    Requirements for 2D CAD

CAD / Drawing standards

General

2D drawing information – for the purposes of assembling a printed set of plans – is derived from the BIM model(s) to the fullest extent possible. All BIM information is fully parametric so that all applicable information regarding fixtures and/or elements can be used to generate schedules. Where required by the client, editable text files are attached to fixtures/elements to aid in calculations.

In the absence of existing documented CAD/drawing standards mandated by the client, the BIM Team nominates the CAD/Drawing Standards to be used on the project. Any amendments considered necessary to these standards must be documented.

When the CAD / Drawing standards and amendments have been agreed by the BIM Team they are adopted and managed for consistent application by the BIM Manager.

At a minimum, the CAD/Drawing Standards address the following:

      • Drawing naming conventions.
      • Layer naming conventions.
      • Sheet sizes.
      • Title blocks.
      • Cross-referencing.
      • Drawing scales.
      • Linestyles and line weights.
      • Gridlines.
      • Dimensioning.
      • Typefaces.
      • Annotations and keynoting.
      • Labelling and tagging.
      • Abbreviations.
      • Symbols.
      • Representation of materials and finishes.
      • Schedules.
      • Legends.
