New CAD/Point Cloud Comparison Tool Lines Up

Working together, DotProduct and Assemble Systems have made it possible for users to register and compare a site’s pointcloud data with its BIM model while still on-site.
DotProduct is well-known for its 3D data capture solutions, and Assemble provides a software as a service (SaaS) platform that helps construction companies manage CAD and building information modeling (BIM) data. The companies have now linked Dot Product’s Dot3D Edit point cloud viewing software to the Assemble server, allowing users to download CAD files into Dot3D for easy comparison.
On June 5, at SPAR 3D 2018, the two companies demonstrated their collaboration for the first time by performing a pipe spool quality assurance test.
They used the point cloud data of a pipe, captured on DotProduct’s DPI-8X scanner, and imported the data into Dot3D Edit. After cropping out all the surrounding data (anything that wasn’t part of the pipe), they imported the CAD file of the project from the Assemble cloud server. They then aligned the point cloud model with the CAD model, and let the software automatically find (and color-code) any differences between the two models.
