Transform Point from Component Space to Assembly Space Example (VBA)

This example shows how to transform a point from component space to assembly space.

 

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

'

' Preconditions:

'       (1) Assembly document is open.

'       (2) Component is selected.

'

' Postconditions: Component's origin is transformed to a point assembly space.

'

Sub main()

    Dim swApp                   As SldWorks.SldWorks

    Dim swMathUtil              As SldWorks.MathUtility

    Dim swModel                 As SldWorks.ModelDoc2

    Dim swSelMgr                As SldWorks.SelectionMgr

    Dim swComp                  As SldWorks.Component2

    Dim swXform                 As SldWorks.MathTransform

    Dim nPt(2)                  As Double

    Dim vPt                     As Variant

    Dim swPt                    As SldWorks.MathPoint

    Dim i                       As Long

    Dim bRet                    As Boolean

    Set swMathUtil = swApp.GetMathUtility

    Set swModel = swApp.ActiveDoc

    Set swSelMgr = swModel.SelectionManager

    Set swComp = swSelMgr.GetSelectedObjectsComponent(1)

    Set swXform = swComp.Transform2

    

    ' Point at component origin

    nPt(0) = 0#

    nPt(1) = 0#

    nPt(2) = 0#

    vPt = nPt

    

    Set swPt = swMathUtil.CreatePoint(vPt)

    Set swPt = swPt.MultiplyTransform(swXform)

    Debug.Print "  Comp = " & swComp.Name2 & " [" & swComp.GetPathName & "]"
