In today’s engineering environment, there are a plethora of design tools available. One question I often hear is “Why CATIA?” It’s a question that seems simple enough, but the answer is much more complex. CATIA generally involved a greater initial investment, but in terms of overall design cost, you may be surprised to learn that a CATIA license can be a real bargain.
Ask: “What are we trying to accomplish?”
What type of design work are you doing? Do you require the ability to create complex surfaces? Are you going to create a small number of models and small assemblies or will there be a large number of models and large assemblies? Are you sharing the models with customers or vendors? Do you start every design from scratch or reuse as much data as possible?
The list of questions above is certainly not complete, but you can see by the number of questions already posited, the answer is multifaceted.
Let’s look at the creation of complex surfaces. Many CAD systems can create surfaces of some level, but what if your company needs to create complex shapes? Look at how many CAD systems can create complex surfaces, and the list gets shorter – much shorter. Next, how many systems can modify complex surfaces? One example of this is the actual morphing of a complex surface. One might use this ability to compensate for springback in a metal stamping or counteract warpage in a plastic part. Now the list is much shorter. CATIA can easily handle these operations.
Next let’s look at large assemblies – something on the order of 500-1,000+ models. While virtually all systems can create assemblies, what happens when these assemblies get very large? Can the system handle them? How are you going to manage these assemblies? Is the system still able to operate or has its performance degraded to the point that it is virtually unusable? CATIA can handle very large assemblies, entire automobiles, aircraft, ships, etc. With CATIA V6 the management of these models is OOTB. Again the list is short at this point.
Lastly, let’s look at data reuse. […]
