Coping Calculator for large steel pipes in Excel format

This Coping Calculator is a handy tool that I use to create flat patterns for different pipes cuts, includes miter cut, pipes intersecting with variable angles or a pipe piercing through another pipe.

The Excel spreadsheet includes all configurations with a graph/flat pattern that looks like a bell curve. Just input the diameter and wall thickness, or angle of intersection.

Also included a Visual Basic (.dvb) program for Autocad that will take points from the Excel spread sheet and plot a flat pattern curve directly to Autocad.

    Is the input data on pipe diameter ID or OD? Great work by the way!

    Thanks Johnny, OD is the input, also the equations in the spreadsheet considers the wall thickness for the output data.
