Hi everyone,

In my C# addin, I limit some command to some document type:

public int Command1Enable()
{
    var doc = (ModelDoc2)App.ActiveDoc;
    if (doc != null)
    {
        var type = (swDocumentTypes_e)doc.GetType();
        if (type == swDocumentTypes_e.swDocPART)
        {
            return 1;
        }
    }
    return 0;
}

Everything works great, when I switch between different document types (Ctrl+Tab), Command1 button state is updated.

... Until I create a new drawing doc:

After that, when I switch between different document types (Ctrl+Tab), Command1 button state is no longer updated.

Do you have the problem too?

SolidWorks 2017 SP2.
