Delete a model

To delete a model, call the Delete method of the IModel object.

public void DeleteModel(ICommandContext c, ICommandParams p) 
{ 
IModel model = c.App.Workspace.CurrentModel; 

//Delete the model 
model.Delete(); 
} 

If the child element is owned, you can also delete it using the RemoveField method of the IModel object as follows. If it is a reference, simply delete the reference.

public void RemoveField(ICommandContext c, ICommandParams p) 
{ 
//Create a model in the project 
var ucModel = c.App.Workspace.CurrentProject.AddNewRootModel("UseCaseModel"); 

//Create a use case 
IModel uc = ucModel.AddNewModel("UseCases", "UseCase"); 

//Add a scenario to the use case 
IModel scenario = uc.AddNewModel("Scenarios", "Scenario"); 
c.App.Output.WriteLine("sample", $"Scenario: {scenario.Name}"); 

//Delete a scenario 
uc.RemoveField("Scenarios", scenario); 
c.App.Output.WriteLine("sample", $"Scenario IsDeleted: {scenario.IsDeleted}"); 
} 

Note

When you use the IModel.RemoveField method on a reference field, it only deletes the reference relationship, not the related model.
