Describe pictorial dimensioning rules.
What will be an ideal response?
Essentially, the same basic rules for dimensioning a pictorial sketch are followed as for a multiview drawing. The basic pictorial dimensioning rules apply to both the aligned and unidirectional dimensioning systems.
STEP 1 Dimension and extension lines are drawn parallel to the pictorial planes.
STEP 2 Dimensions are placed on visible features whenever possible.
STEP 3 Arrowheads lie in the same plane as extension and dimension lines.
STEP 4 Notes and dimensions are lettered parallel with the horizontal plane.
Because a pictorial drawing is a one-view drawing, it is not always possible to avoid dimensioning on the object, across dimension lines, or on hidden surfaces. Effort should be made to avoid these practices. This will prevent errors in reading dimensions or interpreting particular features of the part(s).
