Hi,

I have a problem. I want to create a Mate constraint between WorkPlane and McadPoint. I wrote this code:

Dim Patty As McadComponent
Set Patty=mcad.ActiveDocument.AssemblyMgr.RootDefinition.Children(0)

    Dim Wplane As McadPlane, wpFeat As McadFeature,anyWP As McadPlane
    For Each anyWP In Patty.definition.body.WorkPlanes
        For Each wpFeat In anyWP.GetFeatures
            If wpFeat.name Like "*Base#*" Or wpFeat.name Like "*base#*" Then
               Set Wplane = anyWP: GoTo exF
            End If
        Next
    Next
exF:
Dim pt As McadPoint
Dim utM As McadUtility
Set ut = ThisDrawing.Application.GetInterfaceObject("mcad.Application").ActiveDocument.Utility
Dim Val As McadValue: Set Val = ut.CreateValue

'------------------'
'                  '
'      CODE        '
'                  '
'------------------'
Dim C2 As IMcadGeometry: Set C2 = Wplane

Dim dM1 As McadConstraintDescriptor: Set dM1 = ut.CreateConstraintDescriptor(mcCompMate)
dM1.Operand1 = pt: dM1.Operand1Orientation = mcRaw: dM1.Operand2 = C2: dM1.Operand2Orientation = mcRaw
dM1.Value = Val
Dim M1 As McadComponentConstraint: Set M1 = kt.AddConstraint(dM1)

When I try to create a new constraint I get an error: -2147196502(800461aa) "Generic Failure to executo operation with provide arguments". I have to select WorkPlane without Pick.

Please, help me!

Thanks!
