Get Sketch Constraints Example (VBA)

This examples shows how to determine whether or not a sketch is under-constrained or over-constrained and how to iterate over all the entities in the sketch and list their constraints.




' Preconditions:

'       (1) Part or assembly is open.

'       (2) Sketch is selected.


' Postconditions: None


' NOTE: To access sketch-segment constraint

'       information, the sketch must be placed into

'       edit mode.



Option Explicit


Sub main()

    Dim swApp               As SldWorks.SldWorks

    Dim swModel             As SldWorks.ModelDoc2

    Dim swSelMgr            As SldWorks.SelectionMgr

    Dim swFeat              As SldWorks.feature

    Dim swSketch            As SldWorks.sketch

    Dim vSketchSeg          As Variant

    Dim vConstraint         As Variant


    Dim i                   As Long

    Dim j                   As Long

    Dim bRet                As Boolean


    Set swApp = Application.SldWorks

    Set swModel = swApp.ActiveDoc

    Set swSelMgr = swModel.SelectionManager

    Set swFeat = swSelMgr.GetSelectedObject5(1)

    Set swSketch = swFeat.GetSpecificFeature2


    Debug.Print "Sketch = " & swFeat.Name

    Debug.Print "  SketchConstraintStatus = " & swSketch.GetConstrainedStatus

    Debug.Print ""


    ' Put sketch into edit mode to get access

    ' to sketch segment constraint information



    vSketchSeg = swSketch.GetSketchSegments


    For i = 0 To UBound(vSketchSeg)

        vConstraint = vSketchSeg(i).GetConstraints

        For j = 0 To UBound(vConstraint)

            Debug.Print "  SketchSegConstraint[" & i & "] = " & vConstraint(j)

        Next j

    Next i


    ' Exit edit mode and do not rebuild the model

    swModel.InsertSketch2 False

End Sub
