Page 114 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
Page 109 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.

Page 134 - ... into any number of equal parts (twelve for instance) and through the points of division H, I, L, M, and N, draw arcs having G as a center. With the dividers...
Page 82 - They should not fall short of the guide lines nor extend beyond them. As these letters are inclined they will look better if the inclination is the same for all. As an aid to the beginner, he can draw light pencil lines, about ^ inch apart, forming the proper angle with the parallel lines already drawn. The inclination is often made about 70 degrees ; but as a 60-degree triangle is at hand, it may be used.
Page 187 - ... In Fig. 70, take especial notice of the shade lines. These are put on as if the group were made in one piece ; and the shadows cast by the blocks on one another are disregarded.

In oblique projection, as in isometric, the end sought for is the same — a more or less complete representation, in one view, of any object. Oblique projection differs from isometric in that one...
Page 174 - ... element is taken from the elevation A, of either contour element. All of the elements of the cone are of the same length, so when the cone is rolled each point of the base as it touches the plane will be at the same distance from the vertex. From this it follows that the development of the base will be the arc of a circle of radius equal to the length of an element. To find the length of this arc which is equal to the distance around the base, divide the plan of the circumference of the base...
Page 95 - The letters should be pencilled free hand and the student may use the 60-degree guide lines if he desires: The guide lines of the date, name and address are similarly drawn in the lower margin. The date of completing the drawing should be placed under Fig. 3 and the name and address at the right under Fig. 4- The street address is unnecessary. It is a good plan to draw lines...
