3d model coordinate problem

Although these *.obj extension models we have received are coordinated, when we put them into the application, the model occupies a space in the space because the projection system does not recognize it, and it is very troublesome to place it in the right place. When we want to use this data, which we have produced with location sensitivity for the engineering solution, within the institution with the help of the cessium application, the solution will not be healthy because there is no location sensitivity. Is it possible to import the model including projection from such model files?

I assume this is a duplicate of 3d bulding proses?
