Course Code: 100104P
Course Title: Engineering Graphics and Design Lab
L–T–P–C: 0–0–4–2
Course Description:
This practical course complements the theoretical understanding of Engineering Graphics. The lab focuses on building fundamental skills in technical drawing, geometric construction, and computer-aided design (CAD). The emphasis is on visualizing objects, interpreting projections, and creating precise engineering drawings manually and digitally.
Course Objective:
- To impart foundational skills in engineering drawing, including manual and computer-aided drafting.
- To develop visualization, drawing accuracy, and interpretation of technical graphics.
- To enable students to apply CAD tools to create and edit basic engineering drawings.
Lab Guidelines:
- Perform any 10 experiments from the list provided.
- Students must maintain a practical file with drawings and CAD printouts.
- Both manual and CAD-based drafting practices are included.
List of Experiments / Activities (Any 10):
- Basics of Drawing:
- Types of lines, dimensioning methods
- Polygon construction
- Line and angle division
- Use of drawing instruments and stencil lettering
- Construction of Scales:
- Plain Scale
- Diagonal Scale
- Vernier Scale
- Conic Sections:
- Construction of Ellipse, Parabola, and Hyperbola (using the general method)
- Special Curves:
- Construction of Cycloid, Epicycloid, Hypocycloid, and Involute of a circle
- Projection of Points and Lines:
- Inclined to both Horizontal Plane (HP) and Vertical Plane (VP)
- Projection of Planes:
- Rectangular, triangular, and circular planes in inclined positions
- Projection of Solids:
- Prisms, pyramids, cones, and cylinders – in various orientations
- Sections of Solids:
- Sectioning of prisms, pyramids, cylinders, and cones
- Development of Surfaces:
- Unfolding surfaces of prisms, pyramids, cones, and cylinders
- Isometric Drawing:
- Isometric views of lines, planes, and simple solids
- Conversion between orthographic and isometric views
- Introduction to CAD Software:
- Overview of interface, tools, coordinate system, commands
- CAD Practice:
- Draw basic geometric shapes
- Apply dimensioning
- Modify objects using editing commands
Tools Required:
- Drawing instruments kit
- Engineering Drawing sheets
- CAD Software (AutoCAD or equivalent)
Learning Outcome:
By the end of the course, students will be able to:
- Accurately create 2D engineering drawings manually and digitally
- Visualize and represent 3D objects using projections
- Use CAD software tools effectively for engineering applications
