help Find an actual object that contains at least FIVE $(5)$ features $($e$.$g$.$ rectangle, sphere, cylinder, holes, slots, or chamfers$).$

a$)$ Draw orthogonal views $($top$,$ side and front$)$ of the objects using CAD software, put the views in a title block and show several pictures of the actual object with a measuring device $($e$.$g$.$ a ruler or a calliper$),$ as suggested in Figure $1.$ The unit used in the drawing is in millimetres and the tolerance value between the actual and the model is $\backslash (\backslash$pm $1\backslash$mathrm$\{$~mm$\}\backslash ).$

Note: The tutor has the right to request a student to show the actual object to check for the validity of the model at random. A model with dimensions too far different from the actual object can be requested to be redrawn.

Remember: Do not copy the example given in this question.

b$)$ Construct the object in a$)$ into a $3$D solid using the geometric construction methods $($refer to Unit $2,$ sweeping, and$/$or primitive approach$).$ Describe the step$-$by$-$step process of the $3$D solid construction and use sketched diagrams to help with the explanation.
