Computer-aided architectural design

You know how sometimes you like to play with building blocks or draw houses on paper? Well, imagine using a really big computer to help you design buildings that are even bigger than your house! That's what computer-aided architectural design (CAAD) is all about.

Basically, it's a special way of using a computer to make plans for buildings. Architects can use CAAD software to draw and create very detailed plans of buildings before actually building them. Think of it like using a digital building block kit with special tools that help you build and design a whole building.

The software can help the architect see what the building will look like from different angles, how big it will be, how many floors it will have, and many other details. This way the architect can make sure everything is just right before they start building. It saves time, money, and can help catch any mistakes early on, before building problems happen.

So, just like you use your imagination and building blocks to design things, architects use CAAD software to design big things like buildings. And instead of using real building blocks, they use digital ones on a special computer program!
