Fragmented DXF Edge

Hello

We use a macro that makes the unfolded DXF of sheet metal part. This works well but the sheet metal edges are fragmented on the DXF at each bend (see attached image). This problem hinders the programming of our punching machine.

Do you know a solution to avoid this problem?

Thanks in advance

Hello

When you are in the room and you deploy the unfolded function you have a second function and on this one you do a right click and vor if the merge the stops box (something like that because I am not in front of my PC) and uncheck. If this is the case, check this box and do a test and if it is conclusive, you will have to re-register your part models with these parameters.

Thank you for this answer,

This solution works well, but it will be necessary to redo the handling for each existing part. Are there more systematic solutions? (Parameter in the options ; function on the DXF generation macro; modification of this parameter in bulk ; ... ?)

In fact, if you save your part model, it will be good for new creations, but for old parts, normally your programming department should have the old files that they have modified so that they can be used.

The majority of the pieces we create are copies of existing parts, so the problem will remain.

Ok but if you take back existing parts it will make you two more clicks to modify it so that the dxf does not pose too much of a problem to the programming department.

Hello

You can add the modification of this parameter at the beginning of the macro, look HERE , you should find what you need (IModelDocExtension::SetUserPreference...) with the examples that go well.

Kind regards

Grasse has all your answers, I found IFlatPatternFeatureData with the MergeFace property.

I have to look at how this works, but it seems possible to integrate it into my macro.

Hello

To test with us can you ask a piece and the macro.

may the force be with you.

Thanks to your answers, a bit of research and racking my brains I made a macro that modifies the value of 'merge faces' of the unfolded state (or swFlatPatternFeatureData.MergeFace). 

Thank you for your help

Sub main()
    
    Dim SwApp                       As SldWorks.SldWorks
    Dim Part                        As SldWorks.ModelDoc2
    Dim boolstatus                  As Boolean
    Dim swFeature                   As SldWorks.Feature
    Dim swFlatPatternFeatureData    As SldWorks.FlatPatternFeatureData
    
    Set SwApp = Application.SldWorks
    
    Set Part = SwApp.ActiveDoc
    Set swFeature = Part.FirstFeature
    While Not swFeature Is Nothing
        If swFeature.GetTypeName = "FlatPattern" Then
            
            Set swFlatPatternFeatureData = swFeature.GetDefinition
            
            If swFlatPatternFeatureData.MergeFace = 1 Then
                swFlatPatternFeatureData.MergeFace = False
            Else
                swFlatPatternFeatureData.MergeFace = True
            End If
            
        boolstatus = swFeature.ModifyDefinition(swFlatPatternFeatureData, Part, Nothing)
        
        End If
        Set swFeature = swFeature.GetNextFeature
    Wend

End Sub
