In the world of CAD, engineers often face challenges when dealing with complex designs or specialized tasks. While the built-in features of standard CAD software may not always suffice, leveraging the API functions of CAD platforms can significantly enhance productivity and meet specific business requirements. This is where customization and secondary development come into play, allowing users to tailor the software to their unique needs.
Among various CAD solutions, Zhongwang CAD+ stands out as a powerful platform that offers efficient and convenient custom development options for enterprises. The software provides a rich set of tools for developers, including LISP, VBA, ZRX, and .NET. Among these, LISP and VBA are relatively easier to use but offer limited functionality compared to ZRX. ZRX, which is based on the VC++ platform and uses C++, allows for advanced object-oriented programming, making it highly powerful. However, it requires more expertise and has a slower development cycle.
Zhongwang CAD+ has made significant improvements in its LISP support, offering over 95% of AutoCAD's functionalities. It now supports a wider range of reactors and permanent reactors, along with enhanced engineering configuration and interaction capabilities with ZRX. Additionally, performance has seen a substantial boost. For example, a simple loop test shows improved execution speed:
```lisp
(defun test ()
(setq a 1 b 1 c 1 i 0)
(while (< i 1000000)
(setq a (+ a 1) b (+ b 1) c (+ c 1) i (+ i 1))
)
)
(defun gt () (* 86400 (getvar "tdusrtimer")))
(defun tt ()
(setq t1 (gt))
(test)
(princ " time:")
(princ (- (gt) t1))
)
(tt)
```
The results demonstrate that Zhongwang CAD+ performs much faster than its previous versions and is comparable to AutoCAD in terms of computational efficiency.
VBA in Zhongwang CAD+ has also seen improvements, making it more user-friendly and stable. When it comes to ZRX-based applications, compatibility is one of the key advantages. Many ARX functions can be easily transplanted, sometimes even more efficiently than with VBA. Zhongwang has developed several large-scale professional applications, such as mechanical and architectural versions, and successfully ported plugins like CASS and Lizheng from AutoCAD.
Starting from the 2014 version, Zhongwang CAD+ introduced support for .NET, enabling developers to use languages like VB.NET, C#, and Managed C++. .NET combines the power of C++ with the ease of use found in VBA or LISP, making it an ideal choice for developing robust and scalable applications. Its garbage collection mechanism helps prevent memory leaks, and the framework offers better encapsulation of classes and controls for building user-friendly interfaces.
In summary, the secondary development capabilities of CAD software play a crucial role in expanding its functionality to meet diverse user needs. Zhongwang CAD+ provides a mature and flexible API, allowing users to either migrate existing programs or develop new ones directly on the platform. The result is a more efficient and tailored design experience.

Ceiling Roses/Ceiling Medallions
PU Ceiling Roses decorative element breaks up large ceiling surfaces and light up your room.you may paint it to combine your funiture color, this series goods give you complete new decorative room!Except the this,we also have Ceiling Rings.
