Jim Crume has released a new e-book in the series, Surveying Mathematics Made Simple.

In “The Myth About Spiral Curve Offsets,” Crume examines the method and formulas to calculate a true parallel offset to a centerline spiral curve.

The e-book debunks the myth that there is no such thing as a spiral curve offset.

“The Myth About Spiral Curve Offsets” is available on Amazon for $4.99.
