Last year Alfredo Medina describe a method for creating Easy Parametric Polygon using formulas for circumscribe & Inscribe polygons. He did not disclose the method to make Inscribed polygon, instead he he said that it can be done by placing the line ends to the circle. I tried this using other method withot placing the line ends to the circle. I thinked that inscribed polygon is also a circumscribed polygon for a smaller imeginery circle. If I can find out the radius of that circle, sides of circumscribed polygon to that circle can be determined, which will be the inscribed polygon required. The family is attached. Chek it & comment, weather I m currect or wrong.
Now about my problem-- what is the use of this polygon for modelling purpose, because one can not change the number of sides to change the shape of the model.
Here I attaced a pyramid type model to use as a dome of a Hindu Temple . The model has been created by sweep, using Param polygon (Octagon) as path.
Can any one guide me how can I create such model by using variable number of sides ? Like when I need I can change the base shape using side number parameters.
