Design And Implementation Of Mobile Terminal Mechanical Caddrawing View System

Mobile devices play an important role in people's work and life with the increasing performance of mobile terminal equipment, in which CAD can play an increasingly large role. In the present study, the mobile mechanical CAD drawing view system is designed and developed combined with CAD drawing exchange file DXF format based on the Android. Cloud drawings can be downloaded by staffs related with CAD through the mobile Internet to view and modify the drawings whenever and wherever, breaking the shackles of time and space. The system also provides the query of international standard parts, concluding accurate information about them. Viewing CAD drawings through mobile terminal not only improves efficiency but also reduces work burden greatly.The thesis completed the following work:(1) DXF file can be written through the analysis of CAD drawing exchange file. Then the information obtained is stored in the establishment of date storage structure to complete the drawing. Therefore, the amplification, reduction and move of drawing, as well as add and delete notes are completed.(2) The drawings can be uploaded and downloaded by the mobile Internet with the help of the cloud disk.(3) According to the name of standard mold, the international standard graphics and dimension are figure out.The classification information of the materials for the stamping dies is provided.The system was tested on the nuts cell phone and Android simulator to debug of the system. To confirm the CAD drawing view system for mobile terminal mechanical can operate normally on the Android mobile devices and complete the above functions.
