Aqua Glass Shower Tileboard Border

I am remod'ng my upstairs bath and need some help. I am at a loss for finding any diagram (i'm very visually oriented) for the tileboard borders/moulding. Inside/outside/cap etc. I know so little. The shower is installed in an interior/exterior/partition wall. I am skirting the top 9" above the shower, and the partition extends a few inches forward of the front edges of the shower with a vinyl-like tile sheeting. I did not countersink this shower into the drywall because it is a lathe/plaster historic home and a reall pain in that regard. I raised a facia with luan and plywood out to and over the shower flange. I just want the diagram so I can complete this project and start the next one...tearing out the first-floor bath and doing it allll ovveeerr again! Thanks ahead of time.
