00:01 Hello students in this question we are asked what is pictorial drawing that is a first question pictorial drawing so pictorial drawing is a type of illustration that represents an object in three -dimensional form so if you have a body in 2d you express those in three dimensions like you have a box here.

00:29 So you need to express them so you can draw the box in in 3d that is the pictorial representation of that right unlike orthographic drawings which shows multiple views of the object separately like from the top view the elevation or the side view all these things has to be separately drawn in orthopedic orthographic drawings so instead of that you can just draw realistic and easily understandable 3d view of the the object combining the multiple views into a single representation that is the idea so multiple views that is 3d in single drawing that is pictorial drawing now for what purposes are pictorial drawings used so mostly it is used for communication use of those communication visualization so it helps to convey appearance structures and assembly of objects in a more intuitive manner the pictorial drawings are commonly used in design engineering and architecture and other various fields of communication of ideas right, and this is where it is used third what government sponsored standard? regulates the pictorial drawings there is no specific standard which universally regulates but there are some called iso which is called international organization for standardization and asme which provide guidelines it doesn't regulate, but it provides guidelines and standards for various aspects of technical drawings so there are recommendations of pictorial representations fourth one what are the key attributes to axiometric drawing so axiometric drawing has isometric diametric and trimetric projections so this in axiometric the lines that are parallel in three -dimensional space remain parallel in the drawing so the parallel lines are clearly depicted all three axes are represented unequally so it will lead to varying angle between the axis.

03:24 So there is unevenness in dimensions, okay, that is the second feature.

03:30 This is the first feature second feature and then measurements along the axis are scaled uniformly so the scaling is uniform in measurements along the axis.

03:47 Okay, that is also some the case now coming to the fifth one what type of pictorial drawing has settings and tools configured to autocad so the commonly used for three -dimensional representation autocad drawing is isometric drawings maintain equal angles between axes, so it makes the easier to work with cad...
