I am using this program to create buildings for a Role Playing Game. One such building includes a grand staircase. The grand staircase is in the shape of a "Y" where a staircase on the right and one on the left meet in the middle to combine in a single staircase running to the floor. In my case I would like the staircase to curve to the left and right and meet at the bottom of the floor. The existing grand staircases, that I can find, are square and rigid.[url=C:\Users\Doug\Pictures\Example Grand Staircase.jpg]C:\Users\Doug\Pictures\Example Grand Staircase.jpg[/url]
