Concept's
The integration and concept level is devided into two steps.
1. The methods of concept work
We consider the Sketcher to be the basic tool in the concept work, because it represents the best possibility to transport data and knowledge within a CATPart or to pass these data with link to external parts.
If we take a closer look at the Sketcher, we will recognize that the large number of elements contained in a sketch is bundled. This means that after having left the Sketcher, only the sketch as one object and its support (a face of an axis system) are visible in 3D respectively in the „Specification tree“. This sketch is treated as selection object and can be used e.g. for the creation of surfaces or solids.
Furthermore, we have the possibility to extract sub-elements of the sketch (e.g. with the function „Extract“) and to use them for the creation of surfaces or to generate further wireframe geometry like „Projections“ or „Intersections“. Besides, a sketch is not fixed on one reference element, its position can be changed. Nevertheless, its content stays the same, the sketch remains correctly aligned, but its further use can absolutely differ. In the following chapters treating the sections we will get to know additional advantages of the Sketcher!
In order to position 3D elements like „sketches“, „UDF’s“ and „Powercopies“, we use axis systems. We design these axis systems associatively, so that if their position changes, all depending elements will be modified as well. When we generate drawings respectively views, we will refer to these axis systems, too.
When we later on use concept models in product structures as basis for the positioning of components, we can employ axis systems as well.
2. The working environment in the concept work
Due to the fact that the concept work for a vehicle is not carried out by one single person, but by several designers or teams, we need a special working environment in order to be able to display a certain cross-communication. For the representation of this working environment, speak cross-communication, we introduce the so-called „Working model“. It summarizes designs sections, neighbouring geometry, concept and detailing models.
The working model is a product structure in CATIA V5, speak a CATProduct. In the following the contents of the working model and their roles will be listed.
