Yes of course ;)
But if the direct import of OBJ is perfect, I am not sure that the Subdivide can make something without some simplify or tricky manipulation
because it's real "Voxels" ! So some cubes or more some facetts! ;)
I must find some workaround first! :)
As it's facets Boolean Union will be the solution - but not sure that wotks for a such number of facetts in a reasonable time!
