Orthographic Drawing PROBLEMS
PROBLEMS
PART-A, FREEHAND SKETCHING
For Problems .1 to 3.5 three orthographic views are to be sketched and the space for
each part may be kept roughly equal to 5 x 5-in. Draw a horizontal construction line at
some reasonable distance from the bottom (about 3/8′). Leave a smaller gap on the
side towards the F.V. and consider length upto about center of the space. Change this
length dimension into the required number of djvijo5 by putting small marks which
are below the marked line and separate from it. After finding out the length dimension
directly and converting it into the required number of divisions all other dimensions
should be guessed according to the number of divisions and the length of one division.
Mark width horizontally and height and width vertically leaving suitable gaps. In first
four problems each figure given in a part is a modification of the previous one., the
dimensions will be the same. After having some idea of the space in between the
views in first part,., adjust these in the other parts. For fifth problem, first mark equal
divisions on the figure itself and then the remaining procedure will be the same.
PART-B, ORTHOGRAPHIC DRAWING
For the following figures provided, draw three orthographic views according to 1st or 3rd
angle projection as recommended by the teacher.
Prob. 3.7
NOTE: Prob. 3.12 – Prob. 3.16 have not been included in soft form of book. Rather, they have been provided separately.
