The invention provides an Internet aided design (iAD), and aims to provide an auxiliary
design tool for indoor designers and design fans. The iAD adopts an MVC (
Model View Controller) architecture, and is realized by the interactive embedding development of App (Application) and Unity and uses a function manager to uniformly manage function modules, wherein the function modules comprise a decoration design module, a decoration budget module, a construction drawing design module, a
client management module and an iAD
service module; the decoration design module provides two
modes of on-line decoration and off-line decoration; and the construction drawing design module is used for designers to realize wall surface, ground and top surface design, vertical face design,
layout design, waterway design,
circuit design and construction technology design. The iAD provides a full-course auxiliary means for the quick design, the effect representation, the sharing and the communication of indoor decoration, and constructs a zero-distance interaction space between the designers and users.
