CXLAYCOLOR画層バージョン 1.0.0AutoCAD で動作確認済み
選んだ図形の画層の色を変える
選択した図形がある画層に新しい色を設定します。オフの画層はオフのままです。
使い方
- CXLAYCOLOR と入力し、図形を選択します。
- 1 から 255 の色番号を入力します(1 は赤、7 は白など)。
- それらの画層の色が変わります。
知っておくこと
- 変わるのは画層の色だけで、図形自身に個別に設定した色には影響しません。
AutoCAD で読み込む
- ファイルを好きな場所に保存します。
- APPLOAD と入力し、ファイルを選んで「ロード」を押します。
- コマンド名を入力します:CXLAYCOLOR。
起動のたびに使うには、同じ画面で「スタートアップ スイート」に追加するか、任意のローダーでフォルダーごと読み込みます。 任意のローダーについて
AutoCAD(フル版)で動作確認しています。AutoLISP を実行できるほかのソフトでも動く場合がありますが、確認はしていません。
