A computer-implemented method designs a tying bar enclosing a plurality of concrete-reinforcing bars in a 3D scene of a computer-aided design system. The method a) provides the three-dimensional models of the concrete-reinforcing bars to be enclosed by the tying bar; and b) computes a set of traces of each of the concrete-reinforcing bars. Each trace has a trace center. Next a set of connection lines is computed. Each connection line binds the trace centers. A set of circular arcs is computed. Each circular arc surrounds at least partially a respective trace, and a set of segments. Each segment is approximately parallel to a respective connection line and connects consecutive circular arcs. The segments and circular arcs form a center curve of the tying bar in the sketch plane. Lastly, the tying bar is designed based on the center curve and the bar radius of the tying bar.
