Paginas web de dibujo técnico, perspectivas y mucho más

Desde este link podéis enlazar con las diferentes páginas web desarrolladas por José Antonio Cuadrado, una auténtica maravilla, con la que practicar y aprender mucho más sobre perspectiva cónica, vistas, tangencias etc. Aprovecho para expresar aquí públicamente agradecimiento a este artista y profesor.
