Storing and restoring temp body in 3rd party storage using SOLIDWORKS API

This VBA example demonstrates how to store the copy of the selected body in the new document's stream and restore and display the body on model opening.

Body is serialized and deserialized from the 3rd party storage.

  • Create new macro and add new form. Name it UserForm1 (default name)
  • Add the button. Specify the caption Store Body and name cmdStoreBody as shown below

Macro tree and user form controls{ width=450 }

  • Paste the following into the user form's code behind:
Const BODY_STREAM_NAME = "_CodeStackBody_"

Dim WithEvents swApp As SldWorks.SldWorks
Dim swModeler As SldWorks.Modeler
Dim WithEvents swCurPart As SldWorks.PartDoc
Dim swCurBody As SldWorks.Body2

Private Sub UserForm_Initialize()

Set swApp = Application.SldWorks
Set swModeler = swApp.GetModeler

End Sub

Private Function swApp_DocumentLoadNotify(ByVal docTitle As String, ByVal docPath As String) As Long

If docPath <> "" Then

Dim swModel As SldWorks.ModelDoc2
Set swModel = swApp.GetOpenDocumentByName(docPath)

If TypeOf swModel Is SldWorks.PartDoc Then
Set swCurPart = swModel
End If

End If

End Function

Private Function swCurPart_LoadFromStorageNotify() As Long
DisplayBodyFromStream
swCurPart_LoadFromStorageNotify = 0
End Function

Private Function swCurPart_SaveToStorageNotify() As Long

If Not swCurBody Is Nothing Then
StoreBodyToStream
MsgBox "Body is stored to the model stream. Close and reopen the model to restore the body"
End If

swCurPart_SaveToStorageNotify = 0

End Function

Private Sub cmdStoreBody_Click()

Dim swModel As SldWorks.ModelDoc2
Set swModel = swApp.ActiveDoc

Dim swSelMgr As SldWorks.SelectionMgr
Set swSelMgr = swModel.SelectionManager

Set swCurBody = swSelMgr.GetSelectedObject6(1, -1)

If Not swCurBody Is Nothing Then
Set swCurBody = swCurBody.Copy
Dim partTemplate As String
partTemplate = swApp.GetUserPreferenceStringValue(swUserPreferenceStringValue_e.swDefaultTemplatePart)
Set swCurPart = swApp.NewDocument(partTemplate, swDwgPaperSizes_e.swDwgPapersUserDefined, 0, 0)
MsgBox "Save this document to store the body in its stream"
Else
MsgBox "Please select body"
End If

End Sub

Sub DisplayBodyFromStream()

Dim swModel As SldWorks.ModelDoc2
Set swModel = swCurPart

Dim swStream As Variant
Set swStream = swModel.IGet3rdPartyStorage(BODY_STREAM_NAME, False)

If Not swStream Is Nothing Then

Set swCurBody = swModeler.Restore(swStream)
swModel.IRelease3rdPartyStorage BODY_STREAM_NAME
swCurBody.Display3 swModel, RGB(255, 255, 0), swTempBodySelectOptions_e.swTempBodySelectable

End If

End Sub

Sub StoreBodyToStream()

Dim swModel As SldWorks.ModelDoc2
Set swModel = swCurPart
Dim swStream As Variant
Set swStream = swModel.IGet3rdPartyStorage(BODY_STREAM_NAME, True)
swCurBody.Save swStream
swModel.IRelease3rdPartyStorage BODY_STREAM_NAME

End Sub
  • Insert the following code into the macro's main module:
Sub main()

UserForm1.Show vbModeless

End Sub

Running Macro

  • Start the macro from the main module. Note, if you run the macro when form is active in the macro editor - form will be displayed as modal window and will prevent selections and saving
  • Open any part document with any geometry
  • Select solid body from the tree and click Store Body in the user form
  • New part document is created and the following message is displayed: Save this document to store the body in its stream
  • Save this file. When file is saving the body from different part is serialized into the stream of new document and no longer related to the original body.
  • Once completed, the following message is displayed: Body is stored to the model stream. Close and reopen the model to restore the body
  • Now, close all documents and reopen the last saved file. The body is deserialized and displayed. Note, that there is no feature tree in the model.

Restored body{ width=350 }

  • You can close SOLIDWORKS session and reopen the model. The body will still be loaded. Note, you need to run the macro before opening the model.
