What to do with a point cloud...

What to do with a point cloud...

What to do with a point cloud...

Aside from the Reverse Engineering Add-on for ProE, is there another software package that could help me out?

I have a point cloud that I need to create solid geometry from. It is a compound curvature surface which will undoubtedly need to be smoothed and manipulated.


RE: What to do with a point cloud...


I am new to the point cloud data from white light scans. I was given a link to Polyworks Viewer 3D. I think there is a free version that can be used for visualizing the point cloud.

I would be curious to know how others are using this data. For us, we are using the data to check the shape of a die cast part. I am used to the traditional first article report with a measurement result for each dimension on the drawing. The measurements would be taken using a CMM.

With a point cloud, it is appears time-consuming to translate the results as compared to print dimensions. I am assuming that it may be better to add points to the 3D model of the part being inspected, best-fitting the cloud points taken via scanning by aligning the datums, and then checking the delta between the 3D model's points and the same locations within the cloud.

Any comments would be received with much interest.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
