I offer a Drawing program which Draws a detailed drawing of Components of a Chemical Process Vessel, with user friendly dialog boxes, which is an add-on for any CAD program. It is useful for adding components to GA drawing of a Chemical Process Vessel. The Program asks for some parameters and draws the Components. Program for Drawing of Chemical Process Vessel draws the GA drawing and components.
To run the program, unzip particular zip and copy files in one folder on hard disk (and not on desk top), say vessel. While running in CAD program click on tools ->Options (or Preferences) -> Files -> + of Support File Search Path -> Add -> Browse -> Select the folder (vessel), and click on apply. Use APPLOAD command to load the program. Program will be loaded. Command line will indicate how to start program.
The drawing program can be used to draw GA of the vessel. You can draw add-on items like, Shell, Heads, Nozzles, Manhole, Lugs Legs or Saddle, etc. on vessel GA drawing. In most drawings, location of nozzles is not indiated intially but it can be added any time later.
You can draw either in Foot-Inch units or in Metric Units. In Metric system it asks for all values in millimeters and in Foot-inch systems it asks for all values in Foot-inch.
