There is only one download file today:
, but it contains a wealth of different functions dealing with 2D and 3D geometry, including intersections of lines, circles and spheres, simple interpolation functions, and functions for rotating points in 2D and 3D.
The original spreadsheet is described at: Intersections, interpolations, and rotations with updates at IP.xls updated and Another update to IP.xls.
Version 2 included: Finding Circle Centres in 3D , with later updates including:
Intersection points of two polylines
Perpendicular distance from points to a polyline
