Automatic 3D CAD Model and 2D Drawings Generation in Construction Engineering

Abstract

Automatic CAD design is difficult in construction field, since the construction environments vary case by case. Although the steps are similar, each creation is very time-consuming. Therefore, in this research a method that could automatically generate 3D CAD models and 2D drawings from the onsite measured geomorphological features is proposed to solve the complicated and similar process. This proposed method was implemented through the API (Application Programmable Interface) of CAD system and has been verified in practice that labor costs and time costs have been greatly reduced. In addition, mixed reality is applied to verify the assembly results, and an effective and realistic experience is provided to the user and the customer.
