1. Point cloud modeling: How to utilize scanned data in
Revit?
Point cloud modeling is quite a new concept in Architectural, Engineering and Construction
industry but irrespective of its being new or old, it has transformed the entire reverse engineering
process. When it comes to renovating an old building, point cloud modeling remains at the heart
of entire renovation process as it empowers design and construction professionals in obtaining
information concerning physical and functional characteristics of the existing structure. In short
point cloud modeling is quintessential for AEC professionals for perceiving the geometrical
composition of existing building so that the process of renovation can be carried out swiftly.
Point cloud modeling can be defined as a process of developing 3D models by utilizing the
scanned data that is acquired by AEC professionals after scanning the existing structure with
high end laser scanners.
Tips for utilizing scanned data in Revit
 Building data concerning as-built structure is first obtained in raw format which needs
indexing and scaling before it could be used in Revit project.
 Hence BIM modelers are required to index the laser scanned data in the first place.
 Once the laser scanned data in the raw format is effectively indexed by BIM modelers it
then becomes utilizable in Revit.
 What BIM modelers do is, they convert the raw scanned data into .rcp and .rcs file
formats which can be constructively utilized by them in Revit projects for developing 3D
models.
 When linking point cloud data into Revit, it is required to select an indexed point cloud
file which is available to modelers with .rcp extension.
 Briefly, .rcp file stands for Reality Capture Project file whereas .rcs file stands for Reality
Capture Scan file.
 Another important thing is that, .rcp file is a collection of umpteen .rcs files, so on the
basis of project requirement modelers link either .rcp file or .rcs file in the project.
 Apart from this, modelers are also required to effectively position point cloud files in
Revit project so that point clouds can be efficiently visualized by them and for doing so
they are required to effectively select a positioning option within Revit.
 All together there are four options that are available to users (Auto-Center to Center,
Auto-Origin to Origin, Auto- By Shared Coordinates and Auto-Origin to Last Placed)
which can be used by them for positioning point cloud files in Revit.
Point cloud data can be effectively utilized by users if the above points are taken seriously by
them.
