Solid Element Operations will help you achieve what you're after better than trim walls to roofs in this instance.

"Solid Element Operations" is in the design menu

Essentially; the roofs are operators, the walls are targets and the operation you want to perform is "subtraction with upwards extrusion"

I have to be brief right now but have a try and see if it helps.

I agree. I never use 'trim to roof' for this situation. SOE is much better especially if you change your roof panel ie lift if up or change pitch the wall automatically adjusts to suit.

You would need to split the wall at the valleys (into three lengths) for the trim to roof to work.
SEO's are better and remain interactive just in case you redesign anything.

It looks like the wall is trimming to the long roof plane that runs parallel with the wall.
Therefore it isn't trimming to the underside of the gable roofs.

Splitting it into 3 walls at the valleys means the side wall will trim to the long roof and the centre will trim to the gable roofs.

Or leave it as one wall and just SEO.

A single wall, with one "Trim to roof" operation.

I've never needed to split, either, Barry. If TTR doesn't work, it's invariably that the roof elements were not properly joined (cmd/ctrl-clicking ridges, valleys, etc to make all roof surfaces - top and bottom - fit/miter properly).

As others, I prefer SEOps for this because of the flexibility (no need to undo trim, redo trim if anything moves).

Cheers,
Karl
