Where are dimension lines typically placed on a construction drawing?

Dimensions are placed on the floor plan. Note that the dimension lines are drafted lighter than wall lines and are generally done as a continuous group or string of numbers along a line. The extension line begins slightly away from the object (a minimum of Vi6 inch or 1.58 mm), never touching it.

Where should dimension lines be placed?

Dimensions should be given to finished surfaces or between important center lines (not to rough surfaces) wherever possible.

Where is a dimension positioned in a machine drawing?

Dimensions should be attached to the view where the shape is best shown and the features dimensioned are shown true shape. 7. Dimensioning to hidden lines should be avoided wherever possible.

What are dimension lines in construction?

The dimension line is a thin line, broken in the middle to allow the placement of the dimension value, with arrowheads at each end (see diagram below). An arrowhead is approximately 3 mm long and 1mm wide. That is, the length is roughly three times the width.

What is dimension line in engineering drawing?

The dimension line is a fine, dark, solid line with arrowheads on each end. It indicates direction and extent of a dimension. In machine sketches and drawings, in which fractions and decimals are used for dimensions, the dimension line is usually broken near the middle to provide open space for the dimension numerals.

How do you write dimensions in construction?

For example, a dimension of a rectangular room on a blueprint, 14′ 11″ X 13′ 10″ equates to a room size of 14 feet, 11-inches wide by 13 feet, 10-inches long. Dimensions are expressed as width by length by height or depth in three-dimensional space.
