Attatch elements? meshes

I need to work in obj quad meshes to export to 3ds max there’s a way to attatch elements by layers? otherwise Split Disjoint Mesh, all elements in one mesh even if doesn touch one another as a group one editable mesh for 3ds max If i need into 3ds max I can detach certain elements.

I tried eport obj, by layers, by groups but doesnt works.

Hello- I am not sure if I understand the question but Join will work on disjoint meshes. Otherwise, perhaps the settings in Export > OBJ can help.

Well I swear I tried with join, now actually works thank you so much.
