Using Structure= to Mix Templates

The Structure= option swaps only the catalogs from a different template, while keeping the geometry (story heights, spans, offsets) from the named template:

Office, 5F, 4x3, Structure=SRC

• Story height, span, Top_of_Beam_Offset → from Office template
• Column, Beam, Slab sections, Materials → from SRC template

Structure= value	Catalog source
S	Office template
RC	Mansion template
SRC	SRC template
W	W template

Using cut: for L-shapes and Setbacks (v5.7.0)

Templates always generate a full rectangle. Append cut: clauses to void bays at generation time — the affected records are kept with Is_Void=true (nothing is deleted), so a cut can be reverted later in the Layout Editor.

Prompt	Result
Office, 5F, 4x3, cut:NE 1x1	L-shape — the north-east corner bay is voided on all floors
Office, 5F, 4x3, cut:N 4x1@3F+	Setback — the entire north row is voided from 3F up
Office, 5F, 4x3, cut:N 2x1	U-shape — a 2×1 notch centered on the north edge, all floors
Mansion, 10F:3000, 3@6000 x 2@8000, cut:SW 1x1@8F+	RC tower with a SW corner setback from 8F up

See the cut: syntax reference for the full grammar (anchors, floor ranges, out-of-range handling).

更新履歴

バージョン	変更内容
v5.9.0	テンプレート定義の変更なし
v5.7.0	cut: 節による欠き取り生成に対応（テンプレートはフル矩形を生成し、後処理で Is_Void=true を設定）

※ 2026-07-14: 実装と照合し、既定値の表を現行実装に同期しました（School は RC造 3600/7000/8400、Hospital / W の荷重値、SRC / W の小梁 Type_ID、W の材料値、Mansion / W のエイリアス追加）。
