Respect grain direction
Wall and divider grain runs along part length. The base has no directional requirement in these templates. Turning a part is allowed only when its template and your material settings permit it.
Try it on a complete plan
Allow rotation does not unlock the walls. If a long grain-locked part is wider than the sheet, add a correctly oriented sheet. More total area alone cannot fix a long-side mismatch.
