About Standards

Standalone Representation

When a representation is created, the standard that is associated with it is specified. The values of the parameters in the specified standard file are then copied into the representation. Each drawing or layout representation contains a copy of the standard and is therefore stand-alone. This makes it possible for users, projects, or companies to exchange representations without needing to send the standard file along.

Administrator-Controlled Access and Modification

The Working with Standards and Generative View Styles the location of the standard files as well as the ability to define new standards, or to modify existing standards. For example, the administrator can define a single standard, and prevent users from modifying it.

Several Standard Files Available by Default

By default, several standard files are provided. Some are specifically intended for Drafting, and some for the 2D Layout for 3D Design, 3D Tolerancing & Annotation, and Generative Functional Tolerancingapps. These files are located in install_root/resources/standard/drafting.

The table below lists the standard files available by default, along with the app they are intended for.

Standards	Intended app	Remark
ISO.xml ANSI_ASME.xml JIS.xml	Drafting 2D Layout for 3D Design 3D Tolerancing & Annotation and Generative Functional Tolerancing	Standards based on the Drafting standards in which the colors, for example, have been configured for optimized display in 3D.

Important: The standards are specifically intended to define DS ISO 1 as the default font for all annotations styles and engineering symbols. DS ISO 1 is an Open Type font based on the ISO 3098 standard defining text representation, that has been specifically configured to represent annotations.

Administrators can add as many standard files as required. See Working with Standards and Generative View Styles for more information.

Edition of the Standard File

The standard files can be edited using an interactive editor. This editor provides an easy-to-use graphic interface to let administrators configure the parameters included in the standard files. For information on how to configure these parameters, see Setting Standard Parameters and Setting Styles.

The interactive editor is available in Me > Preferences > Standards. (It is the same editor with which you can configure generative view styles). For more information about how to use this editor, see Working with Standards and Generative View Styles.

Important: When creating, modifying, or configuring the XML standard files, make sure you use a CNEXT tool, for example the Standards Editor available in Me > Preferences > Standards. Using other editors (such as text editors) may alter the consistency of the standard file, and may make the standards XML files unusable.

Switch to Another Standard

When several standards are defined, users can switch a drawing to another standard. See Switching to Another Standard.

Update of a Drawing's Standard

When a standard file is modified, users need to explicitly update the drawings, which use this standard. Note that only standard parameters are affected by this update, not styles. See Updating the Standard of a Drawing.

Availability of Standard Switch and Update

Using the options available in Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > Drafting > Administration, administrators can prevent or let you to:

• Switch a drawing to another standard (from the Tools section of the action bar, click Page Layout),
• Update the standard used by a drawing (from the Tools section of the action bar, click Page Layout).

Moreover, administrators can lock these options so that other users running a session with the same environment inherit those options and cannot change them. For more information, see Installation and Configuration User's Guide: Configuring Settings: Locking Settings.
