      Hi guys, I meet a problem here. I draw the elevation, I need to make it follow the outline of building, to the effect on the right. Thanks.

        I did it using FredoBend on an approximate model. My plan was simple filleted rectangle. I faked a facade something like yours, set some fillet distances and some side distances. I made a flat facade and drew the lines representing the beginning and ending of each fillet. In other words one big rectangle with flat faces and arc faces drawn flat true circumferential distance. I bent the rectangle at each arc 90 degrees in 4 steps. Straighforward, not elegant. I also tried it with projected/extruded areas on the face. Can be done. Bend the facade successively 4 times until closed. Since your larger faces are also curved, you could work this out. Maybe I can show you my simple approach, and you can take it from there.

          Of course, there may be a way to apply it as a texture, if that is all you need with no surface features.

            Shape bender might do that i think... 😉

              @chon:
              I believe you may be right. But it would appear that the facade would need to be separated and each part bent alone, and then reassembled. I tried a new plan resembling the one in the original post. Because I used Entity Info to get arc lengths with ~ approximated distances, the accuracy of the wrap was not so good.
              A caution on the ShapeBender approach (and I don't know this for sure) would be that the edges of the segments could be distorted so that a considerable amount of hand work would be necessary to stitch this form together.
              I am pretty sure there is someone thinking this problem out. I do not have the luxury of large segments of time to apply.

                I tried the FredoBend and it worked. As you mentioned I did separated some parts then assembled. Thank you!
                But when I modify the corner, I can't really do anything to change it.

                  Is it behaving as a group, or component? Or is there some other difficulty?

                  Edit: Your figure is a group within a group within a group. You may wish it to stay that way, but you will need to do a right click>EditGroup repeatedly to get to base geometry and it appears it is editable then.

                    After the FredoBend, the corner is devided into too many geometries. I wanner modify some parts on the corner, to make more or less openings.It's difficult to do with SU default tools.

                      I suggest you try without the auto-slicer (key F4), as your shape seems already divided into small pieces.
                      Then Bend will not add more geometry.

                        It's not working with F4, because it won't bend.
