For a good straight fascia, add an extra inch or 2 to the tails of all your rafters (total length).
After they're up, you can snap a line to mark and trim the tails in a nice straight line, to make up for any ridge warp or marking, cutting and fixing errors.
If using a Circular Saw or Compound Miter saw, set saw bevel angle to 45° to obtain Creeper and Hip side angles.
With the saw bevel angle set to 45°, cutting hips and creepers at the plumb cut angle will produce correct side angles.

back from square) on both sides of the hip. This is the pointy end. (Don't cut yet)
from this line and mark a second, parallel line on both sides of the hip. (This is the line to cut along)
Set circular saw blade tilt angle to 45°
, cut 1 side along second line, with blade tilted toward pointy end, then flip and cut other side the same.
Print and cut full scale paper templates - fold over wood to mark and cut angles (easy)
