belive it or not im doing the same
ive just set up the views and the cross sections (A,B,C,D & E)
the width of the drawing is ok all measurements are in under 1% error
but the height is what bothers me...
the ground clearence is 170mm instead of 114mm probably because it is a drawing of a rally car. and the overall height of 1245 compared to 1268mm stated in the manual, when we subtract the numbers the heigh of the car bodywork from the sills to the roof is diffrent.
when i project the wheelbase to 2160mm the rims come to 330mm whitch is 13" thats oke, just need to check the tires.
overall lenght is 4044 mm compared to 4065 stated in the manual.
overall fairly acurate drawing.
