The part you need, as the sheet you cut.
Trueflat turns the dimensions of a sheet-metal part into its exact flat pattern — cones, transitions, tees, elbows and ducts — and hands it to you as a drawing, a DXF for the cutter or a 1:1 print. No signal needed.
Fifty-nine shapes
Cones and frustums, square-to-round and other transitions, tees and intersections, lobster-back elbows, offsets, ducts, pyramids, spheres and more.
Thickness, done right
Choose inside, centre or outside dimensions; the pattern is developed from the neutral line so the part closes at the seam.
DXF and 1:1 PDF
Send the outline straight to the laser or plasma, or print it at full size with a 100 mm check line to confirm the scale.
Layout by hand
No cutter? The ordinate guide gives you the points to measure, punch and join on the sheet.
Checked geometry
Every pattern is computed by two independent methods and compared before it ships.
