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. Most inexpensive CAD program like BricksCAD, ProgeCAD, IntelliCAD, Draftsight, CADLogic, or ZWCAD 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.
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: 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: Flat 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. Circular 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. Sight Glass: You can draw sight glass with Double Window or Full View with this. Select Pipe Dia from dialog box. Select on pipeline, the center point of flange and a point in the direction of the sight glass. A Sight Glass will be drawn and pipe will be cut.
Steam Trap: You can draw Steam Trap of Ball Float or Thermodynamic type with this. Select Pipe Dia from dialog box. Select on pipeline, the center point of flange and a point in the direction of the Steam Trap. A Steam Trap will be drawn and pipe will be cut.
Strainer: You can draw Line Strainer of Y type (flanged), Y type (socket welded), Y type (screwed) or Basket type with this. Select Pipe Dia from dialog box. Select on pipeline, the center point of flange and a point in the direction of the Strainer. A Strainer will be drawn and pipe will be cut.
Elbows: You can draw: Tees: You can draw: Reducers: You can draw: Weldolet :
You can draw a Weldolet with this. Select NB of main pipe and side pipe. Select a Point on Main Pipeline, then a point on Side Pipeline and the Point of Intersection of two Lines. Weldolet is drawn at the intersection of two lines and pipe will be cut. Coupling :
You can draw a Coupling by selecting a Point on Main Pipeline, then a point on Side Pipeline and the Point of Intersection of two Lines. Coupling is drawn at the intersection of two lines and pipe will be cut. |
