应用需求: 随着有线电视行业的迅速发展,其用户数量及业务规模都在不断的扩大。而对行业生存的根本:“网络资源”的管理是有线电视台(公司)所面对的一个重要课题。而相关的工作则是网络工程设计人员所面对的大量图纸的设计和管理。图纸设计从最初的完全手工逐步发展到计算机辅助设计,设计人员的劳动强度在不断减小,而工作的质量却在明显提高。计算机设计软件的使用几乎已经是有线工程设计人员所必须掌握的基本技能。目前许多图纸设计人员使用了AutoCad作为设计网络图纸的工具,而AutoCad强大的绘图功能也足以解决设计中所要求的各种问题。但大多数设计人员同时面对的问题就是熟练掌握使用AutoCad及在AutoCad上进行二次开发使之能与有线电视行业的具体情况相适应。这一点是许多设计人员感到十分困扰的地方,他们迫切需要
Application Requirements: With the rapid development of the cable television industry, the number of users and the business scale are constantly expanding. The fundamental to the survival of the industry: the management of “network resources” is an important issue that cable television stations (companies) face. The related work is the design and management of a large number of drawings faced by network engineering designers. Drawing design from the initial complete hand-to-computer-aided design, the designer’s labor intensity is declining, but the quality of the work is significantly improved. The use of computer design software is almost a basic skill that must be mastered by cable designers. At present, many drawing designers use AutoCad as a tool for designing network drawings, and the powerful drawing function of AutoCad is enough to solve various problems required in the design. But most designers are faced with the problem of being proficient with AutoCad and making secondary development on AutoCad so that they can be adapted to the specifics of the cable industry. This is where many designers find it troubling and they urgently need it
