In order to provide a design support technology that enables the assembled positions of components to be selected, tolerances to be input, and a cumulative assembly precision to be estimated even if the assembly sequence is not configured in each case, a 3D CAD data analysis device (4) in a design support system for an assembly composed of multiple parts comprises: a means for generating a dynamic model, which generates a dynamic model comprising the disposition of each part of an assembly, shape characteristics, part attributes, and relationships between adjacent parts from 3D CAD data; a means for calculating the relative degrees of freedom of parts, which calculates the assembly precision between parts from the dimensional precision related to connections in the dynamic model, and the relative degrees of freedom of the parts, which represents motion space; and a means for calculating the assembly sequence and cumulative assembly precision, which detects connections with small relative degrees of freedom of parts, and aggregates the relative degrees of freedom of the parts according to the assembly sequence of the assembly.
