Square or Rectangle to Round Transition Template
Four panels to print, measure and assemble.
Enter base width and depth, nominal round diameter and perpendicular height. Develop a centered 48-division faceted model into four labeled paper panels with explicit right-edge lap strips. The free PDF is tiled for Letter or A4 with registration marks and two-axis scale checks.
How It Works
-
Measure one datum
Enter width, depth, diameter and height in decimal millimeters or decimal/fractional inches. Height is perpendicular between the planes, not a slant length. The round diameter must fit within both base edges.
-
Choose the paper lap
Enter an explicit width, including zero. Each panel receives one right-edge paper strip. Review the nominal circle, chord inset, actual panel bounds and untrimmed paper area. No locked seam or hem allowance is inferred.
-
Print all four pieces
Export the free branded PDF. It includes Letter or A4 pattern tiles with the same input record ID, 10 mm overlap and both-axis 50 mm rulers. Use Actual Size/100%; do not Fit/Shrink or Poster-tile again.
-
Check and assemble paper
Measure the rulers in both directions. Align three crosses across each joined tile boundary, cut solid lines and fold dashed lines. Join F to R to B to L to F. Trim tab portions projecting beyond the next panel while keeping the bare geometry.
