Embodiments of the present invention are directed to facilitating folding of virtual objects via a three-dimensional folding tool. In embodiments, a foldable virtual object having a set of one or more fold lines is presented. A user may select a particular fold line. Based on the user selection, a three-dimensional folding tool is presented in association with the selected fold line. The three-dimensional folding tool can include a first handle on a first panel adjacent to the selected fold line and a second handle on a second panel adjacent to the selected fold line. In accordance with detecting movement of the first handle in a direction, the first panel is folded or rotated about the fold line in the direction of the movement of the first handle, while the position of the second panel is maintained.
