[Closed] Creating Instances of Max classes in C#

There are many cases where you need to create instances of Max classes – classes that are defined in the Autodesk.Max DLLs.

It’s not always obvious how to create these objects, so I put together a factory for building them. I wanted to share it, in case it’s useful for anyone else.

Note: ‘Global’ below is shorthand for GlobalInterface.Instance

    public static class ObjectFactory
    {
        public static IClass_ID CreateClassID(uint firstId, uint secondId)
        {
            return Global.Class_ID.Create(firstId, secondId);
        }

        public static IFPValue CreateFPValue()
        {
            return Global.FPValue.Create();
        }

        public static IPath CreatePath(IPath existingPath)
        {
            return Global.MaxSDK.Util.Path.Create(existingPath);
        }

        public static IPath CreatePath(string path)
        {
            return Global.MaxSDK.Util.Path.Create(path);
        }

        public static IBitmapInfo CreateBitmapInfo()
        {
            return Global.BitmapInfo.Create();
        }

        public static IBitmap CreateBitmap(IBitmapInfo info)
        {
            return Global.CreateBitmapFromBitmapInfo(info);
        }

        public static IBox3 CreateBox3()
        {
            return Global.Box3.Create();
        }

        public static IPoint3 CreatePoint3()
        {
            return Global.Point3.Create();
        }

        public static IMatrix3 CreateMatrix3()
        {
            return Global.Matrix3.Create(true);
        }

        public static IMesh CreateMesh()
        {
            return Global.Mesh.Create();
        }

        public static ITab<T> CreateITab<T>()
        {
            return Global.Tab.Create<T>();
        }

        public static IMatrix3 CreateMatrix3(IMatrix3 matrix3)
        {
            return Global.Matrix3.Create(true).MultiplyBy(matrix3);
        }

        public static IInterval CreateInterval()
        {
            return Global.Interval.Create();
        }
    }
