Civil CAD Drafting

Every building or industrial structure - be it a home, skyscraper or bridge - requires a set of civil design and drafting diagrams to demonstrate it in detail. Structures are meticulously designed by a team of structural engineers and structural draftsmen. The process of structural drafting serves as the link between contractor and structural engineers. Traditionally structural drafting involves hand drawing of design and blueprints, but with the invent of computer-aided design (CAD) systems, almost all design work is now carried out over computers. Modern structural draftsman use sophisticated CAD software such as AutoCAD, Revit, StruCADD to develop detailed designs and drawings from hand-drawn sketches.

Structural drafters assist the work of architects and civil engineers by preparing and providing necessary technical drawings. Applying regional building codes and industry standards, they carry out calculations, cost estimates and research prior to crafting designs. Structural drawings technically show the details of structures; state materials to be used and processes to be undertaken. Most structural drafters specialize in specific domains such as residential or commercial or by the type of material used like steel, concrete or wood.

The process of structural drafting typically involves study of drafts, instructions and information from the architect or engineer; drafting of layouts for the planned structure; checking and validation of structural drawings to conform to design data and specifications; preparation of construction documents, material and cost estimations. One has to make sure that safety and design standards are followed and drawings get approved from the local authorities for critical projects.

CAD tools generate practical geometric models of objects which can simulate and evaluate the effects and potential drawback of designs. CAD system organizes drawings electronically so that modifications, duplications and variations can be performed with ease. Although structural drafters use CAD to a great extent, it is still a computer tool. This means the structural drafter must have thorough knowledge of drafting skills and industry standards in addition to necessary CAD skills.
