Essentials of Intelligent 3D modelling
High quality single discipline models
Model requirements and intents understood
BIM/Object Modelling packages used?
Basic surface/solid modelling methods?
Precise geometric sizes and locations for all
objects
Objects fully populated with appropriate
properties and attributes
Information embedded or linked in appropriate
and consistent manner
Collaboration & Coordination
![Page 6: BIM Fundamentals - Unit 4](https://reader036.vdocuments.pub/reader036/viewer/2022081721/5540817c4a795958148b4a43/html5/thumbnails/6.jpg)

Benefits of Intelligent 3D modelling
Traditional views/drawings/documents can, if
required, be automatically extracted and internally
consistent
2D plan, sections,elevations, details
automated schedules, quantities & e-
specifications
4D construction scheduling
3D visualisations of complex areas &
perspectives. Sun studies and animations.
Extracts of quantities, areas, volumes etc.
Collaboration & Coordination

Purposes of digital exchange
3D geometry used for clash detection for Design
Phase
Creation of Project Life Cycle BIM Model
For construction/fabrication for limited trades only
for coordination and clash detection
For analysis or simulation of building performance
Collaboration & Coordination
![Page 8: BIM Fundamentals - Unit 4](https://reader036.vdocuments.pub/reader036/viewer/2022081721/5540817c4a795958148b4a43/html5/thumbnails/8.jpg)

Graphic/Visual coordination
Dimensional coordination
basis for 3D geometry use and set-out:
ACCURACY is CRITICAL!
Analysis
LCA, environmental or estimating analysis
software use.
Orientation and detail of model elements is critical
(e.g. sun studies, lighting analysis with correct
information included)
Model merging for checking/clash detection
Collaboration & Coordination
![Page 9: BIM Fundamentals - Unit 4](https://reader036.vdocuments.pub/reader036/viewer/2022081721/5540817c4a795958148b4a43/html5/thumbnails/9.jpg)

The common BIM model file data is shared by
two or more project participants in an iterative
collaborative process.
Much effort is required to:
Establish compatible file formats and workflow
Manage versions
Organize object selection
Manage orientation of models
Feedback the information
Collaboration & Coordination
![Page 10: BIM Fundamentals - Unit 4](https://reader036.vdocuments.pub/reader036/viewer/2022081721/5540817c4a795958148b4a43/html5/thumbnails/10.jpg)

One-way collaboration
BIM model file is exported to other participants for
visualisation, communication, assessment,
analysis, simulation or discipline design.
Marginally useful
Doesn‟t allow for feed back loop!
Design is ITERATIVE!

Links between applications
ODBC, COM, GDL or MDL
Geometry formats
DWG, DXF, RVT, DGN, SKP, 3DM, etc.
Intelligence is usually lost in this type of translation
Open exchange / interoperability formats
IFC or CIS/2.
Intelligence is retained in this type of translation
(hopefully!)
XML-based, DATA exchange formats
gbXML, OGC and IFCXML
Digital File Formats
![Page 14: BIM Fundamentals - Unit 4](https://reader036.vdocuments.pub/reader036/viewer/2022081721/5540817c4a795958148b4a43/html5/thumbnails/14.jpg)
Interoperability
Understanding the different file formats is
essential in managing data flow between
disciplines, users and software platforms
This is key to unlocking true collaboration
between disciplines and teams
RARELY is everyone working on the same
platform!

BIM Software tools
What‟s the point?
As a project continues, the software used
becomes more robust and complex
No project can use a single software platform
All programs have their strengths and
weaknesses
Master 2 platforms that are most important for
your industry or interests
Be aware of the rest!
