Week 9

1. Week 9 Drafting Interior Elevations and Sections

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

3. 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

4. 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.

5. What Is an Interior Elevation? (cont’d.) Figure 12-6 Constructing the elevation.

6. 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

7. What Is a Section? (cont’d.) Figure 12-10 Transverse and longitudinal sections through a house with a gable roof.

8. 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

9. What Is a Section? (cont’d.) Figure 12-19 Adding detail to the section drawing.

10. 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.

11. Wall Sections and Details (cont’d.) Figure 12-26 Wall section (brick veneer on concrete block).

12. 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

13. 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

14. 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

15. Cabinets (cont’d.) Figure 12-27 Framed and unframed cabinets.

16. 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

17. Cabinets (cont’d.) Figure 12-29 Different cabinet types and their sizes in elevation.

18. Cabinets (cont’d.) • Cabinet door style • Slab • Flat panel or frameless • Made of one solid piece • No raised or recessed profile and panel • Recessed panel • Looks like a picture frame • Wood frame around the edge surrounds a panel in the middle • Raised panel door protrudes forward

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

20. 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
