Computer-Aided Design (CAD) Surveys & CAD Drawing Services 

Accurate CAD surveys are the foundation of successful projects. At South West Surveys, we specialise in survey-grade CAD drawings based on detailed and accurately built measured building surveys.

Our CAD survey empowers architects, developers, contractors, and professional surveyors to deliver successful projects with high accuracy.

What Is a CAD Survey

Computer-Aided Design (CAD) survey converts on-site measured building survey data into accurate and precise digital designs or models.

With our state-of-the-art laser scanning technology, we ensure our measured building surveys contain all captured dimensions, structural details, and features that are pivotal in the design and development stage of any project.

CAD Surveys enable designers to make changes and adjustments to designs quickly and easily, without having to start from scratch.

Types of CAD Surveys

From small components to complex projects, CAD Surveys revolutionise the way surveyors visualise, design, and plan projects. At South West Surveys, our CAD surveys are tailored to project needs.

Two main types of CAD drawings help us deliver successful projects:

2D CAD Drawings

Two-dimensional images created using basic geometric shapes are helpful for technical drawings, including:

• Floor plans with accurate room layouts and dimensions
• Elevations showing façade geometry and openings
• Cross sections illustrating internal structure and levels
• Roof plans and site layouts, where required

3D CAD Drawing

3D CAD drawings are three-dimensional images that help build models and highly accurate 3D designs. Clients can visualise their design in real life and better understand any challenges or opportunities with their upcoming projects.

3D CAD drawings are typically used for:

• Massing and volumetric models
• Internal spatial layouts
• Models suitable for coordination with BIM workflows

Why Is CAD Survey Important

CAD drawings are frequently used across different project phases. Therefore, if any errors exist at this stage, they will just continue to propagate across the design, planning, and construction stages of any project.

Therefore, a highly accurate CAD Survey is the foundation of any successful project and helps in:

• Reflecting the true conditions of the site
• Reducing assumptions and data hallucinations
• Supporting accurate planning submissions
• Improving coordination between project stakeholders
• Minimising the risk of redesigns and site queries
