How to select all faces of an assembly except those with z=0.

jmaravin commented 4 months ago

Description of the feature

Hi, I am trying to select all the faces of an assembly (which is formed by several bodies) except those in the axial symmetry plane. I can select all the faces of these objects but I cannot deselect the faces which are on z=0. I can do it manully but they are about 100 faces to deselect so it takes too much time to deselect all of them. The code I use to select all the faces is the following:

faces = m3d.modeler.select_allfaces_fromobjects(objects)

Steps for implementing the feature

In any Maxwell 3D project with several bodies, run the following command:

_faces = m3d.modeler.select_allfacesfromobjects(objects)

if all bodies have a face on the symmetry plane, you could select that face by obj.bottom_face_z.id put all those faces in a list sym_face_ids and exclude the list of symmetry faces other_faces = [face.id for face in faces if face.id not in sym_face_ids]

@jmaravin Does it answer your question? Please close the issue if it does.

Hi @Samuelopez-ansys and @fwlfHS it does but not completely. I understand the method to implement but the code provided does not work.. I am unable to use the code "obj.bottom_face_z.id"
Could you please help? Jaime

@jmaravin Without a project to reproduce the workflow is quite difficult. Please share it and show what exactly you need.

Hi @Samuelopez-ansys, you are right. Please see the code below. What I am trying to do is to remove the faces at z=0 of all the cylinders through the code that @fwlfHS gave me but I am unable to do so. Could you please help?

Kind regards, Jaime

sym_face_ids = []
for Cylinder in Cylinders:
     obj = m3d.modeler.get_object_from_name(Cylinder)
     sym_face_ids.append(obj.bottom_face_z.id)
other_faces = [face for face in faces if face not in sym_face_ids]

Hi @fwlfHS, it works now. Thanks very much for your help. Appreciate it. Regards, Jaime
