8.0 Annex D—Quality control of Computer Aided Design and Drafting data

The following table describes the items that are checked during the Computer Aided Design and Drafting (CADD) data file quality control. The first column indicates the article of the Public Services and Procurement Canada (PSPC) National CADD Standard that refers to the items. The second column describes the items checked. The last three columns are used to mark the compliance of the element as yes, no or not applicable.

3.3.3	The blocks are created respecting the rules described in the PSPC National CADD Standard (i.e., created on layer “0”, colour and linetype “ByBlock” or “ByLayer”, appropriate scale and dimension, etc.)
3.3	Blocks are not exploded

Text styles

Article	Description	Compliance
		Yes	No	n/a

Linetypes and hatch patterns

Article	Description	Compliance
		Yes	No	n/a
3.6	Only standard AutoCAD® and/or PSPC linetypes / hatch patterns are used
3.6	Linetypes and hatch patterns are metric

External references and raster images

Article	Description	Compliance
		Yes	No	n/a
2.3.3	Drawings do not contain any external reference (except if certain conditions are met and are inserted with path type set to “No Path”)

Drawing set up and page layout

Article	Description	Compliance
		Yes	No	n/a
3.7.1	The appropriate PSPC regional title blocks are inserted in the layouts at coordinates (0,0,0) with scale factor of 1 and rotation angle of 0
3.7.1	Only one title block is inserted per layout
3.7.1	Title blocks are not exploded
3.7.2	Title blocks contain all the required information
3.1	Viewports are set to the preferred scale and locked
3.7.3	Each plan, section, detail, elevation, etc., is accompanied by a heading, the appropriate graphic scale and, if required, a north arrow
3.7	Annotations objects such as notes, dimensions, hatch patterns, linetypes, blocks, etc., are scaled accordingly to match final viewport or block insertion scaling

System of measurement and coordinate system

Article	Description	Compliance
		Yes	No	n/a
3.8	Drawings are modeled at full-size using metric units in the model space. Buildings/structures plans and details are in millimetres. Site plans are in metres
2.3.1	The coordinate systems integrity is maintained for 2D drawings

Drawing presentation

Article	Description	Compliance
