4 Introduction project GPS - capabilities of CAD systems Reason: Extensive changes in the field of geometric product specifications (GPS, ISO / TC213) Current standards contain changed and new description options for dimensions, tolerance specifications and systems The methods for applying the rules of GPS during the Modeling and construction are neither available nor described. Goal: Elaboration of a statement on the basic capabilities of the CAD systems in connection with the geometric product specification. The project is to analyze the basic capabilities of the CAD systems to be able to deal with the specifications of the GPS standardization. The proof of capability and the developed methods form a basis for the introduction / implementation of GPS in the ZF DTDE14, GPS requirements for the CAD systems

5 Introduction The following use cases describe the most important specifications. The specifications are essentially specifications from the geometric tolerancing (ISO1101), dimensional tolerancing (ISO14405) and the general references (ISO5459) The implementation of the use cases are checked with the strategic CAD systems in ZF to determine the extent to which these requirements can be mapped. Creo and Catia are considered to be strategic CAD systems. Modules such as the GD&T (CreoAddon) and FTA (Catiamodul) are included. The implementation of the GPS specification in CAD can be viewed in both 2D and 3D. The focus of the observation should be 3D (3D master model). The priority or importance was generally assessed for the use cases, as were the calls (1 [very important] to 3 [less important]) DTDE14, GPS requirements for the CAD systems

13 UC-GTol-RestrArea Restricted tolerance areas The limited area is to be defined as follows: By its limitation, which is indicated by a broad dash-dotted line (long dash) and its position and dimensions are to be defined by TED by its corner points, which are indicated by crosses the integral geometry element (the locations of the points are defined by theoretically exact dimensions), denoted by capital letters and lines ending with an arrow. The reference line, which begins at the reference line, which is connected with the specification of the geometric tolerance, must end in the limited area DTDE14, GPS - requirement for the CAD systems

14 UC-GTol-RestrArea: Creo4 Feasibility in Creo4: Fig. 1 Comment: Representation in 3D and 2D possible The area must be defined from a sketch using the designated area. Hatching is only possible with an additional cosmetic sketch. If an offset line of the area is shown in the drawing view (Figure 1), the offset line must be added manually.

15 UC-GTol-UZ Offset tolerance zone (UZ) The extracted surface must lie between two equally spaced surfaces that enclose spheres with a defined diameter equal to the tolerance value. Their center points are in turn on a surface that corresponds to the envelope surface on a sphere that is in contact with the TEF, and the diameter of which is equal to the value given after UZ. The direction of the offset is indicated by the sign, with the + sign indicating outside of the material and the - sign indicating within the material. The sign for the offset must always be specified. To be clarified Representation in CAD DTDE14, GPS - requirements for the CAD systems

21 UC-GTol-Ind indicators The cutting plane indicator (b) must be entered to the right of the tolerance indicator (a). The cutting plane indicator must have a reference letter in the second field. A symbol is entered in the first field that indicates how the cutting plane is related to the reference (parallel, right-angled, at a certain angle or symmetrical). The reference associated with the reference letter allows the cutting plane to be built up in accordance with the specified symbol. The reference is defined by the reference geometry element identified by the reference element indicator (c). The orientation level must be specified by an orientation level indicator, which is attached to the right of the tolerance indicator as an extension. DTDE14, GPS - requirements for the CAD systems

50 Agenda Introduction Use case Conclusion / recommendation DTDE14, GPS requirements for the CAD systems

51 Conclusion The GPS capabilities of the CAD systems show clear progress both in Catia (here V5 / 6 R2016: FTA) and in Creo4 in the latest versions (latest CATIA version: V5 / 6 R2017). Dimensional tolerances are only insufficiently supported in CAD. A representation is often only textual and has no function. The tested CAD systems, Catia V5-6 R2016 and Creo4, are still behind the latest requirements of the use case in some areas. This has the following reasons: The use case is based on the ISO 5459/1101 standard from 2011, as well as the provisional standards from The standard served as the basis for Creo4 (Catia R2016). The provisional standards (2016) were only partially taken into account. As a result, requirements are not fully supported in the latest standard. Vendors adapt to the standards, not the other way around. The CAD systems will generally lag behind the standards DTDE14, GPS - requirements for the CAD systems

52 Recommendation Even if the CAD functionality is between 70-80% at the current level of the standard, implementation is possible. We do not recommend a comprehensive, but an introduction based on a suitable pilot. This pilot should start in a selected specialist area, preferably with a new project. On the basis of the pilot's experience, further steps can then be taken to introduce a broader spectrum. The introduction of the GPS standards is not just about a new CAD methodology. Follow-up processes are also affected and should be considered in this context DTDE14, GPS - requirements for the CAD systems
