How to SaveAs part and replace all instances in open documents

Hello Guys!

Bummer... I`m trying to replace part in the assembly with same part with a different name. The idea is:

1. open Assembly document  - works

2. save it as with a new name - works

' opening  assembly

        swModel = swApp.OpenDoc6(".....path.....PLENUMASSY.SLDASM", swDocumentTypes_e.swDocASSEMBLY,

                                 swOpenDocOptions_e.swOpenDocOptions_ReadOnly, "", fileerror, filewarning)

        swModel = swApp.ActiveDoc

        ' saving Assembly model AS new A#

        boolstatus = swModel.Extension.SaveAs(My.Settings.LastSaveADir + txt_AssNum.Text.Trim + ".sldasm", 0, swSaveAsOptions_e.swSaveAsOptions_Silent, Nothing, fileerror, filewarning)

3. assembly has 4 parts, so I`m trying to open first part - works

        'opening top plenum part

        swPartModel = swApp.OpenDoc6(".....path....PLTRIMTOP.SLDPRT", swDocumentTypes_e.swDocPART,

                                 swOpenDocOptions_e.swOpenDocOptions_ReadOnly, "", fileerror, filewarning) 'open part file as read only

        swPartModel = swApp.ActiveDoc

        ' saving files

        boolstatus = swPartModel.Extension.SaveAs(My.Settings.LastSaveMDir + txt_Part1.Text.Trim + ".sldprt", 0, swSaveAsOptions_e.swSaveAsOptions_Silent, Nothing, fileerror, filewarning) ' saves assembly

So its saves the part in the directory but it doesn replaces it in the active assembly.... Like if you do it manually in SW you click save as and you choose to replace all parts in all open assemblies.... is there a way to do that programmatically?

I guess the other question if this is not possible, can someone give me an example of the code that chooses certain part (lets say PLTRIMTOP.SLDPRT) in the active assembly and replaces it with a different part? I know how to replace

boolstatus = swAssy.ReplaceComponents(My.Settings.LastSaveMDir + txt_Part1.Text.Trim + ".sldprt", "", True, True)

but I`ve no idea how to choose specific part.

Any help is appreciated.

Thanks,

Alex
