Get the first selected contour in the feature and mark it

cts(0).Select False, 0

 

Dim cr As SketchRegion

Dim ct As SketchContour

 

' Determine if the first selected contour in the feature
' is either a sketch region or a sketch contour

If TypeOf cts(0) Is SketchRegion Then

    Set cr = cts(0)

Else

    Set ct = cts(0)

End If

 

' Assign Nothing to the first selected contour in the feature

Set cts(0) = Nothing

' Update the selected contours in the feature

ext.Contours = cts

' Modify the feature by removing the first selected contour in the feature

boolstatus = feat.ModifyDefinition(ext, Part, Nothing)

End Sub
