2026 CAD Drawing AI Intelligent Recognition: How to Achieve Automatic Legend Statistics and Integrated Parameter Control?

In 2026, intelligent recognition of CAD drawings relies on native vector parsing and visual AI large models to achieve automatic legend extraction and statistics, with accuracy as high as 95% or above, and one-click generation of structured lists. Implementation is divided into four steps: multi-format drawing access and semantic parsing, intelligent recognition of legend symbols, global unified setting of layer attribute parameters, and intelligent verification and version difference comparison. The system can convert drawings into structured data such as JSON/Excel, connecting the links from design to cost estimation and construction.
