CATIA vs. National Instruments LabVIEW

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.

Most of the time, I am using LabVIEW to develop automated controls for lab-scale and pilot-scale systems. LabVIEW is great for its graphical programming interface, which is easy to learn and understand. The program also has a lot of built-in VIs to perform different complicated I/O, data processing, controls, and graphing tasks which are extremely useful and convenient to use. My only problem with LabVIEW is how hard it is to clean up and debug the program, due to its being a graphical interface. It is hard to search for specific variables when debugging, and some of the online debugging features don't function well in real-time.

• 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.

Incentivized

• real-time data visualization
• implementation of modern control strategies
• integration of languages such as python and c++, for various applications
• data acquisition through microcontroller cards

• 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

• Barrier to entry is large
• Install times are crazy
• Just in time help needs to be more apparent (most students do not know about the examples section)

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

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.

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.

We have used MatLab's data acquisition toolbox in the past which was not too bad either, especially if you prefer the text-based programming format. The only problem with that was that the library of compatible data acquisition hardware was somewhat limited and if your hardware is not from one of the more popular brands like NI there is a good possibility that you won't be able to use it with your MatLab script. LAstly, the amount of supporting material (tutorials, etc.) is very limited as it is not a very popular tool

• 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.

Incentivized

• We are able to save money by writing our own programs instead of outsourcing.
• We recently bought a new force test stand and we are able to use LabVIEW to write a program that fits our needs exactly instead of making due with what came with the stand.
• When our customers ask us to do data acquisition, we know that we can always make a solution.
