Isometric Views with Circles and Curves

• Isometric Views are one of the forms of 3D
  views that you need to know about in the Standard
  Grade Graphic Communication course.
• This type of drawing shows the length,
  breadth, and height of the object being drawn.
• An isometric is drawn with a corner closest
  to the viewer.
• All vertical lines and all lines angled
  back at 30o can be measured accurately. No other
  lines on Isometric views can be measured.

Isometric Views with Circles and Curves

• If you are sitting an SQA Credit paper in
  Graphic Communication, you will be required to
  know how to draw isometric views with curves.
• This type of drawing is always included in
  the final paper each year.
• The table on the following slide shows when
  each type of drawing was used and how many marks
  were allocated to it.
• You will need to know how to draw full and
  part circles and also sloping edges and surfaces.
• The ability to be able to answer questions
  about isometrics will be a great help in letting
  you reach the pass mark in the Credit exam paper.
  
• If you are sitting the General paper you
  will need to know how to draw Isometric Views,
  although they will not normally include curves
  and circles, but will include sloping edges and
  surfaces.
