2D Pipe Routings

Need for 2D Pipe Routings?: To create a 3D Model, first you have to create concenptual 2D Pipe Routing, with pipe center line elevations marked on each horizontal pipe line. This gives idea about layout in plan view. This can be converted in 3D Pipe Routing, by lifting the horizontal pipe lines to the elevations of the pipe center line. In 3D view, the vertical lines can be joined from end points of horizontal pipe lines.
Generaly one pipe line is drawn on one layer. This helps is segragating pipe lines. When one line routing in 3D is completed, it can be frozen, to avoid confusion.


Program for 2D Pipe Routings

Most CAD Packages are prepared in such a manner that these can be easily customized. 4 Programs of OpenPipe are such customized programs. The 2D program is based totally on LISP programs and no symbols or blocks are created. Pipe line is cut in the portion where fitting is drawn. Since blocks are not there, there is a lot of saving of Disk space. Since the program is written in LISP, it can be even modify further. The different piping entities can be arranged on different layers. This is a menu driven program. Special Dialogue Boxes are created to make the program more user friendly.
To try the program, send a request for trial package. The package is a zip file, pipe2Dd_demo.zip. There is no setup.exe file as in other packages. to Request Trial Program. Download and unzip pipe2d_demo.zip and copy files in a folder. While running AutoCAD program, click on tools ->Options (or Preferences) -> Files -> + of Support File Search Path -> Add -> Browse -> Select the folder. At command prompt run menuload command (Type menuload and press enter). A dialog box will open showing acad as current menu in menugroup tab. Click on browse near file name text box. Change folder to the folder where all program files are located and click on arrow of Files of Type box. Select Menu Template (*.mnu) and select pipe2d_mm or pipe2d_inch as menu to be loaded. Click on load button. Click yes to continue. Click on close. pipe2d menu will be loaded, and start using pull down menu. The pull-down menu, pipe2d has all the 3D piping model drawing options. The other menu items are not modified.

2D Pipe Lines : To draw 2D Pipe routing, first create a Single Line layout. Put each line on a layer having layer name as line number. Then draw pipe fittings.

Line Number : This has 3 options.
  • Add A line Number : When you click on this, a dialog box opens and shows the line numbers (names of layers) existing in the drawing, if any. You can add a new line number in the text box below. It creates a new layer with that name.
  • Edit A line Number : When you click on this, a dialog box opens and shows the line numbers (names of layers) existing in the drawing, if any. You can select the line number to be edited from the list and type a new line number in the text box below. It renames that with a new name.
  • Delete A line Number : When you click on this, a dialog box opens and shows the line numbers (names of layers) existing in the drawing, if any. You can select the line number to be deleted from the list and it is deleted from the drawing, if it is not in use.

Draw on Line : When you click on this, a dialog box opens and shows the line numbers (names of layers) existing in the drawing, if any. You can select the line number from the list. It makes the line number (layer) current, so that whatever you draw is put on that layer.

Multiline Pipe : This draws a line to its thickness. Select NB of Pipe and then pick pipe center line. Two lines are drawn along the center line, at a distance exactly equal to half the outside diameter of pipe. The linetype of the line changed to centerx2. Use this option after all fittings are drawn in that line.

Flanges : You can draw Slip on, Weld Neck, Blind and BS Flanges. You can draw Flat or Circular view with this :

Flange Flat ViewFlat View : Select the NB of Pipe and type and rating of flange. The raised face option is default. Select the insertion point of flange and point at the back side of flange. A flange will be drawn and pipe will be cut.

Flange Circular ViewCircular View : Select the NB of Pipe and type and rating of flange. The raised face option is default. Select the insertion point of flange. A flange will be drawn. Flange will draw to appropriate number and size of bolt holes, at flange pcd.

Valves : You can draw 150#, 300# and 600# Gate, Globe, Check, Wafer Check, Ball, Butterfly and control valves with this. Select pipeline, the center point of flange and a point in the direction of the valve. A valve will be drawn and pipe will be cut.

Globe ValveGlobe Valve : 150# : From 15 mm NB to 400 mm NB.
300# : From 15 mm NB to 300 mm NB.
600# : From 15 mm NB to 300 mm NB.
