Stitch the patterns of different shapes together to make a garment

• Implement 2D Pattern making using a desktop or web-based tool by means of Valentina API. • Create an option to stitch the patterns of different shapes together to make a garment. • User must visualize the 3D Garment ultimately. • So option to export the stitched patterns to LATEX / PGF And then subsequently to DXF And as well as 3Ds. • Parametric grading (different sizing of patterns) must be implemented. • User Interface should be provided for the user to design the patterns.

Can someone help me to accomplish this.
