Product Overview
??? student should realize at the outset that in casting shadows on architectural drawings he is dealing with materials of art rather than with materials of mathematics. The shades ajid shadows of architectural objects arc architectural things, not mathematical things. They are architectural entities, having form, mass and proportion just as have other architectural entities. Consequently these masses and shapes of dark must Ix: as carefully considered in the study of design as arc columns or entablatures, or other masses. It is, therefore, of great im]k)rtance to the draftsman or designer that he should lie familiar with the forms of those shadows which arc most common in architectural work, and with the methods most convenient for determining these and shadows in general.
The student is urged, then, to regard the mathematical part of the study of architectural shadows not as its object or its essence, but merely as its means, - having no greater architectural impor
