Help with Alternative Formats

PWGSC has announced the launch of its 2011 National CADD Standard, replacing the previous 2006 version. Changes have been made to this standard primarily to:

  • Adapt the standard to new technologies and new software releases.
  • Revise thoroughly the list of layers and abbreviations to better meet the needs of the various disciplines.
  • Clarify operational requirements with respect to CADD files.

1. Project Delivery

At project start-up, PWGSC will provide the pertinent CADD base plans to be used as the foundation for new project drawings. All new work created for the project must meet the National CADD Standard irrespective of the condition of any existing files provided at the outset of work.

2. Drafting Standards

2.1 Block Standard

It is now possible to create annotative blocks that can scale themselves automatically to any given scale. However, to avoid confusion, it is strongly recommended to use only one method throughout each project drawing set: the traditional method that lets the user chooses the insertion scale, or the Annotative option that automatically manages the insertion scale.

2.2 Text Style Standard

Text styles for use in drawings must be created using Standard AutoCAD® SHX or the following TTF font files: Arial, Arial Narrow, and StylusBT.

In addition, it is now possible to create annotative text styles that can size themselves automatically to any given scale. As for blocks, it is strongly recommended to use only one method throughout each drawing set: traditional text styles or annotative text styles.

Text style usage should be uniform throughout each project drawing set and limited to a maximum of four different font files per project that are determined in collaboration with PWGSC.

2.3 Dimension Style and Multileader Style Standard

It is now possible to create annotative dimension styles and multileader styles that can size themselves automatically to any given scale. As for blocks and text styles, it is strongly recommended to use only one method throughout each drawing set: traditional dimension styles set with different overall scales to suit different printing scales, or annotative dimension styles that are set up automatically based on the drawing scale. In addition, the multileader style names are now governed by the standard in a similar format to dimension styles.

2.4 Hatch pattern Standard

Only Autodesk® and PWGSC hatch patterns are now allowed in drawings.

2.5 Layering Standard

The list of layers has been revised extensively. The major changes have:

  • Created a more logical structure that better represents building systems and facilitates the use of filters in layer names. Several groups have been added, combined, or divided in order to better meet the needs of various types of drawings.
  • Eliminated duplication in the use of abbreviations.

Overall Changes that Apply to All Disciplines

New Subdivision Added to Layer List: A new subdivision has been added to the layer list to make it possible to group together subsets of layers that represent building systems or categories of related data. Each subdivision contains a primary layer (underlined in the table in Annex A) and supplementary layers (shown in grey in the same table) that allow information to be subdivided more precisely as required. The use of supplementary layers is optional and depends on a drawing's requirements.

Simplified Equipment/Symbols Categories: The many types of equipment and the layers representing them have been simplified into two categories from the previous multiple categories. Equipment shown in actual size is now associated with an equipment layer (-EQP), and equipment that is represented by symbols and not to scale is associated with a symbols layer (-SYM). This change eliminates several abbreviations and greatly simplifies the list of layers, particularly for electrical systems and mechanical components.

Major Changes by Discipline

Varying degrees of modifications have been made to each discipline. Below is a non-exhaustive list of these changes by discipline.

Architecture: Minor changes have been made to some abbreviations and groups to eliminate duplication and improve logic in the layer structure.

Bridges and Dams Engineering: This discipline now includes information on dams that was previously part of the Marine discipline. The close relationship between bridge and dam structures makes this a logical combination and provides the rationale for this change.

Civil Engineering, Site Design, and Landscape Architecture: This discipline encompasses several very diverse categories ranging from landscape architecture to highway infrastructure. To better meet a broad range of needs, substantial changes have been made with respect to landscaping, the environment, and vegetation.

  • Site features are now divided into two separate groups, depending on whether natural or man-made components are involved.
  • A new group has been created for vegetation.
  • The layer names for storm sewers and sanitary sewers have been modified based on a more logical system that allows better handling of layers with filters.
  • The gasses and fuels group has been replaced with four new groups based on fuel type to facilitate the handling of this information.
  • Several abbreviations have been renamed to avoid duplication, improve logistics, and make it easier to use filters for layers.

Electrical Systems: This discipline saw no major changes, but several layers have been renamed to contribute to a more logical layer structure, particularly for the circuit diagrams group.

General Information: Although it is still possible to create layers for details (DT) in any discipline, detail layers are now listed as a group under the General Information discipline. In addition, the elevations (EV) and sections (ST) groups have been eliminated. Elevations and sections are now included within the details (DT) group, making it easier to handle this information.

Mechanical: The majority of the groups in this discipline have been completely revised. Instead of being divided by graphic elements (pipes, equipment, symbols, ducts), the groups now represent separate mechanical systems, such as heating and cooling, domestic water, control system, HVAC system, etc.

Interior Design: As in the case of Architecture, only a few minor changes have been made to this discipline in order to eliminate duplication.

Legal Surveys: This discipline has been completely revamped and simplified to avoid confusion with the Civil Engineering discipline and to better meet land survey information needs.

Marine: The major change to this discipline is the transfer of the dams' information to the Bridges Engineering discipline. In addition, a few new layers have been added.

Real Property Space Management: Only a few layers in this discipline have been renamed to eliminate duplication and improve the logical structure of the layers.

Structure: Only one minor change has been made to this discipline in order to comply with the logical structure of English-language abbreviations.

3. Layer Modification Tables

Table 1 - New Layer List

Note: In the following table, the new subdivisions are framed, the primary layers are underlined, and the supplementary layers are in grey. The supplementary layers allow information to be represented more precisely. However, it is also acceptable to use only the primary layer.
