Q

1:50 = __/__=1’-0”

A

1/4” = 1’-0” this is because 1/4” scale shows things represented to 1/48 of their original size (which is almost 1/50

30
Q

A plan that shows landscaping, walks, drives, and property lines is a ______

A

site plan

31
Q

how are walls in a floor plan typically shown? ( 2 ways)

A

either two lines or poched

32
Q

A ____ is an orthographic view of an object as seen from directly above

A

plan

33
Q

A _____ is an orthographic view of the ceiling of a room or building as though there were a mirror on the floor and a viewer could see through the roof to the ceiling’s reflection

A

reflected ceiling plan

34
Q

Floor plans should show all _____ even if they are above the 5’ cut plan

A

openings

35
Q

should doors show in an RCP?

A

no - only things that directly touch the ceiling should be shown

36
Q

A _____ is an orthographic view of the side of an object

A

elevation

37
Q

what do elevations show?

A

vertical dimensionstypes and extents of materials and finishes in a room that cannot be adequately described on other drawingshorizontal dimensions can be shown if there’s not adequate room for them on other drawings. Ex: cabinet widths and wall panel joints

38
Q

A ____ is an orthographic view of an object after the object has been cut and one portion has been removed

A

section

39
Q

sections can go through

A

an entire building or through just the edge of a countertop detail

40
Q

sections show

A

vertical dimensions and hidden info about construction that cannot be described on plans or elevations

41
Q

most details in construction drawings are

A

sections

42
Q

A _______ is a view of an object inclined to the picture plane in such a way that the three principal axes are foreshortened

A

axonometric drawing

43
Q

Three types of axonometric drawings:

A

isometric, dimetric, and trimetric

44
Q

______ is a three-dimensional view of an object in which the object is tilted in relation to a picture plane (rather than parallel to the picture plane, as with an orthographic drawing)

A

isometric

45
Q

the three principal axes in this type of drawing make equal angles with the picture plan or drawing surface

A

isometric

46
Q

how to draw an isometric?

A

tilt the floor plan 30 degrees and extend points vertically

47
Q

With a ____ drawing, one of the other two types of axonometric drawings, two of the principal axes are equally foreshortened.

A

dimetric

48
Q

With a ____ drawing, all three of the principal axes are foreshortened

A

trimetric

49
Q

A(an) _____ drawing is a three-dimensional view of an object where one plan of the object is parallel to the picture plan while the third axis is oblique to the picture plane.This type of drawing show one plane of an object (two dimensions) in true shape and scale, with the third dimension indicated by lines at a fixes angle to the true plane

A

oblique drawing

50
Q

advantage of an oblique drawing?

A

an existing orthographic floor plan can be used as the starting point without any redrawing . the plan is simply tilted at any desired angle

51
Q

why are perspective drawings the most accurate two-dimensional representation of the three-dimensional world?

A

because of convergence (apparent diminishing size of objects as they get farther from the eye)

52
Q

apparent diminishing size of objects as they get farther from the eye

A

convergence

53
Q

what is the spot is in the distance where lines in a perspective converge?

A

vanishing point

54
Q

in perspective drawing, what explains why a set of parallel lines will appear to be nonparallel and point to a vanishing point?

A

convergence

55
Q

when the point of view is perpendicular to one of the planes of the object

A

one-point perspective

56
Q

when the point of view is at normal eye level and is not perpendicular to any plane of the object

A

two-point perspective

57
Q

horizontal line drawn on the back edge of angled plan to set up a two-point perspective. this is the imaginary vertical plane onto which all points of the object are projected to create this two-dimensional image. in plan view, this appears as a cdff

A

picture plane

58
Q

two lines extend from the _______ to the left and right (in diagonals) parallel to the two major sets of parallel lines of the object.

A

Station point

59
Q

The _____ represents the place where the earth meets the sky, just as in the real three-dimensional world. It becomes the basis of the perspective view

A

horizon line

60
Q

The ____ are the points where the horizon line intersects the two vertical lines projected from above

A

VPL or VPR| Vanishing Point Left or Vanishing Point Right

61
Q

Where the line of the picture plane touches the plan drawing, a vertical line is projected down to intersect the horizon line. This becomes the _____

A

true high line (or height line)

62
Q

This is the only line on the perspective drawing where vertical dimensions can be directly scaled

A

height line

63
Q

what is used to save time in drawing perspectives

A

a perspective grid

64
Q

Two types of physical models that you can make

A

presentation models and study models (or working models)

65
Q

How does a mock-up come to be?

A

It is normally called for in the construction specs and is paid for by the client. If the client accepts the mock-up, it can be used in the final work

66
Q

Programming reports

A

need final sign-off

67
Q

What gets presented in a presentation at the end of DD?

A
  • exact dimensions of the floor plan are set- specific products and materials have been selected,- furniture selection is finalized- for most products, exact colors and finishes have been determined
68
Q

DD presentation is the last time for what?

A

the client to make changes without adversely affecting the project’s cost and schedule

69
Q

is a sample board or rendering preferred when communicating materials and finishes?

A

sample board- only a real sample can convey the accurate color, texture, and look of a finish

70
Q

Furniture can be presented how?

A

images of the furniture with an sample of the fabric next to it

71
Q

when presenting materials and furnishings, what’s good backup to have?

A

manufacturer’s product data sheets assembled on boards or in a separate notebook
