In renovation, remodeling, or office repurposing projects, accurately capturing the current state is the foundation for proposing appropriate design solutions. With Scan2BIM combined with VinaCAD Web Engine, the actual space is digitized into a 3D Model, which is then used to verify the current state, design layouts, and create CAD/DXF drawings.

In this case study, an office area of approximately 200 m² digitized using LiDAR-integrated devices combined with Scan2BIM. The 3D model is then imported into VinaCAD Web Engine for inspection, layout design, and the use of AI to support the creation of additional layout options.

1. As-built digitization with Scan2BIM

The first step is to directly record the actual space using a LiDAR-integrated device combined with Scan2BIM. In this case study, an office area of approximately 200 m² was scanned to record existing components such as walls, doors, tables, chairs, partitions, and the spatial arrangement.

The scanning process aims to convert the physical space into an as-built 3D Model, creating input data for subsequent processing steps.

From scan data to 3D Model

While moving through the space, data is recorded and the 3D Model is gradually formed. The operator can track the scanned areas and continue recording the remaining parts of the space.

In this case study, the entire area of approximately 200 m² was scanned in about 7 minutes.

After the scanning process, the data is converted into a 3D Model of the current state.

From here, the physical space has been converted into 3D data that can be further used in the design environment.

2. Import 3D Model into VinaCAD Web Engine

After obtaining the 3D Model, the workflow shifts from as-built digitization to design verification and development. The 3D Model is imported into VinaCAD Web Engine, creating a working environment continuing from scan data.

Instead of starting over from a blank floor plan, users can continue working on data from the actual space.
In VinaCAD Web Engine, the 3D Model can be used to:

Check space dimensions
Observe and confirm the current layout
Develop new layout options
Serve as a basis for creating CAD/DXF drawings.

Check current status before designing

Before changing the layout, users can check information such as area dimensions, distances between objects, positions of tables and chairs, and available spaces for the new arrangement.

The current layout is also visually reviewed on the 3D model to determine which components to keep, change, and which spaces can be rearranged.

After this step, the current 3D Model becomes the basis for developing the design plan.

3. Layout design with AI support

After clearly understanding the current status, the next step is to develop a new arrangement plan.

With VinaCAD Web Engine, users can proactively design layouts as required or use AI integrated directly into the system to support creating additional layout options.

Custom design on demand

Once a specific idea is established, users can proactively build and adjust the layout based on the current 3D Model.

This approach is suitable when the designer has predetermined the spatial organization or specific project requirements.

AI supports creating additional options

In cases where one wants to explore further layout possibilities, the AI integrated directly into the VinaCAD Web Engine can support creating layout options based on current spatial data.

Notably, the AI does not operate on a completely empty floor plan. The option is created based on 3D Model digitized from actual space.

The generated options can be reviewed, selected, and further adjusted according to actual requirements.

AI in this workflow plays a supporting role, not a replacement for the designer. Users still actively select the appropriate option and control the final design.

4. From layout to CAD/DXF drawing

After the layout option is selected and finalized, the next step is to convert the design result into a CAD/DXF drawing.

This is the step that connects the 3D working environment with the familiar CAD process.

The layout option, after being checked and adjusted, can be exported as a drawing CAD/DXF with necessary dimension information.

5. From digitizing the current state to a seamless design workflow

Office case study of approximately 200 m² shows that data generated from the scanning process can continue to be used throughout the workflow steps. The value of the workflow lies not only in creating a 3D Model, but also in the ability to continue using existing condition data in the verification, design, and drawing creation steps.

Users can proactively design according to their own ideas or use AI to explore more options before making a choice and finalizing the design as desired.

Conclusion

In the digital transformation trend of the architecture and construction industry, scanning the existing condition with 3D LiDAR is only the beginning. The real value lies in the ability to connect that existing data with the design process and automated documentation production. Scan2BIM × VinaCAD Web Engine Solution from VinaCAD is the perfect link helping businesses comprehensively digitize the interior design and construction renovation process.
