1. The magical machine has never been used. I don't understand. It is the earliest software. The update is slow, and the function seems to be very complete.
2. The independent platform Guanglianda does the best in advertising sales, but the software functions are not perfect, many functions are actually lacking, the operation mode is cumbersome, and the flexibility of decorative functions is relatively poor. It is very tiring to count squares when defining special-shaped sections. But the service attitude is the best among several softwares, and there is often training. Prices seem to be different in different regions, especially in developed areas of big cities. The overall feeling is that the cost performance is relatively low.
3. Luban, a software developed on CAD platform, is very quick to use, reasonable in function setting and distribution, and flexible in decorative function, and is very easy to use when dealing with sporadic components (grotesque eaves gutter, parapet, waist line). It also occupies many advantages of the CAD platform itself: stretching, offset, deletion, layer color change and other functions are very convenient to operate. The speed of drawing is very fast. Drawing is mainly based on drawing, and then some modifications are made. Functional perfection and drawing speed are the highest among several softwares, and the adjustment of calculation rules is intuitive, so there is no need to worry about calculation errors. However, after all, it is a platform for pirated CAD, and occasionally there will be some inexplicable BUGG, and the calculation speed is slow. The service is too poor, and the professional level of customer service below is too low, so many problems cannot be solved for customers. At the same time, the management of Luban is very proud and thinks that Lao Tzu is the best in the world. In the forum, if a customer puts forward different opinions, the post will be deleted. Generally speaking, the software is super functional and super fast, but the service is too unprofessional. If you can tolerate the service level that drives you crazy, then the cost performance of this software is quite high.
4. Swire, I haven't used it either. Looks like a CAD platform. It has a very attractive advantage: the integration of steel structure and civil engineering can be completed on one interface, and the speed can be improved a lot. I will have a chance to try one.
