**课程名称：工程图学 (Rasm Hendesi)** **课程概述：** 本课程旨在为工程专业本科生提供工程图学的基础知识，涵盖描述性几何、正投影、工程制图标准与标注以及计算机辅助工程图学。通过学习，学生将能够熟练使用工程图纸的手动工具，掌握徒手绘制技巧，绘制各种视图和轴测图，提取缺失视图和剖视图，并初步了解工程图学软件的使用。 **主要学习内容：** * **工程图学原理与介绍：** 定义、使用方法、线型、图框、比例、几何构造（直线、圆弧、圆）。 * **多视图投影：** 第一和第三角度投影法、点、线、面的投影视图、体的视图、视图布局。 * **二维和三维图绘制：** * **轴测投影：** 点、线、面的轴测图、体的轴测图（等轴测图、斜二测图）、徒手绘制练习。 * **尺寸标注：** 标注规则与概念、直线尺寸、曲线尺寸。 * **相交线与相交体：** 面与体、体与体的相交，以及其投影。 * **剖视图：** 剖切原理、剖视图绘制（全剖、半剖、局部剖、特殊剖）、剖面线绘制。 * **提取视图：** 根据已知视图提取缺失的第三视图，根据俯视图和主视图提取侧视图，根据已知视图推导绘制轴测图。 * **徒手绘制：** 直线、环形、圆、圆锥曲线、体的等轴测图和斜二测图，以及视图和剖视图的徒手绘制。 * **计算机辅助工程图学入门：** * **二维草图绘制：** 基本原理（点、直线、圆、椭圆、圆弧、矩形、倒角、圆角、多边形）、绘图命令（镜像、阵列、偏移）、尺寸标注。 * **三维建模基础概念：** 旋转、拉伸、孔、螺旋、螺纹、倒圆角。 * **图纸创建与编辑：** 视图、剖视图、剖视、局部剖视、辅助视图的创建和编辑。 **课程目标：** 成功完成本课程后，学生能够： * 熟练掌握工程图纸的手动绘图工具和徒手绘制技巧。 * 准确绘制物体的各种视图（如主视图、俯视图、侧视图）和轴测图。 * 能够通过分析已知视图，推导出缺失的视图。 * 理解并绘制各种剖视图，以展示内部结构。 * 掌握工程图的尺寸标注规范。 * 对工程图学软件（如CAD软件）有初步的认识和基本操作能力，能够进行二维草图绘制和基础的三维建模。 * 可以学习和创建专业的工程图纸，包含各种视图和剖切。
On successful completion of this course, students will be able to use the engineering drawing manual tools in addition to the free hand sketching, draw all views and the isometric view, extract the missed views and sections, and have a brief idea on using the engineering drawing software.The course provides the undergraduate engineering student with a background in descriptive geometry, orthographic projection, engineering drawing standards and annotation, and computer-aided engineering graphics. Point line and plane relationships in projection; multi-view engineering drawings; auxiliary and section views; basic dimensioning and annotation.Topics:Engineering drawing principles and introductionDefinition of engineering drawingMethod of useLine typesTitle blocksDrawing scalesGeometric constructionGeometric construction on lines, arcs and circlesMulti-view projectionFirst and third angle projectionsProjection - Views of point, line and surfaceViews of solidsLay-out of viewsPictorial projectionPictorial presentation of point, line and surfacePictorial presentation of solidsIsometric and oblique sketching of solidsOblique sketching of solidIsometric sketching of solidDimensioningRules and conceptsLinear dimensioningCurved dimensioningIntersectionsCutting planesIntersecting of surfaces and solidsIntersecting of solidsSectioning and section views from Isometric drawingSections and section typesFull, half and partial sectionsSpecial sectionsHatchingExtracting the missing third view from given viewsExtracting side view from front and top viewsExtracting the isometric by knowing all viewsSimple isometric from knowing viewsAdvanced isometric from knowing viewsFree hand sketchingFree hand sketching of lines, rings, circles and conic sectionsIsometric and oblique free hand sketching of solidsFree hand sketching of views and sectionsIntroduction to computer graphicsLearning the basic principles of 2D sketchLine- SP-line - circle- ellipse- arc- rectangle -fillet- chamfer- polygon - mirror - rectangular pattern- circular pattern -offset - dimensionsBasic concept of 3D modelingRevolve - extrude - hole -coil - thread -filletLearning and creation of Drawing sheetsViews - sections - breakout view - Auxiliary view
