A Bitesize Guide To CAD Design For Buildings

The move from hand-drawn design to computer generated ones using a piece of software is a leap that many have already taken. Others are not so sure, especially when it comes to CAD design for buildings. Why make the switch?

Produce very accurate designs

With CAD, you can create 2D and 3D designs, both of which can be rotated within the software allowing for different views of the building. CAD designs bring many more features to the design process, but when it comes to scaling, you can create a design that gives a more accurate overview.

Start by drawing

When you draft manually, you will select a sheet with a pre-printed border and title block. You determine the views, elevations, sections and other details and then, you start to draw. With CAD designs, the process begins with a drawing or a model. This model space is then used as the basis to create the layout of the building, usually in an area called the paper space.

In effect, this allows you to be creative without committing. It provides a chance to zoom in and out on detailing, as well as the views in the viewport section.

Organise your information

With manual drawing, different information is layered onto the original plan using transparent overlays. In other words, a transparent sheet for electrical cabling, another for the plumbing, another for structural elements and so on.

CAD designs also have the equivalent to transparent overlays, so you don’t lose any of this detail. You can see the detailed information singularly, just as you would by layering a transparent layer over the plan or use them in combination so you can see pinch points with drainage or cabling.

Effectively, CAD designs of buildings are all about making design simple, easier but just as effective. You can quickly evaluate whether the building design meets industry standards and regulations as it provides the detailing designers and architects need.

Promotes efficiency

Drafting manually is repetitive. Constantly removing things, adding sections and so on – in other words, all that ‘editing’ needs to be done on the paper.

With CAD designs of buildings, there is an efficiency that allows for easier drafting in so many ways. In fact, you can set new standards of drafting with CAD.

From line weight to text styles, there is a delightful design finish to many plans…

Easier to understand plans

It isn’t just about looks, but as a designer, you have an eye for detail and of course, an eye for the creative edge of a product. Why wouldn’t you want your building designs to look pleasant and attractive to the eye?

Isn’t that what attracts clients to your practice? But you also want your client to have an understanding of what they are looking at.

With flat plans, this is difficult, even for those of us with years of experience of understanding how the building will look from pencil drawn ‘front elevations’!

CAD designs allow your clients to ‘see’ the building. They can have an appreciation of what it will look like, how it fits the landscape. Easier to see, they will also feel more part of the project, and for you, that means a win-win when it comes to designing the building they not only want but love.

Easy modifications

Changes happen. They happen at the request of a client, and they occur when they need to because as the build starts, unseen issues crop up.

Instead of a significant redesign headache, you simply return to the drawing, move and change things. Even better, the accuracy of using CAD is far improved that spending time at the drafting table.

There are more reasons why CAD designs work for building design, but surely, these alone are enough persuasion to take a closer look?
