CATIA vs. NX CAD

CATIA is probably the most preferred 3D modeling tool in the automotive and aerospace industries. This specific surface (it can be handled well by the experienced users) is well suited to use parametric design principles and hence result in great products. One of the issues we have in the automotive industry is to work with large surfaces for body exterior (main body, gate, hood.) or interior trim (door, headliner.) panels. CATIA enable us to design surface perfectly through the lines. Also, assembly features for intricate designs (gearbox, exhaust, engine, suspension.) are more than adequate. I did not find any inefficiency while designing products with CATIA. Only the interface and handling of the menu and mouse is not the best - or at least you need time to get used to it.

NX CAD is very good when it comes to three dimensional modelling and rendering and visualization. Furthermore, the export to jt function together with import into other Siemens software packages, such as Teamcenter, is a major reason why I am using NX. However, it can be a little more computationally expensive compare to other CAD packages.

• There really is no 3D software that offers all the design modules, drafting and assembly options and manipulation tools that CATIA offers.
• There are a specific module and tool for just about anything you need to do, so the design process with CATIA can be very optimized.
• Great surface modeling capabilities.

• Seamless interaction across multiple departments.
• The software allows you to create a very high level of control and organization within your engineering staff. This reduces the companies mistakes and maximizes productivity.
• The software makes it very easy to track your product through every phase of the production cycle.

• Updating an existing design can become really frustrating. You have to reassign all the radiuses, for example, even if they moved slightly.
• CAE function is not that good.
• Radiuses are slightly bad and can cause you lots of problems.

Incentivized

• Keeping the colors of surfaces if volume bodies are linked
• Show and keep symbolic threads
• For me, I miss more information why a surface can't be deleted or a radius is not possible. And maybe a solution, how could it look like, if NX CAD adds a new surface.

It works very well for our organization. It has made us much more productive.

It is a good software for conception. But it is too hard sometimes to work with and understand the different options available

Siemens NX CAD has been has been simple in design & user interface. It is best among the competitors. It can develop heavy models & designs with very ease. It has Layers options for arranging multiple assemblies in the same file. It does not require heavy system investment & works fine on professional PCs

I generally contact with IT or internal CATIA support team, so I cannot comment in detail. I remember we have struggled to move to v6 update, and it required a long and detailed work to update all the systems. There were some times we had limited support from Dassault, but it is normal for a company of our size. So I cannot criticize much.

NX CAD version is going out of support after only 12 months. Changes will not be implemented after 12 months from prodcution

Once major advantage I realized when using CATIA is surface modelling, and modifications or changes in part model later. SOLIDWORKS provide a really good and quick way to part modelling. However, part modifications and assembly modifications take time. In CATIA, complex geometries can be easily generated, when compared to SOLIDWORKS. Managing and updating designs of large scale models and complex geometries made me realize an advantage of CATIA over other CAD software.

I like NX CAD modelling features and drafting tool bars which helps in accomplishing the task in minimum steps. The available tools precisely generate the splines and complex geometries as required. There is perfect integration between NX CAD and NX CAM modules with less data loss. Better graphical interface and simplified commands makes NX CAD a better software then others.

• The ease of modeling helps a lot to save time, in both modeling new parts and also assemblies, which in the end makes a great positive impact on the development.

• Through API implementation we have created some CAD Automation tool that saved us about 100h to create specific 3D geometry
• Teamcenter integration leverage quality of 3D geometry because avoid any situation of duplicated version of same Item that can take lot of hours to verify the correct version
• Possibility to integrate different 3D format allow to earlier detect possible impact of wrong geometry
