Architectural Drawing is the important and most basis foundation of any building design and construction project. They are not just plans or diagrams but a visual language of communication between architects, engineers and builders. Architectural drawings are not sketches made ‘in one go’; they can be more of an assembly process, resulting in clear and precise technical documents done with CAD drafting and BIM modeling tools. They specify layout, dimensions, materials, and how things are put together. In this blog, based on our research findings, we will discuss the 12 most important types of architectural drawings and their uses to explain why they are a must-have for today’s construction professionals.
