scale	Scale a solid.	manual

Scale a solid.

By default the transform is applied in local sketch axis, therefore the origin will not move.

If you want to apply the transform in global space, set global to true. The origin of the model will move. If the model is not centered on origin and you scale globally it will look like the model moves and gets bigger at the same time. Say you have a square (1,1) - (1,2) - (2,2) - (2,1) and you scale by 2 globally it will become (2,2) - (2,4)...etc so the origin has moved from (1.5, 1.5) to (2,2).

scale(
  solids: SolidOrImportedGeometry,
  scale: [number],
  global?: bool,
): SolidOrImportedGeometry

Arguments

Name	Type	Description	Required
solids	SolidOrImportedGeometry	The solid or set of solids to scale.	Yes
scale	[number]	The scale factor for the x, y, and z axes.	Yes
global	bool	If true, the transform is applied in global space. The origin of the model will move. By default, the transform is applied in local sketch axis, therefore the origin will not move.	No

Returns

SolidOrImportedGeometry - Data for a solid or an imported geometry.
