Brown Paper Drawing of AS1684

Yesterday we spent the whole day completing our brown paper drawings of several different intersections of stud walls. We split the drawing in to thirds lengthwise and the first two thirds were split into thirds heightwise. The last third was split into a two thirds section and a one third section, so all up we had 8 different drawings.
The first column had three plan views of a corner junction, a T-junction and a a drawing that combined them both. The drawing that combined both had 10mm gyprock lining on the inside of the house and 6mm hardiflex sheeting on the outside. These drawings were pretty easy and looked quite boring.
The next three drawings in the second column had three different lintal arrangements, one with the lintal flush with the top plate, one with the lintal flush ontop of the sill trimmer, and a window without a lintal at all. Lintals are only nescessary when there is a load over the top of the window, and generally lintals are only needed if the window or door stretch is over 900mm.
The last two pictures in the third column were drawn in isometric style on an angle of 30 degrees. The top one was a picture describing how to fix two pieces of timber together to form a structural beam, where two screws must be placed at each end of the beam and each screw there after was a single screw staggered with the previous screw, at no more distance than two times the depth of the timber being used.
The last picture was three studs ontop of a single bottom plate, with each stud having different types of notches in it including 1350 max spacing for the noggings, a diagram of the crippling technique with cleats either side and notches for a diagonal timber bracing. These isometric drawings were a challenging brain teaser as i used vertical and horizontal lines to get the angle perfect at each point of the drawing. I thoroughly enjoyed having the chance to just get stuck into the drawing and completing it as it is a testament to the effort and thought i put into it.
