With the rapid development of social production technology, 3D CAD software has become an indispensable design tool for many enterprises to improve their competitiveness. More and more enterprises are transitioning from using 2D CAD to 3D CAD for business needs. Engineers, mastering a set of 3D CAD design software technology, whether it is postgraduate study or employment promotion is very helpful. So how do you choose the right 3D CAD software as a tool for beginners? As a veteran manufacturer of manufacturing design, the editor wants to mention some immature views and share with you the experience of CAD design for many years.
Maybe a friend will ask, since you have learned to use autocad, do you still need to use 3D CAD? That is because of the traditional design pattern, it is difficult to use 2D drawings to depict three-dimensional space motion and product assembly interference check. There are also many defects: the design is not intuitive, it is easy to produce size or structural interference, and it is difficult to parameterize and variable. Drawing, mismatching with finite element software , CNC manufacturing equipment, etc., as well as computer simulation difficulties, etc., so the workflow is in order. In many cases, products are made, and when the product is assembled, it is found that the interference or the design is unreasonable. These defects greatly restrict the efficiency of product development and lengthen the production cycle.
In the field of manufacturing design, it is urgent to replace the original two-dimensional plane drawing method with an intuitive, parameterized variable design. Compared with 2D CAD, 3D CAD can realistically simulate virtual reality models and express product design results, which is more in line with people's thinking habits and visual habits, so that technicians can get rid of repetitive work, and simple and intuitive graphics change instantly Can be completed. At present, there are many 3D CAD softwares used in China: Catia, SolidWorks, Creo (formerly Pro/e), NX (original UG); domestic 3D, caxa, etc. (and other software that can not be named) ).
Because Catia and NX have very large functions and more than 10,000 commands, it is extremely difficult for beginners to learn. Pro/E learning is also somewhat difficult. It requires strict parameterization during modeling and is not suitable for new product design. SolidWorks is relatively simple in function and relatively easy to learn, but without mold design and CAM processing functions, it needs to be combined with third-party software embedding, such as MasterCAM for CNC machining, which is also a complicated challenge for beginners. On the other hand, due to SolidWorks The surface function is weak. If the product designed by the beginner is more complicated, then SolidWorks is even less suitable for beginners.
In the past 10 years, editors have been using UG and Catia, the first is PORE, these three software is considered high-end 3D CAD software , feels different: UG processing, Catia parametric surface, parametric design, self-top Down-engineering, PROE's parametric modeling is the most practical and powerful of the same type of software . A few days ago, I was asked by a friend company to test the 3D software in China. I was accustomed to using these softwares abroad, and I would not like to learn other software . However, because it is a domestic software , in the support of domestic products, it is tried. For the first time, using Catia's modeling ideas, the results can't be done when sketching. Many functions in the sketch are separate, and many times you need to establish your own reference. The second time you use UG modeling ideas, find out I hope that there are a lot of features in 3D, and the wireframe is also parameterized. In this way, I have done the previous product drawing again. It feels very good. It is very suitable for the Chinese people's thinking habits. The speed is no less than other high-end software , which makes me very surprised.
Checked the information on the Internet, Zhongwang 3D is not really a domestic product, the predecessor is the American CAD/CAM software VX, which was acquired by Zhongwang in 2010. Zhongwang 3D has a unique hybrid modeling technology that can satisfy Class A surfaces and complex surfaces. More importantly, Zhongwang 3D's built-in “learning and learning†learning system makes it easy for users to get started, and the learning is greatly enhanced. It is especially useful for beginners, and it can be used as a design application from a rookie in a short time. These resources are not available from other foreign software . However, Zhongwang 3D is a new force after all. There are still a lot of room for improvement. For example, after changing the parameters, the overall update speed is slow, the CAE function is weak, and the expression function is not perfect.
We are not vetoing foreign software and advocating domestic software . Because it is made in China, I will certainly support it. Of course, Catia, UG and Pro/e, which have been used for so long, will also support the use as always. Good tools are to improve productivity and production. The necessary means of quality. For the development of domestic equipment manufacturing industry, we are obliged to raise our CAD application technology to a higher level.
The editor summed up from years of practical work, no matter which software is a tool, its purpose is to facilitate people's work, study and life. Regardless of how complex the technology becomes, software usability is a constant law. When beginners choose 3D CAD, there is no need to consider which 3D CAD software is powerful. Which 3D CAD software is used in which industry, whether it is foreign or domestic, or need to be based on its own needs, easy to learn and use It is the first choice to meet your own work needs.
Stainless Steel Chainmail Armor is great for display, but also fully wearable for protection. Our various kinds of chainmail armor pieces, such as chainmail coif, hauberk and shirts, is made to look like the originals that you see in museums. Chainmail can give you flexibility and is tougher than ordinary padding or light armor. Knights of the Medieval Era usually wore a chain mail shirt and coif under their armor for better defense from enemy blows.
Today, many people use stainless steel chainmail armor as an interesting display piece in their home. Others still wear some form of chain mail under their armor in the SCA or at the Renaissance Fair. There are also those who make their own by buying loose rings and weaving them together in their own patterns. Whether you're looking for functionality or a unique home accent, Dubetter has what you're looking for!
