Technical drawing

This book is intended as a class text and reference book in technical drawing. It contains a great number of problems covering every phase of the subject, and it consti-tutes a complete teaching unit in itself. In addition to the problems ỉn the text, three complete workbooks have been prepared especially for use with.Technical Draiving Probỉems, Series 1, by Giesecke, Mitchell, Spencer, and Hill; Technical Drau)- ing Problems, Series 2, by Spencer; and Technical Draioing Probỉems, Series 3, by Spencer and Hill. Thus, there are available four alternate sources of problems, and problem assignments may be varied easily from year to year. In general, it is expected that the teacher who uses this text, and one of the three workbooks, will supplement the workbook sheets by assignments from the text to be drawn upon blank paper.
