roof corner cropped unintentionally -- where to look to correct?

[proto]

The roof corners are cropped somehow & i've tried various pet palette edits that don't seem to resolve the corners. Any suggestions where to look to resolve these eave corners?

I rebuilt it from scratch & have managed to eliminate those cropped corners.

When trying to edit that errant roof object, I did see the cut corners disappear when I pulled the ridge corner out creating an angled rake edge in plan.

And I even got one corner chamfer to disappear by then returning the rake edge back to perpendicular w/ the ridge, but the other persisted.

The perimeter of a roof is just like a polygon.

You can move nodes around just by dragging.

Or grab the edge and offset it outwards,and the corner will disappear.

Yeah, that’s what was odd: from the pet palette, I tried Move node; Offset edge; and both Add/Subtract polygon shapes, but the cut corners were persistent. With Offset edge, they would just move to wherever the new edge was. With Move node, I couldn’t drag one over the other to make a 90deg corner. It just refused/reverted to the cut corner.

When I pulled the node for the ridge end to create a diagonal gable edge, the corners would disappear. But then they’d return when I pushed the ridge end back to an orthogonal location (for a rectangular plan shape.)

Your roof is connected to something.

That could be causing the trim.

I did wonder why it turns gray at those corners instead of seeing the composite layered materials sliced…

There was a shed dormer with two sidewalls, so it was a roof trim connecting this roof to the lower edge of those walls; you can see the cut line of the opening beyond in the 3rd image in the OP (sidewalls not shown in that image)
