Apply node manipulations to the geometry?

So, I’m a Blender noob. I started learning the modeling part as I’m an architect and my inicial interest was to do that. However I’m going deep into nodes and doing some tutorials.

As I’m using more than one program in my workflow at some point I would have to export the model from Blender. So, many things we do in node manipulation only appears when rendered in cycles.

How can I apply all that in the inicial object geometry so that I can export? Is there a way? Am I missing something? Am I dumb? lol

Thanks for your help!
