What is building modeling? What materials should be used?

Modeling is to build a model. Simply put, draw the shape of the house in the computer, which can be two-dimensional or three-dimensional. There are many professional drawing softwares.

A, modeling software:

1.autocad, which is a common software in the industry. Because it is universal, there is no module specially suitable for architecture. You can use basic commands to model, but it takes a long time. Disadvantages of software: poor editing ability, weak surface function and extremely consuming system resources. There are many CAD plug-ins on the market. The most classic plug-in is Tianzheng-for architecture and explorer-for structure. These plug-ins can be found at Baidu for free.

2.autodesk revit architecture is a 3D modeling software specially developed for architecture, which can quickly model and modify 2D and 3D drawings simultaneously.

3.sketchup is very suitable for rapid modeling in the scheme stage, which is convenient, but if you want to do complex design or make construction drawings, forget it.

4. rhinoceros rhinoceros. The operation habit is exactly the same as autocad, but it can build more complex models than cad, especially surfaces, and the modeling speed and display speed are several orders of magnitude faster than CAD. The lower version of rhinoceros has external parameterized plug-ins, and the higher version of rhinoceros has built-in plug-ins.

5.CATIA is a top-level 3D modeling software, which can be used for parametric design, nonparametric design and mixed modeling. Widely used in aviation field, but also in high-end architectural design field, especially when encountering complex buildings such as curved surfaces and special shapes. In addition to modeling, it also integrates CAE, CAM and other functions, far exceeding CAD.

Need to explain two points:

1.3DsMAX and MAYA are powerful in three dimensions, but they cannot accurately model and generate two-dimensional construction drawings that meet the design requirements. Therefore, these two softwares can not be used in engineering design industry, but can only be used for video modeling, animation and special effects.

2. The above five 3D softwares can render and define materials, but they are all amateurs. These renderings can't be used for professional design, and it's ok for amateurs to look fun.

Second, the rendering and animation software:

If a 3D model needs to be rendered or animated, it can be imported into 3DsMAX or MAYA. The former is suitable for architectural themes, while the latter can directly produce Hollywood blockbusters with light and shadow effects, and participated in the production of Avatar.

Third, adobe photoshop.

Image post-processing software is irreplaceable. Although rendering software can help you calculate the real effects, post-processing can make these effects more brilliant. Some exquisite works can't do without this process, which is equivalent to the starch you put in the dish when it is finally out of the pot.
