abstract = {CAD of woven textile structures has received much attention in the technical textiles community. 
Research and development has concentrated on the simple 2D weaves and some of the 3D weaves such as 
angle-interlock,  orthogonal,  multi-layer  and  hollow  woven  structures.  This  paper  addresses  the  void  in  the 
literature with respect to the more advanced and complex nodal structure and the CAD of 3D woven nodal 
textile structures. Innovative use of a k-ary tree data structure is used to keep track of nodal connectivity and 
parent-child  hierarchical  transformation  relationships.  In  addition,  the  k-ary  tree  allows  the  design  of  more 
complex nodal configurations beyond simple ‘T’ and ‘K’ shapes due to the inherent hierarchical nature of the 
tree data structure. The described nodal CAD software progresses beyond the frequently encountered simple 
2D interfaces of many existing textile CAD systems. 3D interfaces are used to allow the user to interactively 
create  and  edit  almost  any  nodal  configuration  limited  only  by  the  weaving  width  of  the  employed  loom. 
Novel and robust algorithms and modelling techniques are described to automate the nodal CAD process: 3D 
geometry  specification,  flattening  and  segmentation  of  nodal  geometry,  design  paper  mapping  and  weave 
architecture allocation to include: automatic computation of strut weaves, strut composite weaves and semi-
automatic  computation  of  stitching  points.  3D  nodal  CAD  has  been  implemented  in  C++  as  part  of  the 
ongoing WeaveStudio CAD/CAM software system.
