What is not an advantage of using CAD over traditional methods

• Quality of drawings

• Ease of alteration

• Ease of learning to use

A section through a building component on a drawing is shown by

• Hatched lines

• A graphic symbol

• An end grain symbol

• A line terminated by small attached triangles

Depth Dimensions are important on a foundation drawing to ensure

• There is enough concrete to support the structure

• The depth will overcome the soil movements

• The backfill soil is sufficient
