An Overview of Laser Scanning for Revit Family Creation

When it comes to architectural and construction work, it is crucial to pay great attention to accuracy and staking. One of the technology trends that came into light during the development of Revit families is laser scanning for BIM creation from existing conditions. In this blog below we will discuss how laser scanning is useful in Revit family creation, the advantages and how the general process will be when utilising this technology. 

 What is Laser Scanning? 

Laser scanning or 3D laser scanning, or LiDAR stands for Light Detection and Ranging, is a process of adopting a specific distance measurement technique which involves the projection of laser beams and a process of capturing the reflected signals. The end product is a point cloud, which is essentially a geometric model of the structure made from millions of data points. In the context of Revit family creation, this point cloud data is one of the most reliable data used in the production of as-built models. 

Benefits of Laser Scanning for Revit Family Creation 

High Accuracy:

Laser scanning captures very accurate data; thus, Revit families are created in the structure with a lot of precision as per the laser-scanned structure.

Time Efficiency:

The laser scanning process can prove to be vastly more efficient than traditional measurement particularly when used in large structures.

Comprehensive Data Collection:

The laser scanning gives a finer detail when creating the Revit families because of the complexity of the architectural design.

Reduced Human Error:

Automated laser scanning decreases the likelihood of errors compared to the errors that might be obtained from standard surveys.

Workflow of Laser Scanning for Revit Family Creation

Planning and Preparation:

Planning is crucial before a laser scanning of a structure can begin. According to this, it is necessary to evaluate the site, decide upon the amount of scans, and define the most appropriate locations for scanning.

Data Collection:

With the help of 3D laser scanners point cloud is created by capturing the data points from the structure. It has to be done very cautiously to guarantee that all the area of the site is covered.

Processing the Point Cloud:

The raw data is gathered in the form of points implementing the point cloud, which can be analysed using programmes like Autodesk ReCap. The processing step removes noise from the scan, merges multiple scans, and converts the point cloud to a format that can be imported into Revit.

Importing Point Cloud into Revit:

After that, the collected point cloud is brought into Revit. The data downloaded serves as a basis for the development of Revit families.

Creating Revit Families from Point Cloud:

With a point cloud in Revit, Revit modeling tools are applied to follow and create the Revit family components. : This step involves the generation of parametric features that resemble the scanned features.

Validation and Refinement:

The last process is to reopen the point cloud in Revit and carry out the check to confirm the Revit family. Some adjustments may be needed to reach the level of detail in items that are close to the critical field.

Applications of Laser Scanning in Revit Family Creation

Laser scanning for Revit family creation is highly beneficial in various applications, including:

Renovation Projects:

Recording prevailing conditions by laser scanning helps in creating the renovation models.

Historic Preservation:

Laser scanning can capture and record the fine features of historic structures to help in the development of complicated Revit families for restoration.

Complex Structures:

In the case of buildings that are irregular or have geometries that cannot be easily described by simple shapes, laser scanning enables one to realise ideal Revit families.

Bottom line

The laser scanning process for Revit family creation is one of the most significant changes in how industry professionals engage in BIM modeling. Laser scanning advances the sizes and quality of Revit families by providing comprehensive, precise point cloud data. From new constructions to the restoration of heritage structures, this advancement happens to be one of the principal technologies involved in today’s architectural and construction industry for more accurate and trusted building information modeling.
