Loop Straighten
Straighten selected open edge loop by positioning vertices on a line between endpoints.

Requirements
- Edge loop must be open (have two endpoints)
- Selection must form a continuous edge loop
- Cannot be used on closed loops
Properties
Percentage
- Description: Blend from original positions (0%) to fully straight (100%)
- Range: 0.0% to 100.0%
- Default: 100.0%
- Type: Slider
How It Works
Loop Straighten positions vertices along a straight line between the loop endpoints:
- Identifies the first and last vertices of the open loop
- Calculates the straight line between these endpoints
- Projects each intermediate vertex onto this line
- Blends between original and straightened positions based on percentage
