An attempt at a greek fluted column

thingiverse

Originally, I played with a model of Doric column, desiring one with proper entasis. There might be a minor error in my calculations; thus, I eagerly seek alternative solutions. Upon further reflection, I identified the math issue but still lack an ideal resolution (doh!). However, I am now confident that I have found the answer. The provided SCAD code is semi-parameterized, with 'arc_r' representing the entasis arc radius on a 5/6 Greek column, 12 base width and a 1:5.5 base-to-height ratio. These dimensions are considered period correct for authentic Doric columns; however, the capital and abacus have not been taken into account yet. Some diagrams suggest that entasis may be smoothly extended through the bottom one-third of the column. This SCAD code serves as a great starting point for Greek architecture enthusiasts who wish to avoid complex calculations, with the Wikipedia trigonometry article proving particularly helpful.
