Glad you asked Jim.
Everything has to be cut. For instance all the glasing - i use a very sharp scissor to cut the edges of the glassing for front windows and the doors.
But i also had to cut out the holes for the windows and doors in the front fuselage. It not difficult and there is molded a thin groove so you ruffly can see where to cut. So i dremeld out the holes and then by hand filed it down to where i wanted it to be. See the early pictures (page 1) - there is some orange pinstripe-tape (for airbrus-use) that i used around the thin groove. All the dremel-cutting was done outside because you get covered in fine white dust.
The doors came almost finished. There was some excess material (carbonfiber) on the edges that had to be sanded/filed down.
The smart thing when using the tape is it can go around corners without wrinkles - it bends very easy. So i just filed down to the edge of the tape. It takes some time but not difficult at all. The files i use are these cheap ones and all the shapes are used for this project. The triangular one is very good to use in the corners of the window holes - to get those edges sharp and crisp.

The pinstripe-tape method was used when cutting all the glassing.
For the rivets i use two methods. Small plastic rivets and the glue/Cyringe method which takes some practice.
I have just ordered a bunch of 2 mm buttonhead (hex) to fasten all the windows.
