How to add beams for faces in named selections ?

Mohan Urs

If i have 2 named selections created through scripting, i need to create a beam between one face of first named selection and one face of the second named selection when the faces are below/above each other representing a bolted connection.

You can use the blow code where each face in the 2 named selection will be compared on the centroidal location and the beam will be created only when the z-coordinate is same.

NS1 = ExtAPI.DataModel.GetObjectsByName("Selection")[0]

NS2 = ExtAPI.DataModel.GetObjectsByName("Selection 2")[0]


geo = ExtAPI.DataModel.GeoData

face_ids2 = list(NS2.Location.Ids)

centroids2 = {}  

for fid in face_ids2:

    geoEnt = geo.GeoEntityById(fid)

    if geoEnt.Type == GeoCellTypeEnum.GeoFace:

        centroids2[fid] = geoEnt.Centroid


tol = 1e-6


# Loop over all faces in NS1

for fid1 in NS1.Location.Ids:

    geoEnt1 = geo.GeoEntityById(fid1)

    cent1 = geoEnt1.Centroid

    z1 = cent1[2]


    # For each face in NS2, compare z

    for fid2, cent2 in centroids2.items():

        z2 = cent2[2]

        if abs(z1 - z2) < tol:

            beam = ExtAPI.DataModel.Project.Model.Connections.AddBeam()

            sel_ref = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)

            sel_ref.Ids = [fid1]

            beam.ReferenceLocation = sel_ref

            sel_mob = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)

            sel_mob.Ids = [fid2]

            beam.MobileLocation = sel_mob

            beam.Radius = Quantity(2, "mm")

            break
