Conical Rainhead Flat Pattern Needed

I have a conical rainhead to fabricate in stainless steel with a base diameter larger than 20 inches. Before any cutting begins on the workshop’s CNC plasma, I need a clean, ready-to-cut flat pattern that unfolds the cone accurately, includes all seam allowances, and clearly marks bend lines, notches, and any overlap for TIG welding.

Send me:

• A fully dimensioned 2D pattern in DWG or DXF
• A PDF print for quick shop reference
• A short note on the development method you used (SolidWorks sheet-metal feature, AutoCAD, Inventor, etc.) so my team can reproduce it later if we tweak the angles.

Tolerance target is ±0.5 mm along critical edges; please keep that in mind when laying out arcs and stretch-outs. If you have produced flat patterns for large-diameter stainless cones before, this should be straightforward. I will review the file on receipt, verify the true length of the seam, and sign off once the pattern nests correctly on our stock sheet.
