patternLinear3d	Function in std::solid	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; 1+],
  instances: number(_),
  distance: number(Length),
  axis: Axis3d | Point3d,
  useOriginal?: bool,
): [Solid; 1+]

Arguments

Name	Type	Description	Required
solids	[Solid; 1+]	The solid(s) to duplicate.	Yes
instances	number(_)	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(Length)	Distance between each repetition. Also known as 'spacing'.	Yes
axis	Axis3d or Point3d	The axis of the pattern. A 3D 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.	No

Returns

[Solid; 1+]

Examples

// / Pattern using a named axis.

  |> close()
