People were wondering how you get this wavy effect with sketchup so I made this tutorial:
1: Make a box.
2: Create some simple balconies like this:
3: For this we’ll just use a simple pattern so one curve per side. Let’s say we want the building to bulge in the middle, then we start with a curve pointing inwards like this. Create one at the bottom and at the top:
4: You need 3 points to define curves properly in sketchup so create 2 lines up the side, then a curve in the middle as shown.
5: Now make a curve for each floor, the end-points and midpoint joining up as shown:
6: Once you’ve done that get rid of the excess lines
7: Select the existing curves, then copy, paste and rotate them as shown.
8: Attach them to the building:
9: Get rid of the square portions of the balconies:
10: Optional step, spice it up if you want. Add some depth to the balconies.
