polyline3d

Creates a polyline from a list of [x, y, z] coordinates.

Parameters

• points : The list of [x, y, z] points of the polyline. The points are indexed from 0 to n-1.
• diameter : The line diameter.
• startingStyle : The end-cap style of the starting point. The value must be "CAP_BUTT", "CAP_CIRCLE" or "CAP_SPHERE". The default value is "CAP_CIRCLE".
• endingStyle : The end-cap style of the ending point. The value must be "CAP_BUTT", "CAP_CIRCLE" or "CAP_SPHERE". The default value is "CAP_CIRCLE".
• $fa, $fs, $fn : Used by the circle or sphere module internally. Check the circle module or the sphere module for more details. The final fragments of a circle will be a multiple of 4 to fit edges if possible.
