What are the fundamentals of point cloud to BIM?

For big construction projects, Building Information Modeling (BIM) has become a necessity. That’s why BIM course training becomes more important for construction or design engineers. Future Gen Technologies, a famous Revit training institute in Hyderabad providing BIM course training to the students and professionals and becoming the best BIM training institute in Ameerpet, Hyderabad. The course is also provided online. And Future Gen Technologies is now becoming the leading Online BIM training institute in Hyderabad.

Today, a lot of building projects like hospitals, heritage building, airports, educational institutes, universities, office buildings etc. are using BIM techniques to enable renovation, construction and spatial management of the project. The professionals how have taken BIM course training, they can only understand the concept of BIM and complete the project efficiently. From this, we can guess how vital the BIM course training is.  

The best way to manage big projects is to scan the building and use the captured information to develop BIM models. This process is called a scan to BIM. Capturing an exact point cloud model by laser survey is not totally an easy thing to do. The real challenge is taking the point cloud model as reference and developing a parametric 3-dimensional BIM model.  

• Handling the Point Cloud Model

When a survey is done by laser technique, a lot of data can be captured. It may be consisting of approximately 300 to 500 scans. In BIM course training, you learn to know how to capture the data. Like these large files require high-end processors and large storage space. That’s why Autodesk Revit is required.

Though software tools can import the whole point clouds, it is really tough to handle these within the ecosystem. So, the constructors or modelers need to recover them in parts. The experts then use the BIM course training technique like point snapping and retrace the point cloud portions with 3D components like nurbs, polygons, and surfaces. This technique is called as surface reconstruction.

• Why using the right software is more important in Point Cloud to BIM conversion?

So many software tools have used for BIM modeling, but they don’t accept point cloud data. For them, point cloud data need to be viewed separately. And 2D CAD drawings, planar projections, and orthoimages are used as a reference to build a 3D BIM model. But, now the whole process of laser scanning and deriving point clouds become pointless since the inputs are decreased to mere 2D images and displays. That’s why the right software is very much important in the point cloud to BIM conversion and the usage of the software can be known by taking BIM training institute in Ameerpet.

• Complete automation of Point Cloud to BIM conversion still needs expert intervention.

It would be fantastic if we can scan a building to build a BIM ready model. But it is not an ideal option. Because artificial intelligence has not yet developed to that extent that it can generate the thing on its own.   

When an object is scanned, the overall building and objects within the building are scanned and the objects have also their own characteristics and the information also need to be included in the BIM model. Furthermore, the objects of a building like furniture, plants, curtains etc obstruct the process of capturing complete data. In this case, the knowledge of BIM training institute in Hyderabad is required.  It requires an expert’s intervention.

Now, the point cloud to BIM has become a standard for the construction and widely used technology in the construction sectors.
