Use the scaling tools to adjust the blueprint so it fits the chassis sketch. Now, take that car blueprint and apply it to the same plane as the sketch. It doesn't have to be super detailed, just include the basic measurements you got from the side view on the picture above. Next, in Inventor, create a sketch XY of your chassis from the side. (Hint: Use the picture above to see exactly what parts of the chassis need to be measured.) The total length, width, and height of the space taken up by the spars, motor, and wires sticking out of the chassis on top. The distance between the rear axle and the rear end of the chassis. The distance between the front axle and the front end of the chassis.

The distance between the front and back axles

But first, you will need to get a few measurements from your chassis. For the next step, you will need to use your car blueprint that you found earlier.
