Why The Time-tested Practice of Architectural Drafting is Used in Architectural Design?

Why the time-tested practice of Architectural Drafting is used in Construction and Architectural DesignArchitectural drafting, a time-tested practice of drafting 2D architectural construction drawings has evolved from manual 2D drawing to using computer-aided design and drafting (CAD) software programs. 2D drawing sets have been used and will continue to be used by engineers, designers and architects as standard deliverables to contractors on construction sites.Architectural drafting, a time-tested practice of drafting 2D architectural construction drawings has evolved from manual 2D drawing to using computer-aided design and drafting (CAD) software programs. 2D drawing sets have been used and will continue to be used by engineers, designers and architects as standard deliverables to contractors on construction sites.

In most building projects today you may have noticed an increase in the use of architectural BIM modeling and 3D models. Architectural 3D modelling is useful because 3D architectural construction drawings and models allow for design changes in real-time, easier management and exchange of project data and it provides a 3D view of the conceptual plan. However, architectural drafting is preferred by several construction companies because it includes technical details of structural, architectural and electrical components required for installation and during construction of a building. A construction drawing set (CD set) of architectural CAD drawings typically includes sections, elevations, floor plans, detailed drawings for installation of MEP components and other documents required for construction.

Architectural CAD drawings help in construction and architectural design by specifically communicating the design intent and by providing high-performance detailing of construction elements. To understand why the time-tested practice of architectural drafting is commonly used in architectural design and construction projects, here are some of the reasons:

• While architectural design companies have technical resources and drafting teams qualified to deliver 2D technical drawings using basic software programs such as AutoCAD, not all companies have the availability of technical resources qualified to deliver 3D models using software programs such as Revit. Moreover, most of the resources employed in construction teams are qualified to interpret 2D architectural construction drawings required for construction while not all resources working in various disciplines are experienced to use 3D models.

• In the construction industry, the adoption of new practices and the latest software is a slow and gradual process. The software programs used in architectural design and building projects varies from country to country, with some using AutoCAD and ArchiCAD instead of Revit, invariably resulting in the incompatibility of project data. 2D architectural CAD drawings are widely adopted across the industry and are preferred over Revit 3D models for construction.

• While 3D models provide additional information, not all building projects require this data to complete construction. 2D architectural CAD drawings in a construction drawing set include symbols, technical codes, quantities, the type of material and other additional information included in the elevations, sections, floor plans and detailed drawings that are required for successfully completing a construction project.

• One of the underlying reasons why architectural drafting solutions are commonly used is the fact that 2D technical drawings are economically viable and provide sufficient project data to complete construction. Moreover, added to the cost of architectural 3D modelling solutions, there is an additional investment in technical resources qualifies to interpret architectural 3D models for construction on-site.

The practice of using 2D architectural construction drawings on-site will continue to be a preferred option because construction companies and teams need more than a 3D perspective of the conceptual plan, they need precise details and accurate drawings for construction and detailed technical drawings more than an aesthetical perspective. Moreover, in the construction industry, most of the resources can interpret 2D drawings clearly and not all manpower of various disciplines in a construction team have the capability to comprehend 3D models. Added to that, 2D drawings are compatible because basic software programs such as AutoCAD and ArchiCAD is required unlike when using 3D models where there are certain cases of software incompatibility. While architectural design and construction companies gradually adopt architectural 3D modelling and BIM modelling solutions, architectural drafting and drawing solutions will continue to be a commonly used practice because it meets the requirement of efficient and effective construction on time and within budget.

Advantages of CAD Drafting over Manual Drafting

Computer Aided Design (CAD) has been a real breakthrough in the AEC industry by becoming the primary source of communicating design intent. Before the advent of CAD, the only source for draftsmen was pencil and paper for drawing sketches. The traditional method of manual drafting is iterative and time consuming. However, now there has been a paradigm shift from traditional manual drafting to cad design and drafting.

Some of the benefits of CAD Drafting are as follows-

Data storing and Accessibility – One of the advantages of CAD drafting is that the drawings need not be filed and stored in folder unlike in manual drafting. CAD drafting can be easily saved on the computer server and can be accessed from anywhere with internet connection. The chance of losing the documents is higher in manual drafting. As CAD drawings can be saved electronically without the use of paper, it is also an environment friendly method.

3D views – 3D drawings are the best way to virtually represent a structure. Though one can manually create a 3d model, it wouldn’t look as realistic as the 3D model generated by AutoCAD. AutoCAD breathes life in the 3D model and aid the visualization process. While creating 3D view manually is a challenging, time-consuming and tire-some job,   it becomes much easier with software like AutoCAD.

Revisions – While you create any drawing on paper or software, there is bound to be some amount of revisions or modifications. In manual drafting, you need to erase and redraw to make any modification to your drawing. CAD simplifies the revision process to a large extent with its various editing tools. With few clicks of mouse, you can undo, redo or delete your actions. You need not re-draw an object anytime later as you can modify the existing object by mirroring, stretching, rotating, scaling etc.

Speed and Time – Technologies are invented to make our work easier, save our time and to complete the work faster. AutoCAD is significantly faster than the traditional method of manual drafting. It speeds up the task of preparing bill of materials, reports, scaling etc. The tedious task of drawing each line on paper can be done in few mouse clicks. As CAD software eliminates repetitive iterations, a substantial amount of time is saved. In AutoCAD, data describing a component or its family is associative in nature and hence revisions are automatically made to all places the data is used.

Accuracy – In manual drafting, all the objects drawn must be of correct size and alignment. Each object need to be manually verified and dimensioned as the slightest error can be catastrophic to the entire project. With CAD, there are numerous techniques available to obtain exact dimensions thus leading to improved accuracy in the project.

Owing to the numerous benefits in terms of speed, accuracy, data storage, revision CAD offers over manual drafting, it has become a standard for the AEC industries.

Integrated Project Delivery (IPD)

IPD (Integrated Project Delivery) adoption helps to ensures closer working relationships within the entire design team and the supply chain for construction and engineering projects.

As a collaborative process IPD allows utilizes modern technology, teams from all stages of the construction process and the respective processes and practices of these teams to deliver projects on time and on budget.

These teams are brought together at the start of a project to ensure that all stages of the project are ‘integrated’. The IPD structure and concept was formulated in response to the decreasing levels of productivity and profitability in the construction sector. With the aim of an improved project outcome upon adoption of the IPD approach. IPD also allows management of risk allocation while focusing on the needs of the end client.

By adopting the principles of IPD, customers hope to reduce wastage while optimizing efficiency during the design, manufacture, installation and construction stages of the project.

At XS CAD India we provide a range of services to allow our customers to adopt the IPD principle and approach. We do this by providing the technology infrastructure (a range of online collaboration tools), a technical delivery solution (using Revit BIM Modeling software) and a project methodology that is required to generate and control all design output that is generated from the IPD process.

Our involvement on IPD projects is focused around high quality management and delivery of design data – whether this is 3d models, bills of quantities, construction drawings or record drawings.

Our aim is to ensure that all parties involved in the project (beyond the initial architect, client and main contractor) are bought into an overall standard for the production and use of design and construction data. By ensuring involvement of all stakeholders (including fabricators and specialist contractors) throughout the design process, we enable customers to benefit from adoption of IPD even when they are not yet fully equipped to do so with their existing resources.

Our engagement model for IPD projects varies and is dependent on the type of project and also on our scope upon appointment. Our IPD support services range from initial consultation for project standards to complete management and execution of a range of IPD support services.

Revit Family Modeling

By creating models directly in Revit and using the Revit family function, we are able to create intelligent, parametric models for a range of construction and engineering components for builders, specifiers, manufacturers and designers.

As Revit uses parametric modeling functionality which means that as long as a model is created with a set of rules then re-sizing a model will be controlled. This control comes about from the level of rules and the relationships that are built within the dimensions of the part or the assembly.

As well as control of the dimensions, XS CAD India is able to create family models that have other parameters such as formula and imported data (such as a surface finish). Our parametric models also include constraints which allow the set up and establishment of relationships between various entities within a particular part or shape.

Our ability to create Revit Family models allows designers to use accurate models for any aspect of their internal or external design for construction projects whether this is for bespoke window design, distinct interior furniture or for precisely defined mechanical valves that have relationships to control re-sizing.

We already have experience of creating Revit Families for mechanical, electrical and ventilation components used for Revit MEP projects as well as furniture, data, bespoke retail interiors and wall finishes for Revit Architecture projects.

Providing designers with Revit Family models is becoming essential to ensure that manufacturer’s products are specified in a design at the start of a project. As such it is becoming increasingly essential to create and provide Revit family models for each and every product that is designed and manufactured. At XS CAD India we provide a service to create a library of Revit family models. Once created we are also able to provide a service for updating the library with new models as they are added to the product range.

Revit BIM Modeling

Revit BIM Modeling provides unrivalled output of construction focused, design data for all types of construction projects thereby allowing project teams to benefit from improved design data and processes from the design table right through to the construction site.Revit is a database driven software utility, which means that changes to schedules, plans, elevations, sections or the 3D model itself result in coordinated updates to all corresponding areas. This is referred to as ‘integrated bidirectional associativity’ by Autodesk.

Revit is helping BIM software to become the design standard for many architects and general contractors, with benefits ranging from intelligent models that contain actual construction data to interference checking and site phasing tools.

Due to the database structure of Revit, the application allows for a range of other benefits including material takeoff and improved compatibility with other Autodesk software. One such tool is the gbxml (Green Building Mark Up Language) utility, which can be used to analyze and manipulate energy aspects of the building including the carbon footprint. XS CAD India is able to provide building analysis services (working towards carbon neutrality) using Autodesk’s Green Building Studio application.

At XS CAD India we provide BIM Modeling services via the Autodesk Revit suite of products which include Revit Architecture, Revit Mep and Revit Structures. Our Revit project experience includes development of construction drawing sets for leading homebuilders in the US and Canada, development of models and associated drawings and schedules for multi-use buildings in the UK, US, Middle East and Australia including high-rise structures and creation of Revit based construction drawing sets for retail design updates.

Using Autodesk’s Revit software as our main BIM tool, we create intelligent BIM models (Building Information Models) that contain parametric models. These models are intelligent and will re-size according to actual manufacturing data that we have used to create them through our Revit Family Modeling services.

If you would like to learn more about our Revit BIM services then please do not hesitate to contact us for more information.
