Program for 3D PIPING SCALE MODELS

AutoCAD Package is prepared in such a manner that it can be easily customized. 3D PIPING SCALE MODELS is such a customized program in my PROGRAMS for PIPING Series, for AutoCAD 2000 to 2008. The program is based on AutoLISP / VBA programs and around 3000 symbols or blocks are created (with insulation) as and when required and then inserted. The pipe line is cut in that portion. Since blocks are created when required, there is a lot of saving of Disk space. 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.


Model Created using 3D Program
See other Views of the Model.

Buying Instructions : You can send the payment through Credit Card by PayPal, Xoom or Bank Transfer. As soon as I get the money, I will send Package by Email. To Buy for details.

Package for ASME (ANSI) Standrard Fittings.
The program based on ASME fittings is priced at 200 Euros.

Package for TRI-CLOVER Fittings.
The program based on Tri-Clover fittings is priced at 100 Euros.

To run this program unzip / copy all files from piping3d_demo file in support directory of AutoCAD. 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 acad\support and click on arrow of Files of Type box. Select Menu Template (*.mnu) and select pipe3d_mm or pipe3d_inch as menu to be loaded. Click on load button. Click yes to continue. Click on Menu Bar tab. Insert all menus in left box one by one, at the end of items in menu bar box. Click on close. Pipe3d menu will be loaded at the end, and start using pull down menu. The last pull-down menu, pipe3d, has all the pipe3d drawing options. The other menu items are not modified.


 3d Piping pull down menu looks like this. Click on Load Programs. 3D Piping programs will be loaded and message will appear on command line.

You have to load programs only once and then you can use all options of 3d piping.

To create 3D Piping Model, first enter line numbers. Click on Line Number > Add. A dialog box will appear.

Enter a new line number in text box and press OK. The line number will be added to the list. Add any number of line numbers. After line numbers are added, press Cancel. The dialog box will disappear. (You can edit or delete line numbers). Click on Line Settings and a dialog box will appear.

 Select the line you want to draw by selecting its line number, the size of the line in NB. Enter insulation thickness in text box and press OK. A message will appear on command line.

Please check the 3 values are properly set (or else redo the process). If a Pipe line is not insulated, insulation thickness should be 0. Using Line command, create a Single Line in 3D with proper elevations. The line is set on a layer having layer name as line number. Once single line is created, insert pipe fittings. In each case a block is created by the program and inserted at the insertion point. Create all pipes at the end using AutoPipe option (or individually as onr pipe at a time)

3D Pipe : There are 5 options for this.
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.

3D Pipe Create Pipe : This ask to select pipe line, and draws the 3D Pipe Line with insulation. Use this option after all the fittings are inserted.
Stretch Pipe : This option uses stretch faces option. To stretch a line in or out, select the pipeline (or insulation), use remove option and click on line (or isulation). Do not click on end, as this is to be strtech. Select center point of end to be stretched and a new point. The pipeline (or insulation) will be stretched.
Auto PipeLine : This asks you to select a pipe. After selecting pipe, it draws the 3D Pipe Lines with insulation for all pipes on that layer of this size. Use this option after all the fittings are inserted.
Lift Pipe : This lifts the pipe line. If the elevation of the pipeline you have drawn is that of bottom of pipe, this option lifts the line to centerline elevation of pipe. It first asks for UCS. For horizontal lines, select top UCS. It then asks to select pipe NB, and lifts the pipe up by half the outside diameter of the pipe.
