Scad to Stl

OpenSCAD упорно не хочет конвертировать файл из формата scad в stl, пишет следующее WARNING: Nothing to export! Try building first (press F6). Жму ф6 и ни чего не происходит. Подскажите как быть? Ниже лог скада. И если есть люди кто разбирается, подскажите как наклонить соты на 13-15 градусов в одну из широких сторон

/* model honeycomb

Gian Pablo Villamil

October 2014

Customizable honeycomb generator. You can choose open or closed ended cells.

The overlap parameter controls the wall thickness of internal vs. external borders. If overlap is true, all walls will be same thickness. If overlap is false, then the

internal borders will be thicker and external thinner, so if you put two sections

together, they will mesh correctly.
