Chapter 3 Architectural Drafting Equipment

Today vs. Yesterday • Manual drafting – Term used to describe traditional pencil or ink drafting – Tools and equipment • • • Scales Template Computer Software Mouse (2 Button w/ scroll)

Deliverables • Manual drawings – Prepared on precut drafting sheets • Contain printed graphic designs for company logo and information, borders, and title blocks • Computer-aided drawings – Created using a template • Contains a border, title block, and graphic designs for the company • Stored in files and reproduced on media

Scales • Used for: – Making measurements – Establishing dimensions – Drawing features at reduced size • Scale notation: – Usually noted on title block or below the view differing in scale

Scales (cont’d. ) • Types: – Metric scale • Millimeter is commonly used – Architects scale • Contains 11 different scales – Civil engineer’s scale • Commonly used to draw site plans, maps, or subdivision plats or to read existing land documents

• Architect’s Scale - 11 different scales – – – Locate the correct scale before beginning Ten of the scales are based on the inch unit Other scale is divided into 1/16 th of an inch Be careful to watch reading direction 1/4”=1’-0” Residential 1/8”=1’-0” Commercial

• Engineer’s Scale - 6 different scales – Can be identical or different units – 1”=20’ Common for ¼ Acre or less – 1”=30’ Common for ½ Acre

• Factors to Determine Scale: – Actual size of structure – Amount of detail to be shown – Paper size selected – Amount of dimensions and notes needed – Common practices (company) • DH uses 1/8”=1’-0” because print on 11” x 17” • Ivory uses 1/4”=1’-0” because Arch C 24” x 36”
