Propellers

I hope you find some fresh logic spinning in the propellers. Enjoy!
Rules:
Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.
Propellers:
- Each gray dot is the midpoint of a single, 3-cell long line segment that must be drawn into the grid. Line segments are fully straight, and may be oriented horizontally, vertically, or diagonally.
- The three digits along a line segment cannot repeat, and they sum to the value given in the corresponding midpoint cell.
- Line segments do not cross, overlap, or share cells with each other.
Example: Below are some valid Propellers.

Solution code: Column 9
