A question about changing roof pitch angle in Skylark250 blocks

[chrispez]

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.

Hi @chrispez,
when developing a new block we tend to use repeatable moduli of 300 mm (we call them bits, attached screenshot for reference). That’s to make sure for example there are bow ties every 600 mm or tabs every 75 mm. In terms of workflow:

1. We tend to use Rhino for detailed models because it is very precise for measurements, and we start from developing the bits
2. First the bits are assembled into parts, then parts are assembled into cassettes
3. We constantly check for clashes within the block and among blocks. Very much a trial and error exercise. Sometimes if the space is too narrow, we have to make some decisions e.g. prioritising one connection or another (for example choosing between a tab or a bow tie). That is normally based on structural considerations depending case by case
4. Finally, we convert the 3d model into cutting files so that we can automatically apply tolerances.
   Hope that helps!

Thanks so much for this detailed response Gabriele! It’s a big help.

Will post a 25 degree pitch gable here when I’m done designing, in order for people to review and critique.

Have a good one.
