Views, ContinuedDrawingThere are several basic rules to drawing section linings that have asection linesprofessional finished appearance.To draw professional looking section linings. follow these rules:Section lining is always bound by visible lines.Do not overdraw section lines beyond visible lines.Visible lines never pass through an area of section lining.Section lines should be thinner than visible lines.Section lines should be uniformly thin, even in weight and with goodresolution.Section lines within a sectioned area must be parallel.Uniformly space lines in section linings.Space section lines between 1/16- to 1/8-inch apart depending on the sizeof the drawing. For average section linings, space the section linesapproximately 3/32-inch apart.Always draw section lines at 45 degrees to the horizontal.If section lines drawn appropriately at a 45-degree angle are or appearnearly parallel or perpendicular to a prominent visible outline, change theangle of the section lining to another easily drawn angle such as 30 or 45degrees.Avoid dimensioning on sectioned areas and over section linings. Whenthis is unavoidable, remove the section lining in the areas where thedimensions appear.When two or more parts in a section are adjacent, use section linings inopposing directions.You may limit drawing section lines to areas adjacent to the outline ofsectioned areas, called outline sectioning, providing the drawing remainsclear.Figure 3-64 shows examples of correct and incorrect section lining.Figure 3-64.—Correct and incorrect section linings.3-68
