Pattern: branch on cylinder - transition - rectangle [fillet] to round

Transition-type branch



Cylinder and branch position



Configuration: Change

  • Ends 1 & 2 dimensions: External
  • Branches: Ends 3 & 4 dimensions: External
  • Main trimmer surface: External
  • Branch trimmed surface: Internal
  • Branch linear division (ASL): 25
  • Development precision [divisions]: 48
  • DXF text height: 3
  • Input and drawing file units: Millimeters

Some tips related to this pattern:

  • When working with branches, ensure that the trimmed/trimmer settings are correct; otherwise, the intersection may not be complete or present interferences.
  • The wrap-around template option should not be used to create a template for cutting sheet metal and bending/rolling afterwards; they are intended to be made of paper, for wrapping around an existing round pipe, to mark the cutting line.
  • wrap arround template option is only applicable to the cylinder part.
  • Note that the 3D model/rendering [within DXF download] of the main pipe or cone does NOT show the branch hole; nevertheless, the main 2D development does include the hole.
  • To obtain an oblong shape with a rounded rectangle end, your input shall be R = X/2 OR R = Y/2.
  • To obtain a circular shape with a rounded rectangle end, your inputs shall be R = X/2 AND R = Y/2.
  • By utilizing a minimal internal bending radius r (internal), or r + T/2 (CL) or r + T (external) (with r ~ 1.29 * T), a near sharp-cornered rectangle can be achieved.
