Vertical Curve Bypass Tool

📏 Vertical Curve Avoidance Tool

Avoid vertical curves by using simple grade breaks.

This spreadsheet helps civil engineers and designers approximate points along a curve without using complex equations. By replacing curves with evenly spaced grade transitions, you can simplify grading design and stay within slope constraints.

✅ What It Does:

Approximates points along a curve using parabolic math and linear segments

Calculates how many segments are needed based on your inputs

Generates station and elevation points using a clean, editable table

Rounds elevations to the nearest 0.05 ft for real-world grading

Warns you when a true vertical curve is required

📊 Included:

Editable input section for elevation, distance, slope constraints

Automated point/station/elevation table

Built-in diagram and step-by-step instructions

All cells unlocked and easy to follow

💡 Use This Tool To:

Avoid vertical curve design when slope changes are small
