Design Pattern For Creating Objects and Child Objects

Question

I wonder if there is any kind of design pattern that make my code more concrete.

I guess a Factory Method Pattern can help me but not sure.

Below the code, the Shape creation Method needs other creation methods to create child elements (ex: Extrusion -> Loop -> Vertices). Inside Shape creation method, a programmer should customize created child element to clarify what shape the method will make. Below is just a my situation don't have to get deep into my situation. Anyone can help me, any suggestions will be glad.

thank you.

here is my suedo code flow written in C#. Sorry for the lack of details but better to understand faster.

public class SomethingClass
    {

        //Some codes...

        //create Circle
        public void CreateCircle(string SomethingPathName)
        {
            var element = CreateExtrusion(SomethingPathName);

            //some codes goes like below
            element.foofoo = bar;

            element = CreateLoop(element);

            foreach (var foo in bar)
            {
                element = CreateVertices(element);
            }
        }

        //create Rectangle
        public void CreateRectangle(string SomethingPathName)
        {
            var element = CreateExtrusion(SomethingPathName);

            //some codes..

            element = CreateLoop(element);

            //some codes..

            foreach (var foo in bar)
            {
                element = CreateVertices(element);
            }
        }

        //create something other shape
        public void CreatePyramid(string SomethingPathName)
        {
            var element = CreateExtrusion(SomethingPathName);

            //some codes..

            element = CreateLoop(element);

            //some codes..

            foreach (var foo in bar)
            {
                element = CreateVertices(element);
            }
        }

        // so one...

        //Some codes...
    }

below is my more specific real codes. I dont want you to get pain from this but if might be needed.

Answer 1

In your case, factory or abstract factory pattern.

There are the below design pattern for creation of object.

1. Factory Method Pattern
2. Abstract Factory Pattern
3. Singleton Pattern
4. Prototype Pattern
5. Builder Pattern
