Product Announcement: Hexagon Metrology Launches PC-DMIS Reshaper

Point cloud processing software for reverse engineering and inspection help in the collection of a high amount of 3-D point data.

Published: Monday, June 8, 2009 - 10:17

(Hexagon Metrology: North Kingstown, Rhode Island) -- Wilcox Associates, a Hexagon Metrology company, announces the immediate availability of PC-DMIS Reshaper software as a standlone application. PC-DMIS Reshaper is a comprehensive 3-D point-cloud processing program that can be used to collect or import large quantities of 3-dimensional point data for manipulation and processing for downstream processes such as CAD modeling, Computer Aided Manufacturing (CAM), or rapid prototyping.   

PC-DMIS Reshaper operates as a fully functional application in an online or offline mode. Data collection can be accomplished “live” via a direct connection to a digitizing device, such as a ROMER portable measuring arm with a laser scanner, or offline via file import from more than a dozen 3-D data file formats, including STEP, IGES, ASCII, DXF, DMIS, ISO, and RAW.    

Point clouds, which can be imported with no file size or point quantity limitations, can be cleaned, merged, and edited from the streamlined user interface, and then rapidly converted into a polygon mesh model. The conversion from cloud to mesh is extremely rapid, utilizing proprietary alogorithms for polygon organization that results in highly accurate, yet lightweight file size models. Further manipulation of mesh models, including hole filling, deformation, and smoothing is rapidly accomplished with point-and-click simplicity. Final export of meshes is possible to a dozen file fomats.  

“PC-DMIS Reshaper is an excellent package for the user who wants to do a relatively discrete set of tasks, namely collection and cleanup of point clouds, and quickly getting them into a format that can be taken to the next stage in the development process. It has a short learning curve and is very intuitive to use,” says Ken Woodbine, president of Wilcox Associates Inc. “At the moment, PC-DMIS Reshaper is a standalone module, but in time, we will be incorporating elements of the technology into the core PC-DMIS product suite."   

A basic set of point cloud to CAD comparison dimensional inspection is also possible with PC-DMIS Reshaper. A point cloud can be aligned to an IGES or STEP CAD model, and deviations from nominal shown in a colored graphical “weathermap” format. This function is ideal for users who wish to compare a physical object, such as a mold cavity, to its virtual CAD counterpart. Deviations indicate areas of variation to the original model.  

PC-DMIS Reshaper software benefits functional areas such as product development, rapid prototyping, and reverse engineering, plus industries that create or use molds and dies, or produce parts with complex surfaces. Even heritage preservation can benefit from using PC-DMIS Reshaper software to collect 3-D models of priceless artifacts for archival or copy purposes.
