CROWDED DIME SIONS.
Recommended methods include any
of the configurations shown in fig. 3.4.
Note that dots or slashes may be
substilUled when arrows are too big
for the available space.

Recommended methods include any
of the configurations shown in figs.
3.5.1.1,3.5.1.2,3.5.2 or 3.5.3.

The tenns "Ground Plan" and "Floor
Plan" are considered to be
synonymous for the purposes of these
recommendations and are equally
acceptable.

SPECIFYING SIZE OF CIRCLES.
The size of circles are nonnally
specified by their diameter. See fig.
3.5.2.
lARGE OBJECT EXCEPTION TO
STANDARD METHOD FOR
DIMENSIO ING ROUND OBJECTS.
ery large round objects such as
revolves may be dimensioned by their
radii if required for clarity or
convenience of fabrication.

nonnally specified by their radii. ee

See fig. 4.2.2.2. The shutter is
nonnally drawn standing partially
open to show how it will be hung.
Note the Slling line is a thin solid line
SlI'llJJg from the door hinge center.
The Slling line mal' extend to the limit
of travel if required.

See fig. 4.2.2.5. Tote the SlI'ing line is
a thin solid line swung from the door
hinge center. The slling line may
eXlend to the limit of travel if required.

PLATFORM BO NDARlES.
The edges of platfonns are shown by
standard lisible, i.e. thick, lines. See
fig. 4.3.1.

4.3.2

CO fFIRMING LEVEL STATUS OF
PLATFORMS.
Platfonns which are leloel are so
indicated by thin crossed lines. ee
figs. 4.3.1 and .3.3.

4.3.3

PLATFORMS OF THE SAME
HEIGHT I CONTACT.
When necessary to show platfonns of
the sanle height in contact, the
respective boundaries may be
delineated by a thin solid line. See fig.

DEFINITIOI .
"A ground or floor plan is a horizontal

section with the cutting plane passing
at whatever level (nonnally 4'·0"
above the t.1ge floor) reqUired to
produce the most descriptive view.
This cutting plane may be locally offset
as reqUired for clarity."
4.1.3

LOCATI GCENTERS OF ARCS AND
CIRCLES.
Arcs and circles are located by
crossed center lines of the form
shown in fig. 3.5.1.1., 3.5.1.2, or
3.5.3.
CENTER LINES 0 'AND OFF
ROND OBJECT.
For purposes of dimensioning, a
center line may be extended beyond
the boundaries of the circle to which it
applies in which case it becomes a
thin olid extension line. See fig.
3.5.1.2.

4.2.1

REFERENCE POINTS D PLANES.
Dimensions on Ground Plans and
Sections are to be referenced from the
st.1ge floor (or ground level), Center
[jne, and Plaster [jne. In the case of
"found spaces" or other stage types
where a clearly established Center
Une and/or Plaster [jne is not
available, all dimensions are to be
taken from easily established points or
plane(s) of reference. The points or
plane(s) of reference should be
clearly labeled and noted both on the
Ground Plan and or Section, and in
the Key.
FLAT SCENERY I GRO lD
PLANS.
S[ GLE FLAT.
A flat is shown on a stage ground plan

by a solid line of proper scale
thickness. See Art. 2.2.10.3 (Section
Views of Items Too Thin for Section
[jning). See fig. 4.2.1. Note that the
method used to generate such a line is
not a part of these recommendations.
4.2.1.1

lWO OR MORE FLATS IN
CONTACT. When it is necessary to
show how flats butt together in
assembly, the method shown in fig.
4.2.1.1 is recommended. 'ote that the
open line figure above is presented
only to show the derivation of the plan
liew representation and is not a part
of this recommendation.
