Using this function in 3dsmax, cones, piers, pyramids and piers can be built quickly, which is convenient for the design of ordinary 3D model foundation. Use the mouse to create a standard cone model. A) start 3dsmax software. B) Click the Cone button in the Create command panel on the left side of the view, and we will temporarily create a cone with default parameters. Please look at the chart 1. C) Move the mouse to any window on the left side of the creation panel, click the left mouse button, then press and drag the mouse diagonally, and a circle will appear in the window, as shown in Figure 2. D) Release the left mouse button, and then move the mouse up. At this time, you can see that the height of the cone begins to increase and a cylinder appears in the window. See figure 3. E) Click the left mouse button, and then move the mouse to the lower right corner. At this time, you can see that the top of the cylinder begins to shrink (it will enlarge in the opposite direction). When the top shrinks to a point, click the left mouse button again to complete the creation of the cone shape. Click the right mouse button to end the creation. See figure 4. Create a standard cone model using the keyboard and parameters. F) reset 3dsmax software. G) Click the Cone button in the Create command panel on the left side of the view. H) Click the keyboard entry at the bottom of the creation panel with the mouse, and we can see the following parameters, where the above x, y and z refer to the three-dimensional coordinates of the cone to be created, the radius 1 (radius 1) corresponds to its bottom radius, and the radius 2 (radius 2) corresponds to its top radius and height. I) Keep the values of x, y and z as "0", that is, the origin of three dimensions, the value of radius 1 is 50, radius 2 is 0 and height is 100, and then click the Create button. After creation, we can continue to modify the parameters of the cone shape as needed. After creation, you can also adjust its parameters in the Modify command panel. Let's continue to look at what other rollouts do: names and colors. The main function of this rollout is to name the cone you created and mark the cylinder color. The default name is Cone0 1, and the color is generated randomly. The creation method rollout is divided into two modes. The edge option is created with the tangent of the circle, and the center option is created with the center of the circle. By default, it is central mode. The parameters are the same as those in the modify panel. It is mainly edited again after the cone is created: radius 1 (radius 1), radius 2 (radius 2), and the height corresponds to the bottom, top and height of the cone just created. Height Segs, Segs cap and number of edges are three parameter options for cone refinement, and the default number of edges parameter is 24. Smoothing: By default, this option is selected to smooth the surface; When unchecked, map coordinates with angle effect will be generated; This function is to automatically load the mapping coordinates attached to the program after creating the cone, without repositioning the mapping coordinates again; By default, it is selected. Real world map size: This function is a global setting, and users can manually select the style of texture coordinates used. When enabled, the real coordinates are used for the sample window display, and the default state is off.
