FECDS C-9 Engineering CAD & Drafting Standards Version 28 TOC PRODUCT LAYOUT REQUIREMENTS 1 INTRODUCTION 1
2、.1 A Product layout is the tool used to describe any new, revised or adapted design depicting its development of new parts and assemblies and their usage and conditions in the surrounding vehicle environment. It is comprised of components, assemblies or systems as defined by the CPSC (Corporate Prod
3、uct System Classification) codes and any other surrounding or mating CPSC systems (background) that have the potential to impact the design. Extreme care must be taken to ensure that the design is robust, functional and can be assembled. Other support types of layouts can be created such as a Stacku
4、p Layouts, Study Layouts and Installation Layouts, etc., and can be identified as to their type, for example: NEW DESIGN FOR COST EVALUATION ONLY. 2 DEFINITIONS 2.1 CAD DESIGN/VEHICLE VERIFICATION 2.1.1 The nominal and variational study, review, recording and confirmation of vehicle compatibility at
5、tributes using CAD tools and GDT, See Standard D-1. 3 REQUIREMENTS 3.1 TITLE AND REVISION BLOCKS 3.1.1 When beginning a layout, the Originator must fill in the date started along with his name in the designated spaces of the column. This is extremely important relative to patent protection. After th
6、e layout is finished, the Originator will fill in the date completed. 3.2 METHODS 3.2.1 There are many methods by which a layout may be created, modified and documented. These range from a fully electronic style with no format, to a formatted style using title blocks, revision columns which allow fo
7、r continuous update, and a Bill of Material (BOM) listing the designs part numbers and their Electronic Release Systems release dates. 3.3 LAYOUT CONSTRUCTION 3.3.1 Product Layouts are typically constructed electronically using various methods to assemble 3D Model data. See Standard G-1, page G1.1.
8、It is crucial that all data usedor referenced as background within the layout, regardless of the layout method used, reflects the latest design intent. This permits CAD Data changes to be captured and ensures that the design is kept current through all stages. Ancillary layouts that supportthe desig
9、n can be created with 2D information, for example when a Stackup Layout is needed, but does not require 3D Model data.

10、are uncontrolled.3.4 LAYOUT COMPLETENESS 3.4.1 A complete Product Layout is the confirmation that the design activity has accomplished its Engineering direction as written by the Engineering activity requesting the work. The Product Layout is also used to identify interferences, confirm clearances a
11、nd conformity with the WCR (Worldwide Customer Requirements) Standards between parts and systems that must fit and function together within the confines of the total vehicle environment. This is known as Compatibility. Sections, clearance checklists, removal studies or tolerance accumulation (stacku
12、p) computations should be used to support Compatibility. All product usages, assembly and service conditions i.e. power tools, wrenches, and part removal studies etc, must be considered within the layout. GDT on individual components, plus the affect of tolerance accumulation in assemblies must also
13、 be considered in the design as it plays a major role in its robustness and compatibility, particularly where function, plant installation and fasteners are concerned. CAD Design/Vehicle Verification is complete when these tasks have been performed. 3.5 FASTENERS 3.5.1 Utility and Standard parts, Se
14、e Standard B1, serve a critical function in the robustness of any design and must be included within all Product Layouts. Confirmation of their fit using MMC/LMC tolerance studies, and function as well as their installation must be proven within the layout using sections through attachment joints an
15、d thread length stackups to insure joint integrity. 3.6 DESIGN REVIEWS 3.6.1 Design reviews are the technique by which the contents and compatibility of the Product Layout are conveyed to the Engineering Activity who requested the work. 3.7 LAYOUT NUMBERING 3.7.1 See Standard B2. 4 SPECIFICATIONS (Reserved) 5 ADDENDUM (Reserved)
