I want to use a 'local coordinate system' to define parts in my Python script:

origin = Point.Create(1, 1, 1)
x_Direction = Direction.DirX
y_Direction = Direction.DirY
result = DatumOriginCreator.Create(origin, x_Direction, y_Direction)
LCS = result.CreatedOrigin
LCS.SetName('Bar1')

This works, I get an origin in my Structure called 'Bar1'

 

But if I want to define a new part relative to origin 'Bar1' the part is still generated in the WCS or base origin:

result = CylinderBody.Create(Point.Create(0, 0, 0),                               Point.Create(0, 0, 10),                               Point.Create(0, 1, 10 ), ExtrudeType.None)
RenameObject.Execute(Selection.Create(result.CreatedBodies[0]), 'Drill')

How can I activate the LCS ?

It's not possible to designate a user defined coordinate system as the new origin for the solid model.

However, selecting the origin as the basis for a sketch plane will define that location as (0, 0) for the sketch.  My advice would be to alter your approach slightly and create a sketched circle, then use the Pull command to create the cylinder.

A simple example is below:

# Set Sketch Plane
selection = Selection.Create(CoordinateSystem1)
result = ViewHelper.SetSketchPlane(selection, Info1)

# Sketch Circle
origin = Point2D.Create(MM(0), MM(0))
result = SketchCircle.Create(origin, MM(10))

# Solidify Sketch
mode = InteractionMode.Solid
result = ViewHelper.SetViewMode(mode, Info2)

# Extrude 1 Face
selection = Selection.Create(Face1)
options = ExtrudeFaceOptions()
options.ExtrudeType = ExtrudeType.Add
result = ExtrudeFaces.Execute(selection, MM(25), options, Info3)

Brian Bueno thanks for your quick reply.

I think it limits the use of LCS'es when you are modelling in 3D. But ok, I'll use the sketch method then.
