This functionality will be intelligent and allow the user to select either the line or specific components to change. 
  • It will know if a reduction is needed, or if a line needs to be moved and allow the user to make the appropriate decision to accomplish the desired change.

Auto Routing

  • As a user routes a line through the model the program will place the appropriate components required. The user has the ability to add branches, inline components, and sub assemblies as they route the line.
  • There is also the ability to have the program automatically route a line between two points in space. The user can choose which one of the various routing options best meets their design needs.

New and Enhanced Catalog of Components (old DAT Files)

  • The component catalog has been developed to better manage the vast amount of data needed in the design of piping systems. The catalog is divided into three separate catalog groups any one of which can be used. The global catalog contains all components. The industry catalog contains a subset of the global catalog. The company catalog contains a subset of the industry catalog. Each of these can be edited by the user to add or change the component data. As the user creates their company standard catalog components are copied from the appropriate industry catalog. They can have any number of catalogs defined.
  • The catalogs contain three key data types. The first is always required and is used to represent the components graphically. The second type is called enhanced data and is used to allow the representation of components in an enhanced state. The third is for user data and is open to allow for specific user information to be added and used as non graphical information. Each of these types is editable by the user as needed.
  • The data fields can contain formulas as well as variables to enhance the data needed.

New and Enhanced Specifications

  • The specifications for a project will be stored in a single database file called a project spec. This file will contain all the specifications needed for a single project. It will contain all the data from the catalog for each component selected. It will also allow the easier transport of project specifications between users. This will allow a company to have a single file containing all their standard specifications for easier management of standards.
  • The specifications will contain a rules section that will allow the user to specify how the piping systems work together. The rules section will contain a branch table that can be used to restrict the use of various branch components. The branch table will be used for Auto Routing as well. These rules can be turned on or off as needed.
  • For each specification there are several global fields that the user can fill to capture different requirements. The user also has the ability to set the layer, color, and linetype attributes if desired. Visual effects are also included in the specification which allows for different specifications to be represented in different ways such as single line to solid, standard to enhanced mode, and etc.

Minimum and Maximum Pipe Lengths

  • There are data fields in the catalogs and specs that allow the user to set a minimum and or maximum pipe length. These lengths will be used with the piping rules to restrict the lengths of pipes used. If the length is too short it will not allow it to be placed. If it is longer than the maximum then another pipe will be added.

Self Aware Components

  • Each of the components will know what other components it is attached to and keep these connections as it is moved. The user can move any component and the attached components will move with it. If the user moves a component and the attached components need to change orientation they will automatically change.

Piping Rules

  • There are many piping rules that can be set to auto, manual, or off. These rules control many aspects of the piping system including branches, connection types, pipe lengths, and how the piping system reacts to changes. The user can select which rules to allow and which to ignore.

Enhanced Settings

  • There are many new settings which enhances the ability to control the operations of the model.
  • Some of these settings include the ability to control the addition of flanges to valve sets, automatically change spec and size to the attaching piping, control the visual representation of the piping from single line to solids.

New component attributes

  • New component attributes are available to allow for the control of components individually.
  • These include representation such as single line to solid, standard mode to enhanced mode, as well as control of the layers, colors and if appropriate linetypes.

Import of previous data

  • Both the data files and the specifications from previous versions of CADWorx can be imported and used. Because the new catalog and specifications contain new and enhanced data, the user will have to add some additional data to make it totally compatible.

Existing functionality is kept

  • All the existing functionality of CADWorx 2012 is kept in place so the learning curve for CADWorx 2013 will be minimal. All of the palettes will still exist although some are enhanced to address the new functionality.
  • Current interfaces to CAESAR II, ISOGEN and PV Elite have been kept.
  • Design Review can now view published Smart Plant Review VUE files as well as the CADWorx 2013 models.
