Accurate 2D CAD Plans From 3D Laser Scanning
Convert existing buildings, sites and assets into clean, accurate CAD drawings for design, refurbishment, leasing, construction and asset documentation.
2D CAD Drawings for Existing Buildings, Sites and Assets
Reliable CAD drawings are essential when working with existing buildings. Whether you are planning a refurbishment, preparing design documentation, managing a commercial property, coordinating consultants or updating old building records, your team needs CAD plans that reflect the real site conditions.
3D Walkabout provides professional 2D CAD plans created from 3D laser scanning and point cloud data. We capture the existing building or site, process the scan data and produce accurate DWG and PDF drawings that can be used by architects, engineers, builders, project managers, asset owners and facility managers.
Our 2D CAD drawing services can include floor plans, elevations, sections, reflected ceiling plans, façade drawings, site plans and as-built documentation. The level of detail is tailored to the project, so you receive drawings that are practical, editable and suitable for the way your team needs to work.

THE SERVICE
What Is an Existing Conditions Survey?
2D CAD plans are technical drawings produced in a computer-aided design format, commonly supplied as DWG files. They document the layout, geometry and key features of a building, space or asset in a clear 2D format.
For existing buildings, 2D CAD plans are often created from measured survey data or 3D laser scan data. This ensures the drawings are based on actual site conditions rather than old plans, assumptions or manual sketches.

SCOPE
What Can Be Included in 2D CAD Plans?
The information shown in the CAD drawings depends on the intended use. A leasing plan does not need the same detail as a refurbishment drawing package. A façade elevation is different again from a construction coordination section. Depending on the scope, 2D CAD plans can include:
The aim is to produce drawings that are accurate enough for the job, without adding unnecessary detail that increases cost and makes the files harder to use.
WHY LASER SCANNING
Why Create CAD Plans From 3D Laser Scanning?
Creating CAD plans from 3D laser scanning is one of the most reliable ways to document existing buildings. The laser scan captures the real site conditions as a measurable point cloud, and the CAD drafting process converts that data into clean 2D drawings.
This approach is much stronger than relying on old drawings or isolated manual measurements. Many buildings have changed over time. Walls are moved, fitouts are altered, services are upgraded and undocumented works are completed. As a result, the available plans may no longer match the building.
By creating CAD drawings from current scan data, your team can work from an accurate base. This helps reduce design assumptions, improve coordination and avoid costly errors caused by incorrect existing-condition information.
FOR YOUR TEAM
2D CAD Plans for Architects, Engineers, Builders and Property Teams
Different project teams use 2D CAD plans in different ways. Architects may need editable base plans before starting design. Engineers may need sections, levels or structural references. Builders may need existing-condition drawings to plan works or coordinate trades. Property teams may need accurate plans for leasing, asset records or future upgrades.
Because CAD drawings are widely used across the design and construction industry, they remain a practical deliverable even when point clouds or BIM models are also available. They are easy to issue, mark up, measure, print, revise and include in design documentation packages.
For many projects, the best workflow is a combination of outputs: a registered point cloud for reference, CAD drawings for day-to-day documentation and, where needed, a BIM model for coordination. 3D Walkabout can help define the right combination based on the project stage and intended use.

BENEFITS
Benefits of 2D CAD Plans From Laser Scan Data
CAD STANDARDS
Practical CAD Files Your Team Can Actually Use
The value of a CAD drawing is not just the accuracy of the geometry. It also needs to be structured properly so project teams can work with it. Our CAD deliverables can be prepared with practical drafting considerations such as:
Logical layer structure
Clear linework hierarchy
Consistent naming conventions
Editable DWG geometry
Separate layers for walls, openings, columns and features
Sheet layouts for PDF issue
Drawing titles and revision references
Appropriate scales for the project
Clean drawing presentation
Reduced unnecessary point cloud clutter
Coordination with supplied title blocks where required
Output formats suited to your consultants
Where a client or architect has specific CAD standards, we can discuss these before drafting begins.
USE CASES

PROCESS
From Laser Scan to 2D CAD Drawing
GETTING THE SCOPE RIGHT
Getting the Scope Right Before Drafting Starts
A good 2D CAD plan starts with a clear brief. If the drafting scope is too vague, the final CAD drawings may be under-detailed, over-detailed or structured in a way that does not suit the team using them. Before we begin, it helps to confirm:
WHY US
Built for Design and Construction Teams
CAD Drawings From Current Site Conditions
If your existing drawings are missing, outdated or unreliable, we can scan the building and create new CAD plans from the current site condition.
Clear Outputs From Complex Scan Data
Point clouds are powerful, but not every project team wants to work directly from raw scan data. CAD plans make the information easier to issue, mark up and use.
Ideal When BIM Is More Than You Need
A full BIM model is not always necessary. For many projects, accurate 2D CAD plans provide the right balance of detail, usability and cost.
Built for Design and Construction Teams
Our CAD drawings are created for practical use by architects, engineers, builders, contractors, property teams and asset managers.
Frequently Asked Questions
What are 2D CAD plans?
2D CAD plans are technical drawings created using computer-aided design software. They show building layouts, elevations, sections or other measured information in a clear 2D format, usually supplied as editable DWG files and PDF drawings.
How are 2D CAD plans created from laser scan data?
The site is captured using 3D laser scanning, which creates a detailed point cloud of the existing conditions. Our drafting team then uses that point cloud as the measured reference to create accurate 2D CAD drawings.
What is the difference between 2D CAD plans and measured floor plans?
Measured floor plans are usually one type of 2D CAD output. A 2D CAD plan package can be broader and may include floor plans, elevations, sections, reflected ceiling plans, façade drawings, site plans and other technical drawings.
What file formats can you provide?
We can typically provide DWG and PDF files. Depending on the project, we may also provide point cloud data, DXF files, drawing sheets, Revit models or other agreed formats.
Can you create CAD plans if we do not have existing drawings?
Yes. Many projects start with no reliable drawings. We can scan the building or site and create new CAD drawings from the captured data.
Can you update our existing CAD files?
Yes, in many cases. If you already have CAD drawings, we can use laser scan data to check, correct and update them. The amount of work required depends on the quality of the existing files and how much the building has changed.
What level of detail can be included in the CAD drawings?
The level of detail depends on the scope. Drawings can include walls, doors, windows, columns, stairs, structural elements, ceiling features, services zones, fixed joinery, room labels, dimensions, levels and other agreed information.
Are 2D CAD plans suitable for architects and engineers?
Yes. 2D CAD plans are commonly used by architects, engineers and consultants as existing-condition base drawings for design, coordination, documentation and construction planning.
Do I need 2D CAD plans or a BIM model?
If your team needs editable drawings, 2D CAD may be the best option. If the project requires model-based coordination, clash detection or Revit workflows, BIM may be more suitable. Some projects use both.
How accurate are CAD plans created from laser scanning?
Laser scanning provides a highly accurate measured dataset, but the final drawing accuracy depends on the scan methodology, registration process, drafting scope and required level of detail. We confirm the intended use before starting so the drawings are produced appropriately.
Can you provide CAD plans for multi-level buildings?
Yes. We can create CAD drawings for individual tenancies, multi-level commercial buildings, residential properties, industrial facilities, campuses, public buildings and larger property portfolios.
Can CAD plans include elevations and sections?
Yes. We can produce elevations and sections from the scan data where required. These are commonly used for refurbishments, façade works, design coordination, heritage documentation and construction planning.
