CAD It is an automatic computer-aided design software, which can be used to draw two-dimensional drawings and basic three-dimensional designs. You can draw it automatically without knowing how to program it. Therefore, it is widely used in civil engineering construction, decoration, industrial drawing, engineering drawing, electronic industry, clothing processing and other fields. In order to help more friends learn CAD quickly, there are many video tutorials about basic introduction, intermediate advanced and advanced development of CAD. If you study CAD, you must have a look.

Three basic skills of CAD drawing

First: learn to look at pictures.

If you want to draw a picture, you must look at it first. It is almost impossible for beginners to draw directly as soon as they get started. First of all, we must learn to read drawings and understand what a drawing expresses.

Only on the basis of understanding the drawings can we enter the next step, drawing stage. The most important thing is to understand the "label", "layer" and "scale size" of the whole drawing, and to have a "global view" Beginners should focus on the above three points when looking at pictures. When we are familiar with the standards of design drawings, we can start drawing.

Second: drawing standards

Create layers, including name, line width and line type; Secondly, determine the drawing scheme, and follow the principle of "center first, then part" in the drawing process. First, determine the center line of the drawing, then slowly draw the local edge, and finally finish the whole drawing by trimming.

Dimensions: It is very important to determine the scale of our drawings through conversion. Proportion is one of the cores of a painting. If the scale is wrong, it can be said that the whole picture is wrong. Novices must be careful here. After the calculation is completed, the drawing will be marked.

Third: check for errors.

For beginners, there are often many mistakes in the drawing. Therefore, we must form the habit of regular inspection, find out the shortcomings and problems of our own drawings through constant comparison, and constantly correct them. In this process, we also exercised and tested our abilities.

CAD drawing is not something that can be completed overnight. Need long-term persistence and practice. If you are a beginner in CAD drawing, I suggest you take a training course in CAD drawing, which will definitely be much faster than self-study.

This is the "three basic skills of CAD drawing". I hope this tutorial can help you. You should follow the tutorial, so that you can get started faster. Click this link to learn more about CAD tutorials:
