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, that layer can be frozen, to avoid confusion.

Program for 2D Pipe Routings

Most inexpensive CAD program like BricksCAD Lite, ProgeCAD, IntelliCAD, Draftsight, CADLogic, ZWCAD or FreeCAD 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, program 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 or download from website. The package is a zip file, 2dpipe_trial.zip. There is no setup.exe file as in other packages. Download and unzip 2dpipe_trial.zip and copy files in a folder. While running inexpensive CAD program like BricksCAD Lite, ProgeCAD, IntelliCAD, Draftsight, CADLogic, ZWCAD or FreeCAD program, click on tools ->Options (or at command prompt, type _Preferences) -> Files -> + of Support File Search Path -> Add -> Browse -> Select the folder. Click on Apply and the click on close.
To set up menu for the program, while running any CAD program, at command prompt type menuload and press <enter>. Menu Configuration Dialog box will open. Click on Menu Groups tab. Next to text box File Name, click on browse. Click on down arrow of Files of type box, and select Menu Template (*.mnu). Select either pipe2d_mm or pipe2d_inch, and click on open, Click on Load. For Continue loading MNU file?, click yes. Menu will be compiled and appear in menu groups. Click on Menu Bar Tab, and select either pipe2d_mm or pipe2d_inch. In left side Menu Box, 2d menu will appear. In Menu Bar box, click on windows, and click Insert to load 2d menu. Start using 2d Pull Down Menu.
In BricksCAD Lite, installation is bit different. You can add menu with CUSTOMIZE command and You can load lisp file by APPLOAD command.
OR

At command prompt, open trial.dwg and type (load "2p") and press <enter> or use APPLOAD command. pipe2d will be loaded, and start program by typing 2p and press <enter>.

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 insert pipe fittings.

2D Piping Program: This has 12 options. "2D Pipe (pip)" "Flanges (fla)" "Valves (val)" "Sight Glass (sig)" "Steam Trap (ste)" "Strainer (str)" "Elbow (elb)" "Tee (tee)" "Reducer (red)" "Swage (swg)" "Weldolet (wld)" "Coupling (cop)". The short command are shown in bracket.

2D Pipe (pip) has 5 options:

  1. Add A line Number
  2. Edit A line Number
  3. Delete A line Number
  4. Draw on Line
  5. Multiline Pipe

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. Program 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. Program 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 line number and layer is deleted from the drawing, if line number and layer 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. Program 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.

Pipe Drop : When pipe drops at the elbow, an arc is drawn showing direction of pipe going down. Select NB of Pipe in dialog box as above and then the point where drop will be there. Select a point at back of pipe. Arc will be put at the end.

Pipe Rise :When pipe rises at the elbow, an arc is drawn showing direction of pipe coming up. Select NB of Pipe in dialog box as above and then the point where rise will be there. Select a point at back of pipe. Arc will be put at the end.


Flanges: You can draw Slip on, Weld Neck, Blind and BS10 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 on pipeline 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#, 600# and 800# Gate, Globe, Check, Wafer Check, Ball, Butterfly and control valves with this. Select Pipe Dia from dialog box. Select on pipeline, the center point of flange and a point in the direction of the valve. Select whether you want to draw valve as Elevation or Plan. A valve will be drawn and pipe will be cut.
