Building Information Modelling (BIM) is the very latest digital process used to create Architectural drawings. Unlike 2D CAD (Computer Aided Design), BIM is a type of software far more advanced in terms of using computer modelling that holds vast amount of information and content about any construction project, no matter the size.
Using BIM you are not drawings lines. You are not even really modelling shapes. You are actually creating and inserting 3D models of physical objects in a digital real world environment right down to the north point and location on earth with sun path. Items such as walls, doors, roofs, slabs, tiles etc. Each object has the correct size and holds what information you want. For example, a 3D door can hold information telling you the size of the frame, material, thickness of door leaf, even ironmongery if you desire. The software can also calculate quantities of objects there are in the project and areas of materials can easily be extracted from the project for pricing. Moreover, BIM can create plans, sections, elevations and all the usual architectural drawings you require to the highest standard.
With AR (Argumented Reality) and VR (Virtual Reality) becoming more advanced and readily available, the future of taking BIM into AR where you can put your miniature project, like your house on your kitchen table and move around and see everything from the living room, to the kitchen sink is an exciting way forward for architects and we will shortly be here.
