Create a Point Cloud for Use as a Factory Asset

IMAGINiT Tricks Tutorial: Don’t waste time modeling your next factory asset — grab a camera instead.



Next, proceed to start a new project and upload the pictures. You will be notified via e-mail when the scan is complete. When your scan is finished, you can download it in various mesh and point cloud formats. For this example, we will download the RCS (ReCap Scan) file and open it with Autodesk ReCap.


Autodesk ReCap is used to clean up the point cloud scan and reorient the cloud for future use.


Autodesk ReCap

Autodesk ReCap is the tool we’ll use to interact with the point cloud scan. ReCap allows us to clean up the scan, easily removing any unnecessary points from the point cloud. In this example, the points that represent the floor were removed from the cloud. Autodesk ReCap also allows you to adjust the orientation of the cloud so the x, y, and z axes of the cloud are aligned to the machine and not arbitrarily set by the scan file.

Autodesk Inventor and Factory Design Suite

There are many methods of utilizing the point cloud in your design software. In this scenario, we will be using the point cloud to represent a factory asset. As we stated before, generating a 3D solid model of the machine will require many manual measurements and several hours of modeling time. Using the point cloud as the asset will save us quite a bit of time and will function just as well as the 3D model representing the machine and the space required for the asset.

The asset creation process starts by inserting the point cloud into an Inventor part file. The orientation of the point cloud, set in Autodesk ReCap, will be utilized when the cloud is inserted into Inventor. The original point cloud was generated in meters and needs to be scaled to the proper size. Inventor allows you to reorient the point cloud and apply the proper scale factor to the points. A single measurement of the actual machine is needed to determine the proper scale factor.


Point clouds can be oriented and scaled to suit the Inventor environment.
