Program for Drawing Process & Instrumentation Diagrams

AutoCAD Package is prepared in such a manner that it can be easily customized. Program for Drawing Process & Instrumentation Diagrams is such a customized program in my PROGRAMS for PIPING Series, for AutoCAD 2000 onwards. The program is based on AutoLISP and symbols or blocks are created as and when required and then inserted. Bill of Material is created by a VBA program, which creates a table in MS Excel. In case of valves, the pipe line is cut in that portion. Since blocks are created each time, there is a lot of saving of Disk space. Since the program is written in AutoLISP, it can be even modify further. The different pipe lines are arranged on different layers. This is a menu driven program. Special Dialogue Boxes are created to make the program more user friendly. The program is reasonably priced at 100 Euros.
