Study Of Process Chart CAD On Oil-Gas Field Surface Engineering CSCD

Oil-gas field surface engineering is a system with dense fund and technique,A design task need to be completed by designers who in different locations and different specialty.Oil-gas field surface engineering CSCD is a system based on network,according to the demand of project,which organize different designers to work on the same plat.CAD is the drawing tool,but it need to be secondary-developed if applied to oil-gas field surface engineering CSCD efficiently and conveniently. This paper use some latest technique,such as oil-gas field surface engineering,modern computer science and network communication to study collaboration work,computer supported collaborative design (CSCD ) and AutoCAD secondary-developed theory and method,develop an oil-gas field surface engineering process chart CAD. Oil-gas field surface engineering CSCD includes network ,management module ,database module ,Collaborative tool module and design tool module.Network is the supporting environment,management module dispatches and organize and coordinate the design process,database module save all the shared resources,design tool includes oil-gas field surface engineering process chart CAD and other aided tools. Oil-gas field surface engineering process chart CAD is developed based on AutoCAD 2004 by Visual LISP,which analyze the character of graphics and set up familiar graphics library,the graphics have the attributions which are selected in the dialog when they are inserted in the drawing,An equipment database and detail table are produced automatically.The engineering example proves that oil-gas field surface engineering process chart CAD run steadily and is practical and reliable.
