But when it comes to dimensioning, it doesnt know anything about tolerances and precision except what you tell it. For example, most code-related dimensions, such as minimum corridor, stair, and door widths, are to the nearest inch. These consist of elevation markers, section markers and detail markers. Blueprints are typically drawn on a -inch scale, which means every quarter-inch on the plan equals 1 foot of actual length on the completed structure. Dimensioning columns even to half an inch is probably asking for unachievable precision. No interior dimension should be longer than half the column bay that its in. First, the practical answer: A well-dimensioned plan doesnt necessarily take more time than a messily dimensioned one, and is less likely to have mistakes.
