import mayaUsd_createStageWithNewLayer
import ufe
from pxr import Usd, UsdGeom, Gf
usdSeparator = '/'
psPathStr = mayaUsd_createStageWithNewLayer.createStageWithNewLayer()
psPath = ufe.PathString.path(psPathStr)
ps = ufe.Hierarchy.createItem(psPath)
stage = mayaUsd.lib.GetPrim(psPathStr).GetStage()
aPrim = stage.DefinePrim('/A', 'Xform')
aXformable = UsdGeom.Xformable(aPrim)
aXlateOp = aXformable.AddTranslateOp()
aXlation = Gf.Vec3d(1, 2, 3)
aXlateOp.Set(aXlation)
aUsdUfePathStr = psPathStr + ',/A'

aUsdItem = ufe.Hierarchy.createItem(aUsdUfePath)
bPrim = stage.DefinePrim('/A/B', 'Cube')
