For compositional plan projects, while there is the accentuation on utilizing 3D models and building BIM displaying, the reliable act of utilizing structural drafting and 2D specialized drawings is as yet ordinary in the AEC business. Engineering drafting has developed from the Peri phase to PC helped plan and drafting (computer aided design) programming programs. Drafting rehearses help to give engineering development drawings that incorporate the specialized subtleties of compositional, underlying and electrical components expected for the development of a structure. To comprehend the stage at which compositional drafting happens, the work process of a structure plan lifecycle should be thought of.

The fundamental work process of a building configuration project begins with the modeler making a reasonable arrangement which is normally displayed into compositional 3D models and delivered as photorealistic pictures for promoting and show to clients and clients.

When the reasonable plan is endorsed by the client, the plan is then advanced into more detail and imparted to different gatherings, for example, primary and MEP engineers. The manner by which the plan is advanced for the 'plan improvement' stage by a draftsman fits two choices, either to foster a 3D model with more detail and afterward make ensuing sheets and subtleties utilizing a 3D instrument like Revit or AutoCAD, or as is as yet typical, to foster the idea plan in 2D utilizing more conventional techniques. From the reasonable plans given by draftsmen and specialists, a drafter can change over these plans utilizing computer aided design programming projects to make specialized drawings.

Structural drafting is the most common way of making specialized drawings which incorporate the floor plan, segments, rises, nitty gritty drawings and different records in a development drawing set (Disc Set), which are regularly expected for the development of a structure.
