FAQ

3D scanning is a process of creating a 3D model of an object or environment from data collected by 3D scanning devices. 3D scanning devices use different technologies to collect data, including:

• Laser scanner: Uses laser beams to measure distances to surfaces of objects.
• Camera stereo: Use two or more cameras to take pictures of objects from different angles.
• Cảm biến Structured Light: Use a light source and a camera to create light patterns on the surface of an object.

3D scanning has many advantages compared to traditional measurement methods, including:

• High accuracy: 3D scanning can create highly accurate 3D models, enabling designers and engineers to make more accurate decisions.
• Fast speed: 3D scanning can produce 3D models in a short time, saving time and costs.
• Versatility: 3D scanning can be used to scan objects or environments of different sizes and shapes.

3D scanning also has some disadvantages, including:

• Cost: The initial investment cost for 3D scanning equipment is quite high.
• Skills: To use 3D scanning devices effectively, users need specialized knowledge and skills.

Scan to BIM is a process that converts 3D models created by 3D scanners into BIM format. A BIM model is a digital model of a building or construction, including information about the building’s shape, materials, and other characteristics.

Scan to BIM is used in many different fields, including:

• Construction: Scan to BIM is used to create BIM models of construction projects, enabling engineers and architects to design, construct and manage projects more effectively.
• Urban Planning: Scan to BIM is used to create BIM models of cities and urban areas, enabling urban planners to plan and develop urban areas more effectively.
• Maintenance engineering: Scan to BIM is used to create BIM models of buildings and infrastructure, enabling maintenance engineers to perform preventive maintenance and repairs more effectively.

Scan to BIM has many advantages over traditional BIM modeling methods, including:

• High accuracy: BIM models created from 3D scans are highly accurate, enabling engineers and architects to make more accurate decisions.
• Fast speed: 3D scanning can be done quickly, saving time and money.
• Versatility: 3D scanning can be used to scan buildings and structures of different sizes and shapes.

Some conventions about Scan To BIM products:

• Complies with LOD200
• Don’t use any materials, all use default materials
• The outer wall has an assumed thickness of 200mm

LOD 200 explained

LOD200 is a level of detail in Building Information Modeling (BIM) defined by the American Institute of Architects (AIA). Here are some key features of LOD200:

Geometry:

Components are represented by objects with approximate geometric dimensions.
The position and rotation direction of the components are relatively accurate.
The overall shape of the model is clearly shown.

Non-geometric information:

Some non-geometric information can be assigned to components, such as:
Material type
Size
Name
Describe

Granularity:

The model’s level of detail is sufficient to:
Distinguish main types of components.
Understand the overall layout of the project.
Perform preliminary volume calculations.

Solid BIM together with eRSVN provides training courses around BIM technology for individuals and businesses who want to convert from traditional methods to BIM technology.

Businesses are wondering whether to convert to BIM or not? Businesses still wondering what software is needed to switch to BIM? What’s the process like? What is the cost? How is human resources trained?

BIM training courses related to the technological process of BIM implementation using Revit, Naviswork, BIM 360, Infraworks, Civil 3D, Dynamo, Revit API, Inventor software…

Solid BIM provides two forms of online training and offline training.
