LWUNITS does not affect when using DataExtraction

ProfWolfMan — Mon, 11 May 2015 00:56:06 GMT

Hi All,

LWUNITS system variable does not affect the lineweight property value when dumping object's properties using DataExtraction(AcDX.dll).

I am using the following code part to extract properties of all objects in model space.

Before extracting, i set LWUNITS to 0 (inches).
But the result in dt_temp, shows values in mm.

Please share your experiences or any guidence to solve this issue.

'in this case LwUnits is zero(0)
 Application.SetSystemVariable("LWUNITS", CInt(LwUnits))
        Dim acDoc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument
        Dim acDocDb As Database = acDoc.Database
        Dim acDocEd As Autodesk.AutoCAD.EditorInput.Editor = acDoc.Editor
        Dim es As IDxExtractionSettings = New DxExtractionSettings()

        Dim de As IDxDrawingDataExtractor = es.DrawingDataExtractor
        de.Settings.ExtractFlags = ExtractFlags.ModelSpaceOnly

        Dim fr As IDxFileReference = New DxFileReference(System.IO.Path.GetDirectoryName(file), file)

        de.Settings.DrawingList.AddFile(fr)

        de.DiscoverTypesAndProperties(System.IO.Path.GetDirectoryName(file))
        'find all types and properties
        Dim types As List(Of IDxTypeDescriptor) = de.DiscoveredTypesAndProperties

        Dim selTypes As New List(Of String)
        Dim selProps As New List(Of String)
        'add all types
        For Each Type As IDxTypeDescriptor In types
            selTypes.Add(Type.GlobalName)
        Next
        'Add required properties to extract
        selProps.Add("Layer")
        selProps.Add("Color")
        selProps.Add("Linetype")
        selProps.Add("LineWeight")
        selProps.Add("Height")
        selProps.Add("TextStyleName")
        de.Settings.SetSelectedTypesAndProperties(types, selTypes, selProps)
        de.ExtractData(file) 'Extracting here
        Dim dtemp As System.Data.DataTable = de.ExtractedData 'extracted result

Hi,

I can reproduce the behavior I'm checking with Engineering.
