To provide a better understanding of the scope, information requirements and usage scenarios an informative application activity model AAM is added to every AP, using IDEF0. These interpreted models are constructed by choosing generic objects defined in lower level data models 4x, 5x, 1xx, 5xx and adding specializations needed for the particular application domain of the AP.
The common generic data models are the basis for interoperability between APs for different kinds of industries and life cycle stages. But because the development of an ATS was very expensive and inefficient this requirement was dropped and replaced by the requirements to have an informal validation report and recommended practises how to use it. Today the recommended practises are a primary source for those going to implement STEP.
Originally its purpose was only to document high level application objects and the basic relations between them. And because APs are developed by different groups of people it was always an issue to ensure interoperability between APs on a higher level.
The Application Interpreted Constructs AIC solved this problem for common specializations of generic concepts, primarily in the geometric area. Modules are built on each other, resulting in an almost directed graph with the AP and conformance class modules at the very top. AP , Electrotechnical design and installation. Baseplate Length: Create the pump and position it at: Click on the button on the main tool bar to display the Define Axes form.
On this form, select Cardinal Directions:. An E,N,U axes symbol is displayed at the origin of the current element. The horizontal suction nozzle points north. To change the orientation of the pump so that it points West, click on the Model Editor button on the main tooolbar. Using the left-hand mouse button, click on the pump to display the drag handles. With the pointer over the horizontal rotation handle see above , press and hold down the left-hand mouse button and move the pointer which changes shape in an anticlockwise direction until the following pump orientation is achieved:.
The pump now points West. Click anywhere in the graphics area to remove the drag handles.. See the online help for a full explanation of all of the element position manupulation facilities available in Model Editor mode. Other methods of changing orientation are explained below. Move the pump back its original orientation first by clicking on the Undo button on the main toolbar.
Click again to leave Model Editor mode. The Rotate form enables you to rotate the equipment through a specified angle about a defined axis. The default axis is up, through the origin, and is correct, so just set Angle to This leaves the axes symbol in the 3D View: Navigate to each pump nozzle in turn and rename: Check the layout of the three equipment items in the graphical view:.
It is good practice regularly to save changes to your design as you build it up. This avoids the need to start all over again in the event of loss of work due to an unforeseen interruption, such as a power failure.
You should also save your current screen layout and display settings, so that next time you use the application you can easily. You can now leave PDMS and return to the operating system. Ordinarily, if you had made any changes since your last Save Work operation, an alert form would ask whether you want to save those changes; this time, you are just asked to confirm that you want to leave PDMS.
In the next chapter, you will add to the design model by creating some piping components. To ensure design consistency and conformity with predefined standards, the basic definitions of all items that you can use in the pipework design are held in a Catalogue database. This holds definitions of: When you add an item to your design model, you store the position, orientation etc.
The dimensions of each item are defined in the catalogue by parameters whose values are set only at the design stage, so that a single catalogue entry can represent a whole family of design components which differ only in their dimensions.
You have already used this concept when creating the equipment nozzles in the previous chapter. In each case, you: Each of these is explained in turn below. Each Pipe can represent any portion of the overall piping network, while each Branch represents a single section of a Pipe which runs between two, and only two, points the Branch Head and the Branch Tail.
The individual piping components defined in terms of their catalogue specifications are stored as Branch members. So, a Pipe which incorporates a Tee, for example, must own at least two Branches to achieve the necessary three connection points.
The following configurations show two ways of achieving this solid lines represent part of Branch 1; dotted lines represent part of Branch 2: These tags, which have both position and direction, are called p-points.
Each p-point is identified by a number of the format P0, P1, P2 etc. P0 always represents the component origin position, while. The values of these are defined to suit the specific design requirements.
P1 P1 P1 usually also p-arrive usually also p-leave. The dimensions of the tee are represented in the catalogue by parameters whose values are determined by the nominal bore required to suit the design.
It is assumed from now on that you know how to use the OK, Apply, Cancel and Dismiss buttons on forms, so they will not always be mentioned in the rest of the exercise. When loading is complete, your screen should look the same as it did when you saved the layout in the previous chapter. The alternative is to to reload the applications from their source macros, but this takes more time. The menu bar for the Equipment application is replaced by that for the Pipework application.
The menu bars for both applications are superficially similar, but the latter gives you access to options with specific relavance to creating and manipulating piping components. The Default Specifications form, which is shown automatically is described in the next section. When you select components from the piping catalogue as described earlier in this chapter, you do so by stating which Specification the components must match.
To avoid having to specify this data again for each component, you can set a Default Specification at Pipe or Branch level. This will be used automatically at lower levels unless you override it the default specification is said to be cascaded down the hierarchy. As an example, the specifications which form part of the sample project within which you are working include: The project specifications include some choices for pipework Insulation, but no trace heating specifications as shown by the None Available entry on the Tracing option button.
You do not want to use insulation or trace heating, so make sure that both of are unselected, as shown above. When you click OK, the current default specification is shown in the second row of the tool bar:. The initial sequence will include a tee to which another pipework sequence will be connected later. The configuration which you will create with all components in a horizontal plane is as follows:.
Flange 3 Flange 2 N S Gasket 3 Gasket 2 W You will represent both this and the next sequence by a single Pipe element in the design database, but you must subdivide this into two Branch elements to allow the flows into the pump to combine at the tee. You will define the branches as follows: It will consist of the following components, listed in head-to-tail order: Note that the flow through the tee will enter at P1 and leave at P3 that is, p-arrive will be P1 and p-leave will be P3. The tubing which runs between the piping items shown by the dotted lines in the diagram , is added and adjusted automatically by PDMS to suit the positions and specifications of the components.
You do not have to create it explicity; it is referred to as implied tube. Refer back to the sequence in the diagram when necessary to understand the logic of the following steps for creating this in the design model.
For interest, click the Attributes button to see the types of optional information that you can associate with a pipe definition in the database. Most of these are self-explanatory. You will see that you can specify most of the data needed to fully define a piping network ready for construction and erection; this data will then be cascaded down to all lower levels as you create the piping components.
You will leave all detailing attributes at their default settings, so Cancel the form when you have looked at it. Name the pipe Pipe-1 and OK its creation. You want to connect both head and tail of the branch to existing nozzles, so set the option to Connect.
When you OK the branch creation, you will see a Connect Branch form which lets you specify how the head and tail are to be connected. Set the Connect Branch form to show that you want to connect the Head to a Nozzle, as follows:. Notice how the route of the branch is shown in the graphical view by a broken line. As you have not yet introduced any components, this runs directly from the head to the tail.
You will now build up the component sequence by creating individual piping items. Dismiss the Connect Branch form. The Piping Components form allows you to control all operations for specifying a pipe run. As well as letting you select the type of component required, this form includes facilities which let you access some of the menu options for positioning and orientating the current component:.
You will first set up those parts of the form which will remain the same for all components in the current branch. The top section of the form, Specifications: Piping, Insulation and Tracing the same as the Defaults Specifications form which you used earlier , lets you change the specification for individual components if required. Leave the settings as they are. The order in which the individual components occur in the branch members list is very significant, since it determines how implied tubes are routed between them.
This order is determined initially by the order in which the components are created. You are going to create the branch members in head-to-tail order; referred to as pipe routing in Forwards mode. It is sometimes necessary to work in Backwards mode in tail-to-head order , as you will see later, but this needs more care if you are to avoid mistakes.
Always work in Forwards mode click the Forwards button where possible. Make sure the Default check box is not selected. This means that you will fully specify each component as you create it, rather than relying on default selections predefined in the catalogue specifications.
Select the Auto Conn check box. This will connect each new component to its predecessor automatically as it is created assuming that such a connection is valid. You are now ready to start creating the individual piping components. Select Gasket from the list of component types and then click the Create button. An appropriate gasket will be selected from the current specification, and will be positioned at, and connected to, the branch head. You will not see this in the graphical view because the gasket is too thin to have a geometric representation, but you will see it in the Design Explorer.
Now select Flange and click Create again. Because the A3B specification includes more than one type of flange, you will see a Choose form showing the choices, like this:. The default information given on the Choose form is rather terse. Click the Create button on the Piping Components form again to. Select WN and then click OK to complete the creation process. The new flange Flange 1 in the schematic diagram will appear in the graphical view as well as in the Design Explorer.
The next item you want to create is an Elbow, so select this from the list and click the Create button. From those listed on the Choose form, select type E. When the elbow has been created, the graphical view will show it positioned like this: While the auto-connect function positions and orientates the elbow so that its p-arrive points towards the preceding flange, the application has no way of knowing which way the p-leave of the elbow is to be directed, so it assumes the default direction as set in the catalogue.
To specify the required orientation, select one of the following from the lower part of the form: Rotate Note: Even if the option you want to use is already displayed for example Direct N , you must select it again to carry out the operation. Alternatively, use the rotation drag handles see step 84 to rotate the elbow until it is pointing towards the pump nozzle.
Release the mouse button when the orientation direction is N. You also want to position the elbow at a specified distance from Flange 1. To achieve this, select Position: Alternatively, use the positioning drag handles to reposition the elbow. Select Align with Feature from the shortcut menu on the X handle, then move the pointer so it is over the P1 direction of the Nozzle. Your display should be similar to that shown below:. The elbow is repositioned as follows: You will look in more detail at the ways of positioning and orientating items in some later parts of the exercise.
To save time, a number of common configurations of piping components have been predefined so that they can be created in a. One such configuration, or assembly, consists of a flanged valve, together with the pipe flanges and gaskets needed to connect it. On the Piping Components form, select Assemblies.
When you click Create you will see a Standard Assemblies form listing the available configurations: Apply the Standard Assemblies form settings. You are presented with three Choose forms in succession, which will allow you to select each assembly component in turn.: The piping network now looks like this: Dismiss the Standard Asemblies form. Now create a Tee. Note that this list includes one special item shown as having PBOR3 set to 1.
Select this as the required type. When created, the tee is positioned and orientated as follows:. Flange 3 Flange 2 Gasket 3 Gasket 2. You want the tee outlet p-leave to be P3 rather than P2. You will see a Modify Route form giving the following options: P3 P3 P3. Route through Branch off Split route default. Select Branch Off and notice how the branch route leaving the tee moves from P2 to P3 when you apply the change.
Dismiss the Modify Route form Orientate the tee, using either the Orientate or Rotate option on the Piping Components form, so that its P3 direction is East. To align the tee with the pump nozzle, you can use the Position options in several ways. Use any one of the following but read them all so that you understand the principles: Alternatively, use the positioning drag handles to reposition the tee.
See step for an example of this operation. The resulting pipework layout now looks like this:. Note that a length of implied tube is now shown between the tee outlet and the branch tail, even though the final components have not yet been inserted.
This confirms that the alignment and bore sizes of the tee outlet and branch tail are compatible. Complete the branch by adding a weld-neck flange and gasket, connected to the branch tail, by selecting Flange Gasket to Tail from the Assemblies options and selecting a WN Flange.
The result is: The broken line marks a change of view direction: Notice how the branch route goes automatically to the free connection on the tee; you do not have to pick any particular point on the tee when you connect the tail.
Create a gasket and flange connected to the branch head: Create an elbow: Orientate and position the elbow so that its leave connection is aligned with the branch tail for example, Rotate and Thro Tail.
Implied tube is now shown between the elbow and the tee, confirming that the alignment and connecting bore sizes are correct. Create the valve and its associated flanges and gaskets as an assembly: On the Choose forms, choose: Zoom in on the pipework to see your completed design model.
This completes the introduction to the basic pipe routing operations. In the following parts of the exercise you will look at some ways of checking the design model and outputting some design data derived from the database settings. In this chapter you learn about: These facilities are available from all Design applications, so you can readily check and output data from any combination of design disciplines.
The data consistency checking utility reports the following types of occurrence and other similar errors in the design:. Flanged Screwed connection connection. ANGLE p-leave y. You can specify maximum permissible values for any of these parameters, as well as minimum acceptable lengths of tube between components.
You can specify different minimum lengths for different bores if you wish. If any part of the design falls outside the current limits, an error message will warn you. You will see a Data Consistency Check form.
View the default values for piping design tolerance settings by clicking the Parameters: Piping… button to display the Piping Consistency Check Options form. You will use the default values for all piping design tolerance settings, so have a look at them then Cancel the form. You can send the error report either to your screen or to a file. You will view it on screen, so select the Output: Terminal button.
The Check: You will check each branch separately, so select Branch from the list. The resulting diagnosis is shown in the scrollable text area at the bottom of the form. There may be messages about unknown SKEYs, but ignor these.

The result is appended to the preceding report. The types of clash identified depend on two factors: These categories are: This usually means that a definite interference exists.
This may simply mean that one item is resting upon another as intended, or it may indicate a problem. This represents a near miss, which you may want to investigate. These three classes are illustrated below for the clash specifications: Touch limits: Items which are not in the obstruction list are ignored during the clash checking operations. By default, the obstruction list includes all elements in the database, so that each element to be clash checked is tested against every other element.
To highlight the locations where clashes are found, the clashing and obstruction items are shown in contrasting colours in the graphical view two shades of red, by default. You will use the default values for all clash checking settings. Think about the meaning of each setting shown refer to the preceding introduction ; then Cancel the form.
Remove all current entries and then Add the equipment zone. You will see a Clash Display form. The left-hand side of this form controls the clash checking process; the right-hand side consists of a 3D view in which you can look in detail at any clashes diagnosed.
In your case this should simply say None. If the Auto Clash button on the main toolbar is set to On, each new element that you create is checked immediately for clashes as the design is built up.
This can slow down progress when you are adding many new elements, but is very useful when you want to add a few new items to an existing design which has already been checked for clashes. The reporting utility lets you read selected information from the database and present the output in a tabulated format. Each report can be customised by specifying some or all of the following: Once such a report has been designed, its specification can be saved for future use in the form of a report template file.
The ways in which you define how a given report is to be generated and presented are beyond the scope of this exercise, but you will look at the results of the process by using a pre-prepared template which outputs a material take-off list showing the length of tube needed to build your design. You will probably use your company standard templates for most reports anyway, in which case this is the method you would normally use in practice.
You will see a File Browser listing all files in the current reporting directory specified by your System Administrator as part of the project set-up procedure. Check that you are in the All files with a. Click OK on the File Browser. To run the report defined by the chosen template, you must specify two things as determined by the rules within the template: When you clicked OK on the File Browser to specify the template, a Report Details form appeared which lets you do this.
Leave the Filename text-box empty which will send the report to the screen automatically. Click OK to run the report. The tabulated report output will be displayed in a Command Output window which is opened automatically, like this:. This report shows the number of each type of component used in the design and the total length of tube needed to interconnect them. Do not worry if part of the heading seems inappropriate for your project; this wording is written into the template simply as an example of the type of heading which you might want to use.
The isometric plotting module of PDMS provides very powerful facilities for generating any specified isometric view of all or part of the pipework design, with associated parts lists and annotation, with a very high degree of user control over the output format. You will use just a small part of this power to produce a plot of your design using the default settings only.
Before you proceed further, you must have carried out the data consistency checks specified in Steps to and achieved an error-free report. When loading is complete, you will see the Isodraft menu bar like this:.
This deceptively simple menu gives you access to a wide range of facilities for generating customised isometric plots to suit all likely purposes. For the purposes of this exercise, you will simply generate a standard isometric for the whole pipe i. You will see a Standard Isometric form which lets you specify which parts of the piping design are to be detailed in the plot and which of the standard drawing formats is to be used. Select Standard iso option: MET, like this:. The status bar will display the message Please wait, detailing in progress while the isometric view is composed, the dimensioning annotations are calculated, and the material take-off report is compiled.
On a large process plant model this could take a few minutes, but with your very simple model it should take only seconds. When processing is complete, the following new windows will be displayed: In your case there is only one, so it is selected for display automatically, thus:.
The current display should look like this:. The same data is also sent automatically to a file in your current operating system directory, ready to be sent to a plotter if a hardcopy version is required. Such files are named by default with a sequential number of the format plot00x, where x is incremented from 1 in this case plot Page size printed plots of all three isometrics are in the appendices.
You should now have an insight into the potential power of PDMS and sufficient confidence to explore some of the more advanced options on your own. For further technical details, refer to the sources of information listed in Appendix. If you have not already done so, you are strongly advised to attend one or more of the specialised PDMS training courses, which will show you how to get the maximum benefits from the product in your own working environment see Section 1.
Elements shown in italics, BOX for example, are Equipment items. Therefore, it describes only the main concepts needed to get you started. Documents that can provide you with further information are listed below. The complete set is: These manuals also describe the underlying command syntax which can be used to control PDMS directly should you wish to bypass the forms and menus interface.
