3D Modeling

3D drafting is the latest in drafting know-how. It is based on the idea of BIM ' Building Knowledge Model ' in which a virtual 3D model of a building is created. Knowledge is then extracted from the model to generate building designs, 3D renderings & animation. 3D know-how is faster than 2D drafting, more correct & has lots of benefits. The benefits to drafting in 3D can be seen in the technique of generating designs, which is as follows:



Buildings are modeled using 3D digital elements such as walls, windows, doors, roofs, cabinets, appliances & any other aspect of a building. One time the model is created, any view & any amount of knowledge can be extracted from the model.
The model can be sliced horizontally to view the floor plan.
The model can be sliced vertically to view wall & building sections.
A bird's eye view of the model can be shown to generate the roof plan.
Elevations can be automatically generated from the model.
The 3D digital elements that make up the model store knowledge which can be extracted in to schedules & tables such as window & door schedules.
Materials such as brick, stucco, paint, roof tiles or any other material can be applied to the 3D digital elements of the model to generate full color 3D renderings & animation.


Classical Drafting makes use of AutoDESK products 'AutoCAD, AutoCAD Architecture (formerly called Architectural Desktop 'ADT) & Design Review

If any changes are made to any element of the building, the changes are automatically reflected in all designs, sections & schedules & in other parts of the plan set. Making changes is necessary in place, for example, adding or changing a door, & the changes are automatically reflected in every single place else in the designs ' on the floor plan, on the elevations, on the door schedule & in all other places where the door appears in the designs.
