The order is built according to the rules given by the Italian Renaissance architect Giacomo Barozzi da Vignola.
Used literature: I.B. Mikhalovsky "Architectural Forms of Antiquity" 1949; O. Garneri "Orders of Civil Architecture" 1937
For construction accuracy, the value of the Module is set to 1080 mm, so the model is quite large, with overall dimensions of 45,500 x 15,300 x 30,780 mm.

The model includes an Ionic order of two types: with decorations and without.
Without decorations - an arch without a pedestal, three-quarter columns.
With decorations - an arch with a pedestal, detached columns with pilasters.
You can vary these parameters and model different types of architectural porticoes.
In a separate order, the modifier stack is not minimized for the possibility of further building an entablature.
