How do rhinoceros shape polygonal speakers? Rhino modeling method of polygonal loudspeaker

Rhino is a good 3D modeling tool. Although it is only tens of megabytes in size, it does not require much hardware. But it contains all the NURBS modeling functions, which is the main reason why rhino is popular. Everyone likes to use it to make high-precision models for other 3D software. If you are also engaged in 3D design, you must learn to use Rhino software. Rhino not only has low requirements for computers, but also is very simple to use. You can learn to use it through self-study. The Basic Course of Rhino Industrial Design and Modeling is a very good self-study course, and many self-study rhinoceros friends are watching it.

Rhino modeling method of polygonal loudspeaker

0 1. Analysis model: first analyze the model, ignoring all the details, the product is a cuboid, then cut and shaped on the basis of the basic body, and finally go deep into the details.

02. Put the background picture into rhino in the form of drag and drop, and lock it for reference.

03. Draw a rectangle with the proportion of the small speaker in the top view, and stretch the body according to the height of the speaker.

04. Draw a ball centered on the vertex of the cuboid at the corner cutting position.

05. Find the intersection of a sphere and a cube (this is to ensure that the tangent angles of each side of a triangle are the same length).

06. Connect intersection points

07. Divide the cuboid with connected triangle lines.

08. Hide all lines and use closed curves and surfaces to make triangular surfaces.

09. According to the modeling, offset the top curve inward.

10. Trim the excess parts.

1 1. All curves are rounded.

12. Stretch the body and perform Boolean segmentation with the subject.

13. According to the shape of the speaker, the divided body is slightly lowered to create a height difference.

14. Lock the outer body, which is convenient for us to model, copy the edge line of the inner body, and offset it inward by 2 segments according to the modeling.

15. Split the top surface, lower the center surface, and delete the middle split surface.

16. Intermediate surfaces use blending commands to regenerate surfaces.

17. Draw the top grid modeling circle.

18. Use linear array to arrange a row horizontally and group them.

19. Then arrange the groups vertically.

20. Ungroup, delete the redundant parts and stretch the adult.

2 1. Do Boolean product operation with the main body and cut out the grid.

22. Offset the small oblique side line inward.

23. Stretch the adult and perform Boolean segmentation with the subject.

24. Cut out triangles and chamfer the edges.

25. Spread the triangular surface only by uv.

26. Find the center point of the triangle, draw the runway circle, and divide the circular array into three parts with this point as the center.

27. Offset the triangle inward and trim the shape.

28. Draw the modeling process to a triangle.

29. Stretch the geometry, perform Boolean division and chamfer.

30. Draw the circle of the button, stretch it into an adult, carry out Boolean segmentation with the main body, and cut out the button.

3 1. Draw a pattern on the key, stretch the object, and perform Boolean product operation with the key.

32. Chamfer all edges according to the shape.

33. Switch to rendering mode, open the pop-up material and give it the corresponding material.

34. The overall modeling is completed
