Occurence lose his origin-orientation after move his XY-Origin

[maurizio_manzi]

Hello,

occ1 (and its origin) should be moved in X and Y to the origin of occ2.
That works fine, but why does occ1 (its origin) then lose the rotation it had in the XY plane?

Best regards
Maurizio

if occ1 is not None and occ2 is not None:
            occ2.component.name = occ1.component.name
            des = adsk.fusion.Design.cast(app.activeProduct)
            isParametric = des.designType == adsk.fusion.DesignTypes.ParametricDesignType
            if isParametric == True:
                result = ui.messageBox(
                    moveOcc1ToOcc2Str, 
                    deleteConstructionHistoryStr, 
                    adsk.core.MessageBoxButtonTypes.OKCancelButtonType, 
                    adsk.core.MessageBoxIconTypes.QuestionIconType
                )
                if result == adsk.core.DialogResults.DialogOK:
                    des.designType = adsk.fusion.DesignTypes.DirectDesignType
                else:
                    ui.messageBox(moveOcc1ToOcc2ErrorStr)
            isParametric = des.designType == adsk.fusion.DesignTypes.ParametricDesignType
            if isParametric == False:
                zOld = occ1.transform.translation.z
                pt2 = occ2.transform.translation
                xTarget = pt2.x
                yTarget = pt2.y
                newTrans = adsk.core.Matrix3D.create()
                newTrans.translation = adsk.core.Vector3D.create(xTarget, yTarget, zOld)
                occ1.transform = newTrans
