How to create the 3D model of an existing building?

As a landscape architect, or a designer, sometimes we need to have the model of the building located in, or around the site. Creating a 3D model of an existing building involves several steps in a manual manner, including data collection, modeling, and Texturing. Here’s an overview of the process:

Collect data: The first step is to gather data about the building, such as its dimensions, floor plans, elevations, and photographs. You can use various tools to collect this data, such as laser scanners, Photogrammetry, or drone surveys.

Create a base model: Once you have collected the data, you can create a base model using 3D modeling software. This model should include the basic shape and dimensions of the building.

Refine the model: Next, you can refine the model by adding more details, such as windows, doors, and textures. You can use reference photos to ensure accuracy and realism.

Add textures: Finally, you can add textures to the model to make it more realistic. This can include adding materials such as brick, concrete, and glass.

Some popular software for creating 3D models of buildings include Rhino (and VisualARQ as the architectural BIM plugin), Blender, and Revit. It’s important to note that creating a 3D model of an existing building can be a complex and time-consuming process, so it’s recommended to have some experience with 3D modeling before attempting this task. Additionally, you may need to obtain permission from the building owner before creating a 3D model of their property.

A new innovative solution

Plans 2 BIM” refers to a solution for creating a Building Information Model (BIM) from 2D plans. AI (Artificial Intelligence) is used to assist in this process by automating certain tasks and speeding up the workflow.

Here are the steps involved in using AI to create a BIM from 2D plans:

  • Data input: The first step is to input the 2D plans into the software. This can be done by scanning or digitizing the plans.
  • AI processing: The AI algorithms can be used to process the input data and extract relevant information such as the floor plan, elevations, and sections. AI can be used to recognize different elements such as walls, doors, windows, and roofs.
  • Modeling: The extracted data can then be used to create a 3D model of the building. The AI algorithms can assist in the modeling process by automatically generating walls, doors, and windows based on the extracted data.
  • Refinement: Once the model has been generated, it can be refined by adding details such as textures, materials, and finishes. AI algorithms can be used to speed up this process by automatically applying textures based on the extracted data.
  • Validation: Finally, the model can be validated to ensure that it accurately represents the original plans. AI algorithms can be used to check the model against the input data and highlight any discrepancies.
    Using AI to create a BIM from 2D plans can help save time and reduce errors. However, it’s important to note that the accuracy of the model will depend on the quality of the input data and the effectiveness of the AI algorithms used. Remember that “It’s also important to have human oversight and validation throughout the process.”
  • Import the model in your Rhino’ Lands Design project: Once you made the model with the method above, you can import it with the IFC file format and continue working with the model and the whole project in Lands Design, for a landscape design or urban design process.
