IModel.AddNewModelAt method
Namespace: NextDesign.Core
Description
Adds an instance of the specified class at the specified add position as a field value to the specified field of this instance.
Allows instantiation even if the specified class is an abstract class, and adds it as a field value at the specified position.
The specified field must be an owning field of the class type.
Note that no exception is thrown even if the upper multiplicity constraint of a field with a multiplicity of 2 or greater is violated.
The class name you specify must specify a type that is compatible with the data type of the field.
Also, when doing a fuzzy match, if there are multiple matching classes, add the instance of the first type-compatible class found.
