Siemens NX Engineering Services in Practice
NX engineering services are engineering tasks done in Siemens NX by an external team: CAD design, MBD and PMI, CAM postprocessors, NX migration, process optimization and NXOpen automation. inteliScience delivers them with employed NX engineers in Cluj-Napoca, under a service contract and led by our own project lead.
In practice, the work arrives as defined packages: a set of parts and assemblies to model, a drawing set to derive or convert to MBD, a postprocessor for a new machine, legacy data to migrate, or an NXOpen tool that removes a repetitive step. We work in your NX version and to your templates, naming conventions and release rules, and every delivery is reviewed internally before it reaches you.
Each service in detail: Siemens NX training, MBD consulting, NX postprocessor development, engineering process optimization, Siemens NX migration and NXOpen developers on demand. First steps: free NX potential check or NX engineering assessment.
What the services cover:
- CAD design to your standards: parts, assemblies and drawings in your NX version, with your templates, reference sets, layers and naming rules.
- MBD and PMI: product and manufacturing information on the 3D model to ISO GPS or ASME Y14.5, as a step from drawing-based processes towards model-based definition.
- CAM postprocessors: postprocessors for your machines and controllers, built new or adapted, and tested against your reference programs.
- NX migration: moving to a new NX release or from another CAD system, including data conversion, rebuilding of key models and checks of the results.
- Process optimization: a review of how a part moves from design to drawing, release and manufacturing, with concrete changes to templates, standards and tools.
- NXOpen tools: automation of repetitive steps such as drawing creation, attribute filling, batch export or model checks, delivered as working tools in your NX environment.
How a request runs: you describe the task and send your standards and sample data. Our project lead agrees the scope with you, assigns the work to our NX engineers and stays your contact throughout, and you review and release each delivery. AI for Siemens NX, such as assistants and drawing automation, is a separate offering.
FAQEverything you need to know
Siemens NX engineering services are engineering tasks that an external provider carries out in Siemens NX for a manufacturer: CAD design, drawings and MBD/PMI, CAM postprocessors, migration of NX data and NXOpen automation. The client defines the task and releases the result. inteliScience delivers these services with NX engineers employed in Cluj-Napoca, under a service contract with day rates or as agreed work packages.
PMI (product and manufacturing information) are the annotations on the 3D model in Siemens NX: dimensions, dimensional and geometric tolerances, surface finish and notes. MBD (model-based definition) is the approach of using that annotated 3D model instead of a 2D drawing as the authoritative source for manufacturing and inspection. Our engineers add PMI to ISO GPS or ASME Y14.5, as your company specifies, and help move drawing-based processes towards MBD step by step.
An NX CAM postprocessor translates the tool paths created in Siemens NX CAM into NC code that a specific machine and controller can run. It needs to be adapted when a new machine, controller or kinematics is introduced, when NC programs have to be edited by hand after posting, or when moving from Post Builder to Post Configurator. Our engineers build and adapt postprocessors and test them against your reference programs before they are used on the machine.
Typical candidates are steps that engineers repeat with the same rules: creating and updating drawings, filling attributes and title blocks, exporting STEP, PDF or JT files in batches, checking models against company standards and generating variants of parametric parts. NXOpen is the Siemens NX programming interface for Python, C#, C++ and Java that makes this possible. Our engineers write such tools for your NX version and put them into operation in your environment.
An external NX engineer needs the NX version and templates you use, your CAD and drawing standards, the input data such as sketches, previous parts or customer specifications, and clear acceptance criteria for the result. Access to Teamcenter or another PDM system is optional, because many tasks start with an exchange of native NX files. At inteliScience our project lead collects this in a short kickoff and confirms the scope in writing before work starts.
Usually in one of two ways: by day rate for work whose scope changes over time, or as a fixed price for a clearly defined work package such as a drawing set or a postprocessor. Many companies start with a small, clearly defined package to test quality and communication. inteliScience works under a service contract with day rates or agreed work packages, and the quote follows a short scoping call.
