The Preliminary Groundplan: Basic
Drawing
The preliminary groundplan is created in three steps.
Using all available information, horizontal and ver-
tical coordinates are drawn, double-checked, and
then joined to create the scaled drawing. For clar-
ity, the illustrations will show these lines properly
spaced in the three steps to quickly create the over-
all picture.
Step 1: Draft the Rough Outlines
The left-hand side of Figure5.5 shows the horizontal
placement of the vertical lines that will be used to cre-
ate the preliminary groundplan of the Hybrid Theatre:
stage right and stage left. Draw the first vertical line
in the middle of the drafting surface and define that
as centerline, one half of groundplan zero-zero. Now
draw the left-hand column of lines or tic marks rela-
tive to centerline, on the left-hand side (stage right) of
the page. Next the second column of lines or tic marks
can be made relative to centerline, on the right-hand
(stage left) side of the page. When completed, those
vertical lines will resemble Figure5.6A.
Next, the horizontal lines will be added. The
right-hand column of Figure 5.5 lists the vertical
placement of the horizontal lines: stage right, center,
and stage left. Draw the first line and define that as
plaster line, the other half of groundplan zero-zero.
Now draw the following lines or tic marks relative to
that line (positive to the algebraic “over” or above,
negative to the algebraic “under” or below). When
completed, those added lines resemble Figure 5.6B.
Now some quick drafting and a little artistic license
will clean this up.

The result is the general shapes and outlines shown
in Figure5.6C. The basic outlines and shapes for the
groundplan are now complete.
Step 2: Fill in Information Upstage
of Plaster line
The next step is to draw the current masking posi-
tions upstage of plaster line. First, this means draft-
ing the location of each lineset relative to plaster line.
This is one moment when CAD drafting can be an
advantage; copy the lineset schedule box from the
section, and paste that into the groundplan. The box
then includes the lineset number, the distance from
plaster line, and a placeholder for the trim height and
the goods. After rotation, the box is aligned so that
