patternLinear3d	Repeat a 3-dimensional solid along a linear path, with a dynamic amount of distance between each repetition, some specified number of times.	manual

Repeat a 3-dimensional solid along a linear path, with a dynamic amount of distance between each repetition, some specified number of times.

patternLinear3d(
  solids: [Solid],
  instances: integer,
  distance: number,
  axis: [number],
  useOriginal?: bool,
): [Solid]

Arguments

Name	Type	Description	Required
solids	[Solid]	The solid(s) to duplicate	Yes
instances	integer	The number of total instances. Must be greater than or equal to 1. This includes the original entity. For example, if instances is 2, there will be two copies -- the original, and one new copy. If instances is 1, this has no effect.	Yes
distance	number	Distance between each repetition. Also known as 'spacing'.	Yes
axis	[number]	The axis of the pattern. A 2D vector.	Yes
useOriginal	bool	If the target was sketched on an extrusion, setting this will use the original sketch as the target, not the entire joined solid. Defaults to false.	No

Returns

[Solid]
