Using iLogic to Export faces

[m_griffin2WHPP]

I am trying to build some files that are slightly more automated using iLogic and VBA, and I would like for someone to tell me what I am doing wrong. 

Why doesn't it work when you want to generate a .DXF file, its almost like the software is incapable of handling this request. So I am uncertain why an Autodesk Product cannot do this simple operation. 

Here is my sample code that is not working. 

If someone could run this code, and tell me about the class part of it. I am also running Attribute helper and if there is something I should do in VBA or iLogic. Please reach out to me, I would love to see this Automated.

I would like to use entities instead of attributes. 

Thank you

There is no SaveAsDXF Property or Method under the PartDocument Object.
I think you're looking for the ControlDefinition "GeomToDXFCommand" to "Export Face as" command

here's a relevant link that exports faces to DXF based on named entities

Do you have any sample code of this instance that I can modify?

Okay you have to try this, I actually got it to work based on that snippet you provided. 

Here is what you have to do, run this code by selecting the face that you want to set to be exported and giving it a named attribute.

'ATTRIBUTE FACES

---------------------------------------------------

' Ensure there is an object in the SelectSet

If ThisApplication.ActiveDocument.SelectSet.Count > 0 Then

    ' Get the first item in the SelectSet

    Dim oFace As Face

    oFace = ThisApplication.ActiveDocument.SelectSet(1)

    ' Check if the object is a Face

    If TypeOf oFace Is Face Then

        ' Check if the "ExportName" attribute set already exists

        Dim oAttrSet As AttributeSet

        If oFace.AttributeSets.NameIsUsed("ExportName") Then

            ' Use the existing attribute set

            oAttrSet = oFace.AttributeSets.Item("ExportName")

        Else

            ' Create a new attribute set

            oAttrSet = oFace.AttributeSets.Add("ExportName")

        End If

        ' Check if the "Name" attribute exists, otherwise add it

        If oAttrSet.NameIsUsed("Name") Then

            oAttrSet.Item("Name").Value = "MyFaceName"

        Else

            ' Add the "Name" attribute with the string type specified

            oAttrSet.Add("Name", ValueTypeEnum.kStringType, "MyFaceName")

        End If

        MessageBox.Show("Attribute 'Name' set to 'MyFaceName' for the selected face.", "Success")

    Else

        MessageBox.Show("The selected item is not a face.", "Error")

    End If

Else

    MessageBox.Show("No face selected. Please select a face and try again.", "Error")

End If

--------------------------------------------

Then run this rule and it will cycle through all those set faces with attributes and export the faces. 

' Define the export folder path

Dim exportFolder As String

exportFolder = "K:\Michael Griffin\My Drive\EXPORT\"

' Get the active document as a PartDocument

Dim oDoc As PartDocument

oDoc = ThisApplication.ActiveDocument

' Ensure the document is a part document

If oDoc.DocumentType = DocumentTypeEnum.kPartDocumentObject Then

    ' Iterate through each face in the surface bodies

    Dim oFace As Face

    For Each oFace In oDoc.ComponentDefinition.SurfaceBodies(1).Faces

        ' Check if the face has an attribute set named "ExportName"

        If oFace.AttributeSets.NameIsUsed("ExportName") Then

            ' Get the attribute value, which will be used as the filename

            Dim exportName As String

            exportName = oFace.AttributeSets.Item("ExportName").Item("Name").Value

            ' Prepare the file path for the DXF export

            Dim dxfFilePath As String

            dxfFilePath = exportFolder & exportName & ".dxf"

            ' Set up the GeomToDXFCommand for exporting the face

            Dim exportCommand As ControlDefinition

            exportCommand = ThisApplication.CommandManager.ControlDefinitions("GeomToDXFCommand")

            ' Select the face and activate the export command

            oDoc.SelectSet.Clear()

            oDoc.SelectSet.Select(oFace)

            ' Execute the export command for the selected face

            exportCommand.Execute

            ' Save the document as DXF to the specified file path

            oDoc.SaveAs(dxfFilePath, True)

            MessageBox.Show("Exported face '" & exportName & "' to DXF at " & dxfFilePath, "Success")

        End If

    Next

Else

    ' Display an error if the document is not a part document

    MessageBox.Show("This rule only works with part documents (.ipt files).", "Error")

End If

-----------------------------------------------------------

I actually got it to work, but not in the way that I thought it was going to bulk work, you still need to name them individually, but from a manufacturing standpoint this is probably the best method in doing that. My experience using Automation is that there is no one click solves all button. It is all about the small victories. 

Thanks for you help!

End If

[jnowel]

just wondering, why still use the "SaveAs" Method?

[m_griffin2WHPP]

When filling job orders we are taking the same model and making changes to it and will need the faces to write G code for various machines in the shop. The operators need these naming schemes to carry out checks and balances when I make mistake. 

THANKS!!!!!!!!

[marcin_otręba]

Hi, you can give name using  PostPrivateEvent

Call ThisApplication.CommandManager.PostPrivateEvent(PrivateEventTypeEnum.kFileNameEvent, yourname & ".dxf")

yourname should be full file name containing full path

for example:

Call ThisApplication.CommandManager.PostPrivateEvent(PrivateEventTypeEnum.kFileNameEvent, path & oDoc.PropertySets(3)("Part Number").value & ".dxf")

before

 exportCommand.Execute

@m_griffin2WHPP 

Here is another approach that might work for you. 

We use this for unwrapped surfaces, a couple of advantages with this method.

- You can unwrap the same surface multiple times and name the unwrapped surface bodies differently. This gets around the limitation of only one named entity for a face. 

- You can then orient the surface body with respect to the UCS (if this is a requirement for you), flip, mirror, rotate. The exported surface will take its orientation from the UCS. 

Take a look at the below, you would need to add your logic for processing multiple surfaces and parts, but it should be pretty easy. 

Sub Main()
Dim oDoc As Document = ThisDoc.Document

ThisApplication.StatusBarText = "Select a Unfolded Surface to Export as DXF"
Dim entity = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kPartFaceFilter, "Select a Unfolded Surface to Export as DXF")
oDoc.SelectSet.Select(entity)

Dim oFace As Face
oFace = oDoc.SelectSet(1)
If Not oFace.SurfaceType = SurfaceTypeEnum.kPlaneSurface Then
	MessageBox.Show("A planar face must be selected, the rule will exit", "Error Handling")
	Return
End If

strDxfTextLine1 = "Text Line 1"
strDxfTextLine2 = "Text Line 2"
strDxfTextLine3 = "Text Line 3"
strDxfTextLine4 = "Text Line 4"
strDxfTextLine5 = "Text Line 5"

DXF_FileName = ThisDoc.PathAndFileName(False) & ".dxf"

Call Process_oSB_DXF(oFace, oDoc, DXF_FileName, strDxfTextLine1, strDxfTextLine2, strDxfTextLine3, strDxfTextLine4, strDxfTextLine5)

End Sub
		

Sub Process_oSB_DXF(oFace As Face, oDoc As PartDocument, DXF_FileName As String, strDxfTextLine1 As String, strDxfTextLine2 As String, strDxfTextLine3 As String, strDxfTextLine4 As String, strDxfTextLine5 As String)
