I am glad it worked!
You are placing the mesh as a DirectShape, so you can see it in any view, but the text will only be visible in the view where you created it, unless you open another view and create a new text. It is not possible to create text in 3D views with the Add Text component (View ‘{3D}’ does not support text notes creation). You can create it directly in Revit in a 3D view, although it has some problems in terms of insertion point and seeing the text when you navigate in the view. Another alternative is the Model Text, that you can actually visualize in all views (just make the depth as low as possible to make it look like a flat text), but there are no components for this in Rhino.Inside (see this link). Maybe @Japhy can shed some light on this 
.
The horizontal and vertical align are just for the text, like any regular text in Revit. It is the text justification in Revit.
