 Hello everyone, I am Rahul Patil, Assistant Professor, Department of Mechanical Engineering, Walchand Institute of Technology, Solapur. Today we will discuss regarding isometric views. At the end of this session, student will be able to draw the isometric views. Now with prerequisites, you know the details regarding isometric views, we will start with some simple basic problem. Problem is like this, where front view and left hand side view for the problem is given with center hole. Now you have to draw the isometric view for this. Now we will start, first draw the primary axis from this axis, mark 30 degree, join this. Now in figure front view and left hand side view given, left hand side view you have to draw on left side and front view you have to draw on right plane. Now dimension is 50 mm by 50 mm. So first draw the box with dimension 50 mm. Take 50 mm in compass from this origin, mark 50 mm. Draw iso line parallel to this axis, again mark 50 mm on this, join this mark. Now second left hand side view with dimensions 50 mm is given, take 50 mm, 15 mm. Join with the help of compass, take 15 mm dimension from origin, mark 15 mm. Draw iso line which is parallel to this axis, again from this point draw line which is parallel. Now complete, now you have completed the box required for your drawing. Again this area is not required, now inner hole with 530 is given. So you have to draw with the center point, take 25 mm from this point, from this corner. Now join this, try to use the faint lines, again second axis which is parallel to this. Now again you have to draw the circle which have diameter of 30 mm. Take in compass 15 mm dimension from center line, mark 15 mm. Now draw again iso line parallel to this, passing from this 50 mm mark, when you complete this, you will get the box in round bus shape which are dimension of 30 by 30. Now use 4 center method where this is first center, this is second center for obtaining remaining two center, from center number first, join the center again, from center number first, join the center point, from center two, again join the center point, here again join the center point. You will get center number three and center number four, draw this diagonal where intersection point, this is center number three and this is center number four. Now take from center this much radius in compass and similar way from this draw it. Now consider third center from this much radius, you have to draw remaining entity, center is little bit in less radius, this is the curve. Now similar entity you have to draw on back plane, for that purpose just consider this center you have to draw or carry out 15 mm backside, draw line parallel to this axis and shift this center backward by 15 mm from this, this dimension is 15 mm, again take same radius consider this as a radius or center point and draw, so that you will consider the depth for this content, here it will end your problem. Now with the help of four center mentor you can draw the isometric view for the given object, thank you.
