The standard line is lighter at both ends and heavier in the middle; When arranging parallel cables, you can arrange parallel cables in turn from a convenient direction. When practicing, you must have a smooth wrist and even force, and the relationship between the density of lines should be properly grasped. The density of lines directly affects the relationship between light and shade.
2. Cross cable layout
The direction of the second pass line and the first pass line is preferably rhombic when crossing the line arrangement; Cross cable arrangement is the most commonly used method, especially when drawing gray and black surfaces. Layers need to be superimposed, so that the picture will not appear "greasy".
3. Overlapping cables
Overlapping cable arrangement is to arrange cables repeatedly in one direction, overlapping into a color block, and the lines are almost invisible. This painting method is also often used to represent the dark parts of objects.
4. Arc spectral line
Round, curved objects, muscle trends, textured objects, etc. Use arcs more, because arcs have a certain radian, which is more free and casual than straight lines and will have a better texture effect.
The pen holding posture is as follows:
Hold the pen: This method is the usual writing posture, as shown in the figure below. This pen-holding method can be used on the dark side with a small area, or it can be widely used in monomer molding. Unlike the stick-holding method, it is easy to master in a large area, and just wants to draw lines like writing.

Practice linear sketch:
Before studying, you need to know what the core of sketch is. Of course, the core of sketch is modeling. When we paint, we should always take solving the modeling as the main goal. No matter what kind of line is used to express the work, the line should be placed on the form, and every stroke should be followed. We don't need to think too much about the light and shadow effects of objects, but should focus on objective objects.
Maybe many candidates still don't understand, they always use lines, and there is no light and shadow effect. What about space? First of all, we should understand several key words: rhythm, visual center, structure and perspective.
When grasping the space of linear sketch, we can't do without these words. The most basic job performance, one is to have an accurate perspective relationship, and the other is to have a relationship between black, white and gray (the relationship between black, white and gray is somewhat similar to the relationship between reality and reality). Secondly, when painting, we must find the visual center of the picture, use rich pens, and weaken the rest of the picture in turn, so that the picture will have a strong sense of rhythm and natural space.
In fact, when painting, we should also consider the influence of line changes on space. Many candidates have a misunderstanding that when painting human bones, the prominent parts of human bones must be painted very heavily, which is a one-sided understanding.
Because accidental factors such as the influence of light should be properly considered, when the human skeleton is convex, the convex place is bright, and the concave place is key and black; The place where the lines cross is heavy and dark.
In short, in sketch training, we should observe and feel more objects, firmly grasp the core content of sketch, develop good observation methods and painting habits, and produce a correct consciousness of our own through continuous painting practice.
