Dr. Dejan Gavran dipl.ing. is individual developer, writing AutoLISP/ADS/ARX
applications for road and airport design since 1990. The leading product is
GCM (GAVRAN - Civil Modeller), 3D based software for the design of linear and
planar civil engineering facilities. Though primarily conceived
as a software for road and airport design, “GAVRAN – Civil Modeller” (or GCM)
has been successfully used on railway, tunneling, bridge, maritime and
landscaping projects in many countries. The first version of GCM was
completed in 1993. (while working on doctoral thesis) and became commercially
available in 1997. Since the very beginning in
1993, GCM has been fully 3D oriented software. That is to say, the working
drawings (profiles, cross sections, grading plans, mass diagrams etc.) are
generated from the 3D model. For example, profiles and cross sections are
literally cut out from 3D models – no matter how complex they are. Unlike many other software
solutions that give priority to linear facilities, GCM equally supports
modeling of planar facilities as well. GCM contains many tools that support
modeling and editing of planar facilities, especially paved and other manmade
surfaces. Curbs, conical slopes, intersecting slopes and other elements
accompanying the crossroads and other planar facilities could be modeled
easily by using GCM. GCM manipulates simple
AutoCAD entities: 3DFACEs, LINEs, ARCs, POLYLINEs, POINTs etc. 3D models are
created from the triangles that are, in fact, standard 3DFACEs. Though
created from simple entities, models produced with GCM are fully dynamic –
move a centerline and the entire model of the road changes automatically,
including the crossroads. While the full 3D approach has been the main
characteristic of GCM from its inception in 1993, 3D dynamics was introduced
as early as in 1999-2000. What is more, GCM tutorial
comes with more than 22 hours of video files accompanied with the appropriate
written explanations. The first version accompanied with the video tutorials
was GCM2000, launched in 1999-2000. GCM has been used by
companies from Serbia, Bosnia& Hercegovina, Montenegro, Switzerland,
Slovenia, Russia, Austria, Slovakia, Canada, Kuwait, Libya and some African
countries. For all these years
D.Gavran was intensively engaged on the most demanding projects,
incorporating the valuable engineering experience into the upcoming versions
of GCM. The experience to be incorporated in GCM was gathered on local road
projects in the heart of the Balkans, on motorway and hi-tech tunneling and
bridge projects in the Alpine regions of Central Europe, on the fast growing
airports of Russia and on many other projects, taking place in completely
different environments, under diverse climatological conditions, by using
different standards and guidelines and relying on completely different
construction technologies. Dr. Dejan Gavran graduated
from the Faculty of Civil Engineering - University of Belgrade - Serbia in
1986. Now acting at the rank of Docent at the same Faculty, Dejan Gavran is
giving lectures in Road Design, Airport Design, CAD In Transportation
Engineering and Urban Transportation Systems. |
