How to hit the castle in China with building blocks?

When building a building block castle, you need to use a software. This software is 3dmax. First, open this software, and then directly pull the corresponding square building blocks and triangular building blocks into the drawing area, so that these building block models can be combined into a whole, thus combining into corresponding shapes. Then you can pull one of the building block models, click Create to select the circle in the figure, so that you can draw a circle in this area, then click Modify directly in the pattern, and then set the corresponding parameters. Then you need to select a square building block model, click Create Geometric Composite Object, and then you need to build a cylindrical model, so that you can copy several copies of the model after pulling.
