Packing boxes and more widely, to improve the efficiency of the tray structure design , is to increase the interests of the manufacturers of the packaging carton . Structure CAD system in view of the foreign carton sold at higher prices , domestic narrow range corresponding software status quo structure CAD system with the carton at home and abroad , the topics proposed a new method of packaging cartons structure parametric design AutoCAD 2002 based on ObjectARX technology , specifically for this issue of how to facilitate the design of the packaging tray structure for secondary development , developed convenient carton packaging structure design CAD ??system . The topics rectangular hexahedral packaging tray , for example , the use of AutoCAD open architecture , COM, process , MFC, ObjectARX technology to develop the packaging carton structure CAD system . The tray structure design details , such as the indentation line , so the the knife bit key concepts are integrated into the system , which simplifies the design process , saving design time , reduce the labor intensity of designers . In addition, the packaging carton structure CAD system functional requirements , the friendliness of the system interface development and design, to make the system more harmonious and friendly . Topics in the DXF file format for packaging cartons structure to expand the final file storage format in AutoCAD is very easy to implement , this document storage format for subsequent processing ( laser cutting die machine platemaking ) easy .
