墨壺CADは、墨壺づくりや木工の「型紙」を描くための、いちばんシンプルな2D作図アプリです。 「CADは機能が多すぎてややこしい」 「芯から何mm、という描き方がしたい」 「描いた型紙を、そのままの大きさで印刷したい」 そんな職人の声から生まれました。円と線を、芯(基準点)からの寸法でピタッと描いて、原寸で印刷できます。 ■ 芯から何mmで、ピタッと作図 ・基準点からの位置・長さ・角度・半径を数値で入力 ・端点、交点、円の中心などに自動で吸い付く ・「20, 30, 45」と入れるだけで同心円をまとめて描ける ・数値欄に「360/16」のような計算式も入れられる ■ 型紙づくりに効く機能 ・振り分け:円周上で芯から4mmの点から、中心へ向かう線を引く ・全周等分:16等分など、全ての芯に同じ線を一度に作る ・平行・同心:線や円から指定の距離に同じ形を作る ・角度線:基準の線から何度の線を引く ・複写・移動・回転複写・鏡像(反転) ・トリム(はみ出た部分だけ消す)、延長 ■ 手書きでざっくり → きれいな線と円に 指やApple Pencilでざっくり描くと、まっすぐな線・きれいな円や円弧に整えます。あとから寸法を数値で直せます。 ■ 写真を下絵にしてなぞれる 今ある墨壺や手描きの図を写真で取り込み、2点と実寸を入れるだけで縮尺を合わせて、上からなぞれます。 ■ 寸法線・文字・線の種類 長さ・半径・直径の寸法線、文字、実線・太線・中心線・補助線を使い分けられます。 ■ 塗りつぶし 線で囲まれた部分をタップするだけで色を塗れます。くり抜く部分の目印に。 ■ 数字キーパッドで入力 数値の入力は専用キーパッド。標準キーボードで図面の位置がずれることがありません。 ■ 原寸(1:1)で印刷・PDF ・A4/A3/B5/B4/A5、縦・横に対応 ・AirPrintでそのまま原寸印刷 ・PDFにしてメールやAirDrop、コンビニ印刷にも ・倍率確認用の100mmの線を入れられる ■ 図面はいくつでも自動保存 図面はいくつでも作れて、自動で保存されます。複製や名前の変更も一覧からかんたん。 ■ iPhone と iPad の両方に対応 iPadなら大きな画面とApple Pencilで、より快適に描けます。 ※ 描いた図面や写真は端末の中だけに保存され、外部に送信されることはありません。
