2D CAD vs 3D BIM, two completely different working methods. Here are the true advantages of BIM together with a demonstration video.
Many professionals still use the traditional 2D CAD technology for representing their design ideas to clients. This means that they still prefer to draw countless lines, polylines and generic geometrical shapes to represent their objects (doors, windows, walls, columns, etc) in the project's working drawings, such as, floor plans, elevation views, cross-sections, etc.
This probably means that they still haven't come to grips with the enormous advantages of using BIM technology.
Thanks to a 3D BIM, architectural design is accomplished by inserting graphical objects with their own functional characteristics and properties. These kind of intelligent objects allow the designer to produce detailed working drawings and construction documents automatically. So avoiding to have to draw those incredibly complex drawings, full of lines and poly-lines by hand.
Here are the true advantages of using a BIM technology.
2D CAD vs 3D BIM: time saving
The great efficiency of using a BIM software means that the designer can concentrate more on the creativity aspects of a project without having to constantly worry about updating a multitude of line entities throughout the entire project. This translates into an incredible increase in productivity because each object, chosen from a BIM objects menu, already comes with a set of pre-defined information that can provide useful data for calculating project cost, thermal performance aspects, maintenance, structural, etc.).
All this leads to a considerable saving of time.
2D CAD vs 3D BIM: drastic reduction of Errors
Within a BIM design procedure, floor plans, elevation views and section views are simply different views of the same object. All views can be observed according to specific design phases. Whenever there's a change somewhere in the project, these changes seamlessly affect all other related documents.
As an example, by simply changing the external finish of a facade element, this causes a modification in the wall's transmittance value, its cost and even its structural load.
This allows the technician to avoid mistakes and be sure to have all drawings aligned with the latest project revisions wherever and whenever they are introduced.
CAD 2D vs 3D BIM: simplicityat its best
Thanks to the use of BIM technology, even complex models become easy to generate.
Architects can start to push their design capabilities even further proposing ideas that they wouldn't even have imagined doing using traditional 2D CAD tools.
2D CAD vs 3D BIM: Integration with other design aspects
BIM definitely expands design horizons. The 3D BIM model can in fact be enriched by a series of additional information that allow full integration with:
• structural calculation
• energy performance calculations
• construction estimating
• technical installations
• maintenance and facility management
3D BIM software
So ACCA has developed Edificius, a highly professional BIM software for architectural design with integrated structural design, energy performance, cost estimating, health and safety, maintenance and technical systems design, etc.
As a result in this video you'll be able to see how easy it was to recreate the 3D BIM model starting from a 2D CAD drawing of this modern building project in Spain (Zaragoza).
