• r(xAngle, yAngle, zAngle)
  • r(center, xAngle, yAngle, zAngle)


  1. xAnglefloatAngle in degrees to rotate about x- axis.
  2. yAnglefloatAngle in degrees to rotate about y- axis.
  3. zAnglefloatAngle in degrees to rotate about each z- axis.
  4. centerselector{ scopeOrgin | scopeCenter }—The rotation center. scopeOrgin is the default. (used if no center selector is given).


The r operation rotates the scope of the current shape around the pivot-axes in xyz order. The center of rotation is either the scopeOrigin (scope.t) of the current shape or the scopeCenter of the current shape. 


r(x,y,z) is the same as rotate(rel,pivot,x,y,z)


Rotation centers

In this example, a mass model is split in vertical direction and the slices are rotated around the scope.t. Each slice’s scope is shown, note how the y-axes denote an axis of symmetry.
height = 18 dy = 2
Lot--> extrude(height)
split(y) { dy : r(0, 360*split.index/split.total, 0) X }*
Split in vertical direction with rotation around scope.t
The same example as above, but this time the rotations are around the scope center. 
height = 18 dy = 2
Lot--> extrude(height)
split(y) { dy : r(scopeCenter, 0, 360*split.index/split.total, 0) X }*
Split with rotation around scope center
