What is the difference between 3D, 3D and CAD?

3D is the abbreviation of three-dimensional, which refers to the three-dimensional graphics displayed on the computer plane. Although real three-dimensional space and distance cannot be represented in a computer, images can be made to look more realistic through techniques such as perspective and shadow. Computer-generated 3D graphics can provide more three-dimensional and vivid visual effects and are often used in games, animation, virtual reality and other fields.

Three-dimensional is obtained by combining a two-dimensional and a one-dimensional, and it is three-dimensional. However, what we call front and back, left and right, and up and down in common sayings are only relative to the point of view of observation, and there is no absolute front and back, left and right, and up and down.

CAD is the abbreviation of computer-aided design, which helps designers carry out design work with the assistance of computers and graphics equipment. In engineering and product design, CAD can help designers complete calculations, information storage, and drawing. It uses the computer's powerful computing power and graphics processing capabilities to provide an efficient and accurate design method. Designers can use CAD software for modeling, drawing, editing and analysis to quickly complete design tasks and improve work efficiency and design quality. CAD technology has been widely used in various fields and has become an indispensable tool in modern design work.

A popular saying at present is that 3D design usually refers to 3D animation, also known as animation design.

CAD design is a major focusing on design, including two-dimensional graphic design and three-dimensional design. It is a targeted design method that aims to use computer-aided tools to create and edit various design solutions. In 2D graphic design, designers can use CAD software to create floor plans, drawings, layouts, etc. In three-dimensional design, designers can use CAD software to model, render and display realistic three-dimensional objects.

Three-dimensional design is just a general term, it can also be 3D or CAD

CAD 3D drawing and 3DMAX

There are actually some differences between these two softwares. CAD is a software based on NURBS modeling, mainly used for engineering design and product design. 3DMAX is a software based on polygonal modeling, mainly used in fields such as film and television special effects, game production and animation. Although the two have different uses, they can also be used complementary to each other in certain situations. Hopefully this explanation helps you better understand the differences between them.

Although 3DMAX can be combined with CAD, it is limited to importing CAD architectural plans and cannot involve the 3D part of CAD.

The first thing to make clear is that CAD is a production-oriented software, mainly used to draw mechanical and product structure drawings. 3DMAX is a three-dimensional animation software. Although CAD is commonly used in the construction industry to draw house plans, CAD is actually used to design mechanical parts and product structures. It is similar to how many people use PS for drawing. However, PS itself is not specifically used for drawing, but for drawing. for image processing. Similarly, CAD itself is not specifically used for architectural design, but is a tool for designing mechanical parts and product structures.

CAD software is used to model entities and can directly manufacture models into physical objects, while 3DMAX software is mainly used to create renderings and animations. 3DMAX is based on the polygon (POLY) modeling method, which is suitable for producing highly detailed scenes and characters, such as movie special effects. CAD software, on the other hand, is based on solid modeling and is more suitable for producing objects such as engineering models and mechanical parts that require precise dimensions and structures. Both have their own advantages and uses in different fields.

To put it simply, for example, use 3DMAX to make a cube. In fact, the cube is a hollow box... If you delete a face, it will be empty inside... And those faces actually have no thickness... .In the real world, things without thickness do not exist. Therefore, the 3DMAX model can only be used for "seeing" and cannot be manufactured...And a cube built in CAD is actually a solid tiles...This model can be processed and produced....

There is actually no need to learn the three-dimensional part of CAD...because the design department in the factory does not use CAD when doing modeling...but uses SOLIDWORKS, PRO/E, UG, and CATIA. Such software... These software are also 3D software... They are used for product design... The models created can be produced by the workshop Processed into products, and can be programmed with CNC... So even if you learn the three-dimensional part of CAD, it has no meaning... because CAD is not used at all in the design process of the factory. Modeling is not used in any other industry...

In fact, you first need to figure out what industry you are in...

If you are engaged in industries that deal with factories, such as product design, mechanical design, metallurgy, casting, etc., learning 3DMAX is not necessary. Instead, you need to learn some other software, such as SOLIDWORKS, PRO/E, CATIA, etc. These software are called essential tools for product engineers. These software can help you with product design, mechanical design and other work. So, if you want to succeed in these fields, it is recommended that you learn these software.

If you want to engage in architectural structure design, it is very important to learn PKPM and REVIT, because these are essential tools for construction engineers. PKPM is a structural analysis and design software that can help you calculate and optimize structures. REVIT is a building information modeling software that can help you design and visualize building models. Mastering these two software will lay a solid foundation for your construction engineering career.

If you are engaged in indoor and outdoor decoration and architectural appearance design, it is necessary to learn 3DMAX. 3DMAX can help you create realistic renderings, making your designs more vivid and concrete. It is a very powerful tool that provides various rendering and modeling functions to make your designs more professional and sophisticated. Whether it is displayed to customers or used for publicity and promotion, 3DMAX can help you

If you want to enter the film and television special effects industry, you should learn CINEMA 4D and AE, which are essential skills for film and television post-production and special effects artists.

If you are engaged in game production, you should learn MAYA and UNITY3D, which are essential tools for game designers. MAYA is a powerful 3D modeling and animation software that can be used to create characters and scenes in games. UNITY3D is a popular game engine that can be used to build game logic and interactions. Mastering these two tools can help you become an excellent game designer.

How do I import 3D drawings into CAD

method one:

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. First, you need to select your line segments.

What is the relationship between CAD and 3D

CAD is mostly used for plane planning and design of drawings, and also has the function of 3D modeling (but few people use it in the field of interior design). The drawings that cad needs to produce in the field of interior decoration include original floor plans, floor layout drawings, Ceiling layout drawings, furniture size drawings, strong and weak current drawings, socket layout drawings, elevations, sections, etc., are mostly flat drawings. You can refer to what others have done online and learn from it.

3D design is mainly based on renderings. The software used is mostly 3DS MAX 8.0 or higher, and the vray -1.50R3 plug-in needs to be installed to obtain better rendering effects. 3ds is mainly used for modeling to help designers create models.

If you want to learn 3D modeling, I suggest you buy a book that matches the version of the software you have installed. Such books usually provide a detailed analysis of one or two sets of model modeling. You can practice multiple times according to the tutorials in the book, and you will be able to master the basic skills after about 3 to 5 times. In addition, you can also look for some tutorials on lighting and cameras online so that you can progress faster.

I wish you explore more, learn more knowledge and get more happiness in the field of decoration!
