What's New in Flm∴S アイソメmaster
1.0.7
October 27, 2026
新しい部材を多数追加し、切寸の計算をJIS規格の表に合わせて見直しました。 ■ 新しい部材 ・ブラインドフランジ(配管の端に、フランジとふたを一式で) ・プラグ・ブッシング(ねじ込み継手の口に直接) ・ラップジョイント(スタブエンド＋遊合形フランジ) ・伸縮管継手(ベローズ形、単式・複式) ・防振継手(単球形・双球形) ・末端試験弁 ・乾式弁・予作動弁・一斉開放弁 ・送水口(蓋・飾り板の有無も選べます) ・差込み溶接バルブの規格(ステンレス300・鍛鋼800)を選べるように ■ 切寸の見直し ・ねじ込みの径違いチーズ・径違いエルボ・径違いソケットを、JIS B 2301の表から口ごとに計算 ・規格の寸法を小数のまま計算し、切寸の最後だけ丸めるように ・差込み溶接の管端のすき間を設定できるように ・ねじ込みの手前の長さを、全部材共通の設定に ・規格に無い継手の警告を、現行の規格票で判定 ・部材表で、フランジ対を実物の枚数で数えるように ■ 3D表示 ・差込み溶接・ねじ込みの継手やバルブ、フランジのボルト・ナットなどを、JISの寸法・実物どおりの形に作り直しました ・チーズ・クロスの枝の太さをJISどおりに、ちらつきを解消 ■ Mac・トラックパッド ・トラックパッドの2本指で、拡大縮小(ピンチ)と画面の移動ができるように ・数字の欄は、キーボードの数字でも入力できるように ・そのほか、細かな不具合を修正しました

FAQ
What is Flm∴S アイソメmaster used for?
Flm∴S アイソメmaster is a specialized drawing application designed for creating piping isometric drawings (spool drawings). It is intended for use in construction and fabrication sites to streamline the drafting process.
How does Flm∴S アイソメmaster simplify drawing?
It replaces traditional methods like hand-drawing with a scale or launching CAD software. Users can simply tap and place symbols for fittings and valves on a tablet to assemble isometric piping diagrams.
Does Flm∴S アイソメmaster support common piping components?
Yes, it includes frequently used fittings such as elbows (90°/45°), tees, reducers, caps, flanges, and various valves. Users can also specify connection types like welded (BW), threaded (SC), socket weld (SW), and flanged (FL).
How does the automatic cut length calculation work in Flm∴S アイソメmaster?
The app automatically calculates cut lengths based on JIS B2312 and JIS B2002/2080 standards, considering fitting encroachment. It automatically propagates calculations to adjacent sections when a nominal diameter is entered, reducing manual input.
Can I customize the calculated dimensions in Flm∴S アイソメmaster?
While the automatic calculations are based on general standards, they are provided as reference values. You can manually overwrite these values for each section to align with your company's specific standards and adjustments.
What output formats does Flm∴S アイソメmaster offer?
The app allows for vector-based PDF output, ensuring that text and lines remain sharp when enlarged on site. It supports A1, A3, and A4 paper sizes, with options for portrait or landscape orientation, and can include drawing frames and title blocks.
How can I share my drawings made with Flm∴S アイソメmaster?
Drawing data can be saved as project files on a per-spool basis. These files can be easily shared and transferred via iCloud Drive, facilitating collaboration and project continuity.
Is Flm∴S アイソメmaster available on multiple platforms?
Flm∴S アイソメmaster is supported on iPhone and iPad devices, making it accessible for users who prefer Apple's ecosystem for their mobile drafting needs.
