PDS PIPING COMMANDS

Posted by Antony Thomas at Wednesday, September 07, 2011

PDS PIPING COMMANDS


The Placement commands enable you to place pipe, piping components, pipe supports, and


instrument components. You can also place assemblies (predefined sets of components).

The Revision commands enable you to move, delete, and rotate existing piping. You can

revise individual components, piping segments, or all of the elements on a pipeline or defined

by a group operation.

These commands enable you to review or revise the model data stored in the Design Database

and Project Control Database. The data associated with each model is collectively referred to

as the Task Database. The Task Database is a working copy of the design data for a project

which corresponds to a design volume within the plant.

Each component in a piping model is linked to a database record which contains non-graphic

information about the component. When a component or segment is placed in the model, the

system creates a row in the appropriate database table.

The Review Revise and Analyze commands enable you to review or revise the model data

stored in the Design Database and Project Control Database. The data associated with each

model is collectively referred to as the Task Database. The Task Database is a working copy

of the design data for a project which corresponds to a design volume within the plant.

Each component in a piping model is linked to a database record which contains non-graphic

information about the component. When a component or segment is placed in the model, the

system creates a row in the appropriate database table.

Command Groups


Placement Commands Places pipe, piping components, pipe supports, and instrument

components. You can also place assemblies (predefined sets of components).

Revise Component Commands Revises/appends different positional and/or task

database information on PDS piping components. Any rotation, addition, or

reconstruction of PDS piping components must be done through these commands and

not through MicroStation manipulations due to the interdependence of graphic and

database information.

Revise Segment Commands Revises piping segments in the active model. The

commands perform both graphical and task database revisions. You cannot use

MicroStation commands to change piping segments as they will not update the user

data associated with the piping segment.

Revise Group Commands Moves, deletes, rotates, and reconstructs existing piping.

You can revise a pipeline of those elements defined by an active group.

Revise Data Commands Revises information in the Design Database and defines


additional information for components. You can only revise information for items in

the active model.

Review Data Commands Reviews information in the Design Database or reviews

existing report files. You can only view the information you cannot make any changes.

Analyze Data Commands Reviews information related to the model analysis

operations. You can also check for interferences within the active model file.


Placement Commands


These commands enable you to place pipe, piping components, pipe supports, and instrument

components. You can also place assemblies (predefined sets of components).

A combination of Sketch, Place Component, Automated Placement, Place Pipe Support,

and the Copy Commands is normally used to model a complete pipeline.


Commands


Using the Placement Commands — Outlines the prerequisites, group workflow, and basic

instructions for using the Placement commands.

Place Component — Manually places components (such as valves or fittings),

piping, instruments, or assemblies.

Sketch — Defines the centerline geometry for a pipeline and define the attributes of

the piping segment.

Automated Placement — Places items such as pipes, elbows, reducers, branch

components, and flanges on the piping segment according to the attributes and the

geometry of the segment.

Add Chain Wheel — Modifies the operator on an existing valve component.

Add to Valve — Modifies the operator on an existing valve component.

Tap Component —Adds a tap to an existing component.

Place Pipe Support — Places physical pipe supports.

Place Logical Support — Places logical pipe supports.

Copy Pipe Support — Copies existing pipe supports.

Copy Piping — Creates graphics by copying existing components in the model.

Copy and Mirror Piping — Creates graphics by copying and mirroring existing

components.

Copy and Rotate Piping — Creates graphics by copying and rotating existing

components.

Construct — Places non-intelligent graphics in the model for use as construction aids.
