Architecture Chapter 10 Homework The ASME-Inch and ASME-Metric drafting templates follow

Chapter 6 Lines and Lettering : Problems 6.1 through 6.11.

Chapter 7 Drafting Geometry: Problems 7.21 through 7.43.

Chapter 8 Multiviews: Problems 8.58 through 8.89.

Chapter 9 Auxiliary Views: Problems 9.15 through 9.37.

Instructions

1. From the selected sketch, determine which view should be

the front view. Then determine which other views, if any,

you need to draw to fully display the part in a multiview

drawing. Use an auxiliary view or views if needed to fully

describe the part.

2. Make a multiview sketch of the selected problem as close to

correct proportions as possible. Be sure to indicate where

you intend to place the dimension lines, extension lines, ar–

rowheads, and hidden features to help you determine the

spacing for your final drawing.

3. Using the sketch you have just developed as a guide, make

an original multiview drawing on an adequate size drawing

sheet and at an appropriate scale. Include all dimensions

needed using unidirectional dimensioning. From the se-

lected problems, determine which views and dimensions

should be used to completely detail the part.

4. Include the following general notes at the lower-left corner

of the sheet .5 in. each way from the corner border lines:

NOTES:

1. DIMENSIONING AND TOLERANCING PER ASME Y14.5-2009.

2. REMOVE ALL BURRS AND SHARP EDGES.

Additional general notes may be required, depending on the

specifications of each individual assignment. Use the following

tolerances for unspecified inch values. A tolerance block is rec-

ommended as described in Chapter2.

XXX 6.005

ANGULAR 6309

FINISH 125 µin.

For metric drawings, provide a general note that states:

TOLERANCES FOR UNSPECIFIED DIMENSIONS COMPLY

WITH ISO 2768-m. Provide a general note that states: SURFACE

FINISH 3.2 µm UNLESS OTHERWISE SPECIFIED.

Each problem assignment is given as an engineer’s layout

to help simulate actual drafting conditions. Initial problems

provide a suggested layout and problems become more complex

as you continue.

Dimensions and views on engineers’ layouts may not be

placed in accordance with acceptable standards. You need to

carefully review the chapter material when preparing the layout

sketch. In some problems, the engineer’s layout certain informa-

tion, such as the symmetry of a part or the alignment of holes.

You need to place enough dimensions or draw lines between

features to dimension the part.

To access CADD template files with predefined drafting

settings, go to the Student Companion Website, select

Student Downloads, Drafting Templates, and then

select the appropriate template file. Use the templates

to create new designs, as a resource for drawing and

model content, or for inspiration when developing your

own templates. The ASME-Inch and ASME-Metric

drafting templates follow ASME, ISO, and related

mechanical drafting standards. Drawing templates

include standard sheet sizes and formats, and a variety

of appropriate drawing settings and content. You can also

use a utility such as the AutoCAD DesignCenter to add

content from the drawing templates to your own

drawings and templates. Consult with your instructor to

determine which template drawing and drawing content

to use.
