This weeks revision topic is more of a concept than an entire topic. Finding the traces of a plane is part of the Oblique Plane topic but it can be asked in many different ways. The most common topics for traces to be asked as part of are Solids in Contact, Laminar Planes, Axonometric Projection. Because Traces of Planes are a concept it is vital that you understand what they are and can visualise them in both Orthographic Views and also Pictorial Views.
SYLLABUS LEARNING OUTCOMES
As this concept is overarching of so many topics it is difficult to give you one example from the syllabus but it is scattered throughout the learning outcomes.
What You Need to Know
- Distinguish between simply inclined and obliquely inclined plane surfaces. (The Oblique Plane)
- Determine the angle of inclination between given planes and the principals planes of reference. (The Oblique Plane)
- Solve problems that involve the intersection of solids by simply inclined planes and obliquely inclined planes using simply inclined section planes. (Solids Cut by Oblique Planes)
- Draw the traces of a tangent planes to solids. (Solids in Contact)
- Construct obliquely inclined planes given the angles of inclination to the principal planes of reference and to include a given line or point. (The Oblique Plane)
- Establish various spatial relationships between skew lines and other lines and planes including distance, inclination and direction.
