Home » NX vs SolidWorks

Mechanical Computer-aided Design (MCAD) tools are essential for any organization that designs and manufactures physical items today. Siemens NX vs Solidworks compares the most extensively used applications for high-volume consumer items. Choosing which is the best is always difficult because each has its own set of distinguishing traits. While some people prefer Solidworks for its ease of use, others believe Siemens NX is a better fit for their needs. Both can assist design engineers in efficiently modelling complex geometries and combining their modules or features to extend the design for other departments.



When United Computing, Inc. first launched, NX was known as Unigraphics. It is a high-end product since it provides complex and tightly integrated product development solutions for CAD, CAM, or CAE applications. Yet, the word can still be used when referring to pricing because NX is an expensive program. NX, like its competitors, provides drafting, assembling, designing, and modelling capabilities, but users see it as the best in its class due to its ease of use. Its user experience and interface are so advanced that they offer adaptive capabilities, tracking and learning the user’s actions, and frequently used features to forecast the commands they will use throughout future projects. Because of these elements of its UI and UX, learning NX is likely easier than learning Solidworks. Even so, a newbie would have considerable trouble. NX is excellent for developing 2D and 3D designs of complicated parts and systems. 

It can also be used for parametric modelling, solid modelling, sheet modelling, aerodynamic modelling, and surface modelling, among other things. Notably, when working with NX’s sheet metal environment, you are less likely to discover problems than when using other CAD software applications, making it the go-to tool for sheet metal modelling. 

Furthermore, it provides the most excellent rendering in its class, with no other CAD software coming close. Some of the rendering feature’s capabilities include assigning material and colour to each part and surface in an assembly, making it easier to identify one from another. The single disadvantage of its rendering is that it takes excessive time, even when the image resolution is stable.


SolidWorks is Dassault’s most well-known 3D design solution for industrial and mechanical models. It is a 3D industry market leader. It is a computer-aided design (CAD) and computer-aided engineering (CAE) program for professionals. Users can use Solidworks to construct mechanical parts, complex machinery assemblies, and welding structures, among other things. As the name implies, SolidWorks is a solid modelling application. Users of SolidWorks can create models, components, and assemblies utilizing a parametric function-based approach. SolidWorks models often begin with a 2D drawing, after which users utilize some SolidWorks tools to extrude them into 3D designs.

SolidWorks is a software package that includes many professional-grade tools for the various stages of product development. 3D CAD, simulation, visualization, electrical design, collaboration, product data management, product configuration, and technical communication are the features of SolidWorks. SolidWorks’ simple 3D design and modelling features enable you to develop, produce, validate, and translate your ideas into product designs. With parametric modelling, you can create 3D models from 2D sketches. SolidWorks has the tools you need to create a part, an assembly, or a working drawing, no matter how complex the design.

NX vs SolidWorks

Preference factors such as user experience, familiarity, and user’s company preference usually influence the decision between NX vs SolidWorks, which are two industry-leading and competitive CAD software packages. However, each program has identical capabilities and features, and both are perfectly adequate for seeing a project through from start to finish. So, what’s the distinction between these two software packages?

NX vs SolidWorks: Similarities in Functions and Features

  1. 3D mesh modelling: Users can now automatically turn 2D textures into 3D geometry. Not to mention the ability to model in a single process and save time with the added convenience of a bi-directional viewpoint.
  2. Updates to the touch user interface: During sketching, users may write dimensions directly on drawings, eliminating the need to switch between the keyboard and touch screen.
  3. CAM enhancements: Both programs enable CAM users to accelerate their design and production processes. One example is the zigzag mode for high-speed milling, allowing users to remove material significantly faster.
  4. Smart manufacturing: SolidWorks and NX allow you to use one file to store all the essential data sets of a project, making model-based definitions easy to find. No matter what stage you’re at—from conception to simulation to production—both applications will store all the information you need in a single spot.

NX vs SolidWorks: Differences in Functions and Features

  1. Feature Tree

NX and Solidworks both employ feature trees. Yet, the NX feature tree is infinitely more powerful since, if desired, you may entirely bypass it using direct editing tools. Siemens has numerous patents for these tools, which is why you rarely see them elsewhere. Solidworks has a pitifully limited number of them, namely “move face” and “remove face,” which it had to license from Siemens to include. In contrast, NX has dozens of these tools, each more powerful than before.

  1. Convert Entity

A sketch defines everything in SolidWorks. To use existing geometry, you must first build a sketch, then turn an entity into a sketch line or point. Then you may give these drawing objects features. In contrast, in NX, you do not need to produce a sketch to reference an element. Instead, click on existing lines, points, or creatures within the feature dialogue to rapidly and strongly build geometry. Also, it’s smarter, faster, and utilizes fewer clicks and features.

It’s difficult to properly appreciate this strength if you’re still stuck in the SolidWorks paradigm, but it’s unforgettable and irreplaceable once you get acclimated to it.

NX vs SolidWorks: Areas of Application or specific users 

NX is a CAD program suite that includes CAD, CAM, and CAE solutions. Professionals from various industries utilize the program for their goods because of its multidisciplinary features and functions. Transportation, automotive, aerospace, construction, and manufacturing are examples of sectors. For instance, Sterling Engineering, Inc., CEG Partners, Boeing, and Virgin Orbit are companies that use NX in their production. 

Various sectors and professions use Solidworks due to its wealth of relevant tools and capabilities. Engineers who design goods for a variety of industries are the key users. Defence, aerospace, automotive, agricultural, manufacturing, construction, oil & gas, and robotics are among these industries. In addition, electrical engineers and technicians can use the program to precisely construct and analyze complex electrical circuits.


The comparison of NX vs SolidWorks depends on your intentions for using the software. NX and SolidWorks are both widely used, industry-leading, and recognized software for product design, development, and manufacturing. In addition, their workbenches provide integrated solutions for CAD, manufacturing, and engineering.
