Show revision list

To display the revision list dialog for a configuration-managed model file, call the ShowRevisions method of the ICommonUI object.

public void ShowRevisions(ICommandContext c, ICommandParams p) 
{ 
var model = c.App.Workspace.CurrentModel; 
var modelUnit = model.ModelUnit; 

ICommonUI commonUi = c.App.Window.UI; 

switch (modelUnit.Type) 
{ 
case "Project": 
//If the unit type is project, call the method without specifying the model unit. 
commonUi.ShowRevisions(); 
break; 
case "Model": 
//If the unit type is model, call the method with the model unit specified. 
commonUi.ShowRevisions(modelUnit); 
break; 
} 
} 

tip

In the displayed revision list dialog, select a revision and press the "Compare with this revision" button to start comparing with the selected revision.
