School & Laptop Bag CAD Patterns

I have a line of school and laptop bags that now need fully-detailed CAD patterns so they can move into sampling and production. I will provide my current hand-drawn sketches, dimension sheets, and photos of our existing prototypes; your job is to translate these references into clean, production-ready digital patterns and design files. What matters most is that the final patterns express strong aesthetic appeal and true ergonomic comfort for the end user. While toughness is always welcome, my immediate priority is how the bags look and feel when worn. You will receive clear guidance in Hindi, and I would like to review each stage in Hindi as well, so comfortable, fluent communication is essential. Preferred tools are Optitex, Gerber AccuMark, AutoCAD, or any compatible CAD package that lets us export flattened patterns with grainlines, notches, seam allowances, and a quick material consumption estimate. If you favour a different system, just confirm that the output can be delivered in DXF/AAMA or PDF for my factory. Deliverables • Separate CAD pattern files for one school bag and one laptop bag, labelled and layer-organised • A3 or US-tabloid PDF printouts with seam allowances, construction notes, and hardware call-outs • A brief spec sheet listing dimensions, panel count, and suggested materials for each bag • Two revision rounds after first draft to fine-tune fit and aesthetics When you reply, please mention the CAD software you use and share a sample of a recent soft-goods pattern so I can gauge file clarity and annotation style.
