Readme Documentation
This readme file will
give you some additional information and guide you through some
of the aspects of using MoDOT's on-line Standard Plans Book.
Drawing Formats:
Each drawing is presented
in two formats: an inactive image that can be easily viewed or
printed by use of the Acrobat Reader, and a downloadable Microstation
drawing. In most cases, each drawing has a Metric image, an English
Image, and a dual unit Microstation file. Unavailability of an
English image is due to the existence of obsolete hand-drawn English
plans that will not be converted to electronic files. In a few
cases, the Microstation drawing will be unavailable due to the
drawing being a Lotus 1-2-3 file.
Multiple Page Files:
The images of multiple
page drawings will take the form of subsequent pages of a single
Acrobat file. The downloadable version of a multiple page standard
plan will be presented in one of two ways. Recently revised multiple
page drawings will consist of individual files and download buttons
for each sheet of the drawing. Until a multiple page drawing is
revised, it will be presented as a single Microstation file showing
all pages of the drawing with plotting points for each in the
upper left and lower right corners. These formats result from
drawings being placed in "real world" units as they are revised.
Dual Unit Drawings:
As previously mentioned,
the Microstation files are in dual (Metric and English) units.
M icrostation software must be used to open and manipulate the
.dgn files. If Microstation is not available, it is recom m ended
that the Acrobat files be used instead. English units reside
on level 45 of each drawing, while the Metric units are on level
46. Additional information or geometry may also reside on various
levels. It is recommended that the user activate all levels and
then deactivate levels as needed. When all levels are activated,
the drawing will display all geometry and both sets of units simultaneously.
The appropriate levels must be deactivated in order for the desired
units to appear legibly.
