A question about changing roof pitch angle in Skylark250 blocks

Hi team, just wondering what the process is and design rules are for changing roof pitch / angle on the Skylark250 wall and roof blocks?

How exactly would the tie connection locations change if changing pitch to 25 degrees instead of 10 or 42 degrees. What patterns to follow, spacing requirements between tie connections, distance from edges etc? Feel free to sketch over the top of blocks your suggestions. Thanks in advance! Chris.
