CATIA stands for Computer Aided Three-dimensional Interactive Application and is one of the most widely known and used software systems in the CAD world that is marketed and technically supported by IBM. The software is very intricate and is used by some of the biggest names in the business world. Currently over 20,000 companies use it worldwide and the distinguished list of names that use the software are top names such as Goodyear, Ford, Toyota, Hyundai, Boeing, Porsche, and Lear Jet just to name a few. All these top companies and more take advantage of the powerful applications that the software has to offer in order to help develop and design their products.

How to make career in Designing

If you are planning on getting into such careers as design, manufacturing, or architecture then learning CATIA software will most likely be required of you at some point in time. So how do you go about learning the ins and outs of CATIA?

There are times when a part has to be robust enough to handle several variations of design features and/or iterations. This would be the case when you build start parts or master models that give the designer a starting point for a complex design. A master model is critical if the parts you design always have the same basic features, but the details of those features vary. The most obvious case would be a plate that has variable length, width and height, as well as possibly having a few holes whose locations or sizes might change where each of the values can be driven by global parameters. What happens when you need to change the geometry of a body or feature but don’t want to have repetitive design features or you want to avoid a complex tree structure? You use a geometric parameter of course!

How to Use Geometrical Parameters

To start with, it is assumed you already have an existing part created, but do not have the ability to add much variation to that part without a considerable amount of design time or manipulation. The first thing you will need to add is a variable to trigger the change you want to create. In the example, a String parameter called “PROFILE” was created with multiple values. The different values of this parameter will determine which sketch is used to populate the curve parameter, but let’s not get too far ahead of ourselves!

Now that the trigger and the placeholder have been created, the values of the curve parameter need to be created. These values will be sketches in the screw example, but can be anything that can be described as a curve. Five sketches were created and each named according to the profile being created – Straight, Cross, Hexagon, Star and Swirl. The naming is done to make it easier to identify the profiles and I would highly recommend naming them logically, but is not necessary as each sketch has its own proprietary name by default.

The next parameter that needs to be created is a CURVE parameter. This parameter can be found near the end of the parameter list and is surrounded by the other geometric parameters including Surface, Plane, Circle, Line and Point. A geometric parameter is like any other parameter and can be thought of as an empty placeholder of a specific unit. Typically, a parameter is not very useful until it has a value specified.

In the case of a geometric parameter, the value or unit is a form of geometry; therefore a curve parameter’s value can be a sketch, spline, polyline or any other form of wireframe geometry.
