Proper Illustration of Shower Enclosures
Using the Correct Symbols and Line Values Based on the Imaginary Line Theory
When illustrating a shower enclosure from jobsite
measurements, it is important that you correctly
identify all the pertinent information on your
drawing. This includes using the proper, symbols
and line values, so that when you get back to the
shop there will be no questions on the units
measurements, in ’s or out’s, angles, etc. First of
all, the enclosure should be illustrated using
center- line measurements. Areas that don’t have
given surfaces such as the wall, curb, ceiling, knee
wall, bench seat or raised return curb will be
illustrated with what is referred to as Imaginary
Lines. Imaginary Lines are vertical, horizontal,
angled, arched or circular reference lines that do
not exist and are floating in space. Examples: The
top of the glass or header, if the glass does not go
to the ceiling; The intersecting vertical lines where
the front panel and 90° return panel meet; Where
the fixed panels of a neo-angled 135° unit meet the
door; To show the door width and location on an
inline installation; To show the height of the door if
it does not go to the ceiling; The bottom location of
a transom.

Proper Line Values and Symbols
1. - Heavy Solid Line is used to show the outer size of the unit, including in’ s or out’s and any imaginary vertical
or horizontal lines
2. - Short Dashed Line is used to show plumb and level lines when you have a unit that has out of square
conditions. The short dashed line should start at the shortest point of the panel and run plumb or level to the
longest point of the panel. The outage should be dimensioned._ _ _ _ _
3. - Long Line, Short Dash, Long Line is used to show the center-line of a hole diameter, or cutout, on elevation
views (front view), and the center-line of a curb or glass line on plan views (top view).
4. - Long Dashed Line is used to represent miter edge. ___ ___ ___ ___ ___
5. - Medium Solid Line is used for dimensional lines and measurement lines with arrowheads. ______
6. - Right Angle Symbol is used to designate square corners in an out of square condition.
7. - Joint Description uses verbiage to designate the type of joint required. Example: 45° miter joint, 22-1/2° miter
joint, overlap joint (specify which panel overlaps the other).
8. - Temperers logo or “Bug” location.
