Tube Sheet Generator

Generate tube sheet hole patterns for heat exchangers, preview the layout, and export DXF or STEP files directly from the browser.

Open utility

What it does​

  • Builds square or triangular pitch patterns inside a circular tube sheet
  • Shows a live 2D preview with optional pass partitions
  • Exports DXF for 2D layouts and STEP for 3D solids

Inputs you control​

  • Tube sheet diameter, thickness, and edge margin
  • Tube diameter, pitch, and layout pattern
  • Pass count, partition width, and orientation (visual guide)

Output notes​

  • DXF export includes the tube sheet outline and all tube holes.
  • STEP export runs on WebAssembly in the browser; large hole counts may take longer.
