The function of CAD mainly lies in drawing accurately. One is plane reference, because in many landscape renderings, it is impossible to draw accurate terrain with 3D, and the general practice is to import the drawings drawn by CAD into 3DMAX as a reference; The second is to draw complex graphics. In the process of making renderings, it is difficult to complete complex or accurate graphics in 3D, and CAD is needed to assist. The third is the use of some model bases. What does cad mean? A large number of professional application modules and software of CAD determine that it is fast and convenient in a certain field and aspect, and it is wrong not to treat it objectively.
In addition, it is difficult for workers to construct according to the renderings, because the renderings only do the visible parts and the invisible parts are not done; The drawn model can't measure its exact size. Therefore, many customers will request to draw a construction drawing at the same time, including plan, elevation, section, ceiling, circuit diagram, lighting bitmap, partial details and so on. This requires us to have a strong ability to read pictures. If you can't understand the basic plan, elevation and section, you can't make accurate renderings according to the drawings, let alone draw construction drawings according to the completed renderings.
