Extend Sketch Entity Example (VBA)

This example shows how to extend a selected sketch entity (e.g., line, segment, or arc) to meet another sketch entity.

' Preconditions: Open a part document.
' Postconditions:
' 1. A new sketch is inserted.
' 2. Two non-parallel lines are created.
' 3. The first line is extended to meet the second line.

Option Explicit

Dim swApp As SldWorks.SldWorks
Dim swModel As SldWorks.ModelDoc2
Dim swModelDocExt As SldWorks.ModelDocExtension
Dim swSketchMgr As SldWorks.SketchManager
Dim boolstatus As Boolean

Sub main()

    Set swApp = Application.SldWorks
    Set swModel = swApp.ActiveDoc
    Set swModelDocExt = swModel.Extension
    Set swSketchMgr = swModel.SketchManager

    swSketchMgr.InsertSketch False

    ' Create two non-parallel lines
    swSketchMgr.CreateLine -0.5, 0.88, 0#, -0.21, -0.13, 0#
    swSketchMgr.CreateLine -0.75, -1.128, 0#, 0.41, -1.128, 0#

    ' Set the selection mode to default

    ' Select the sketch line to extend
    boolstatus = swModelDocExt.SelectByID2("Line1", "SKETCHSEGMENT", 0#, 0#, 0#, False, 0, Nothing, 0)

    ' Extend the selected sketch line to meet the second line
    boolstatus = swSketchMgr.SketchExtend(0#, 0#, 0#)

    swSketchMgr.InsertSketch True

End Sub
