    In terms of dynamic mechanisms and some conic section questions, does anybody know if you are able to use the trammel method to draw them, or is it considered cheating, will you be docked marks if you use it?

    I'm not sure about the new course, but I know that you were allowed to in the old course. So, I doubt they've changed it.

    It's the messiest method though, I wouldn't recommend using it.

    You will have to stick your trammel guide onto the exam.

    Concentric circles ftw!

    ive got planes and traces, interpenetration, the dynamic mechanisms q and the assembliy question covered fairly wee. im just wondering can the exam catch me out or are all these questions definates.

    Dynamic mechanisms and assemblies are definite questions.

    The others are not, i.e. interpretations and planes, but they would be the two most likely questions on section B. However nowhere is it stated that they are compulsory. You should probably look at conic sections / Solids in Contact/ axonmetric / perspective. Or some of them anyway so you don't get a nasty shock in 2 weeks. You would have to know all that stuff for the short questions anyway which are worth 25%
