Shanghai Tower, as the tallest building in Shanghai, has a total height of 632m and was designed by the well-known Gensler company. The basic process of its formation is an equilateral triangle with inverted rounded corners, which is rotated 120° from the bottom to the top, and the swept shape is the final geometric shape. In fact, the top end was redesigned to avoid the shape being dull. Since I only tried to rotate the equilateral triangle with inverted rounded corners 120° during the process of rising, I did not model the top end, and then used adaptive component to complete the family placement in Revit.
Because the building is large and has a high overall height, the process of dividing the model surface and finally placing components was time-consuming, but the model was eventually completed.
