It's a long time since I've done this but it should be straightforward enough. Save your project then click File/Export Scenery Wizard. Direct the Base Location & Destination to the desired folders & click OK. (There are also 3 export options - Auto, Scenery only & Scenery + AFD.) I would normally create a destination folder to export my own scenery to.

Right, we seem to be getting somewhere. If you're exporting the BGL files to an activated folder you should see it being added to the database when you next start the sim. You didn't say which version of CFS/FS you're creating this scenery for. This is important. The FSSC AFD BGL will work in CFS2 or FS2002 but not FS9. I'll have to refresh the old grey cells but I think you can add an entry that displays in the "Search addon-scenery" option on the FS9 Airport menu. Proper menu entries can be added with Afcad.

I'm not sure FSSC is ideal for mountains. Terrain mesh & landclass would be better for that. Things have changed a lot since FS9 was released. I'm not familiar with all the new methods & utilities.

For conventional scenery created with FSSC make sure you added a Flatten area. Your new signs & similar scenery objects might be there but below the default mesh.

I've not tried it in FS but it should be possible to do what you want with FSSC. Instead of trying to create the mountains experiment with the Flat Area feature & try carving a gorge into the default terrain.
