Add a model

This explains how to add a child model to a model field.

Add a model to a field

To add a model to a specific field of a model, use the AddNewModel method of the IModel object. The addition destination is the end.

public void AddNewModel(ICommandContext c, ICommandParams p) 
{ 
IModel model = c.App.Workspace.CurrentModel; 
//Add a model of the "SoftwareComponent" metaclass to the "Components" field 
model.AddNewModel("Components", "SoftwareComponent"); 
} 

Add a model to a specified position

To add a model to a specific field and specific position of a model, use the AddNewModelAt method or AddNewModelTo method of the IModel object. The addition destination is the end. The following is an example of adding a model before the model named "Function Requirements" in the child element model of "Lane Keep Assist Function Requirements".

public void AddNewModelTo(ICommandContext c, ICommandParams p) 
{ 
IModel model = c.App.Workspace.CurrentProject.GetAllChildren().FirstOrDefault(m => m.Name == "Lane Keep Assist Function Requirement"); 
var targetModel = model.GetAllChildren().FirstOrDefault(m => m.Name == "Functional Requirement"); 
string fieldName = "SubRequirements"; 
string className = "SystemFunctionalRequirement"; 

var addModel = model.AddNewModelTo(fieldName, className, "before", targetModel); 
c.App.Output.WriteLine("sample", $"{addModel.Name} has been added to field: {fieldName} of model: {model.Name}."); 
}
