Standard Command Tools

Command Tool is a generic term covering command arguments (or atoms) and command parts. Both classes of command tool fit into ordinary commands and provide different ways of stating a particular requirement. Command tools may be AVEVA E3D Design-wide or module-specific. This section describes the standard Command Tools that may be used in Paragon, Specon or Propcon. They may be one of the following:

• Standard Command Tools
  which fit into ordinary commands

• External Macro Facilities
  which can be used in a stored macro file and which control the behaviour of the macro when it is executed

• Standard Concepts
  which apply globally within Paragon, Specon or Propcon

Some of the main command tools (or the Paragon, Specon or Propcon variations of them) summarized for convenience:

Command Arguments

Command arguments are also called atoms because they cannot be broken down any further. They are individual units which Paragon, Specon or Propcon can recognize as constituents of a complete command. They usually need to be separated by spaces so that they are individually distinguishable. Command arguments are distinguished from the other command parts by being written in lower case italics. The principal command arguments are:

Note:
There must be a space before and after each of these command arguments.

Command Parts

Command parts are subsets of the general command syntax which are used frequently within other command sequences. The following command parts are summarised here:

Expressions

Any mathematical, logical or alphabetical expression whose result replaces it in the command syntax.

Dimensions

A physical dimension entered using default or explicit distance units.

Catalog Element Types

A word used to represent a specific type of element in the Catalog database hierarchy.

Element Identifiers

Methods for specifying which database element you want your next commend to act upon.

Cursor-picking Identifier (<sgid>)

This command part defines the most general method of identifying an Element. The command is completed by picking an element using the cursor in a graphical view.

Expressions (<eval>)

If a value given within a command needs to be calculated from other known values, you can enter an expression from which the required result is to be evaluated by Paragon, Specon or Propcon as it executes the command. Such an expression must be enclosed between parentheses (...) to identify where it begins and ends.

Full details of the expression syntax are given in Software Customization Overview and Software Customization Reference.

Dimensions (<uval>)

Once the working units have been specified, all dimensions input subsequently will be assumed to be in those units unless you override them. (Note that these are simply specific examples of the use of ‘real’ expressions. You can include explicit units of measurement when entering a value in any expression.)

Examples

Note:
On output, values are rounded by default as follows:

• millimetres to the nearest millimetre

• inches to the nearest 1/32 or 0.1 inch.

• However, rounding on output may be controlled by using the PRECISION command. Within Paragon, Specon or Propcon, values are stored as accurately as the host computer will allow.

Catalog Element Types (<snoun>)

This command part refers to an element type in the Catalog hierarchy.

Catalog administrative elements:

Piping Components:

Profile Components:

Joint Components:

Fitting Components:

FITTing number is not a valid option)

Dataset elements:

Detailing Text elements:

Material Text elements:

Bolt Table elements:

Connection Table elements:

Specific Element Identifier (<gid>)

This command part identifies a specific element either explicitly or by reference to its relative position in the database hierarchy.

Examples

Cursor-picking Identifier (<sgid>)

This command part defines the most general method of identifying an Element. The command is completed by picking an element using the cursor in a graphical view.
