Technisches Freihandzeichnen. Lehr- und Uebungsbuch by Ulrich Viebahn

By Ulrich Viebahn

Durch den zunehmenden Einsatz von CAD-Systemen erlangt das technische Freihandzeichnen eine neue Bedeutung. Der Leser dieses praxisbew?hrten Buches erf?hrt, wie er technische Formen, Zusammenh?nge und Ideen zeitsparend und ?berzeugend darstellen kann. Das schrittweise Vorgehen, die Diskussion leicht vermeidbarer Fehler und die Nutzung schon vorhandener F?higkeiten machen rasche ?bungserfolge zur Regel. L?sungen und Hinweise bei der Bew?ltigung der Hauptschwierigkeiten erleichtern die Arbeit. Ein konkurrenzloses Buch zum Erlernen guter Skizzierf?higkeiten!
