Click the Crane icon from the toolbar.
On the facade you want to make a crane, click on the two columns to be defined.
After clicking, the program will wait for you to click on the 3rd column.
At this stage, you can create a crane on a second line parallel to the line you clicked first. When you click on the 3rd column, there will be parallel cranes. Or you can click the 3rd column on the same line in the 3rd column stage. In this case, a single crane will be formed along the selected line.
