NX gives you unparalleled power when it comes to working with models created using topology optimization. By combining facet, surface and solid modeling in a single integrated environment, NX eliminates the need for reverse engineering. You can simply model with the topology optimization results directly. Convergent Modeling, compared with traditional modeling techniques, is 10 times faster, and NX's convergent modeling combines traditional feature modeling with facet modeling in a single unified system.
Most models originate from CAD systems, which typically use continuous surface and edge definitions. The trouble has always been that faceted models consist of groups of polygons (often triangles), and thus, facets have customarily had to be converted into surfaces and solids to support modeling operations.
With its new convergent modeling framework, NX aims to reduce the need for this reworking by bringing the scanned data in as facets that can be worked directly in NX. There's no need to map surfaces, create solids, or do any other manual shape creation. The approach enables new additive modeling workflows such as “scan to print” and “optimize to print,” as well as extending traditional modeling workflows, all without the need for time consuming reverse engineering.
