First and second auxiliary views. Basic descriptive geometry. Section views, types, hatching conventions. Basic dimensioning requirements. Tolerance for fits and geometry control. Detail drawings and assembly drawings, other drawings and documents used in an engineering organization. Bill of materials. Fasteners and welds. Design process and methods. Project management & teamwork. Requirements and function analysis in design. Conceptual design and testing. Concept evaluation design factors such as: cost, quality, manufacturability, safety, etc. Systems modelling & design detail.
Subject outline
BS-15 Engineering Graphics and Design Process is a Basic Studies technical exam (PEO National Examination 04-BS-15) on engineering drawing conventions and the design process: choosing and placing orthographic views in third-angle projection, line types, dimensioning to professional standards, section views, isometric sketching, limits, fits and tolerances, feature-based solid modelling, manufacturing methods and design for manufacture, analysis and testing, and needs, specifications and the design process itself.
The paper is 3 hours and closed book with no calculator. All sketches must be made freehand — straightedges may not be used — and every question must be attempted: the exam is out of 100 marks with no choice of questions.
What this course gives you
Worked answers — all eleven questions from May 2019 and December 2019, answered in full: which views to choose and why, how to place and dimension them, the modelling sequence with the reasoning behind the order, and the written questions argued out at the length the marks deserve. Study notes — ten condensed topics organised the way the paper is: choosing views, placing them, dimensioning, sectioning, isometric, fits, modelling, and the design process. Practice & case studies — ten multiple-choice questions and five longer problems, including a full design case study, with worked answers for every one. Conventions & formula sheet — two pages carrying the projection rules, the line types, the dimensioning and sectioning conventions, the fit designations and the few formulae this paper needs. Printable resources — ten reference sheets drawn as clean vector graphics, plus blank exam stationery including isometric and grid paper for freehand practice. Practice papers — the two question papers on their own, unmarked, for a timed run.
