Curtain Wall Panels Merged

Can someone tell be how to merge two curtain wall panels together .

Thanks

What you want to do is actually delete the grid line in the curtain wall. Hover over the grid line and tab until you can select it. In the Modify|Curtain Wall Grids tab that appears in the ribbon you'll see the last command is Add/Remove Segments. Click that tool and select the portion of the grid line you want to delete.

Thanks, job done.
