Question 1

Where is a floor plan cut to look down?

Answer 1

5’ above the floor

Question 2

What is a reflected ceiling plan (RCP)?

Answer 2

Plan showing ceiling elements as if reflected in a mirror

Question 3

What are performance specifications?

Answer 3

Describe required results without naming product.

Question 4

How would you draft an orthographic drawing (plan, elevation, section)?

Answer 4

Draw flat views using parallel lines at 90°; no depth distortion; all dimensions are true scale.

Question 5

How do you read an architect’s scale?

Answer 5

Measure fractions of a foot in the portion on the end with the subdivisions and measure full feet with the remainder of the scale

Question 6

What are some common scales used for different types of drawings?

Answer 6

• 1/16” very large floorplans
• 1/8” floor plans
• 1/4” floor plans and simple interior elevations or sections
• 3/8” complex elevations or sections
• 1/2” enlarged floorplans and very complex elevations
• 3/4” enlarged floor plans and full wall sections
• 1” simple details
• 1 1/2” ceiling details and simple cabinet details
• 3” door, cabinet, furniture, and similar details

Question 7

What scales should never be used when plotting drawings?

Answer 7

3/32” or 3/16”

Question 8

When can a graphic scale be used instead of writing out a scale on a drawing?

Answer 8

When drawings are reproduced at an odd size for presentations or publication

Question 9

What is an orthographic drawing?

Answer 9

A flat floor plan

Question 10

What is an orthographic projection?

Answer 10

A flat elevation or section view

Question 11

What scale is typically sufficient for most floorplans?

Answer 11

1/8”

Question 12

What scale is good for showing very complex construction details?

Answer 12

3”

Question 13

What is another word used for a hatch pattern?

Answer 13

Poché

Question 14

In an RCP, an opening over a 7 foot high door in a room with an 8 foot ceiling does not show. Instead, what is drawn?

Answer 14

The wall above the door is drawn continuously just as the wall touches the ceiling at that point

Question 15

Cabinet widths and spacing of wall panel joints are commonly shown on interior elevations rather than on plans, why?

Answer 15

Because elevations are drawn at suddenly larger scale, and floor plans, some horizontal dimensions can also be described if there’s not enough room on plan

Question 16

Why are section cuts invaluable drawings?

Answer 16

Not only do they show the vertical dimension, but they also show hidden information about construction that cannot be described on plan or elevation

Question 17

A section drawing shows a cut through both __ & __

Answer 17

Solids and voids

Question 18

On a section drawing, what is used as an indication for voids and solid portions?

Answer 18

Solid portions are given a hatch with standard material indications and voids are left blank

Question 19

To show the relationship between the material cut and section and adjacent construction on drawings, __ are used to indicate elements that occur beyond the section cut

Answer 19

Thin lines

Question 20

What kind of drawing is this?

Answer 20

axonometric drawing

Question 21

What type of drawing is this?

Answer 21

Trimetric

Question 22

What type of drawing is this?

Answer 22

Dimetric

Question 23

What type of drawing is this?

Answer 23

Isometric

Question 24

What type of drawing is this?

Answer 24

Dimetric

Question 25

What kind of drawings are these?

Answer 25

Oblique

Question 26

How would you draft a one-point perspective drawing?

Answer 26

Draw a horizon line, place one vanishing point, and project depth lines toward it.

Question 27

How would you draft a two-point perspective drawing?

Answer 27

Draw a horizon line with two vanishing points and project edges toward those points.

Question 28

What distinguishes perspective drawings from orthographic and axonometric drawings?

Answer 28

Perspective drawings use vanishing points and show depth realistically; they are not to true scale.

Question 29

If lines remain parallel and measurable, what type of drawing is being used?

Answer 29

Orthographic or axonometric.

Question 30

What is a picture plane in drafting?

Answer 30

The imaginary vertical plane onto which all points of the object are projected to create a two dimensional image

Question 31

What is a station point in drafting?

Answer 31

The exact position of the viewers eye in a perspective drawing

Question 32

In most perspective drawings, the horizon line is assumed to be a high-level or at about how high above the floor?

Answer 32

5 foot or 5 foot six

Question 33

To shorten the time required to produce perspective drawings pre-printed __ can be used

Answer 33

Perspective grids

Question 34

What is the typical scale used to construct a model?

Answer 34

1/4 or 1/2 inch scale

Question 35

What is the key difference between design development presentations and earlier presentations?

Answer 35

In design development, exact dimensions are finalized, specific products and furniture are selected, and finishes are determined — meaning changes at this stage can directly affect the project’s cost and schedule.

Question 36

Before proceeding with construction documentation, what should be presented to the client for approval and signature?

Answer 36

The programming document

Question 37

On a presentation board, how should items be scaled?

Answer 37

Items that are larger scaled or have more of in the room should be larger & smaller items like pillows should be small scale

Question 38

What types of tests are used to measure the moisture level of a concrete floor?

Answer 38

hygrometer test relative humidity test polyethylene sheet test

Question 39

The __ test measures alkalinity and is used in addition to the pH test to assess concrete before applying tile adhesives or coatings.

Answer 39

titration
