  Getting Started – Setup and Configuration CHAPTER 1

Introduction •

This section will outline the general setup and configuration of CADWorx Plant 2010. It will give you information on setup procedure, toolbars and how CADWorx and AutoCAD Interact with each other.

CADWorx Configuration •

CADWorx PLANT can be run from any location on any directory (network or local). The user has to add all support search paths that might be required to find certain project or job folders. These search paths can be added or modified from the CADWorx Plant profile. CADWorx Plant uses the AutoCAD command line switch /P (User Profile) for starting and running within AutoCAD.

•

"C:\Program Files\AutoCAD 2010\acad.exe" /P CADWorx_Plant_2010

•

The installation program will automatically create a CADWorx_Plant user profile. The profile can be created manually by adding the support file search paths (show below) and the template file location.

Getting Started – Setup and Configuration

•

The CADWorx Plant support directory has to be first in the search path because the ACAD.RX file used to load CADWorx Plant is found in the \SUPPORT directory. The ACAD.RX file is a text file that AutoCAD uses to load ARX routines. If the user wants another support directory to be first, copy the ACAD.RX file into that directory. The CADWorx Plant menu is loaded by the ARX file.

•

Note: To setup the profile for another user login on the same machine, fun the utility SETUP_PROFILE_Plant.exe. This utility is located in the root install directory of CADWorx Plant.

•

Important Note: Drawings should not be opened in the \SUPPORT sub-directory with CADWorx Plant. If a drawing is started in this directory, an error will be reported indicating that the program should not be run at this location. The purpose of this message is to stop CADWorx Plant from initializing or preparing the support drawings. Open a base AutoCAD session for modifying these drawings.

•

If you need to edit one of the blocks or templates, use AutoCAD without CADWorx or move to a different folder.

CADWorx Startup •

Now that we have briefly gone through the setup of CADWorx we can now double click on the CADWorx Plant 2010 icon to start CADWorx. For this exercise pick the Metric_3d.dwt. When making a new template make sure you use AutoCAD and not CADWorx to generate the DWT file.

Note: The 3D templates only add predefined tiled viewports. You can use the standard Imperial or Metric templates for 3D modeling.

•

You have now successfully started CADWorx/Plant. The first time you run the application, the AutoCAD screen environment should look familiar to you. However, there will be one additional pull down menu, “Plant.”

Getting Started – Setup and Configuration

Note: You will have access and use of all AutoCAD tools and commands.

CADWorx Productivity (Tool Bars Options) Option 1 – Conventional Tool Bars •

Tool bars are one of the most productive and direct means to access piping components, settings, and modeling tools. The size of your monitor and personal preference will dictate the best layout.

Option 2 – CADWorx Spec View (New for CADWorx 2007 to 2010) •

CADWorx Plant components are typically drawn using toolbars, or by typing the command name at the AutoCAD command prompt. The SpecView palette provides an alternate method of inserting CADWorx components. SpecView will filter the available components based on the size and specification settings. In addition, SpecView also provides a quick way to change the line number setting.

Getting Started – Setup and Configuration

SpecView Pallet

Option 3 – Customizing Tool Pallets •

Customizing AutoCAD’s tool pallets to suite your needs is another option. This allows you the flexibility to make your own arrangements of commands.

•

Note: Besides the pull down menu and the toolbars, CADWorx/Plant has a rich collection of “Aliases.” The aliases are defined in the “Pipe_Alt.pgp” file in the application’s support directory.

CADWorx Plant RIBBONS •

The new ribbons have been added in the recent November build of CADWorx 2010. These ribbons can be turned off if the user wishes.

CADWorx Plant I Ribbon

CADWorx Plant II Ribbon

CADWorx Plant III Ribbon

•

We now have our menu system in place and are ready to look at settings. The master settings dialog, “CADWorx PLANT Setup”, is available from the Plant pulldown and also the first button on the Setting toolbar or from the new ribbons setup.

•

The CADWorx PLANT Setup dialog is divided into a number of sections:

Getting Started – Setup and Configuration

User Border •

This button provides a file selection dialog for choosing the required border. The user can navigate through this dialog to locate any user border or to choose one of the default CADWorx Plant borders.

Predefined •

This button supplies the list of drawings in the Predefined borders list. The drawings list is retrieved from the MVSETUP.DFS file located in the \SUPPORT directory. The MVSETUP.DFS must be located in the first search path of the ACAD support directories.

User-Defined •

This button provides the User defined border box and allows the user to define a simple rectangle that will be drawn upon exiting these dialogs.

Paper Space •

This toggle causes the border to be inserted in the paper space.

User defined border •

These edit boxes define the size of the user border. The border will be a simple rectangle. The Plotted X length and the Plotted Y length will dictate the overall height and width of the border. The rectangle will be drawn with the PLINE command. This edit box will not be available if the User defined button above is not selected.

CADWorx Seminar Notes – Chapter 1

Page | 8

Getting Started – Setup and Configuration

Border insertion location •

These edit boxes supply the X and Y coordinates for the insertion point of the border drawing. These boxes will be greyed if the No border button is selected.

Predefined borders •

This list is provided when the user selects the Predefined button. As mentioned above, the list is created from the MVSETUP.DFS file.

CADWorx Scale •

This list box displays all the available scales listed in the Format list box (description follows). By selecting the desired scale, the Scale, Textsize and LT Scale edit boxes will be filled in with the appropriate sizes. The scale (DIMSCALE), text size (TEXTSIZE), and line type scale (LTSCALE) are based on the values in the SCALE.DAT file located in the \SYSTEM sub-directory.

Scales affect text, dimension variables, and borders in the Model environment. By choosing a Scale, the proper Scale Factor, Text size, and LT Scale will be set. The “Scales” dialog allows the user to make adjustments to these values. Scales and their values are controlled by the “Scale.Dat” file in the System folder of CADWorx PLANT.

•

Select 1:20 and pick “OK.”

•

The Format list box supplies four different formats to choose from, Architectural, Engineering, Decimal and Metric. Each format updates the Scales list box for the user’s selection.

•

The Scale edit box provides a means of automatically or manually setting the scale (DIMSCALE setvar) of the drawing. By selecting an item in the scales list box, each edit box value will be updated. The user may also type a value in these boxes.

•

The Textsize edit box acts the same as the Scale edit box.

•

The LT Scale edit box provides a means of applying a line type scale as above. When a scale is selected from the list box, this edit box automatically updates.

CADWorx Seminar Notes – Chapter 1

Getting Started – Setup and Configuration

CADWorx Layers •

The following dialog is used for changing the default names, line types, and colours of the startup layers. The user can also add and delete layers here. Some layers are mandatory for use with CADWorx Plant and cannot be deleted. Changes made here will affect the current drawing session similar to the AutoCAD LAYER command.

The list shows the default system layers. Users can highlight a layer in the list and edit its properties using the functions at the bottom of the dialog. New layers may be added to this list. Let’s add one for future use.

•

Pick Add button, Name: Dim3 Color: 1

•

The layers are stored in the configuration file shown at the top of the “Layer Control” dialog under the [Pipe Layer] header

Linetype: Continuous

Name •

After picking a layer name in the list box above, this edit box allows the layer to be renamed. The layer name may be anything that is allowed by AutoCAD. Wild card characters are not allowed.

Linetype •

This button searches through the CFM.LIN and the ACAD.LIN (only if found in AutoCAD search path) and presents all the line types in these files for use in the start-up procedure as shown below.

CADWorx Seminar Notes – Chapter 1

Page | 11

Getting Started – Setup and Configuration Color •

This button provides the standard color dialog for selecting the color of the layer.

Add •

This button allows the user to add any layers required. These layers will be created when the drawing is initialized with CADWorx Plant.

Update •

This button updates the list box after the name of the layer has been changed. Changing focus to another location will accomplish the same effect.

Delete •

This button simply deletes any layer that is not needed. Some layers cannot be deleted which will cause this button to be greyed out.

CADWorx Drawing Mode •

Next, we will look at the other Mode settings and Configuration.

Drawing Mode (Use 2D Double) Fitting Mode

•

(Use Threaded)

Drawing Mode – sets the current representation for components. It does not affect any existing graphics. Existing representations may be converted at any time using “Mode Convert” which is found in the “Accessory” section of the “Pipe” pull down menu.

CADWorx Seminar Notes – Chapter 1

Page | 12

Getting Started – Setup and Configuration •

The Drawing Mode may also be set using the “Setting” toolbar as shown left and in the New ribbon

•

Threaded components. Since Threaded and Socketweld components share the same toolbars, this switch is provided.

CADWorx Configuration File •

To change the default settings, highlight the variable and make the change in the edit box at the bottom of the dialog.

•

The help section of the “Configuration File” dialog details each variable and its possible values. I have also included a copy in the

•

“Resource Data” section at the end of this chapter. CADWorx PLANT allows users to create multiple configurations to meet client’s needs. The default configuration will be “Imperial” or “Metric.” Once all variables are set, use the “SaveAs” button to create a new configuration.

CADWorx Seminar Notes – Chapter 1

Page | 13

Getting Started – Setup and Configuration •

To access the different configurations, use the “Restore” button at the bottom of the “Configuration File” dialog. One of the most important uses or configurations is to set unique locations for specs and libraries used for a particular client or project. Line number schemes are also stored in the configuration along with layering and other project requirements.

Tool Tips •

CADWorx Plant also has Tool Tips available to users. These are controlled by the variable “ToolTipSetting”

•

This variable controls the items the user sees in the tool tip displayed, when the mouse hovers over a component. When selected, the user is allowed to click on the Settings button and select items to view on the tool tip. Eg. Alpha Size, Long description, Line Number, Spec file, Length and Elevation has been set.

CADWorx® 2D – 3D Piping

Starting the Drawing •

We will start with a simple 2D approach, and then look at 3D modeling.

•

We setup a working 2D environment in Chapter 1, TRAIN1.Dwg.

•

(Open if necessary). Just to review our system setup, pick the “Current Setting” button on the Setting toolbar.

This “Current Setting” dialog can also be accessed from the pulldown menu “Plant;” “Utility;” “Setting…” Notice that “Line Number” has not been set. We can set it now or wait till later. For this exercise, we will wait.

1. From the Flanges toolbar, select a Weldneck.

•

Look at the Command Line.

CADWorx Seminar Notes – Chapter 2

Page | 2

CADWorx® 2D – 3D Piping 2. The long description of the component is displayed on one line followed by the placement prompts. Weldneck Flanges are unique in that they have two different endconditions, buttweld and flange. The default placement is varied each time this command is executed; so watch your command line carefully. On this placement the Buttweld is the default and Face is optional because it appears in brackets, [Face end]. We want to place the face of flange first, so enter “F.” Command:

Pick start point or [Face end] : F

Command:

Pick start point : (pick any point)

Command:

Pick direction: (Ortho ON) pick Right (+X)

3. For precision placement of components, we will be using Object Snap. To help speed up placement, we can set “Running Osnap.” Place your mouse over the OSNAP” button on the status line, pick the right mouse button and select “Settings...”

Minimum settings: Options:

Endpoint, Intersection, and Center. Perpendicular and Nearest.

4. From the Buttweld toolbar, select a Concentric Reducer.

Command:

Pick large end point or [Small end] : Enter

Note: Using “Enter” we accepted the default large end and placed it at the last the last running point (buttweld end of WN flange). We could have picked a point using our Running Object Snap.

CADWorx Seminar Notes – Chapter 2

We don’t actual draw gaskets. A symbol is drawn on the System layer to indicate the placement of the gasket, store the material data, and define the gasket thickness. The symbol is comprised of two blocks spaced one gasket thickness apart. The insertion points of the blocks are on the center point of the both faces of the gasket and can be accessed using Object Snap “Insert.” Note: The System layer is normally turned off for plotting (make it a non-plot layer).

CADWorx® 2D – 3D Piping

LINE Numbers We have will now look at Line Numbering. Normally, we would setup and use the system at the beginning of a project (if we could). Before we begin to define our line numbering format, let’s be sure what is meant by “Count.” CADWorx Plant uses this term for the numeric sequence number of the line, i.e. 101. If you are required to use an alphanumeric sequence, just add an additional variable (category) for the alpha portion. We will add one for this exercise. 26. From the Line Numbers toolbar, select Line Number Setup.

This command can also be accessed from the pull down menu PlantÎAccessoryÎLine Numbers; Setup… First - Add a separator, “-.” Then (Type and Add) Second – Select “Service” from the Categories (pick “Add”) Finally –Add “Count” (list) and “Alpha” (type in).

•

System ON should be checked. We will use the System ON in the Dynamic Mode. That is to say, the Spec and Size values will be furnished by the components. In the “System Static” mode, the user can set the Spec and Size values and apply to any component (of any size or spec). We will also set “Default values” for Service (set to HC) and Alpha (set to A). Notice the “Preview” box. Set a value for Count to 101. Note: The Line Number Count buttons only work in the Dynamic mode.

The Category selection set comes from either the DATABASE.TBL file in the System directory or from the P&ID database. 27. From the Line Numbers toolbar, select Line Number Assign.

Pick the entire run of pipe. If a number was previously assigned, you will be prompted (use “All”). The line numbering system will be saved in the present Configuration File. Each configuration can have a unique format.

From the Setting toolbar, select Component Edit or Double Pick on the component.

3D Modeling •

To get the maximum productivity from a piping design application, you need to use 3D. A 3D environment allows easy management of materials and the ability to define the complete geometry of a piping system to produce automatic isometrics. There are a number of ways to change your viewpoint in AutoCAD. We will use the predefined isoviews.

1. Using the AutoCAD View toolbar select “Southwest.”

2. From the pulldown menu PlantÎAccessoryÎMode ConvertÎ3D Solid

The next step involves the use of one of the handiest but least used AutoCAD tools, (XYZ or Point Filters). At any prompt for locating a point, you can enter point filters to specify a single coordinate by extracting the X, Y, and Z values of several points. In the following example, the start point for the line has a coordinate constructed from the X value of the midpoint of the first object you select, with the Y and Z values of the midpoint of the second object you select. As show below we want to connect a pipe from the flange to the tee. You want to make sure if you are going to be using point filters your OSNAP is on as well as your OBJECT SNAP TRACKING. Object snap is set to Endpoint, Extension, and Apparent Intersection.

Automatic Bolts 1. We don’t draw bolts; we just insert data required for BOM extraction. So, it’s just a matter of when do I need the data and how I’m going to get it into the drawing. CADWorx offers three choices for BOLTS

Standard – Reads a size and spec from your settings. Non-Standard – User prompted for Data Automatic – Global procedure where CADWorx will read the gaskets for Size and Spec.

•

The “Automatic” is the preferred choice. The user can globally pick the drawing or line and attach the bolts. Where there is a gasket the letter “B” will be inserted. NOTE: Bleed Rings will yield incorrect automatic bolting information (two sets of bolts with the wrong length; one for each gasket).

A “B” indicates bolt data in the drawing. It’s on the System layer.

•

Bolts can be automatically inserted by the Auto-ISO function if you’re generating CADWorx Isometrics. Isogen requires the bolts be inserted as above. We will look at both options later in the course.

•

There is a system variable, Configuration File, called “BomBoltControl.” This will help set up how you wish to quantify your bolts.

  CADWorx® Automatic Routing & Sloped Lines CHAPTER 3 CADWorx Automatic Routing feature is used to provide a 3dpoly line for welded, threaded and socket automatic routing routines. It will allow you to draw the 3dpoly line with different options. It also provides an undo feature similar to the AutoCAD’s 3dpoly command. The command will control the AutoCAD UCS. When activated, the command will automatically return the UCS to World Coordinates. This will allow the different options to be used correctly like the WORLD feature when prompted to use the ELEVATION. Combining CADWorx Automatic Routing and AutoCad point filters a user can draft in 3D very quickly and accurately.

Pipe routing is a snap. Draw a simple 2D or 3D routing line, then use the built in router to attach pipe and elbows. You can apply piping at any angle in any direction. You can use buttweld (short or long radius), socket weld or threaded components, and apply trimmed elbows quickly and easily. Rolling offsets are a breeze! Additionally, the router gives you all the options you need - sloped, elevation changes and more - to produce clean, logical piping layouts.

Orifice Flanges – (Spec Editing) •

Once the 2” line has been drawn, we now want to place a pair of Orifice Flanges at (900mm) upstream of the by by-pass.

•

Orifice flanges come in wide variety of flange types and use the appropriate pick on the Flanges toolbar. However, since they share the same picks as standard flanges, they have been added to the specification as an “OPTION.”

CADWorx - OPTIONS TOGGLE

•

To toggle this option on requires the user to activate a toggle from the pulldown, PipeÎAccessoryÎSpecificationÎToggle or type SPECOPTION from the command line. There is also a button for it on the Settings toolbar.

Bolts •

As mentioned earlier in this Chapter we don’t draw bolts; we just need to insert the data required for BOM extraction. So, it’s just a matter of when and how to add the data.

•

A “B” indicates bolt data in the drawing. It’s on the System layer.

Bolts can be automatically inserted by the Auto-ISO function (see the “Auto Isometric Config…”).

There is a system variable, Configuration File, called “BomBoltControl.” This will help set up how you wish to quantify your bolts.

This variable controls how bolts are placed in the CADWorx Plant AutoISO bill of material schedules and the CADWorx Plant ISOGEN material list.

BOM – BILL OF MATERIAL •

Why do we want to work in 3D? Hopefully, this exercise has given you an idea of how easy working in 3D can be. Beside a better design environment, 3D is the only sure way to manage material (BOM) and provides us with all the geometry that we need for the automatic generation of Isometric Piping Drawings.

•

The Bill of Material (BOM) utility provides a means to organize and present material data.

1. You can access the command from the PlantÎBill of MatieralÎSetup or from the new CADWorx ribbon.

CADWorx Seminar Notes – Chapter 3

Page | 13

CADWorx® Automatic Routing & Sloped Lines

•

All component data is stored in the Xdata fields that appear in the left-hand box. Using the “Add” and “Remove,” you can select the fields that you require as columns in the material list. Once all columns are selected, use the “Move Up” and “Move Down” buttons to organize the order of the columns. Highlight a column in the list and further define by setting the alignment (radio buttons in the center of the dialog) and define a column title and width at the bottom left of the dialog.

•

“Sort Order…” opens a new dialog to configure order of component entries in the BOM.

2. Highlight the column “MARK” and change the title to “ITEM.”

The “Run” area of the BOM menu allows selection of how we want pipe quantified, “Total” or “Cut,” and also a pick for a parts list (every component will have a separate entry in the BOM).

In the “Tag” menu area you can toggle the tagging function off, change a tag location, or insert a new tag.

Notice the title of the first column? ITEM! This report can be passed to the client or project engineer for material review. Other formats are also available but every engineer that I know is especially fond of Excel.

•

CADWorx has an internal isometric drawing generator, Auto-Iso, as well as the ability to output to Alias’ Isogen (available in Plant Professional).

Using Auto Router for Sloped Lines •

Now that we’ve used the Auto Router for some basic piping, we’ll look at one of the command’s more useful functions, which is when a pipeline has a slope.

•

In this exercise, we will be running a 6”-150# flare header line from a piperack to a Flare Knock Out Drum. Then we will tie in a 3”-150# line from a Free Water Knockout skid into the flare header.

1. Start by opening the model “Sloped Flare” located in the Piping folder of the project. 2. From the “CADWorx/PLANT Setup” dialog set the following: Main size:

6”

Reduction:

Run a 6” Routing Line (Plant-Accessory-Auto Route-Router) from the buttweld of the flange on the building to the buttweld of the flange on the cooler using XYZ POINT FILTERS. Draw the routing line 500mm’s from the buttweld of the flange at the compressor building, then sloping upwards (‘Z & Y’ value of the cooler nozzle) and finishing at the buttweld of the cooler flange.

•

Finish the line using the Plant-Accessory-Auto Route-Buttweld LR command.
