    Did your teacher offer any explanation as to the questions raised here?

    It would/will be interesting to know just what the instructor thought important in the OP's case, now that he has turned it in.

    Don't know about all students, but the OP clearly stated he is printing it out.

    Congrats! I, too, would like to know your teacher's views regarding the issues raised here.

    All the dimensions were correct except for the circle radius in the right which was like 31.4 mm(not 32)

    Point taken and illustrated (see below), though with full circles, not arcs. Sounds like a reference back to the drafting board era. I remember those days, and enjoy reading one of the threads devoted to it. You-know-your-an-old-draughtsman-when...

    That depends on the case and objective. Here, it could be used to demonstrate that the design is actually off what it should be, given the constraints as shown, etc. An instructor may use such to quickly check just how closely the student positioned the arc.

    Thanks for getting back to us. Doesn't sound like your instructor was too worried about it. Now I'm curious how much that error counted off.

    I doubt the instructor checks the drawings very closely. The exercise is more about getting the student used to using a myriad of commands. If you want pinpoint accuracy you'll have to look elsewhere.

    That sounds much more reasonable.

    I'm proclaiming you the winner of the "Let's beat this horse to death" prize for this thread. You can pick up your hybrid metric/imperial ruler at CADTutor headquarters. We're open 24 hours; not necessarily in a row.
