This research studies automatic index system for managing
construction documents. A drawing is usually part of the
contents of an output ready sheet of A drawing can be a plan, an
elevation, or a section.The relationbetween a drawing labeled
details could be one-to-one o one-to-many .A detailcan be
referred by labels many drawings , therefore, therelation
betweena group of drawings and details can one-to-one ,one-to-
many , many-to-one,or as complicate as many-to-many.Drawing
docum-ents used to be preparedby artificially composing a
drawing labeled de-tails in the same or separatesheets of paper.
Normally,the number drawing may reach hundreds or thousands,when
a design project has very contents or is in a large scale.
Therelationship between a drawing and related may cross many
sheets.Thecross-reference of design information becomes
complicate to manage.The indexedrelationship between a drawing
and its details is often changed due to modification occurred
to drawing location, design contents, or index numbers. only
index number is usually mis-referred,but also some of
requiredcorrections can easily neglected. The reference problem
becomes particularly obvious when the of drawing sheets
increases dramatically.The problem usedto be solved by more
experienced manpower reviewing drawings to ensure accuracy.The
process is inefficient.The inefficiently process normally leaves
neglectedconflicts to be solved on site.Although researches have
been conducted ondesign and construction index system that
handles cross-relationship amongdrawing contents is very for
correctly managing drawings and their relateddetails.Auto-index
system establishes the inter-relationship between a rawingAnd
based on defined regions . The system is made by four parts :
labelingsystem , coordinate system , index-referring system ,
and library-retrievingsystem. 1) Drawing coordinate system:The
system divides drawing sheet into numbered starting from left to
right and top to bottom . Each grid can be further divided
numbered alphabetically.When a drawing is made ,the
coordinatesystem will designate the drawing with an index number
after comparing drawnarea with superimposed grids.Since no two
drawingare allowed to be overlapped,each index is identical.2)
Labeling system:The system is conducted bycircling a detail's
location drawing.The label , which is a vertically dividedcircle
, moves coincidentally its drawing changes location. The circle-
shaped label is used to store a detail's.3) Index-referring
system: The system linksa circled region inside a drawing to
detail's index number and location. Thesystem consists of a
function that change is made : all influenced indexeswill be
sorted whenever a detail is drawn drawing to its details and an
indextable that contains detail index ,drawing drawing index ,
and referred library. The system updates index number change is
made : all influenced indexeswill be sorted whenever a detail
is drawn relocated . If a detail is deleted ,alm labels in
different drawings will be automatically .4) Library-
retrievingsystem: The system increases draft efficiency when
detail are provided : details are retrieved by directly
linking circled regions to database indextable . In addition to
eliminating draft , copy , or paste frequency, drawingalso
reduced. The auto-index system is suitable to manage large
amount ofdrawing facilitate automatic referring process.
