Reverse Engineering With NX


By Joselyn Patterson. Reverse engineering provides companies with a quick and easy way to analyze data from a physical product. NX gives users a way to do that with the option to import .stl files—files typically created by scanning an object with a light scanner—into the program. Users can take a physical object and can create a model of it using a scanner.

Using a light scanner, a physical object is processed into a .stl file. Then, an engineer in the office can import the raw data into NX using a tool called Convergent Bodies. With this feature, NX directly creates a solid body model from the scan. With this new model, the user can run an FEA or CFD on the product to improve the original design.

However, the process is not so easy sometimes. When scanning, there is a possibility that the raw data can get mixed up and create a surface with holes in it. If this happens, NX can still take the scan and create a solid model with a bit of extra work. The user can take the scan and import it as an NX file instead of a Convergent Body. In this process, the user must create the surfaces by hand, stitching them together using a variety of tools such as Rapid Surfacing, Sew, and Bridges. With some additional effort, the user can still create a solid body from what was once a jumbled bunch of surfaces.

Reverse engineering is an important part of today’s tech industry. NX offers a quick and easy way to scan and then run tests on imported models with Convergent Bodies. Even if the scan did not import well from the .stl format, the user can perform additional steps to create a solid body by importing the file in the NX format. Siemens NX offers a wide variety of tools to utilize for reverse engineering.
