After that, the length value of the flexible cable required by the target product needs to be obtained, and the corresponding size lengths of a plurality of linear materials are generated according to the length value; and marking the size lengths corresponding to the linear materials as the false marking values of the object classes corresponding to the linear materials.

Wherein L1, L2, Ln; s1, S2 and Sn are driving sizes of the characteristic creation of the driving cable, and based on the three-dimensional model creation, the distance from the endpoint coordinate of the left end of the Dn connector coordinate to the endpoint coordinate of the right end of the captured L is calculated to obtain the initial length value of the Ln; calculating the distance from the left end point coordinate of the L to the right end point coordinate of the Cn connector coordinate by capturing the left end point coordinate of the L to obtain an initial length value of Sn; and L1, L2, Ln; the dimensioning of S1, S2, Sn is derived from the actual requirement of the cable design input, i.e. the dummy dimension, which in turn drives the assignment of the conductor characteristics through the branch channel, respectively. Wherein A, B, A1 is a fixed value preset according to the size of the drawing sheet to determine the initial position of the connector, and C, D is the actual size of the connector.
Specifically, according to the method, a cable assembly schematic diagram is quickly created on a CATIA platform, and the method is called through secondary development in the CATIA: 1. designing a component composition schematic diagram according to the component composition according to the design diagram; 2. marking the length of each branch of the cable assembly according to the length actually required by installation, such as 50 meters; 3. automatically searching and calculating the geometric wire harness branches passed by each wire according to the wiring relation; 4. and (5) obtaining the labeled size value of each geometric harness branch, summing the false sizes of the passed geometric harness branches inquired in the step (3), and assigning the false sizes as the characteristic length of the wire, and 5. creating a linear material lightweight characteristic object. The three-dimensional geometrical layout of the cable assembly branch can be schematically shown through the steps, and the linear material characteristics are as follows: 1, automatically counting real material data based on lightweight linear material characteristics, and designing a three-dimensional model based on a cable assembly created by pseudo-size driven linear characteristics.
In the embodiment, when the light weight characteristic of the linear material is created by labeling the pseudo size of the wire harness geometry of the cable assembly in sections, the light weight characteristic of the corresponding wire is assigned by the numerical value accumulated by labeling the size of the wire harness in sections, so that the advantage of simplicity of a schematic layout mode of a drawing of a traditional two-dimensional cable assembly is kept, meanwhile, the modeling of a single flexible cable assembly is carried out by adopting three-dimensional software, and the structural 1:1 expression of the characteristic of the linear material is realized.
