How to unload a C# addin dll without exiting Microstation. I have tried mdl unload and the dll does not unload.

IS there any way to unload the program without exiting Microstation?

Microstation VBA - calling mdl function - mdlSurface_extractExtrusion

Jim Johnson — Tue, 08 Mar 2016 11:41:45 GMT

Hi,

I have a type 18 suface element that contains two line strings (and a lot of other line element that I'm not interested in) that are being used to represent railway rails in a 3d drawing. I've been trying to extract the line string information from the surface in vba, but there doesn't appear to be much support for surfaces in the vba / com interface, so I've ended trying the get the line information out by the calling the mdl function "mdlSurface_extractExtrusion". (I arrived at this function after poking round and reading other posts on these forums of a similar nature).

The mdl function appears to be getting called correctly but I'm getting -105 (MDLERR_BADELEMENT) as the return value. The distance variable reference that is passed to the mdl function also gets updated after the function call, so I think I'm almost there. I just can't figure out what I need to do to fix it?

Is mdlSurface_extractExtrusion the correct function to call to get the line string out of a this surface?

The direction point3d that I'm passing into the function is a point above the surface. I've noticed that in the mdl reference the distance parameter in the mdl function call is a 3d vector but in the vba wrapper offered in the mdl reference, it is declared as point 3d so assume that the vector angle is truncated in the conversion to point3d. Don't know if that is important or not though?

Any help or pointing in the right direction would be greatly appreciated.

Thanks

Jim

My code looks like this:

Declare Function mdlSurface_extractExtrusion Lib "stdmdlbltin.dll" (ByRef edPP As Long, ByRef directionP As Point3d, ByRef distanceP As Double, ByVal surfaceEdP As Long) As Long

Sub DumpSurfaceDetails()
    Dim elements As ElementEnumerator
    Set elements = ActiveModelReference.GetSelectedElements
    
    While elements.MoveNext
        If elements.Current.Type = 18 Then
            
            Dim elementDescPtr As Long
            elementDescPtr = elements.Current.MdlElementDescrP(False)
            
            Dim distance As Double
            distance = 10
            
            Dim direction As Point3d
            direction = Application.Point3dFromXYZ(150752.8186, 443929.0342, 22.9228)
            
            Dim returnedPointer As Long
            Dim success As Long
            success = mdlSurface_extractExtrusion(returnedPointer, direction, distance, (elementDescPtr))
            
            If returnedPointer > 0 Then
                Dim element As element
                Set element = MdlCreateElementFromElementDescrP(returnedPointer)
            End If
        End If
    Wend
    
End Sub

Is it possible to recover cells that have been dropped to graphics?
