CAD Information Embedding and Retrieving based on ActiveX Automation
Based on the study of the Intelligent recognition and processing of CAD graphs for the quantity estimation in civil engineering, taking advantage of the database of CAD graphs to build graphic database, the authors bring forward a unique technique for the embedding and retrieving of quantity information to make CAD intelligent recognition possible. Meanwhile, together with ActiveX automation, algorithms are given to implement the information embedding and retrieving, and export to Windows application as well. It is applicable to engineering design to optimize engineering applications and improve its efficiency.
