Types of Lines in Technical Drawings

Kitchen Layouts

• A single-wall kitchen layout features all cabinets, countertops, and major work services along one wall.
• A U-shaped kitchen layout allows for an excellent work triangle by placing the fridge, oven, and sink on their own side of the U.

Peninsula-Shaped Kitchen

• A peninsula layout provides ample space and storage, adding countertop space, storage, and usability.

Galley or Corridor Kitchen

• A galley kitchen features a small work triangle with working stations facing parallel walls.

L-Shaped Kitchen

• An L-shaped kitchen consists of two adjacent countertop legs forming a right triangle, with one typically longer than the other.

Island Kitchen

• An island kitchen layout places ovens, ranges, fryers, and other cooking equipment in one module at the center of the kitchen.

Line Symbols in Technical Drawing

• Visible lines are thick dark lines showing object outlines, visible edges, and surfaces.
• Construction lines are very light and thin, used to construct layout work.
• Dimension lines are thin and dark, showing object size with numeric values, often terminating with arrowheads or tick markings.
• Hidden lines are short dash lines showing non-visible surfaces.
• Center lines are long and short dash lines, indicating the center of holes, circles, and arcs.
• Extension lines are thin and dark, showing the start and end of dimensions.
• Cutting plane lines are extra thick, indicating cutaway views or planes of projection.
• Short and long break lines are short and long medium lines showing cutaway views of long sections.
• Section lines are medium lines drawn at 45 degrees, showing interior views of solid areas of the cutting plane line.
• Border lines enclose or frame the drawing, made of very thick and dark lines.
• Phantom lines are long lines followed by two short dashes, showing alternate positions of moving parts.

Kitchen Layout Importance

• A kitchen layout contributes to safety, allowing for smooth workflow and maximizing kitchen space.

Kitchen Work Areas

• Receiving area: where food and beverage products are delivered.
• Storage area: for storing, keeping, and safeguarding materials.
• Working area: where food can be prepared, cooked, and refrigerated.
• Food counter: a flat, cleanable surface for food preparation.
• Garbage area: should be located in a secure place away from kitchen food products and utensils.
