Why did Tianzheng Construction expire? ——Analysis of software updates and industry trends
In recent years, the digital transformation of the architectural design industry has accelerated. Tianzheng Architecture, as the mainstream CAD-aided design software in China, has attracted much attention on its version updates and authorization issues. This article will combine the hot topics on the Internet in the past 10 days to analyze the reasons for the "expiration" phenomenon of Tianzheng buildings, and attach structured data for readers' reference.
1. Three core reasons why Tianzheng buildings expire

1.Software version iteration cycle: According to Tianzheng’s official announcement, maintenance services for versions below T20 V7.0 will be stopped starting in 2023, causing some users to be prompted with “expiration” because they did not upgrade in time.
| version number | Stop maintenance time | alternative version |
|---|---|---|
| T20 V5.0 | January 2023 | T20 V8.0 |
| T20 V6.0 | June 2023 | T20 V9.0 |
2.Copyright protection strengthened: In 2024, the country will promote a special campaign to legalize software. Tianzheng will launch a new encryption system. Unauthorized versions will trigger an expiration prompt.
3.Technical architecture upgrade: The popularization of BIM technology has prompted the reconstruction of the underlying software, and old versions are incompatible with new platforms such as Revit 2024.
2. Industry hotspot correlation analysis
The popularity data of the entire network in the past 10 days shows that the architectural design field is most concerned about the following topics related to technological updates:
| Hot search keywords | search volume index | Related platforms |
|---|---|---|
| Tianzheng Construction authorization failed | 285,000 | Zhihu/CSDN |
| BIM mandatory certification | 192,000 | WeChat public account |
| CAD cloud collaboration | 157,000 | Station B/Douyin |
3. User response plan
1.Genuine migration plan: Tianzheng provides tiered discounts for old users, and you can enjoy up to 60% discount for bulk authorization.
2.technology alternatives: Some small and medium-sized enterprises have begun to try domestic alternative software. The following is a comparison of mainstream alternatives:
| Software name | Compatibility | Annual fee (yuan) |
|---|---|---|
| Haochen CAD Architecture Edition | Support Tianzheng drawings | 4800 |
| Glodon BIM | Need to convert format | 9800 |
4. Forecast of future trends
According to the requirements of the Ministry of Housing and Urban-Rural Development’s “White Paper on Digital Transformation of the Construction Industry”, all Grade A design institutes must complete the full-process application of BIM by 2025. This means that the life cycle of traditional CAD plug-ins will be further shortened, and the software update frequency may be shortened from the current 18-month cycle to 12 months.
It is recommended that users createRegular upgrade budget, incorporating software expenditures into project cost accounting. At the same time, pay attention to the two major version update notices officially released by Tianzheng (in March and September every year) to avoid affecting the project progress due to technological obsolescence.
