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

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

detail to the section
drawing.
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.

Details (cont’d.)

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

Different cabinet
types and their
sizes in elevation.
Cabinets (cont’d.)
• Cabinet door style
– Slab
o Flat panel or frameless
o Made of one solid piece
o No raised or recessed profile and panel
– Recessed panel
o Looks like a picture frame
o Wood 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
