In order to accelerate the three-dimensional modeling process of through-thickness orthogonal woven fabric structure, based on the interweaving rule, four independent parameters, including the number of weft layers, the weft diameter, the ground-warp diameter, and the binder-warp diameter, were utilized to establish the geometric relationships and three-dimensional models of the structure unit of through-thickness orthogonal woven fabric. According to the independent parameters, the calculation method of the axial spacing between layers of weft and ground-warp, the distance between weft in the same layer and the axis of the warp in the same layer, the distance between binder-warp in the weft direction, and the width, length and height of the structure unit were given under the ideal state. Using the 3ds Max software's Maxscript scripting language programming method, by inputting yarn diameters and layers of weft yarns, the SplineShape class objects were constructed from data point coordinates of yarns, and the weft layer, the ground-warp layer and the binder-warp were constructed, respectively, thereby realizing parametric three-dimensional modeling of this kind of woven fabric.
