We cannot completely claim that CAD software is essential to creating stunning, towering structures since pyramids, temples, and other wonders of architecture predate this tool by thousands of years. However, in the modern age, not using this technology would be a shame as it offers loads of tools to streamline the design process.
If drafts are created manually, a lot of inconveniences may arise. The most glaring ones are time and cost constraints. The bigger and more complicated projects are, the longer it’ll take for the design process to be completed, and the more money will be spent on it. Presentations of models, approval of specs, and revisions are just some of the problem scenarios that CAD software helps with.
Not only that, but it also improves the quality of the finished product by mixing computational and design tools with the ingenuity of the users. The article provides a more detailed explanation of what CAD software can do.
What is CAD Software?
CAD software is used in place of manual drafting tools and replaces them with automated processes when making designs and preparing design documentation. While it sports other features, such as collaboration and cost estimates, at its core, this type of tool’s primary function is for design. Creating 2D curves and figures, rendering objects from any angle, and building 3D solids and surfaces, to name a few.
What does CAD software do?
CAD software allows engineers and other users to create designs through raster or vector graphics. Aside from making designs, it also lets you visualize concepts with the help of photorealistic rendering, three-dimensional rotation, physics-based lighting, and more. And since everything here is done digitally, this means that the design created can be easily saved, shared, and updated.
Aside from those, CAD software is also the ideal tool for documenting designs. It helps standardize designs throughout the project lifecycle. The system also decreases the chances of errors as many CAD tools provide functions for visualizing the final products. There are even some tools with animation features to see how the visualized final product would work.
Who does CAD software help?
CAD application’s most frequent users are those who design, visualize, or create physical objects, structures, buildings, etc. This typically includes:
- Engineers – a lot of CAD software provides features tailored explicitly for designing bridges, houses, buildings, and other structures. This is mostly used by civil engineers specifically as it also features tools for taking into account environmental factors, such as the landscape, in the design. This solution is ideal for mechanical engineers as well. For instance, the software helps them map out automated processes.
- Architects – architects use CAD software to prepare plans and virtual models of the structures they’re building. After fleshing out their ideas, they then use it to create a presentation for their clients.
- Marine engineers and naval architects – similar to engineers and architects, with the main difference being that the equipment and structures they design are made especially to function on water. This includes the creation of a draft for freighter hulls and interiors of luxury ships.
- Construction workers – they may not be directly involved with the design of the building they make. However, construction crews will benefit from being able to visualize better the structure they’re making.
- Drafters – the work of these professionals is to transform the sketches and specifications of engineers, architects, and others into technical drafts and plans. They rely on CAD software to do this.

Benefits of CAD Software
Visualization of products before building
CAD software lets professionals give a realistic view of the design they make for people to see. For example, architects can show the visualized house structure to their customers. This way, clients can also learn more about what they’re paying for, and they can give feedback more easily in case they want to make some changes.
Accessible storage and easy sharing
Blueprints created through CAD software can be easily stored in a device like a laptop or USB pen drive. They can also be sent to cloud servers for accessible safekeeping. This way, you can easily find what you need and share your design to clients, business partners, or co-workers. The stored copy can also serve as a backup in case you lose your copy.
This type of solution is equipped with all the tools needed to create a blueprint in the most efficient and skillful ways. It has measuring features to ensure the accuracy of the drafts you make. There are professional templates available from some CAD software, too. These could either be ready to use from the templates library or something you create yourself. All of these translate into the accelerated workflow with higher finished quality to boot.
We may have previously identified the most common users of CAD software. However, by no means are those the only ones who benefit from this system. Practically any profession involving designs, especially the more complex ones, can use it. These include businesses from industries such as fashion, calligraphy, and automotive.
Features of CAD Software
CAD systems empower the 2D and 3D design processes, as well as the visualization of ideas and creating presentations out of them. To do these, CAD software is equipped with the following features:
One of the most essential features of CAD software is its set of drawing tools because it’s the backbone of most design processes. This allows the usage of shapes, lines, polygons, and other elements to create a draft or sketch of the design.
3D modeling and rendering
With these features, users can fully visualize their designs. Users can typically create 3D models by pulling and pushing the surface of the design to give them more dimension, effectively converting 2D models into 3D objects. Users will have the tools to explore and interact with those 3D models. Models can also be animated, or extra effects can be added, such as realistic lighting and textures.
With features like grips, users can move, reshape, and manipulate the 2D and 3D objects created using the CAD software. Editing functions such as trim and erase allow the designers to create a more precise and detailed version of the object. The ability to edit models and designs are available to users in real-time. This helps them make meaningful changes to objects from different perspectives.
Extraction of data
CAD software allows for the creation of objects with realism in mind. That’s because designers use the system to make a virtual model of objects that they’re planning to build in real life. As such, the system provides them with ways to extract relevant information from the objects they make for reference. This includes the objects’ attributes, properties, and materials.
Support for various file formats
It’s not unusual for scenarios such as the need to share 3D models and designs with clients and coworkers. That’s why CAD software must allow for the export of designs in different file formats. This will prevent issues, such as incompatibility, from hindering your workflow.
Types of CAD Software
There are two main types of CAD software:
Developed in the early 70s, 2D CAD tools use basic geometric elements such as lines and shapes to create 2D or flat drawings. It’s useful for developing floor and inspection plans, landscaping layouts, and blueprints.
A more advanced tool, it improves upon the graphical capabilities of 2D CAD by allowing the creation of realistic 3D images. It usually requires a degree of professional training to use it effectively for work.
There are three main categories for 3D CAD software, namely wire-frame models, surface models, and solid models.
- Wire-frame models are for creating skeleton-like models with lines and arcs.
- Surface models join 3D surfaces to create models with an invisible background.
- Solid models, on the other hand, is more or less an upgraded version of surface models because they add properties to objects. These include weight, volume, and density. This is the most useful CAD model and is common in engineering designs.
Factors to Consider when Buying a CAD Software
There is currently an abundance of CAD software in the market. A vast number of vendors have created software in this category to meet the demands of both vertical and horizontal industries.
