Export Mesh in Local Coordinate System
Hello
In mechanical scripting, is there a simple method to get mesh coordinates in a local coordinate system (cartesian).
Do I have to program the transformation myself or can I use some already programmed methods ?
I found something with 4x4 matrix, but I'm too old for that ...
Thanks

Oups sorry
It was quite easy to do with csys.matrix...
Just surprised there is no method to do this nativelybye

FYI you can use some DPF operators to rotate data to a given CS (matrix).
import mech_dpf
import Ans.DataProcessing as dpfdef RotationMatrixFieldFromCS(CsName):
"""- """
- CS = ExtAPI.DataModel.GetObjectsByName(CsName)[0]
- CsMatrix = list(CS.Matrix)
- TransformMatrix = [CsMatrix[i] for i in [0,3,6,1,4,7,2,5,8]]
- rot_mat_f = dpf.FieldsFactory.CreateScalarField(1)
- rot_mat_f.Data = TransformMatrix
- return rot_mat_f
def RotationOperatorFromCs(CsName, FieldsContainer):
"""
"""
rot_mat_f=RotationMatrixFieldFromCS(CsName)
RotateOp = dpf.operators.geo.rotate_fc() # operator instantiation
RotateOp.inputs.fields_container.Connect(FieldsContainer)
RotateOp.inputs.coordinate_system.Connect(rot_mat_f)
return RotateOpdef AlignFieldToCs(CsName, FieldsContainer):
"""
Take a field and align it to a local CS in Mechanical by its Name
"""
RotateOp=RotationOperatorFromCs(CsName, FieldsContainer)
RotField=RotateOp.outputs.fields_container.GetData()
return RotFielddef ObjByName(Name):
return ExtAPI.DataModel.GetObjectsByName(Name)[0]0 -
Thanks Mike for this method.
I'm not familiar with DPF, but I'll try to learn how to use it.0
