BIM explained in laymen’s terms
BIM is an acronym that stands for Building Information Modeling. When it comes to BIM everything starts with a 3D digital model of the building. This model, however, is way more than pure geometry and some nice textures cast over it for visualization. A true BIM model consists of the virtual equivalents of the actual building parts and pieces used to build a building. These elements have all the characteristics – both physical and logical – of their real counterparts. These intelligent elements are the digital prototype of the physical building elements such as walls, columns, windows, doors, stairs etc. that allow us to simulate the building and understand its behavior in a computer environment way before the actual construction starts.
Nevertheless with the advent of mobile technologies such as iPhones/iPads and the likes utilization of BIM has broken out from the close circle of professionals. Clients, building owners and operators are getting more and more access to BIM models through their mobile devices even without the need to installing a BIM application first. This shift will put the adoption of BIM onto the next level so you as a professional really cannot afford ignoring BIM.
Why Should I Switch From CAD to BIM?
BIM and CAD represent two fundamentally different approaches to building design and documentation. CAD (Computer Aided Design) applications imitate the traditional “paper & pencil” process in so far as two-dimensional electronic drawings are created from 2D graphic elements such as lines, hatches and text, etc. CAD drawings, similarly to traditional paper drawings, are created independently from each other so design changes need to be followed up and implemented manually on each CAD drawing. BIM (Building Information Modeling) applications imitate the real building process. Instead of creating drawings from 2D line-work, buildings are virtually modeled from real construction elements such as walls, windows, slabs and roofs, etc. This allows architects to design buildings in a similar way as they are built. Since all data is stored in the central virtual building model, design changes are automatically followed-up on individual drawings generated from the model. With this integrated model
approach, BIM not only offers significant productivity increase but also serves as the basis for better-coordinated designs and a computer model based building process. While switching from CAD to BIM is already justified by the benefits achieved during the design phase BIM offers further benefits during the construction and operation of buildings. You can find further information about CAD vs. BIM in Ralph Grabowski’s “CAD & BIM – Is there a Free Pass?” whitepaper.

OPEN BIM Program
The OPEN BIM Program is a marketing campaign initiated by GRAPHISOFT®, Tekla® and others to encourage and facilitate the globally coordinated promotion of the OPEN BIM concept throughout the AEC industry, with aligned communication and common branding
available to program participants.
OPEN BIM Certification is a technical certification system to help AEC software vendors improve, test and certify their data connections to work seamlessly with other OPEN BIM solutions.
Why is it important?
- OPEN BIM supports a transparent, open workflow, allowing project members to
participate regardless of the software tools they use.
- OPEN BIM creates a common language for widely referenced processes,
allowing industry and government to procure projects with transparent commercial engagement,
comparable service evaluation and assured data quality.
- OPEN BIM provides enduring project data for use throughout the asset life–
cycle, avoiding multiple input of the same data and consequential errors.
- Small and large (platform) software vendors can participate and compete on
system independent, ‘best of breed’ solutions.
- OPEN BIM energizes the online product supply side with more exact user
demand searches and delivers the product data directly into the BIM.

ARCHICAD / Revit
ARCHICAD Connection Add-In for Autodesk Revit
The GRAPHISOFT ARCHICAD Connection is a free Add-In for Autodesk Revit. The Add-In improves the IFC model-based and bi-directional data exchange between GRAPHISOFT® ARCHICAD® and Autodesk® Revit®.
The GRAPHISOFT ARCHICAD Connection Add-In for Autodesk Revit 2017 has three functions:
- “Improved IFC Import” imports IFC models to Revit using extra features that
improve the interpretation of architectural models;
- “Link IFC” merges IFC models into the current Revit project as a non-editable
- “Export to ARCHICAD” exports Revit model elements in IFC files that are
specially enhanced for use in GRAPHISOFT ARCHICAD.
Important: For best results, make sure you have installed the latest version (17.2.0 or later) of
Autodesk’s IFC 2017 import-export app for Revit.
For detailed information, see manual.

ARCHICAD / Rhino
Rhino – Grasshopper – ARCHICAD Toolset
Rhino – Grasshopper – ARCHICAD Toolset connects the best design tools for the different design stages on both Mac and Windows platforms. These tools fill a gap in the design process between early stage design and Building Information Modeling. They offer solutions for seamless, bi-directional geometry transfer as well as a way to translate basic geometrical shapes into full BIM elements while adding algorithmic editing functionality.
BIG and Algorithmic Design
Jakob Andreassen, BIM Manager of BIG, shares how they benefit using free-form, algorithmic design and BIM by leveraging the best that each software tool has to offer throughout the design process.
