fabricators.<\/li>\n<\/ul>\n<\/aside>\n\n\n\n<p class=\"wp-block-paragraph\">Since CAD (computer-aided design) first came on the scene in the 1950s, CAD drawings have completely transformed how products, buildings and even aeroplanes are designed. But, what is CAD drawing?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Initially, CAD was only used by big manufacturers, as Norman Sanders explains. Boeing was one of the first to use it to design aircraft like the 727 in the early 1960s. Over the years, CAD has gone from being a bit of a niche tool for aerospace to being a core part of almost every design-oriented industry, from architecture to entertainment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It&#8217;s not just made drafting quicker and easier, but it&#8217;s also made the design process more precise and efficient.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_a_CAD_Drawing\"><\/span>What is a CAD Drawing?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CAD drawing is a way of creating digital representations of designs using a computer. These lets designers create 2D or 3D shapes, see how things fit together, and run simulations like animation or structural analysis. Usually, CAD drawings are used a lot in engineering, architecture, and manufacturing, as well as lots of other industries.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"History_of_CAD_drawing\"><\/span>History of CAD drawing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/03\/interscale-what-is-cad-1024x576.webp\" alt=\"What is CAD drawing\" class=\"wp-image-3323\" title=\"\" srcset=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/03\/interscale-what-is-cad-1024x576.webp 1024w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/03\/interscale-what-is-cad-300x169.webp 300w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/03\/interscale-what-is-cad-768x432.webp 768w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/03\/interscale-what-is-cad-800x450.webp 800w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/03\/interscale-what-is-cad-600x338.webp 600w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/03\/interscale-what-is-cad.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">What is CAD drawing (Image by INTERSCALE)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The creation of CAD drawings was made possible by software like PRONTO, which came out in 1957. It helped transform design instructions into digital information that could be used by machine tools.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Later, software like Sketchpad in 1963, let designers interact directly with the design on a computer using tools like a light pen. Which was a bit like a modern mouse. These early systems led to a shift from 2D to 3D modelling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the first 3D modelling techniques was wireframe design, which represents objects using points connected by lines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Surface design was a big step forward. It used mathematical functions to accurately describe and represent the surfaces of objects, which paved the way for solid modelling and parametric modelling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The IBM PC, which came out in 1981, was a big turning point for CAD. It made the technology more affordable and accessible, which led to it being used much more widely. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And there are software like AutoCAD in 1982. This software really changed the game. It made some pretty sophisticated design tools available to a broader range of users.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a comparison of two popular CAD software in the market, kindly read <a href=\"https:\/\/interscale.com.au\/blog\/bricscad-vs-autocad\/\">&#8220;BricsCAD vs AutoCAD: Which Software is Better For Your Project?&#8221;<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Types_of_CAD_Drawings\"><\/span>Types of CAD Drawings<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CAD drawings are not one single output, which is why in Australia AEC projects, the drawing type changes depending on who needs the information next: a designer, estimator, site team, fabricator, supplier, or maintenance team.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2D_Technical_Drawing\"><\/span><strong>2D Technical Drawing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 2D technical drawing shows a design in flat views, such as plans, sections, elevations, details, or part drawings. It usually includes dimensions, notes, symbols, title blocks, and annotations so the design can be checked, issued, priced, or built from.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3D_Model\"><\/span><strong>3D Model<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 3D model shows the design with depth, form, and spatial relationships. A Brisbane manufacturer designing a new component may use a 3D CAD model to check fit and clearance before issuing 2D drawings to a supplier.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Construction_Drawing\"><\/span><strong>Construction Drawing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A construction drawing explains how a building, structure, service, or site element should be built. For a 40-person contractor, these drawings often become the daily reference for site teams, subcontractors, consultants, and project managers, so revision control matters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Shop_Drawing_and_As-Built_Drawing\"><\/span><strong>Shop Drawing and As-Built Drawing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A shop drawing shows how a specific item will be fabricated, assembled, fixed, or installed before it reaches site. An as-built drawing records what was actually built after site changes, which helps future maintenance, compliance checks, and handover work.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Common_CAD_File_Formats\"><\/span>Common CAD File Formats<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CAD file formats below matter because the wrong format can turn a clean drawing into a rework problem:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>DWG: A common AutoCAD drawing format used for CAD drawings and documentation.<\/li>\n\n\n\n<li>DXF: A drawing exchange format used to move drawing data between CAD applications.<\/li>\n\n\n\n<li>STEP: A neutral 3D model exchange format often used in mechanical and product design workflows.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Before sending files outside the business, confirm the required format, software version, and export settings<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A Sydney fabrication business may receive DWG drawings from a consultant and STEP models from a supplier, so intake rules need to define which file becomes the production reference.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Advantages_of_CAD_drawing\"><\/span>Advantages of CAD drawing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Make_sure_the_design_process_more_precise\"><\/span>Make sure the design process more precise<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">One of the best advantages of CAD drawing is how it makes the design process more precise. CAD gets rid of the mistakes and inconsistencies that can happen when you&#8217;re drawing by hand because it defines shapes and dimensions mathematically.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Improve_efficiency\"><\/span>Improve efficiency<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As well as being super precise, CAD can automate lots of parts of the design process, which makes things even more efficient.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Avoid_physical_prototypes\"><\/span>Avoid physical prototypes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Another benefit of CAD drawings is that they can help you avoid having to produce physical prototypes, which can be expensive and time-consuming. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Improve_project_collaboration\"><\/span>Improve project collaboration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With CAD, it&#8217;s easy to share and access design info across teams and locations, which makes the design and manufacturing process a lot more streamlined and ensures that everyone&#8217;s working from the same accurate data.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Easy_to_integrate\"><\/span>Easy to integrate<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Integrating CAD with product data management (PDM) and product lifecycle management (PLM) systems makes these benefits even better. We should also give a big shout-out to CAD for changing the way we design and the skills engineers and designers need.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here are several reviews of good open-source CAD software you can get in the market <a href=\"https:\/\/interscale.com.au\/blog\/best-cad-software-for-mac\/\">&#8220;Best Options of CAD Software for Mac in 2026 \u2013 Free &amp; Open Source.&#8221;<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Disadvantages_of_CAD_drawing\"><\/span>Disadvantages of CAD drawing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Since CAD history began, one of the biggest hurdles for newcomers has been the high cost of the software and the powerful workstations you need to run it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another downside to CAD is that it can take a while to get to grips with some of the more advanced software. As CAD programs get more complex, it can be tough for new users to get up to speed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We should also talk about how different CAD software packages work together. Using different file formats can make it tricky to share designs between users of different programs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While there are ways to get around this, like converting files or using import options, these can be time-consuming and sometimes result in data loss or formatting inconsistencies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then, consider how training time depends on the role and the drawing output. A junior drafter learning 2D documentation has a different path from a designer moving into 3D modelling, parametric tools, or BIM-linked workflows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For more breakdown on the challenge and disadvantages, see our guide on <a href=\"https:\/\/interscale.com.au\/blog\/is-cad-drawing-difficult-to-learn\/\">is CAD drawing difficult to learn<\/a>?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"CAD_Drawing_vs_BIM\"><\/span>CAD Drawing vs BIM<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CAD drawing is mainly used to create digital drawings and models, while BIM connects the model with project information. That information can include materials, quantities, asset data, classifications, and coordination details.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a case in a 30-person architecture practice: CAD may still be enough for drafting, details, and drawing issue sets. If the same team starts coordinating models with engineers, contractors, and quantity workflows, the <a href=\"https:\/\/interscale.com.au\/blog\/cad-vs-bim-how-is-bim-different-from-cad\/\">CAD vs BIM<\/a> decision becomes more important.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s why the question is what the model has to carry after the drawing is issued. If the model needs to support coordination, quantities, construction sequencing, or handover data, BIM becomes part of the workflow discussion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_a_CAD_Drawing_Example\"><\/span>What is a CAD Drawing Example?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad-1024x576.webp\" alt=\"what is autocad\" class=\"wp-image-7219\" title=\"\" srcset=\"https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad-1024x576.webp 1024w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad-300x169.webp 300w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad-768x432.webp 768w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad-747x420.webp 747w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad-696x392.webp 696w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad-1068x601.webp 1068w, https:\/\/interscale.com.au\/blog\/wp-content\/uploads\/2024\/10\/what-is-autocad.webp 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">A good example of a CAD drawing is one you&#8217;ll see in architectural design. Just picture an architect designing a residential building.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With a CAD program like AutoCAD, the architect can create detailed drawings of every room, wall, and window with exact measurements. Being able to create 3D views from these drawings makes it simpler for both the architect and the client to visualise what the finished building will look like.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another example is a mechanical engineer who has to design an engine component. CAD software like Siemens NX lets engineers create 3D models of parts, run stress tests to see how they&#8217;ll hold up, and check that they&#8217;ll fit perfectly in the engine assembly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Small_Businesses_Can_Adopt_CAD_in_a_Cost-Effective_Way\"><\/span>How Small Businesses Can Adopt CAD in a Cost-Effective Way<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">What&#8217;s in it for small businesses if they adopt CAD? In today&#8217;s competitive market, staying ahead means delivering designs that are precise and efficient. For small architectural or engineering firms, CAD tools are a must if you want to produce high-quality work. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can learn about some CAD software options at <a href=\"https:\/\/interscale.com.au\/blog\/free-cad-drawing-software\/\">Top Free CAD Drawing Software: Features, Benefits, &amp; How to Choose<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, as we said earlier, cost can be a big issue. So, how can we make CAD more affordable?&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For Australian teams with 15\u2013100 staff, we suggest cost planning usually starts with seat mix, renewal timing, and access needs. Some users need full drafting access every day, while others may only need to review drawings, check files, or approve revisions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Or consider using accelerated <a href=\"https:\/\/interscale.com.au\/services\/software-licensing\/autodesk-autocad\/\">Autodesk AutoCAD licensing support<\/a>, so you can get CAD drawing and BIM solutions up and running without breaking the bank.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Interscale\u2019s BIM Management services provide solutions you can scale up or down to suit your needs.
