In the curved bay image above and below you can see the blue dotted lines showing the measuring positions. When you are measuring A to C. You will be following the curve of the front lip of the window sill. Then when measuring A to B & B to C. You will be measuring a straight line across these 2 points. Not following the cuve of the sill.

When it comes to measuring the D to B line across the middle of the bay. Then you will need something long and straight. You will rest this on each side of the bay. so the ends are at the external corners of the bay. Then measure from the middle straight up to the lip of the sill at point B.

If you don't have anything wide nough to place across the bay. Then use another tape measure and weight each end down on the sill. Then use the edge of the tape as your point D.

This curved bay window above will be ceiling fixed within the bay. Then wall fixed on the returns. As the bay ceiling is lower than the ceiling in the room.
