The Future of CAD with the World of BIM

November 7, 2009 in AutoCAD, CAD, Revit


As one of the fastest moving initiatives in the commercial industry, Building Information Modeling (BIM) is an innovative approach to integrating the design, construction and management of a product.

  • Recent studies revealed:
    Over 50% of architects, engineers, contractors and owners are utilizing BIM at moderate levels or higher.
  • Architects are the heaviest users of BIM with 43% using it on more than 60% of their projects (that number is expected to grow throughout 2009).
  • 77% of BIM users are involved in at least a moderate number of green projects.
  • Half of the industry is using BIM or BIM-related tools today — a 75% increase in usage over the past two years.
  • 42% of non-users believe that BIM will be highly or very highly important to the industry in five years.
  • One in five users who formally measure ROI see returns above 50%, while 9% of users who
  • formally measure ROI see returns above 100%.

BIM (Building Information Modeling) is changing the world and has also created a burden for manufacturers to supply data to the architects in a different format. This does not mean manufacturers need to forget about the simpler CAD drawings they have been supplying in the past. There will always be a need for these drawings. Actually, in the BIM format, a manufacturer should be supplying a link to their CAD file (shop drawing) as a way of providing the information part of the ‘I’ in BIM

As a manufacturer you may be asking, ‘Why do we need to provide BIM data?’ The answer is simple, the world of architecture and design is changing and it is changing fast. Right now we have two states, Wisconsin and Texas, mandating that all their government projects must be a BIM format. Many architects are stating that your product(s) will not get specified unless you provide BIM data. I will also add that a properly developed BIM model will put a manufacturer’s product specifications in front of the architect, which in turn, greatly increases the chance of getting that product specified.

However – not all projects will be in BIM. You will have some architects that will not move to the BIM format, projects that will not demand it and there are all of the existing buildings that may have expansion plans and already have documentation in CAD formats. With the understanding that BIM is a new format that is here to stay, it’s important to acknowledge the need to provide CAD drawings and shop drawings will not be going away any time soon.

3D GIS is Easy

August 4, 2009 in AutoCAD, CAD

Image courtesy of Dan Campbell, City of VancouverIf you thought 3D was hard, think again. Maybe a different point of view would help.

I recently had the pleasure of attending a seminar entitled “A New Dimension in GIS – 3D Analysis”, hosted by the British Columbia Chapter of URISA, in which a half-dozen speakers shared their 3D GIS experiences and insight during this one-day event.

Convergence: The opening keynote presentation by Doug Eberhard (Senior Director, Autodesk) set the tone of this event by providing us with an eye-popping vision of the future in which the convergence of design, geospatial analysis, simulation and visualization are fuelling the emerging business of digital cities. According to Eberhard, at the heart of digital cities are models. These models range from model agencies and model designers to model contractors and model operators. These models allow us to examine our world in new ways –ways that can help us become a model planet.

New Perspectives:
Dan Campbell (Manager, Graphics and Communications, City of Vancouver) discussed the City’s experiences, gathered over the last 20 years, in working with 3D models. In fact, it was Campbell that said, “3D is Easy; it’s 2D that’s hard.” His point was that we live in a 3D world and no-one needs to teach us how to interpret this 3D world. And yet, when we work with infrastructure designs, architectural plans and maps we force our 3D world into a 2D abstraction. According to Campbell, this 2D abstraction for the non-professional is equivalent to trying to read hieroglyphics – misinterpretation and lost meaning is often the result.

Integration: Dale Lutz (Vice President, Safe Software) explored the topic of integrating CAD, Building Information Modeling (BIM) and geospatial data and discussed the role of CityGML, Industry Foundation Classes (IFC) and LandXML in the creation of 3D models. Various integration scenarios were also presented including the use of 2D CAD buildings with LIDAR to create 3D extruded buildings and the use of 3D geo-referenced BIM.

Key Takeaway: For me, one of the key takeaways of this seminar was that 3D GIS is about making it easier for the users of the information and not the CAD and GIS gurus. It’s about an easier way to analyze, visualize and communicate information about our 3D world. The boundaries between design, visualization and geospatial analysis are blurring. And yet, it’s the people and processes and not the technology that remain obstacles in realizing the vision of 3D digital cities. Data integration and an open, non-proprietary approach continue to be at the heart of the solution.

Until next time…
