Cutting a mesh in flac3D

Hello everyone,
Is it possible to cut a flac3D mesh using surfaces ? I’d like to modify a volume but the range option won’t be sufficient since I want the top faces to be at the same pos_z.

Thank you

I do not know if i understood but:
If the faces in the model are the same of the surfaces you are using, there won’t be problems. Otherwise, you’ll get a “Saw shape” volume.

Regards

Sorry for not being precise.
I have an existing mesh and I want to create a new volume inside this mesh.
Is it possible to cut the mesh and have regular zones ? I’m trying to avoid recreating the geometry, and range option won’t be sufficient.

If there is no option to rebuild the geometry, you must adjust your limit to the existing ones:

okay, thank you Matias !
