Creating Alignment throws "Alignment ID is invalid" error
Does an alignment with that name already exist? Do the alignment style and label set style exist? I seem to recall having issues when passing strings, all of my current code gets the appropriate ObjectIds for the objects to pass (Site, layer, style, styleset) and all works fine, including ObjectId.Null for the siteless alignments. Oh, and I also check for duplicate alignment name and change the new name to be unique by adding "(1)" to the provided named, which is what C3D does.
Felix, move the Alignment creation code out of the Command handler class. I created a small CommandMethod, using just your small bit of code to create the alignment and it works without error. Here's what one of our ribbon buttons looks like and the AdskCommandHandler that it calls, hopefully it will help you:
rb = new RibbonButton();
rb.Text = "Create\nAlign/Prof";
rb.CommandParameter = "_.CreateAlignProf ";
rb.ShowText = true;
rb.ShowImage = true;
rb.CommandHandler = new AdskCommandHandler();
rb.Orientation = System.Windows.Controls.Orientation.Vertical;
rb.Size = RibbonItemSize.Large;
rb.Image = SincpacC3D.cap_small.ToBitmapImageFromPng();
rb.LargeImage = SincpacC3D.cap.ToBitmapImageFromPng();
rsb.Items.Add(rb);

public class AdskCommandHandler : ICommand

#region ICommand Members
public bool CanExecute(object parameter)

public event System.EventHandler CanExecuteChanged;
public void Execute(object parameter)
{
string esc = "";
string cmds = (string)Application.GetSystemVariable("CMDNAMES");
if (cmds.Length > 0)
{
int cmdNum = cmds.Split(new char[] { '\'' }).Length;
for (int i = 0; i < cmdNum; i++)
esc += '\x03';
}
string cmdString = parameter.GetType().GetProperty("CommandParameter").GetValue(parameter, null) as string;
if (!String.IsNullOrEmpty(cmdString))
Application.DocumentManager.MdiActiveDocument.SendStringToExecute(esc + cmdString, true, false, true);
}
#endregion

Accepted solution
Here is a complete cs file, using mostly your code, modified so it works without error. Note, you need to change the CopyLocal property of the Autodesk References to False. I also removed the Session flag from the IFC command.
