I am using the macro from this thread:

https://www.eng-tips.com/viewthread.cfm?qid=328477...

Changed a little bit into this:

Option Explicit

Sub main()

Dim swApp As SldWorks.SldWorks
Dim swModel As SldWorks.ModelDoc2
Dim vConfNameArr As Variant
Dim sConfigName As String
Dim nStart As Single
Dim i As Long
Dim bShowConfig As Boolean
Dim bRebuild As Boolean
Dim bRet As Boolean


Set swApp = CreateObject("SldWorks.Application")
Set swModel = swApp.ActiveDoc

vConfNameArr = swModel.GetConfigurationNames

For i = 0 To UBound(vConfNameArr)

sConfigName = vConfNameArr(i)


bShowConfig = swModel.ShowConfiguration2(sConfigName)

bRebuild = swModel.ForceRebuild3(False)

Dim FilePath As String
Dim PathSize As Long
Dim PathNoExtension As String
Dim NewFilePath As String

FilePath = swModel.GetPathName
PathSize = Strings.Len(FilePath)
PathNoExtension = Strings.Left(FilePath, PathSize - 6)

NewFilePath = sConfigName & ".DXF"

'Export Flat Pattern
bRet = swModel.ExportFlatPatternView(NewFilePath, 1)

Next i

End Sub

Now the problem I have with this is:
When before running the macro (in Solidworks 2020) I save a random drawing, my export macro uses the scale of that drawing to export the dxf.
So I save a drawing with scale 1:2
I run the macro in part environment
The part is for example 100x100mm
The exported dxf has dimensions 200x200.

Ofcourse I want to export only 1:1, independend of the non related drawings I save.

Thanks for any help.
