When the 2D design is completed, the 3D result can be output directly, without increasing the additional workload of users, and the results are expressed intuitively.

The mainstream design platform remains unchanged and the platform learning cost is omitted; 2D design can be modelled, to shorten the learning time of modelling process.

The planning module covers index decomposition, pipe network calibration and waterlogging simulation; the design module covers the design of residential areas, plant areas, roads and parks, etc., and generates word-specific reports with one click; the review module can directly output evaluation reports.
