Rotates the seam around the pipe; does not change the joint.

Print, assemble and cut
- Print the downloaded PDF on A4 at Actual size / 100%. Disable Fit, Shrink and printer scaling. Measure the 100 mm scale bar before use.
- Trim each sheet to its tile frame. Butt matching tile edges together using the row/column labels and registration ticks, then tape.
- Cut out the strip along the solid profile and the rectangular sides and bottom. Wrap it around the pipe; the 0 and circumference seam lines must meet. The 10 mm tab overlaps for taping.
- The template is on the retained pipe side. Mark the solid curve and remove material beyond it. Keep the saw kerf on the waste side. Bevel or dress the wall where needed.
Geometry and DXF
DXF exports the complete unwrapped template at 1:1 in millimetres, without A4 tiling. CUT contains the selected profile and retained-strip boundary; OUTER_REF and INNER_REF are reference curves; SEAM marks the wrap join; TAB is the optional paper overlap. For CNC work, use CUT only and set kerf compensation in your CAM software. Reference, seam and tab layers are not cutting paths. Confirm millimetres when importing.
Pipe-to-pipe joints have intersecting centre lines, no lateral offset, and meet the outside surface of the mating pipe. The mating diameter must be at least the cut-pipe diameter. The mating pipe wall thickness does not change this outside saddle.
The angle is between pipe centre lines, or between the cut pipe axis and the plate surface: 90° is a right-angle saddle or square plate cut. Supported range: 5–90°. This is an end cope, not a through-hole template.
The solid clearance line is the maximum intersection position across every radius from the inner to the outer wall, at each circumferential position. A cut made radially through the wall along that line clears the mating surface, although local gaps may remain. Outer-edge mode gives the exact outside intersection and may require internal beveling. Dashed inner and outer curves are references only; both are mapped to the outside wrap circumference. No weld gap, kerf allowance or weld bevel is added.
Use actual measured OD and thickness. Check a trial fit before cutting the finished component. Paper stretch, printer accuracy, ovality and coatings affect fit.
