Why NX as a Technology Platform?

NX is built on the most modern architecture of any major CAD/CAM/CAE solution

Every NX release is customer deployment ready

NX is an open solution that “plugs and plays” with your existing IT systems

NX enables you to use data from previous NX and Unigraphics releases in the current release

Goes back to the first Unigraphics release (circa 1984)

Data �Preservation

Proven Deployment

Scalable

Platform�Flexibility

NX takes your innovation to the next level by removing technology barriers by…

Deploy ability, With NX you do not have to wait to take advantage of the latest advancements in CAD. NX is being deployed at the largest engineering enterprises in the world right after it is released.

Data Preservation is a hallmark of NX. NX will never force you to leave your data behind to move on the next release. We have always prided our self's on the ability to use all the data we have created no matter the platform of the past release.

Open Technology is our realistic approach to solving your engineering and design problems. Siemen PLM does supply a complete suite of software to address the needs of the enterprise, but we do realize that you may want to bring in another software solution. With our open technology paradigm we have the ability to make this work in your enterprise.

Key benefits of NX Reverse Engineering

Single, integrated, end-to-end workflow support from scan data handling and CAD reconstruction to simulation, validation, and manufacturing.
NX Convergent Modeling allows companies to work directly with scan data without the need for reverse engineering.
Full reverse engineering workflow support within a robust, parametric modeling system offers significant productivity gains over competitive software.

Scan data cleanup, preparation, and evaluation with NX Convergent Modeling^TM

Import scan-line points or scanned point clouds as facetted mesh data. Various methods can be used to analyze data quality including: Evaluation of shape (curvature, analytics), Reflections, Draft, and Sections. Scan information can also be analyzed such as cloud density. Visualization of points and facets is also possible.
Cleanup facetted point cloud data including: Snipping, Hole Filling, Smoothing, Remeshing, Decimation, and Subdivision.
This process is very dynamic and visual in NX.

Data cleanup and preparation increases the value of using scan data directly in downstream workflows, decreasing design time.

Direct use of scan data with Convergent Modeling^TM

Work directly with scan / mesh data as native CAD geometry, virtually eliminating the need for reverse engineering in certain workflows

Feature based parametric modeling with mesh geometry – Booleans, Fillets, Chamfer, Drafts
Direct use in downstream workflows – Assembly context, Documentation, Tooling Design, FE Analysis, NC and Additive Manufacturing

Seamless reuse of mesh geometry as a first class citizen in CAD can greatly speeds up the design process

Comparison of as scanned to as modeled with NX Analyze Shape

Register (align) scan to CAD. NX provides tools such as general transformation and scaling, multi-mesh alignment, matched point set alignment, and best fit alignment.
Measurement and deviation gauge inspection tools provide the ability to measure differences between the CAD solid and the scan.

Integrated inspection ensures the design is meeting product quality standards throughout each stage of the process
