Homework
The following homework is designed to cover the course objectives for this unit.
Assignment 7.1:
Submit hand-written answers to Review Questions 14-25 given at the end of Chapter
5 on page 191 of the Architectural Drawing & Light Construction: Special Edition—
Volume I textbook.

Lab 7.1: Roof Plan and Exterior Elevations
What is the purpose?
The roof plan shows the shape of the roof to be created for the project. It also shows the
location of items such as HVAC units, exhaust fans, plumbing vents, and roof drains.
Exterior elevations are created to show what the structure looks like. In this lab exercise,
you will create orthographic projections to demonstrate the heights of doors, windows,
and other features.
In this lab exercise, you will create a roof plan of your project, printed on a D-size title
block, for critique and grading. In addition, you will create front and rear exterior
elevations of the structure being designed as the course project.
What are the steps?
• Task 1: Roof Plan
Procedure
1. Use an example, such as the one found on page 147, as a reference
when creating your own roof plan.
2. Using XREF or INSERT, place the floor plan into a new drawing as a
base to create a roof plan.
3. Freeze all layers except for the walls.
4. Trace the exterior walls by using PLINE to create a boundary for the
overhang.
5. OFFSET the PLINE to create an overhang for the building. Overhangs
typically range in depth from 12"-18".
6. Create the style of roof you desire. Remember that hips and gables
require the water to run downhill and that valleys are drawn at 45°
angles.
7. Add location of ridge vents, plumbing vents, and downspouts.
8. Print the roof plan (A4) on the D-size title block created in Unit 1 for
critique and grade.
• Task 2: Exterior Elevations
Procedure
1. Refer to pages 123-126 of the Architectural Drawing & Light
Construction: Special Edition—Volume I textbook to review how to
draw exterior elevations from the floor plan.
2. Use your floor plan to create construction lines to project locations
from the floor plan to the newly created elevation.
3. Use the Elevation Views Information Checklist on page 126 of the
Architectural Drawing & Light Construction: Special Edition—
Volume I textbook to ensure accuracy of the drawing.
4. Add foundation in hidden lines, elevation of finished floor, ceiling
locations for every level, and foundation elevation.
5. Print the elevations (A5) on the D-size title block created in Unit 1.
