Coohomでは、CADの平面図をアップロードすると、自動的に壁やドア、窓を識別して間取りを生成できます。ここでは、CADファイルを正しくインポートするための要件と、よくある問題の対処方法についてご案内します。要件に沿って準備すれば、認識精度が高まり、設計作業も効率的に進められます。
1. ファイル形式
対応しているのは AutoCADで作成された .dwg / .dxf ファイルのみです。
他のソフトで作成したものは利用できません。
2. ファイルサイズ
サイズの制限はありません。ただし、スムーズな認識のためには 10MB以下(最大でも30MB未満) をおすすめします。
ファイルが大きすぎると、インポートに時間がかかったり、認識に失敗する場合があります。
サイズを縮小する方法の例 • 図面一式がある場合:構造平面図だけを新しいCADファイルにコピーして保存してください。 • 単体の複雑な図面の場合:壁・ドア・窓以外の情報を削除または非表示にしてください。
3. 図面の単位
対応している単位は [mm] / [m] です。インポート時に自動検出されますが、ポップアップ画面で再確認もできます。
推奨:mm単位で作図したファイルをアップロードしてください。例:壁の厚みを測って 240前後 → mm単位、24前後 → cm単位(10倍に拡大してからインポート)。
4. モデル空間で作図してください
認識できるのはモデル空間で描かれた図面のみです。レイアウト空間で描かれたものは正しく読み取れません。
対処方法レイアウト内の平面図を編集モードで開き、新しいCADファイルにコピーして保存してください。
5. 図面サイズ
平面図の外枠は 2.5m × 2.5m以上である必要があります。これより小さい場合は平面図として認識されません。
6. 壁・ドア・窓の描き方
7. 不要な情報を減らしてください
CAD認識の目的は「壁・ドア・窓を正しく復元すること」です。余計な情報が少ないほど認識しやすくなります。
削除・非表示を推奨する要素:
POINT:アップロードできない場合は、一度新しいCADファイルにコピーして保存し、再度お試しください。
