User reviews

バグなのか

三角形の図面しか出てこない

ARとか言うのが使えない

わざわざ購入して使えんやつあるなら書いといて欲しい
ARのボタン押したら画面真っ黒で何も使えない
有料にするなら全部使えるようにして欲しい

エルボの展開図

エルボ(エビ管)の展開図が全く異なる結果のですが、、、
(メールでも質問しましたがなかなかお返事いただけないのでこちらでもお伺いします)

教えて下さい。

芯ずれのホッパーについて質問です。 仮に32等分した時に16の位置で折り返しだと思うのですが数字が違うのは何故でしょうか? レビューすぐ消されてしまいますが再度質問させていただきます。

Response from developer

芯がずれたホッパーを円錐(Corn)の展開図として考えますと、芯がずれる方向で半分に割った際の展開図が、自然と反対側の展開図と同じ寸法になります。そのため、分割する数を展開図半分で、32等分としております。 一方、角丸(Rounded)形状の展開図の場合、円周上の32の分割点のうち、0°、90°、180°、270°の4点については、4角形の側面の4点のうち2箇所から線を引く必要があります。そのため、計算結果として円周の32等分に対し、線の寸法が35点出力されることになります。さらに、端部をつなぐ接合部の長さについては、上部の画像内に寸法を表示しております。

合わない

FAQ

What types of triangles can Triangle3 calculate?

Triangle3 can calculate both right triangles and unequal triangles. The app allows users to input dimensions for two right triangles and three unequal triangles for calculations.

Does Triangle3 have ads?

No, Triangle3 does not contain advertisements. It is a paid application that offers an ad-free experience for its users.

What complex shapes can Triangle3 develop?

Triangle3 can develop various complex shapes including cones (with misalignment), diagonal cuts, R-cuts, T-pipes, shrimp tubes, rounded corners (with eccentricity), hopper eccentricity, pipes from mirror plates, connecting pipes to tapered pipes, screw wings, and calculate PCD.

What devices is Triangle3 compatible with?

Triangle3 is compatible with iPhone, iPod, and Apple Watch devices. This allows for calculations and visualizations across multiple Apple platforms.

How does the AR feature in Triangle3 work?

The AR feature in Triangle3 allows for the display of specific developments, such as floor plans, in full size using augmented reality. This helps visualize the calculated shapes in a real-world context.

What is the age rating for Triangle3?

Triangle3 has an age rating of 4+. This indicates that the content is generally suitable for all ages, with minimal or no mature content.

How often is Triangle3 updated?
