Full Hybrid Modeling

The video shows direct continuous modeling of 3D scanned faceted data in a true hybrid modeler - NX. In addition an alternative in Reverse Engineering of a scanned object is provided. Have a look and sharpen your modeling skills.

Thank you Produktdesign-Kavani-GmbH, your comment is very much appreciated and spurs me to produce more material here.

Thank you for the video. This is an excellent example of how to deal with the surface bodies, and what functions of nx to use. I never used unsew function, I always used offset surface, value 0, to get the copy of the surface. What does the Cleanup facet body do? In which situation or on what facet bodies it is useful?

[@fredriksandblom27]

Hi Edvinas V, thank you for your reply and the recognition here its a boost to continue providing solutions here. To you questions.
1. Unsew has been around for a couple of releases and is really handy to separate an area from a sheet or solid body for various purposes. Just to highlight, it is not a copy but the actual same faces that originates form the original body but in unsew'n state can be handled separate form the original body and support various worklflows and when done can be sewn back into the original body.
2. The bodies in the video; one traditional Solid Body (the green pipe) and one Convergent Body or facet body (bright blue). The convergent body is a body that is defined by a "cloud" of triangular planar faces. This is often resulting bodies from e.g a 3D scan of some sort. These bodies are not parametric nor mathematically defined (coordinates only). NX provides great strength in its Full Hybrid Modeling capabilities as these Convergent bodies can be mixed together with traditional sculpting and parametric molding - Surface and Solid modeling. This means that you do not necessarily need to reverse engineer e.g a scan of an object and redefine areas as analytic shapes to use them in your digital definition and manufacturing processes, you can leave them as Convergent Bodies (facet bodies) and include them in you workflows directly. Many of the traditional features also work directly together with the Convergent Bodies and there is no need to reverse engineer whole scans you can settle for a limited area and sometimes you don’t have to do anything - just use the Convergent Bodies directly in your workflow - as can be seen in the video. Extremely powerful and enables unlimited workflows. Now the Cleanup is a function that I highly recommend to always start of with as this will optimize the facet body input. If the body originates form a scan or another system there might be some quality issues where you e,g have Degenerated Edges, Folded Edges, Self-Intersections, Inconsistent Normal’s or Laminar Slits - The Cleanup Facet Bodies helps eliminate all these quality issues and in doing so ensures eliminating downstream issues before they become issues on e.g. imported STL’s from other systems or Scans.
Best Regards
Fred

@@fredriksandblom27 Thanks for the explanation, appreciated! I just received the training to use the ATOS 3D scanner, so all of this is very relevant to me.

@@pino32wn, great scanner you've got there. Are you going to use it for reverse engineering, repairs quality validation or others?

@@fredriksandblom27 We are using it for many tasks, for running production to check and track critical dimensions, for the PPAP parts, and for R&D purposes. Planning to use it for making some esthetical parts from modeling clay, scan them, and do reverse engineering.
