• Height (H): Across the duct, seen from the front, on the surface chosen under Sheet.
• Length (L): Along the duct.

What you get

The exact flat pattern of the part, worked out for the sheet thickness measured on the inside, the mean or the outside, with numbered press lines, the part in 3D, its weight and cutting length, and a DXF for laser, plasma or waterjet cutting (STEP as well).
