Track Modelling ( Exercise 1 - Lab 2 )

create  polygonal plane and insert the track outline photo onto it

choose mesh>create polygon tool and click on the corner on the lower left side where it begins to step inwards to form the slot, continue doing this for the track profile

after drawing the polygon

after the polygon is complete, hold the right-click option and choose vertex from the menu and adjust the placement of  any vertices as needed to match the profile closely 

polygon

select the polygon and in the hotbox, choose edit mesh>extrude then set the divisions to 20, extrude  the polygon  a small amount on the Z axis

hold the right-click option and choose edge mode then in the hotbox, choose edit mesh>insert edge loop tool and  change according to the instructions, scale the lines approximately 2.9 apart on the X axis

hold the right-click option and choose face mode, then choose the faces on the top of the slot next to the end of the track, use the shift key to select multiple faces

click on the new faces created at the end and extrude, choose edge mode and then select the two small edges  at the outer corner of the new polygon and bevel it

create deformers>nonlinear>bend, set curvature to 1, in bend1Handle channel box set rotate X to -90

With this exercise, i learnt how to use the bend and edge loop tool. This exercise could be done easily by following the instructions given.
