What is Drafting and Why is it Important?
Drafting is the visual language of architecture, engineering, and construction. It is the process of creating technical drawings that accurately depict and communicate design intent. Drafting provides comprehensive documentation for construction teams to follow.
Drafting plays a crucial role in taking designs from concept to reality. It translates sketches and 3D models into the 2D documentation needed to build, manufacture, and assemble the designed elements. Drafting often comes after the initial design process but before actual construction.
There are several types of drafting:
Architectural drafting - Creating drawings for buildings and structures. These include floor plans, elevations, sections, etc.
Mechanical drafting - Drawing mechanical systems and components like machinery, parts, and piping.
Electrical drafting - Drafting electrical systems including circuit diagrams, lighting plans, motor controls, etc.
Structural drafting - Drawings showing framework, supports, and connections for infrastructure and buildings.
Civil drafting - Site plans, survey drawings, maps, topography representing roads, land, utilities, etc.
In all its forms, drafting creates comprehensive visual guidelines for contractors and builders. Accurate drafting prevents errors, miscommunication, and delays during construction. Though the software has automated parts of drafting, human judgment, and technical drawing skills remain essential. Drafting is a vital link between concept and construction.
Types of Drafting Services
Drafting services encompass a wide range of architectural and engineering drawings that are used throughout the design and construction process. Here are some of the most common types of drafting services:
Design Drafting
Design drafting focuses on creating preliminary drawings that establish the overall layout, look, and feel of a building or structure. This includes drafts like concept sketches, presentation drawings, and schematics that illustrate the general size, scope, and relationships between the major components of a project. These types of drawings help clients visualize the result during the early stages of design.
Design drafters need strong visualization skills to transform initial ideas into drawings. They collaborate closely with architects and engineers to develop the aesthetics, spatial relationships, and functionality of a design. Accuracy is important, but detail is less of a focus at this stage. Design drafting provides the blueprint for more advanced documentation down the road.
Construction Documentation
Construction documentation represents the comprehensive set of detailed technical drawings required to communicate the design to contractors and builders. These include floor plans, elevations, sections, HVAC plans, electrical plans, and material/finish schedules. Drafters ensure every dimension, material, and component is meticulously specified in the documentation.
Drafters must be adept at computer-aided design (CAD) software and building information modeling (BIM) tools to generate the intricacy required. Construction documentation can be used to acquire permits, solicit contractor bids, direct on-site workers, and serve as a reference through all stages of construction. The level of detail prevents misinterpretation and provides legal protection.
As-Built Drafting
As-built drawings document the specifics of a building or structure as it has been actually constructed. Drafters create these based on field surveys and inspections of the finished site, showing any changes or variations from the original design documents. As-builts serve as a record of the final result for owners and facility managers.
Drafters must carefully mark all modifications based on real-world conditions, including material substitutions or relocated features. As-builts also update dimensions that may be slightly different once construction is complete. Having accurate as-built drawings is crucial for remodels, maintenance, repairs, and litigation.
Conversion from Hand Drawings
With older structures, original blueprints may only exist in outdated hand-drawn formats. Drafting services often digitize these legacy documents into modern CAD files. Converting from hand drawings preserves important records in a usable digital form.
This requires carefully replicating all details, annotations, and measurements from the originals. Draftspeople use scanning and tracing techniques to produce vector-based CAD files from raster images. The converted drawings can then be used for building maintenance, renovations, archiving, and other applications. Digitization preserves aging hand drawings and opens new possibilities.
Drafting Software and Tools
Architectural drafting today relies heavily on specialized software to create precise and accurate designs efficiently. While hand-drafting still has its uses, most drafting professionals utilize one of the two major technologies:
CAD vs BIM vs CADD
There are some key differences between the three most common types of drafting software:
CAD (Computer Aided Design)Â is the broadest term for any computer-assisted design software. CAD programs focus mainly on drafting in 2D.
BIM (Building Information Modeling)Â creates intelligent 3D models that incorporate detailed data on every component of a building. BIM is more comprehensive than basic CAD.
CADD (Computer Aided Drafting and Design)Â is an older acronym but generally refers to basic 2D CAD drawing rather than 3D modeling.
Popular Drafting Software Programs
Some of the most widely used software tools in the drafting industry include:
AutoCAD - The industry standard CAD software from Autodesk, used mainly for 2D drafting and detailing.
Revit - Autodesk's flagship BIM program for intelligent 3D modeling. Integrates well with AutoCAD.

Drafting Skills and Training
Becoming a skilled drafter requires developing key abilities. Drafting professionals rely on strong spatial reasoning skills to translate 3D structures into 2D drawings. An understanding of math, geometry, and engineering principles is also essential. Drafters must have an eye for detail to precisely represent every measurement and specification. Creativity also comes into play when developing effective visualizations of complex designs.
Some of the most important skills for drafters include:
Spatial Reasoning - Drafters need spatial reasoning skills to visualize objects in 3D and represent them in 2D. This allows them to translate specifications into accurate technical drawings. They must be able to mentally rotate and manipulate shapes and structures.
Math and Geometry - Drafting requires knowledge of math, geometry, and trigonometry. Professionals need these skills to calculate dimensions, distances, angles, surface areas, and volumes. An understanding of algebra, measurement, and geometry allows for precise drawings.
 Attention to Detail - The ability to be extremely detail-oriented is vital for drafters. They must carefully and accurately capture every measurement, parameter, and specification in a design. Small errors can be very problematic, so strong attention to detail is a must.
Creativity - While drafting relies on technical skills, creativity also comes into play. Drafters seek new perspectives and effective ways to represent complex designs through drawings. Visualization skills allow them to devise helpful illustrations of 3D structures and spaces.
By honing these core aptitudes, aspiring drafters can gain the skills needed for the job. Background knowledge in architecture and engineering is also beneficial. Many complete CAD technician training programs or drafting certificates. Hands-on practice and experience further strengthen one's drafting abilities over time. Developing a well-rounded set of technical, visual, mathematical, and creative skills is key.

Drafting for Specific Projects
There are many different types of projects that require professional drafting services. Here are some of the most common:
Residential Homes
Drafting is critical for residential home design. Architectural draftsmen will create floor plans, elevations, sections, details, and other drawings needed for constructing a house. This includes single-family homes, townhouses, apartment buildings, and more. Drafting provides precise measurements and specifications so homebuilders can accurately construct the design.
Floor plans indicate room sizes, wall locations, doors, windows, stairs, and other architectural elements. Elevations show exterior views of the home. Sections reveal cross-sections so builders understand floor-to-ceiling heights. Details provide closeup drawings of cabinets, railings, fireplaces, etc. Professional residential drafting creates comprehensive documentation for smooth home construction.
Commercial Buildings
Commercial projects like offices, retail stores, restaurants, hotels, schools, hospitals, and more require extensive drafting services. Commercial buildings are often larger and more complex than residential structures. Architectural drafting clearly communicates the construction requirements through detailed drawings.
From structural framing plans to electrical layouts, commercial drafting provides vital visual guidelines. This helps coordinate the work of various contractors and subcontractors. Commercial drafting may also include 3D renderings and models to help owners visualize the finished building. Precise drafting saves time and money during commercial construction.
Landscapes
Not all drafting is about buildings. Landscape design projects also rely on drafting for gardens, yards, parks, green spaces, and other outdoor environments. Landscape drafting provides elevation views, overhead site plans, hardscape/softscape designs, planting plans, irrigation diagrams, lighting plans, and more.
Landscape drafters illustrate the spatial layout and dimensions of hardscapes like patios, decks, fences, paths, pools, etc. Their drawings ensure landscape elements are strategically placed and properly scaled. Technical specifications and notes provide further construction guidance. Accurate landscape drafting is the blueprint for implementing a seamless outdoor design.
Renovations
Existing homes and buildings also need drafting services for renovations or additions. Floor plans must be redrawn to show the remodeling design. Drafters determine where walls can be moved and indicate updated layouts. Drafting helps identify where structural changes are feasible. It also provides details for altering kitchens, bathrooms, flooring, walls, windows, and anything else involved in the renovation.
Proper documentation is crucial for remodeling projects to avoid costly mistakes. Renovation drafting can even include 3D models to reveal how additions will interface with the existing structure. Whether modernizing, upgrading systems, or adding square footage, drafting brings renovation blueprints to life.
Drafting vs. Design Services
Drafting and design are related but distinct services in the architecture, engineering, and construction industries. While they often work hand-in-hand, there are a few key differences between the two:
Drafting focuses on creating technical drawings, plans, and documentation based on design specifications. Drafters take the designs produced by architects and engineers and translate them into the detailed drawings required for permitting, construction, fabrication, and other uses.
Drafters are focused on precision and accuracy in their drawings. Their drawings include specifics like measurements, materials, procedures, dimensions, and more. Drafters are knowledgeable about relevant codes, standards, and conventions that must be followed.
Overall, drafters do not work on the conceptual stages of design. Their role is to accurately translate those finished designs into technical drawings.
Design services involve the actual creation and ideation of building and system designs. Designers determine the look, layout, uses, and other aspects of a project.
Architectural design focuses on aesthetics, spatial relationships, and creating the overall vision for a building. Engineering design tackles technical systems like structural, mechanical, electrical, and plumbing.
Design involves conceiving and strategizing a project at the conceptual level. Designers focus on big-picture ideas and creative solutions. They leave the detailed documentation to the drafters.
So in summary:
Drafting translates finished designs into technical drawings.
Design involves the upfront conceptualization and creation of project designs.
Both are crucial services in taking a construction project from concept to completion. Drafting and design work close together, leveraging their complementary skill sets.
