General Workflow of Scan2BIM

Typically, a CAD company receives point clouds from a surveying firm that conducts on-site laser scans and registers the individual point cloud stations. At VMTS, we also receive point clouds from our partner firm. The workflow is as follows:

Common Issue: Inaccuracy of Point Clouds

We use our clients’ point cloud data to create 3D models or 2D drawings. But what happens if the scanner data isn’t precise enough? With our extensive experience, we’ve found that 80% of point cloud data contains errors. Without our custom-developed workflow and corrections, these inaccuracies would be carried over into the 3D models.

Scan2BIM Workflow

While other CAD partners may use simple workflows and draw point clouds directly in CAD programs, they often attempt to minimize inaccuracies by averaging data, hoping to reduce errors. However, in practice, this approach can lead to significant errors throughout the entire 3D model.

Advantages of Our Scan2BIM Workflow

Our workflows are more complex and sometimes more time-consuming, as illustrated in the following examples. We apply this workflow across all processes and solutions, whether it’s point clouds to Archicad, Allplan, Revit, or Vectorworks. Regardless of the software, the output quality must be consistently high. Most point cloud data contains shifts and errors. At VMTS, we detect and repair these issues before modeling the 3D BIM model. Our workflow allows us to guarantee the accuracy and precision of the data.

Conclusion/Takeaway

The accuracy of point cloud data is critical to the quality of the resulting 3D models. While simple workflows often lead to errors, our complex and meticulously developed Scan2BIM workflow offers a reliable solution for detecting and correcting data inaccuracies. This ensures that our 3D models exhibit the highest precision and quality, regardless of the software used.
