BIM Viewer Section Analysis

The “Section Analysis” feature in BIM Viewer is an incredibly useful tool for architectural, engineering and construction professionals. This feature allows users to visualize and analyze specific sections of a BIM model in a detailed and accurate manner.

Here I explain how it works and what its main benefits are:

What is Section Analysis?

Section Analysis, also known as section cutting or sectioning, is a functionality that allows you to virtually cut the model into one or more planes.

This makes it possible to visualize the interiors of the model, offering a perspective that could not otherwise be obtained without a physical model or disassembly of the digital design.

Features and Benefits of Section Analysis in BIM Viewer

  1. Detailed Viewing: With section analysis, users can “cut away” parts of the building to examine its internal structure. This is particularly useful for reviewing hidden infrastructure details, such as plumbing, HVAC systems, and structural elements.
  2. Analysis and Diagnosis: Allows engineers and architects to identify and resolve potential problems in the early phases of design and construction. For example, they can detect interference between different technical building systems, such as collisions between air ducts and structural beams.
  3. Facilitates Collaboration: By being able to share specific views of sections with the team or stakeholders, communication and decision making is improved, ensuring that everyone involved understands the critical aspects of the project.
  4. View Customization: Users can select exactly how and where they want the cutting plane to pass through the model, allowing views to be completely customized to the specific needs of the analysis or presentation.
  5. Integration with Other Tools: Section Analysis can be used in conjunction with other BIM Viewer tools, such as annotations and measurements, to provide additional context and precise data about specific areas of the model.
  6. Education and Training: Allows educators to visually show how different components of a building interact, improving student learning and understanding.

How to Use Section Analysis in BIM Viewer

To use this feature, simply select the Section Analysis tool in the BIM Viewer interface. You can then define the cutting plane or planes by dragging the sliders or entering specific coordinates.

The model will update in real time, showing the cross section. Additionally, it is possible to manipulate the visibility of different components to further focus on specific areas of the model.

It is ideal for reviewing installations, verifying structural elements or simply gaining a better understanding of the interior design of a project.

Step 1: Access the Section Analysis Tool

  • Enter BIM Viewer.
  • Open the project and model you want to work on.
  • In the toolbar, look for the icon that represents Section Analysis (usually represented by a cutting plane icon) and click on it.

Step 2: Add Plane X

  • When you activate the Section Analysis tool, you will see options to add planes in the X, Y and Z axes.
  • Click “Add X Plane”. This will insert a vertical cutting plane that you can move along the X axis.
  • Use the slider or enter a specific value to adjust the position of the plane and watch the model view update in real time.

Step 3: Add Plane Y

  • Click “Add Y Plane” to insert another vertical cutting plane, but oriented perpendicular to the X Plane and moveable along the Y axis.
  • Adjust the position of the Y plane similarly, using the slider or entering a specific value.

Step 4: Add Z Plane

  • Selecting “Add Z Plane” will add a horizontal cutting plane that can be moved along the Z axis.
  • This plane is useful for viewing cross sections of the model from a top or bottom perspective.
  • Adjust the Z plane with its corresponding slider to obtain the desired section.

Step 5: Add Frame

  • The “Add Box” option allows you to establish a three-dimensional section area restricted to a user-defined cube or box.
  • By selecting this option, you can define the dimensions and position of the box, which will restrict the display to this specific area.
  • This is particularly useful for isolating and examining a very specific part of the model without distractions from other elements.

Step 6: Manipulation and Analysis

  • With cutting planes defined, manipulate the view by rotating, zooming, and panning the model to examine necessary details.
  • Use BIM Viewer’s additional tools, such as measurement and annotation, to perform more detailed analysis or document important findings.

The Section Analysis feature is an invaluable feature in BIM Viewer that significantly improves the ability to inspect and analyze BIM models in depth.

By following this tutorial, you will be able to make the most of this tool, facilitating better understanding and collaboration in your construction and design projects.
