Access modifiers aren't that much important, unless you need the command method itself elsewhere (in your app, not just as an AutoCAD command). Btw. you do NOT show your forms in AutoCAD by Form.Show() method, 'cause it'll most likely crash. Use Application.ShowModalDialog(...) or ShowModelessDialog(...) methods in Autodesk.AutoCad.ApplicationServices namespace..
