Demonstration—
The essential points in making Drawings I. (Group I, Problems in Mechanical Drawing.)
(Copies of the different problems of Group I—One each—should be in the hands of the pupils that they may refer to them as the demonstration is being given.)
Border and cutting lines, spacing the views, blocking-out, dimensions, letters, final lines. Projection and relation of views. Visible and invisible edges.
Work—
Each pupil solve his problem, freehand carefully on scratch paper first, putting on dimensions. Then carefully to full scale with border and cutting lines but no lettering or dimensions, only sheet number and pupil’s name.
Rapid workers exchange problems and solve as time allows.
