PIPING Isometric Drawings

PROGRAM for PIPING ISOMETRIC DRAWINGS Most CAD packages are prepared in such a manner that these can be easily customized. 4 Programs of OpenPipe are such customized programs. The Iso program is totally based 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 PROGRAM for PIPING ISOMETRIC DRAWINGS further as per your choice. The different piping entities are arranged on layers 1 to 6 (which is compatible with Microstation). Special Dialogue Boxes are created to make the program more user friendly. The drawing can be converted to Microstation DGN format.

PIPING ISOMETRICS PROGRAM can run on Personal Computers, on a Pentium system with 32 MB RAM. PROGRAM for PIPING ISOMETRIC DRAWINGS supports screen, buttons and icon menus, as well as, dialogue boxes. The program is specifically written for any CAD program. PROGRAM for PIPING ISOMETRIC DRAWINGS can not run on Autocad LT.

To try the program, send a request for trial package. The openpipe.zip file contains all program files. There is no setup.exe file as in other packages. To run program, unzip openpipe.zip and copy files in a folder, say iso. To set up program, while running CAD program (it can not run in AutoCAD LT), at command prompt type _options (or _preferences) and press <enter>. It will open a dialog box. Open Files tab (if not open) -> + of Support File Search Path -> Add -> Browse -> Select the folder, select apply and close.

You can select the type of Standard and system you want to use. Once you select it, you can get all the options available.

SETUP: To draw an Isometric Drawing, first run this option from ISO button menu and select North Direction. A drawing with all default values properly set, is 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. Then change P&I D Number as well as GAD Number using ddedit. Whenever program ask for angle of a pipe line, angle is selected in degrees, as per 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: Draw a vessel nozzle with four types of flanges attached to nozzle, 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. PROGRAM for PIPING ISOMETRIC DRAWINGS 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 3600 mm NB, or from 1/2" to 144", using this option. PROGRAM for PIPING ISOMETRIC DRAWINGS will set layer to linesize_1 and colour of layer to cyan. If pipe size in not defined, a dialog box will open and ask you to select size.

Sleeve Sleeve
Sleeve : You can draw a sleeve through a pipe passes. Program asks to select the pipe line, and then you can enter the description of the sleeve in dialog box. PROGRAM for PIPING ISOMETRIC DRAWINGS draws the sleeve, and writes description on top of pipe line.

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

Arrow : To show direction of flow of a pipe line, you can use this option. Pick start point of arrow head on the pipe line and point on the line towards tail of arrow. PROGRAM for PIPING ISOMETRIC DRAWINGS automatically draws the arrow, and writes pipe NB above pipe line.

Triangle
Triangle : If a line is running at an angle other than North / South or East / West, or at an angle in horizontal or vertical plane, you can use this option to draw the other two sides of triangle (These lins are drawn un layer 0). Program draws pipeline joining two end points of triangle and you can continue pipe option and draw the pipe line further. These lines can be used for hatching the triangle.

Box
Box : If a line is running at an angle other than North / South or East / West, as well as at an angle in horizontal or vertical plane, you can use this option to draw the lower two sides as triangle option and the program then asks to select vertical distance and draws a box (The box is drawn un layer 0). A pipeline joining two end points of box is drawn and you can continue pipe option and draw the pipe line further. These lines can be used for dimensioning the box.

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

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

Line Break
Line Break : You can put a line break at the end or anywhere in the pipe line. you can pick up insertion point and line break is inserted.

Pipe Support
Pipe Support : Program asks to select pipe line. If line is inclined, PROGRAM for PIPING ISOMETRIC DRAWINGS marks a support at the point selected, an arrow pointing upwards, and writes Cl of support. If line is vertical, PROGRAM for PIPING ISOMETRIC DRAWINGS draws a horizontal line from that point and writes PS.
