InsulationAutomaticDrafter

Description

Allows the user to select a rectangle in Rhino and creates a polyline that follows a zigzag pattern. The zigzag pattern is inscribed in the rectangle and its wave size is equal to the zigzag’s pattern side size:

1. Inscribes a zigzag pattern in a rectangle
2. Wave size of the zigzag pattern is equal to the zigzag’s pattern side size
3. The script works with both horizontal and vertical rectangles

Warning

The script won’t work on rotated rectangles that are not strictly horizontal or vertical
