The 12 zodiac series of acoustics, which are i-mu, skillfully use bionic design techniques and are loved by many consumers.

Then we will explain the drawing method of its complex surface through one of the shapes. (Physical Reference)

[Analysis Trilogy]]
Point 1: We must analyze the product form before painting, and first understand the basic trend of the form through the side view.

Point 2: Summarize the basic parts through the insertion of key circular proportions.

Point 3: Connect with curves, taking into account the proportional relationship between the outer contour and the internal details.

[detailed steps]]

(1) Draw the central axis of the perspective, and then draw the elliptical section line on the central axis.

(2) On the premise of paying attention to perspective, draw the general outline of the product with a curve and outline it.

(3) Gradually depict the details and draw the details of the product as the body moves.

(4) Add key cross-sectional lines, and deepen the structural lines at the same time to enhance the turning point of the product shape.

(5) Enrich the layout and draw the side view and front view of the product in equal proportion.

(6) Use gray CG4 marker to draw the turning surface of the body first.

(7) Use CG2 gray marker to gradually transition to the brightness part with the product shape trend; Use WG4 warm gray marker to draw the shape of horse leg.

(8) Draw the background with No.47 green marker to enrich the picture.

(9) Enhance the stereoscopic impression of the product by deepening the body turning with a pencil.

(10) Use a highlight pen to highlight the texture of the product at the turning point of the body.
