- Acquire mode
-
The mode in which a property acquires its value from another source (properties for a project, drawing, or class).
See also Override mode and Initialization only.
- Acquisition
-
A property type that acquires its value from another source such as project properties, drawing properties, or class properties.
- Annotation
-
An AutoCAD object comprised of text and (optional) shapes. In AutoCAD Plant 3D toolset, annotations are used to display data values of P&ID components (including equipment, valves, lines, and so on). These values are displayed as text.
- Assembly
-
A group of connected components that are commonly placed in a drawing at the same time. For example, a level gauge assembly might contain an instrument and five valves. You can place an assembly from a tool palette instead of selecting each component individually.
- Assumed nozzle
-
A type of nozzle that is automatically added as a record in the Data Manager when a pipe line is connected to a piece of equipment. Unlike other nozzle types, an assumed nozzle is not visible in the drawing.
- Autodesk Connection Point (ACP)
-
An object that contains port information which allows piping connections to objects created in other programs (for example: AutoCAD MEP toolset).
- Automatic annotation
-
A type of annotation that gets automatically inserted when a component is created. See also Annotation and Linked Annotation.
- Bill of materials (BOM)
-
List of components needed to fabricate a pipeline.
- Class
-
The type of an object. Especially a Plant 3D or P&ID class such as Pipe, Valve, Nozzle, or Equipment.
- Class property
-
A property of a class; it reflects a data value. For example, the HandValve class type may have attributes of size, spec, and manufacturer. The Pumps class type may have flow, TDH, and manufacturer.
- Component class
-
See Class.
- Connection symbol
-
The graphical element in a drawing that indicates an off-page or on-page line connection. You can choose from several symbols.
- Convert
-
To change an AutoCAD object to an AutoCAD Plant 3D toolset component or line; the converted item is included in data reports.
- Converted support
-
A pipe support that was created by converting one or more AutoCAD objects.
- Data Manager
-
An enhanced secondary window in AutoCAD Plant 3D toolset; it displays data in a table.
- DWF (P&ID)
-
A Design Web Format file; it is a compressed file format created from DWG files in a project. DWF files are easy to publish and view on the Web.
- Equipment InfoTag
-
An annotation style. A multiline set of attributes that displays selected data values for a placed piece of equipment. One Equipment InfoTag for each equipment component is typically placed at the top of a drawing or in a grid across the bottom of the drawing.
- Flag
-
A symbol, like an arrow, that indicates the direction of the flow. The flag symbol contains the line number annotation. It is on the Non-engineering tab of the P&ID DIN tool palette.
- Flip grip
-
A grip that flips an object in the direction shown in the grip arrow.
- Flow arrow
-
The direction in which a schematic line flows. You can control the direction of the flow arrow using dynamic grips.
- Freestanding annotation
-
Text that is associated with a component; it does not move when the component moves. However, the data associated with the annotation updates with the component. Just the text gets disconnected. Annotations are either freestanding or linked. See also Linked Annotation.
- Gap crossing
-
A visual indication on a drawing that a line breaks on either side of a crossing.
- Initialization only
-
A property setting that limits property acquisition to a one-time event, when a component is first initialized. If the property is set to initialization only, it acquires its value from its designated source and changes immediately to override mode.
See also Acquisition and Override mode.
- Inline component
-
A component with an alignment grip that can be dropped onto a line.
- Instrument
-
A device or combination of devices used directly or indirectly to measure, display, or control a variable.
- Isometric
-
A 2D drawing that represents 3D objects. A piping isometric is a pictorial representation of a single run of pipe and can contain component and dimension detail.
See also Spool drawing.
- KKS (Kraftwerk-Kennzeichensystem)
-
A power plant classification system managed and developed by VGP Working Panel. KKS is usually used with the DIN 2481 standard.
- Line designation table (LDT)
-
List of pipe lines and their properties.
- Linked annotation
-
Graphic, text, or text with a graphic that labels a component. The text values reflect the data attribute values of a component. Examples of linked annotations are a line ID, a valve size, instrument function symbol, or Equipment InfoTag. Linked annotation moves when the component moves.
- Loop crossing
-
A visual indication on a drawing that a line loops over another line.
- Off-page connector
-
The graphical representation on a P&ID drawing of the continuance of a line from one project drawing to another.
- OrthoCube
-
A semi-transparent green 3D solid box that you use to define the boundaries of an orthographic view.
- Orthogonal connection
-
The default AutoCAD Plant 3D toolset schematic line behavior of connecting at 90-degree increments.
- Override mode
-
A mode in which an acquired property can be modified. A property that is set up to acquire its value from another source is switched from acquiring mode to override mode in the Properties palette or in the Data Manager.
See also Acquire mode. - Part
-
A piping component. Especially as it is represented in a piping spec or catalog.
- Partial Workspace
-
In vault projects, a local workspace where some project files are not in the local workspace.
- Pins
-
Symbols that identify a change in a pipe line property. In the KKS tagging standard, pins identify a change in properties (for example, Unit Number or System Code). A pin is either open (no-fill) or closed (black fill). Open pins mark the boundaries of a group with a common property. Closed pins identify a break in piping sub-systems or branches in a pipe line. When using either open or closed pins, drafters must manually change the properties of the lines beyond the open-pin boundary. Pins are located on the Non-engineering tab of the DIN tool palette.
- Pipe
-
A tube or hollow cylinder for the conveyance of fluid.
- Pipe support
-
A manufactured component that connects a pipe to a structure.
- Piping component file (PCF)
-
A file created from the 3D model that contains pipe line detail commonly used to produce an Isometric drawing and bill of material.
- Schematic line
-
A line in AutoCAD Plant 3D toolset that represents pipe lines and signal lines.
- Spool Drawing
-
A drawing that represents a fabricated sub-assembly of a pipe line.
See also Isometric.
- Tag
-
A property that uniquely identifies a component.
- Validate
-
To check a drawing or a project for errors and inconsistencies such as unconnected components, non-terminating lines, and so on.
