Pictorial 3D representation on isometric axes — isometric vs non-isometric lines and angles, isometric circles, polygons and cylinders, sectioned isometric, and building a pictorial from given orthographic views.
Click an edge of the wedge below to find out whether it's isometric (parallel to one of the three axes, so it can be measured directly) or non-isometric (must be plotted from its endpoints).
Each exercise below prints as a full-scale A3 sheet — the same format used in EGD practical assessments. The reference thumbnail shows the completed drawing; redraw it full-size on paper using correct line types and true measurements along the isometric axes. Use your printer's "Actual Size" setting (not "Fit to Page").
