About Drafting Standards

When users modify the properties of an element in the Interactive Drafting workbench, the modifications are only applied to the selected element, in the current drawing. Standard files let administrators set the properties of an element so that they will be applied to all elements of the same type in a drawing, as well as in all drawings which use a given standard.

A standard file is an XML file which makes it possible to customize globally, for a CATDrawing, the appearance and behavior of drafting elements.

With standard files, administrators can:

 
  • set standard styles that will be used as default values when creating new elements, i.e.:
    • define sheet styles
    • define geometry styles
    • define annotation styles
    • define dimension styles
    • define dress-up and dress-up symbols styles
    • define callout styles
 

Once defined, a format is applied to elements as a property.

The format of the standard file has been changed from V5 R9 onwards. If you were using a customized CATDrwStandard file on a previous release (up to V5 R8), you need to upgrade the standard file to the new XML format.

Management of Drafting Standards

Standalone Drawings

When users create a CATDrawing document (File> New), they specify the standard that will be associated with this document. The values of the parameters in the specified standard file are then copied into the CATDrawing document. Each drawing contains a copy of the standard and is therefore standalone. This makes it possible for users, projects, or companies to exchange CATDrawing documents without needing to send the standard file along.

Administrator-Controlled Access and Modification

The administrator defines and controls 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 and Functional Tolerancing and Annotation workbenches. These files are located in install_root/resources/standard/drafting.

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

Functional Tolerancing and Annotation

Standards are based on the Drafting standards and are suffixed with _3D.  In these specific standards, the colors, for example, have been customized for optimized display.

   
 
The standards suffixed with _DS (for Drafting) or with _3D_DS (for Functional Tolerancing and Annotation) are based on Drafting standards and are specifically intended to define the DS ISO 1 as the default font for all annotations styles and engineering symbols. DS ISO1 is a font based on the ISO 3098 standard defining text representation, that has been specifically customized to represent annotations.


Administrators can add as many standard files as needed. Refer to Administering Standards for more information.

Editing 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 customize the parameters included in the standard files. For information on how to customize these parameters, refer to Setting Standard Parameters.

The interactive editor is available in Tools> Standards. (It is the same editor with which you can customize generative view styles). For more information on how to use this editor, refer to the Customizing Standards chapter in the Infrastructure User's Guide.

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

Switching to Another Standard

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

Updating the Standard of a Drawing

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. Refer to Updating the Standard of a Drawing.
