CATIA vs. Siemens Valor

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.

• 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

• VPL: component info from Siemens library server, component management.
• NPI: integration with Xpedition Designer.
• Easy to install and configure Valor.

• 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.

• Valor NPI licenses: we are working with Siemens to resolve the issue that Siemens doesn't check out the "command-line" Valor NPI Xpedition license when running Valor checking from Xpedition Designer.
• Valor Process Prep: we discovered a defect in the product. Currently waiting for a fix.
• Rule checking: Too many false positives.

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.

• 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.
