Aiming to enhance the continuity of the design information flow and facilitate the knowledge reuse, this paper makes use of a knowledge-based framework to integrate conceptual design tools: Quality Function Deployment (QFD), Axiomatic Design (AD), Failure Mode and Effects Analysis (FMEA) and the MOKA methodology into CATIA v5 system. There is also a lack of knowledge reuse in routine design process, resulting in large cost-waste of the overall design process. This situation causes the discontinuity in the overall design information flow: Customer Needs (CNs) - Functional Requirements (FRs) – Design Parameters (DPs) – Key Characteristics (KCs) – Geometric Parameters (GPs). This paper presents some theoretical aspects regarding the design process of products including surfaces and a few case studies showing the many possibilities in creating complex surfaces using the CATIA v5 software.Ībstract: The design process comprises the Conceptual Phase, the Embodiment Phase and the Detail Design Phase in which commercial PLM/CAD systems mainly support the latter ones. However, the 3D virtual model is accompanied by its mathematical description, parameters, restraints and these eliminates the need of measurements for prototyping or mass production, can be modified at any modeling phase, can be tested in various ways etc., which is a major disadvantage of using a physical part. The virtual model may look the same as the real physical model, but it’s intangible. Using such a system, the engineer models, adds, deforms and edits parts in the process of detailing a shape. Geometric modeling systems provide a virtual environment similar to the real one in which the physical model is constructed/designed and manipulated. In this exercise you will design the shape of a Perfume bottle.Abstract: The goal of the CAD parametric modeling is to create a 3D representation, flexible and complex enough to encourage the engineer to easily consider a variety of designs with the cost of applying changes as low as possible.

Master Exercise Presentation: Perfume BottleMaster Exercise Step (1): Creating the Main ShapeMaster Exercise Step (2): Splitting the ShapeMaster Exercise Step (3): Creating the NozzleMaster Exercise Step (4): Finishing the Perfume Bottle Master Exercise: Perfume BottleYou will complete the master exercise by performing following steps. Move your mouse to highlight the arc circle of the compassĬlick and drag the mouse to deform the shape and obtain a shape close to a circle Select the surface and select the top edges to insert two sections Select the correct view to see the circular face Re-do the operation until the torus is closedĬreate a cylinder (see corresponding section) Press Ctrl key and select those two edges Press the control key and drag the compass to reduce the size of the face Select two opposite surfaces (use Ctrl key) If necessary, select all the edges of the closed surface with the triggers square selection mode option or using Shift Trap You will start with a standard closed surface and deform it to get the final shape. In this step you will create some basic geometrical shapes.
