Current AutoCAD Product vs. Drawing Authored Product (MEP, Arch, Vanilla, etc)

[Anonymous]

I am trying to find the actual product name or some other identification for the current AutoCAD product in which my .Net add-in is executing.  For example my add-in might load in 'Vanilla' AutoCAD or MEP or Architecture.  I would like to be able to detect if it is running in one of these products.  Similarly I would like to be able to detect this information from a drawing.  For example, I would like to write some logic to detect if a drawing authored in, say, MEP is being used in Architecture.

For the whole product this should do it:

Imports MgdAcApplication = Autodesk.AutoCAD.ApplicationServices.Application

Dim product As String = "ACAD: " + MgdAcApplication.Version.ToString + " PROD: " + MgdAcApplication.GetSystemVariable("PRODUCT").ToString

in my case this says: ACAD: 19.0.0.0 PROD: AutoCAD

There is also object level versioning embedded in every drawing database entity (Autodesk.AutoCAD.DatabaseServices.Entity) called ObjectBirthVersion

Dim dbObj As Autodesk.AutoCAD.DatabaseServices.DBObject = _

acTrans.GetObject(id, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForWrite)

Dim ent As Autodesk.AutoCAD.DatabaseServices.Entity = _

TryCast(dbObj, Autodesk.AutoCAD.DatabaseServices.Entity)

Dim objVersion As String = "ObjectBirthVersion: " + ent.ObjectBirthVersion.ToString

If you print this out:

 ObjectBirthVersion:     'AC1012,Release0'

Thanks for the reply and help finding the product in the application.  I am still missing the product for the drawing.  We want to warn the user if they are opening something like a MEP drawing in vanilla AutoCAD because objects won't contain the rich data they would in MEP.

You can find the drawing version info in the drawing Database under OriginalFileVersion:

Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database.OriginalFileVersion:

OriginalFileVersion = AC1024

This means: AutoCAD 2010, AutoCAD 2011, AutoCAD 2012

You can decode the version from the wiki page I linked in my original response.Not sure if this helps you but that's the only version info in the drawing I am aware of.

If you want to dig in yourself, the following code prints out all the available info in the drawing database.  You can use it for any object including the drawing itself:

Imports MgdAcApplication = Autodesk.AutoCAD.ApplicationServices.Application

Dim activeDoc As Document = MgdAcApplication.DocumentManager.MdiActiveDocument

Dim ed As Editor = activeDoc.Editor

Dim props As PropertyInfo() = activeDoc.GetType().GetProperties()

ed.WriteMessage(vbLf + "PROPS=" + props.Count.ToString)

Dim i As Int32 = 0

For Each p As System.Reflection.PropertyInfo In props

    Try

       ed.WriteMessage(vbLf + p.Name + "=" + p.GetValue(activeDoc, Nothing).ToString)

       i += 1

    Catch

       Dim msgStr As String = String.Format("ERR: '{0}' p='{1}'", Err.Description, p.ToString)

       ed.WriteMessage(vbLf + msgStr)

    End Try

Next

Thank you for your help.  I feel a bit embarrassed as I didn't notice the link to the wiki article.  In my defense the link looks like all the other page links so I probably just glossed it over.  Thank you for taking time to go through it!

Hi,

Vertical products (MEP, arch, ...) add ther own dictionaries to the NamedObjectDictionary which do not exist in Vanilla drawings. May be you can look this way...
