    You can do that by using scripts below.
    This code traverses all edges in the model and select the edge parallel to the x-axis.

    geometry = ExtAPI.DataModel.GeoData
assemblies = geometry.Assemblies
assemblies_count = assemblies.Count

#selection info 
selmgr=ExtAPI.SelectionManager
selmgr.ClearSelection()
selection_info = selmgr.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)

target_direction = [1, 0, 0] #Parallel to X-Axis
neg_target_direction =[ -1*i for i in target_direction]

# Select Edges parallel to Z-Axis
with Transaction():
    for assembly in assemblies:
        assembly_name = assembly.Name
        parts = assembly.Parts
        parts_count = parts.Count
        for part in parts:
            part_name = part.Name
            bodies = part.Bodies
            bodies_count = bodies.Count
            for body in bodies:
                faces = body.Faces
                faces_count = faces.Count
                for face in faces:
                    edges = face.Edges
                    edges_count = edges.Count
                    for edge in edges:
                        direction = list(edge.TangentAtParam(0))

                        if direction== target_direction:
                            selection_info.Ids.Add(edge.Id)
                        elif direction== neg_target_direction:
                            selection_info.Ids.Add(edge.Id)


selmgr.NewSelection(selection_info)
