This paper aims to realize fast design of non-overlapping square continuous pattern, with the properties of uniform and compact layout and to avoid the stiffness and mechanical feeling caused by simple reproduction. By utilizing the feature that any quadrilateral can be seamlessly tiles, the pattern elements to be filled were arranged in a quadrilateral, or the elements were first arranged and then the contour quadrilateral was then created. The paper expanded the elements to curve-edge quadrilaterals, and presented the tessellability conditions, together with the technical plan. The rapid construction method of tessellate curve-edge quadrilateral was realized through human-computer cooperation，and the construction method of tessellate heterogeneous elements. Design tools are developed based on software commonly used by graphic designers. The case test shows that the technology can accurately identify the quadrilateral frame drawn by users, and realize the flexible space filling quadrilateral continuous pattern. The application of non-convex quadrilateral and curved quadrilateral frame increases the diversity of generated patterns. The tools' operation is based on the intelligent identification designer's hand-drawn curve processing, thus the interface can be simplified, and the interaction performance is proved reliable.
