All cad Package are prepared in such a manner that it can be easily customized. Openpipe are such 4 customized programs in my PROGRAMS for PIPING Series, for any inexpensive CAD program like BricksCAD, ProgeCAD, IntelliCAD, Draftsight, CADLogic, ZWCAD or FreeCAD program. It can not run on LT. The program is based totally on LISP programs and there are only 4 small symbols or blocks to be inserted as in other programs, due to which there is a lot of saving of Disk space as well as the drawing also has very small size. Since the program is written in LISP, you can even modify it further as per your choice. The different piping entities are arranged on layers 1 to 6. Special Dialogue Boxes are created to make the program more user friendly.

MINIMUM RECOMMENDED HARDWARE: PIPING ISOMETRICS can be run on Personal Computers, on a Pentium system with 32 MB RAM, under Windows 95 or higher. Also, a SVGA card and VGA Color monitor is recommended. It supports screen, pull-downs and icon menus, as well as, dialogue boxes. The program is specifically written for any inexpensive CAD program like BricksCAD, ProgeCAD, IntelliCAD, Draftsight, CADLogic, ZWCAD or FreeCAD program. It can not run on LT.
INSTALLATION: The program is designed to run under Any inexpensive CAD program like BricksCAD, ProgeCAD, IntelliCAD, Draftsight, CADLogic, ZWCAD or FreeCAD program.
FOOT-INCH and METRIC VERSIONS: Separate Menus are available for this program for Metric Units and for Foot-Inch Units for cad.
HOW TO DRAW with PIPING ISOMETRIC PROGRAM: To run this program copy all files in isometric folder to support directory of cad. If you copy them to some other folder, in cad, click on tools ->Options (or Preferences) -> Files -> + of Support File Search Path -> Add -> Browse -> Select the folder folder. All files from zip file should be in this folder. At command prompt run menuload command (Type menuload and press enter). A dialog box will open showing cad as current menu in menugroup tab. Click on browse near file name text box. Change folder to cad\support and click on arrow of Files of Type box. Select Menu Template (*.mnu) and select iso_mm or iso_inch as menu to be loaded. Click on load button. Click yes to continue. Click on close. iso menu will be loaded, and start using pull down menu. The pull-down menu, iso, has all the iso drawing options.

ISOMETRIC PULL-DOWN MENU: The pull-down menu has all the options of isometric drawings.
SETUP : Run SETUP option from ISO pull-down menu. Select North Direction. A drawing with all default values properly set, will be set-up automatically. The size of the drawing is 420 mm wide and 297 mm high for Metric Units and 17" wide and 11" high for Foot-Inch Units. In the dialog box that appears, enter drawing number, and line number. Change P&I D Number as well as GAD Number using ddedit.
Whenever program ask for angle of line, please select angle in degrees, as per Intellicad or cad Standard angles.(0 degree for East, 90 degree for North, 180 degrees for West, 270 or -90 for South and any other angle in between).

NOZZLE : You can draw a vessel nozzle with four types of flanges attached to it, at any angle, using this option. When you click on this a dialogue box will open, showing the type of flange attached to nozzle. You can have Slip On, Weld Neck, Socket Weld or Lap Joint Flange. Select the proper flange connection. Dialogue Box will close and you are asked to select point location of nozzle on the pipeline and then through a Dialog Box, you can define nozzle side direction angle in degrees. Assign nozzle number or pump number to the nozzle. It will automatically draw a nozzle with flange and gasket and write nozzle or pump number.
PIPELINES: When you click on this, this offers twelve options.

Pipe : You can draw all pipelines with diameter from 15 mm NB to 600 mm NB, using this option. It will set layer to linesize_1 and colour of layer to cyan. Draw similar to line command.

Sleeve : You can draw a sleeve put on a pipe. Program asks you to select the pipeline, and then enter the description of the sleeve in dialog box, and it draws the sleeve, and writes description.

Insulation : You can draw insulation symbol on a pipeline. Program asks you to select the pipeline, and then enter the description of Insulation in the dialog box. Insulation symbol will be put on the line, and description is written on top of it.

Arrow : To show direction of flow of a line, use this option. Pick start point of arrow head on the line and point on the line towards tail of arrow. It will automatically draw the arrow, and write pipe NB above it.

Triangle : If a line is running at an angle other than North, South, East or West, or at an angle in vertical plane use this option to draw the other two sides of triangle. Program will draw pipeline joining two end points of triangle and you can continue pipe option. These lines can be used for hatching the triangle.

Box : If a line is running at an angle other than North, South, East or West, as well as at an angle in vertical plane use this option to draw the lower two sides as triangle option and the program asks to select vertical distance. A pipeline joining two end points of box is drawn and you can continue pipe option. These lines can be used for dimensioning the box.

Slope : To write slope of a line on a pipeline, use this option. Program asks you to select a line, then a point in the direction of the slope, text to be written on line (eg. 1:100) and writes it automatically, after you select the text location, while drawing a triangle showing slope.

Linetype : You can change linetype of a line to continuous, hidden, hidden2, hiddenx2, center, center2, centerx2, phantom and phantom2.

Line Break : You can put a line break at the end or anywhere in the line. Pick up insertion point and line break will be inserted.

Support : Program will ask to select pipeline. If line is inclined, it will mark a support at the point you select, an arrow pointing upwards, and write Cl of support. If line is vertical, it will draw a horizontal line from that point and will write PS.

Change Layer to 0 : If the particular entity is not part of the the line, you can put it to layer zero and change its linetype to hidden, using this option. Program asks to select a number of entities, and then changes the same.

Continue : If the pipeline is not included in this drawing, it can be drawn with this. Line is drawn dotted. The program will ask you to select first point, then second point. Through a dialog box, you can enter line number which appears above the line. You can also enter Drawing number in which that line is drawn. It is written below the line as C.O.D. and line number.
