Technical Graphics
Learning Intentions
Interpret Technical Drawings
Understand and extract information from orthographic and pictorial drawings to solve design and communication problems.
Apply Drawing Standards and Conventions
Use British Standards (BS 8888) and international conventions (ISO 128) to produce accurate, professional technical drawings that communicate clearly.
Develop Spatial Awareness and Visualisation Skills
Recognise and construct different views and projections, improving your ability to visualise 3D forms and translate them into precise 2D representations.

Practice Worksheets
Orthographic Sketching
These worksheets have been designed to help with orthographic sketching. Construction lines have been provided, including bounce lines. The trick is ensuring hidden-detail has been shown correctly.
Sectional Views
Practice creating sectional views using these practice worksheets. Construction lines have been included. Try to remember the rules about cross-hatching certain components and features.
Hexagonal Prisms
Hexagonal prisms present challenging geometry to get present. In these work sheets you must complete the orthographic views and create a Surface Development (net) of the prism.
Pyramids
Pyramids present their own unique challenges, especially when it comes to the the Surface Development. You will need to calculate the True Length of an edge. In these worksheets you get the chance to practice your skills.
Cylinders
Cylinders can be a challenge to draw on the drawing board as there are no corners - or vertices - to plot. These need to generated by dividing up the cylinder artificially. This is typically done by using a 30/60 set-square to divide the cylinder into 12.
Cones
Cones can present a greater challenge than cylinders. The same processes and techniques are used, but you need to remember all the generation lines come from the apex - the top - of the cone.
Isometric Sketching
Reading an orthographic drawing and converting back into a pictorial view shows some mastery of both view types. In these worksheets you convert orthographic views into isometric.
