Here is the amount that I have to move the glue point of the internal wall. A bit later, a tower will be added against this wall.
Here are 3 views of part 7 (parapet) from the outsid, inside, and top.
And here it is glued in place. Part 9 (inner side of gable) is in place but not glued.
And here are part 8 (other parapet) not quite glued (it's kind of fragile), part 10 (gable top), part 11 (rotunda parapet), and part 12 (small roof) all glued and ready to go.
One thing to mention is that I have been cutting parts out then scoring them. I should do it the other way around since it is easier scoring them before they are cut out.
Also using a straight edge is important when cutting next to next to artwork but not really next to tabs. A straight edge is also important for scoring.
