1. Answer the following in brief.
a. The axis of the solid is perpendicular to V.P., then which view should be drawn first and which view can be projected from it. [R-CO3]
a) front, top b) top, side c) side, front d) top, front
b. If a right angled triangle is made to revolve about its perpendicular side, the solid formed is CONE [U-CO3]
c. A square pyramid is placed on H.P. on its square base. A section plane perpendicular to V.P. and parallel to H.P. is cutting the solid. The true section will be____ [Ap-CO3]
a) Square b) triangle c) irregular pentagon d) rhombus
d. Isometric projection is used to create a pictorial drawing of an object. It is defined as a single-view parallel projection obtained by keeping the object in such a position that all the three mutually perpendicular geo- metrical axes are equally inclined to the plane of projection. This axes is known as isometric axes. The angle between the isometric axes is 120° [R-CO4]
e. From course research paper titled "ATTITUDE MEASUREMENT BASED ON IMAGINARY RAY TRACKING MODEL AND ORTHOGRAPHIC PROJECTION ITERATION ALGORITHM" camera models and attitude-solving algorithms are the key technologies that determine measurement accuracy, effectiveness, and applicability in the field of vision-based attitude estimation. Identify the different technologies used in the vision-based attitude estimation process.? [U-CRP]
answer 1. Imaging ray tracking camera model
2. Attitude from orthographic projection with iterations algorithm
f. The CAD system creates an environment to prepare engineering drawings interactively. Most CAD systems available commercially are menu-driven. Commands can be typed directly with the help of a keyboard or picked from the screen menu. The command which is used to create one or more copies of the selected objects at another location_____ [Ap-CO4]
a) Chamfer b) Fillet c) copy d) Extend
Problem 2(a) A hexagonal prism, base 30mm side and axis 75 mm long, has an edges of the base parallel to the H.P. and inclined at 45° to the V.P. Its axis makes an angle of 60° with the H.P. Draw its projections. (page no.309) [8M Ap - CO3]
PROBLEM NO.2(b)
A square pyramid, base 50 mm side and axis 75 mm long, is resting on the H.P. on one of its triangular faces, the top view of the axis making an angle of 30° with the V.P. It is cut by a horizontal section plane, the V.T. of which intersects the axis at a point 6 mm from the base. Draw the front view, sectional top view. [8M Ap - CO3]
3a) convert the orthographic projections shown in fig.1 into an isometric view [8M Ap - CO3]
3b. Draw the front view, top view, and side view of the given isometric view shown in fig.2 [Ap-8M-CO4]
4(a) Draw the projections of a square prism of the side of the base 40mm on the H.P and axis 65mm long., a side of the base inclined at 30° to the V.P. and the axis 50 mm in front of the V.P. (page no. 279)
4(b) Draw the isometric view of a cylinder of 40 mm diameter and axis is 70mm length. [4M Ap CO4]
4(c) A cube of 65 mm long edges has its vertical faces equally inclined to the V.P. It is cut by a section plane, perpendicular to the V.P., so that the true shape of the section is a regular hexagon. Determine the inclination of the cutting plane with the H.P. and draw the sectional top view [4M Ap CO3]
4d) Draw the Front view and Top view of the object shown pictorially [Ap- 4M]
