CETG 111 (Engineering graphics) Project RELEASE DATE: 16 September 2024 DUE DATE: Thursday (07 November 2024 before 1700hrs) SUBMISSION VENUE: ENGINEERING BUILDING (A depository box will be availed at to your TAs) SOLIDWORKS SYSTEM TO DEMONSTRATE MULTI VIEW PROJECTION (60%) In multi view projection, especially the quadrant-based system defined by the quartet of first, second, third, and fourth angle projection, at the simplest and highest level that gives the front view (FV) and top view (TV), the object to be drawn is assumed to be located a quadrant between the vertical and horizontal planes. The horizontal plane is then rotated clockwise so that it will lay in the same plane as the vertical plane. Oftentimes, it takes time for the concept to be appreciated by beginners because of the non-availability of sufficient teaching aids. In this project, you are asked to develop a simple system in SolidWorks that could be used to demonstrate the above concept. The developed system should: 1. show both the vertical and horizontal planes, [10 Marks] 2. show a cube of 40mm size in the first quarter 50mm in front of the vertical plane and 30mm above the horizontal access, [10 Marks] 3. show how the two views of the cube are realised on the planes, [10 Marks] 4. show the rotation of the horizontal plane as it aligns with the vertical plane, and lastly [10 Marks] 5. present the two views in the manner they are presented after the above process. [10 Marks] 6. Present a video recording of you and your team members demonstrating the workings of your designed system. [10 Marks] DRAWING ANGLES AT DIFFENT INCLINATIONS USING TRIANGLES (40%) Table 1, see cases 1, shows an arrangement in which the [450-450-900] triangle can be used with the [300-600- 900] triangle to construct lines inclined at different angles to the horizontal. You will notice in the given example that the [300-600-900] triangle is the BASE. You should also notice that the [450-450-900] triangle engage each side of the BASE triangle with its shortest edge, and from the orange-coloured edges, the engagement between the two triangles is as if the [450-450-900] triangle is being rotated/revolved about the centroid (i.e., geometric centre) of the BASE. The broken lines show another arrangement between the BASE and the [450-450-900] REVOLVING triangle. Many other arrangements are possible as illustrated in Table 1 from CASE 2 to CASE 12. The above is also true for the [450-450-900] triangle as the BASE. Table 1 CASE 1: CASE 2: CASE 3: CASE 4: 1. intermediate edge of [300-600- 1. intermediate edge of [300-600- 1. intermediate edge of [300- 1. intermediate edge of [300- 900] BASE triangle horizontal, 900] BASE triangle horizontal, 600-900] BASE triangle 600-900] BASE triangle above a T-Square, and pointing above a T-Square, and pointing horizontal, above a T- horizontal, above a T- to the left to the right Square, and pointing to the Square, and pointing to the 2.

(Strict conformity, 1 Mark or award ZERO for every drawing not separated as illustrated below and proceed to grade next drawing) [2 Marks] 2. the shortest sides of all BASE triangles are to be drawn to 40mm. (Strict conformity, 2 Marks for each correctly sized base triangle or award ZERO and proceed to grade next drawing) - SSB50 [2 Marks] 3. Moreover, all the REVOLVING triangles should adopt a rotational format around the BASE triangle as illustrated in Figure 1 and Table 1. (Strict conformity, 1 Mark for each triangle in rotational format to two of its neighbours or award ZERO and proceed to grade next drawing) - RTEEB [3 Marks] 4. the interfacing edges of the REVOLVING triangles shall be the same size as the edge of the BASE triangle with which it interfaces and correctly constructed. (Strict conformity, 1 Mark or award ZERO and proceed to grade next drawing) - RTRF. [3 Marks] 5. the BASE triangle is to be centralised on an A3 drawing paper in landscape as taught in this course. Graded only if (1) above is correct. (Strict conformity, 1 Mark or ZERO) - BTC [3 Marks] 7. visible, correct, and consistent linetypes for the outlines (Strict conformity, 1 Mark or ZERO) - LT [3 Marks] 8. there shall be no dimensions on the drawings. (Strict conformity) [deduct 2 Marks] 9. All the drawing sheets shall have a title block in which ONLY your student IDs will be given in correct lettering as taught in this course. (Strict conformity) - ID [2 Marks] 10. Use of correct paper margins and the title BLOCK. [2 Marks] 11. There shall be a single drawing on one A3 paper. Drawings submitted back-to-back, only one of the drawings shall be graded and the one on the back side of it awarded ZERO.
