Programmazione e linguaggio GDL

Programmazione e linguaggio GDL

Programmazione GDL e geometria analitica: Il testo affronta dal punto di vista matematico ed analitico il linguaggio GDL, sfruttato all'interno di Archicad per generare componenti architettoniche ed oggetti di arredo.

It is not a textbook on language GDL, but a text of geometry that takes advantage of the GDL as a means of research and verification. The PDF ebook version is free. The printed version includes a DVD with sample library.
