Yes, there are numerous radii but since you did not specify which one or ones you are having trouble "getting" it is going to be difficult to assist you until such time as you provide more detail.

You're still going to have a bit of fun.  If the "assignment" is to recreate this drawing the challenge is to find the actual radius points.  And that's the real point of the exercise.

Draw all those things you know for sure.  You should be able to get pretty far into it and fairly close.  The specification does give you some wiggle room with the statement, "Use your own discretion for any dimensions not specified".  So you can make an assumption now and again.  The key is that curves are most usually *tangent* to the straight lines they intersect.  You can use this all over the drawing to find radius points.

Dave.

Or as my first boss once told me, "Do something!  Even if it's wrong."  :)  He also told me I'd get in more trouble if he found me doing nothing.

So the more mistakes you make the faster you'll learn.  So go make some!

Dave.

Many of the arcs could be constructed using the CIRCLE command and the Tan-Tan-Radius option.

Re: my previously posted image.  I had to guess about the front end of the car because some information was blurry and thus unreadable and some was missing.  Sorry about that.
