Q.15 to Q.18 : Read the following paragraph and answer the questions given below:
4X1=4

“Isometric art is a drawing or illustration style that makes two-dimensional figures
appear as three dimensional. From the Greek for “equal measure,” isometric images
can illustrate interiors, exteriors, objects, or logos with height, width, and depth to create
the illusion of a 3D perspective.”
It uses isometric drawings/projections — for everything from simple shapes to complex
animations. It is a type of axonometric projection (drawing measured along axes so
they maintain a consistent scale). As compared to perspective projection, they appear
exactly the same no matter how you place them on a canvas or where the viewer
stands. Isometric shapes appear in architectural/structural drawings, interior design
layouts, isometric maps, comics, video game art, infographics, icons, and 3D logos.
And now, isometric drawings are popping up in the metaverse as NFT buildings and
other objects as Adobe puts it to discover the creative design side on their website.

4X1=4

As we enter the building of NSIC (National Small Industries Corporation), an ISO
9001:2015 certified Government of India Enterprise under Ministry of Micro, Small and
Medium Enterprises (MSME), Delhi, a structure of its logo welcomes us. Alongside are
3D models of two fasteners highlighting the importance of these components, which
though small are inevitable for machines in use in daily life, in automobiles, electronic
products, construction structures, aerospace - almost in every industry. They are used
to join, assemble or hold single/multiple parts together either permanently or non-
permanently. Due to their growing demand and use across diverse fields, the Indian
industrial fasteners market which was valued at USD 9,064 million in 2022 is
projected to reach USD 17,868 million by 2030, according to a recent report by Straits
Research. Some of the industrial fasteners are bolts, screws, nuts, rivets, studs etc.
They may be threaded or non-threaded and are available in various standard shapes,
designs and sizes and materials, according to their utility.
