Architectural drawing software

Many architects use Autodesk AutoCAD as a 2D architectural drawing tool for creating floor plans, elevations and sections. This architectural software speeds up the drawing process with pre-built objects like walls, doors and windows.

Used worldwide by both commercial and residential architects, CAD has replaced manual drafting. It helps users create architectural drawings and designs in either 2D or 3D so they can visualise the construction. CAD enables the development, modification and optimisation of the architectural design process.

Architects design buildings using software focused more on exteriors, while interior designers focus on the inside spaces of buildings, and include furniture, fixtures and other accessories to create a desired look and function.

BIM and CAD serve distinct and sometimes complementary purposes in the architecture and construction industry. BIM workflows typically rely on a 3D model which serves as the central data repository for design intent. This model incorporates detailed data about building components and their relationships, facilitating collaboration and supporting the entire building lifecycle. BIM emphasises information-rich, parametric modelling within a common data environment that supports interoperability and keeps all project stakeholders on the same page.

In contrast, CAD is centred around drafting workflows, focusing primarily on geometric representation. CAD lacks the comprehensive data aspect inherent to BIM and may require more manual updates to ensure the accuracy of project documentation.

Many types of architectural drawings are required during the process of designing, developing and constructing a building. Some are used at specific times and stages, and others (such as floor and site plans) are continuously evolving and being adapted as the project develops.

Software programs that produce architectural drawings enhance collaboration by offering real-time editing, cloud-based access and version control features. These tools enable multiple stakeholders to work concurrently on the same project, ensuring access to the latest versions and reducing errors. Cloud-based (US site) capabilities facilitate remote collaboration, while markup and commenting tools streamline communication. Integration with collaboration platforms (US site) and project management tools centralises project information, promoting seamless coordination between disciplines.

Most architectural drawing programs support importing and exporting drawings from and to other software applications using various file formats. Standard formats include DWG and DXF for 2D and 3D drawings, IFC for BIM data exchange in an open file format, STL for 3D printing, FBX or OBJ for visualisation, PDF for document sharing, SVG for vector graphics and STEP for 3D model data. These capabilities facilitate interoperability and collaboration between design and construction disciplines, helping architects, engineers and other stakeholders to seamlessly exchange and work on drawings and project data authored in various software applications.

Architectural drawings are detailed documents that communicate crucial information about the design and construction of a building. They typically include:

• a title block with project details
• site plans illustrating the building’s location
• floor plans displaying horizontal layouts
• elevations depicting exterior views
• sections revealing vertical cuts through the structure
• detailed views focusing on specific construction aspects
• schedules listing component information
• specifications detailing materials and standards
• a legend explaining symbols
• notes providing additional guidance
• room names and numbers
• scale indicators
• a north arrow for orientation
• grids and dimensions for spatial organisation
• revision blocks to track changes
