Week 9

Drafting Interior Elevations and Sections

Objective

• This chapter discusses what interior elevations and sections are and how to draft them

What Is an Interior Elevation?

• Elevation is a vertical drawing of a wall• Assumes the viewer is standing up and

looking straight ahead• Created by projecting features down from

the floor plan• Vertical heights and distances from the

floor are dimensioned• Referenced from the plan with a callout

What Is an Interior Elevation? (cont’d.)

Figure 12-3 The location of the callout determines what is drawn on the elevation. Everything in front of the arrow apex is projected down. Nothing behind the arrow apex is drawn.

What Is a Section?• A cut through a building or a portion of a

building– Full, partial, and detail

• Full section is a vertical cut through the entire length or width of the building and from foundation to roof

• Parts of a full section may be encircled with a heavy, dashed line that has an attached symbol telling the reader where to look for a larger-scale drawing

What Is a Section? (cont’d.)

Figure 12-10 Transverse and longitudinal sections through a house with a gable roof.

What Is a Section? (cont’d.)

• Steps for drawing a longitudinal section– Choose where to place the cutting plane– Project the walls down– Poché the walls that are cut through– Draw the ceiling’s height at the slice

location in the floor plan

Wall Sections and Details

• Vertical slice through a wall from footing to roof

Figure 12-23 A wall section is made with a vertical cutting plane from foundation to roof.

Wall Sections and Details (cont’d.)

Figure 12-26 Wall section (brick veneer on concrete block).

Partial Section

• Vertical cut through a small portion such as one wall

• A detail is a vertical or horizontal cut made through an even smaller portion

• Show how the pieces go together• Details depend on the building’s

complexity, number of floors, and changes in the materials and methods of construction

Architectural Millwork• Items manufactured in a lumber mill

– Windows, doors, shutters, columns, pediments, and cabinets

• Millwork pieces drawn by interior designers – Case goods– Cabinets– Cabinet doors– Front doors– Interior moldings– Trim

Cabinets• Non-upholstered piece of furniture used to

store, or case, household goods• Framed cabinets have rails and stiles• Overlay is the amount of front frame

covered by the door and drawer• Reveal is the part of the front frame that is

exposed• Tambour door has its own frame and can

be used on both framed and frameless cabinets

Cabinets (cont’d.)

Figure 12-27 Framed and unframed cabinets.

Cabinets (cont’d.)• An inset door sits within the face frame

and is flush with the front edges of the cabinet box

• A lipped door has a rabbet (groove) cut all the way around the door on the back edge

• A full overlay door is the one option available for frameless cabinets

• Standard overlay door face frame has a full reveal around the door and drawer perimeters

Cabinets (cont’d.)

Figure 12-29 Different cabinet types and their sizes in elevation.

Cabinets (cont’d.)• Cabinet door style

– Slab oFlat panel or framelessoMade of one solid pieceoNo raised or recessed profile and panel

– Recessed panel oLooks like a picture frameoWood frame around the edge surrounds a

panel in the middle– Raised panel door protrudes forward

Cabinets (cont’d.)

Figure 12-34 Cornice moldings can be crown (convex), cove (concave), or a mixture to create an elegant look.

Summary• Elevations and sections are orthographic

drawings that give heights and details of features shown on the floor plan– Include everything that is hung on the wall– Details show intricate features of construction – With dimensions, they are paired with floor

plans to completely describe a design
