Tutorial 2.1: Welding

【資料圖】

As you learned in the Quick Start tutorials, Moho features an Auto Weld feature ?that automatically welds shapes and segments together when your cursor reaches ?a point that you can weld to. However, there are cases where you may want to ?manually weld points together.?

When drawing in Moho’s vector layers, the concept of “welding” points is very ?important. These tutorials will show you examples of how (and why) points can be ?welded, and will go on to show you some examples of good and bad welds you ?can do in Moho.?

When you weld two points together in Moho, Moho really is combining those ?two points into one. There are a couple reasons to do this: First, welding the two ?endpoints of a curve together creates a closed curve. Second, if two shapes join ?up at a particular point, and you want them to remain joined during an animation, ?then welding those points together will guarantee that those two shapes will remain ?joined.

正如您在快速入門教程中所了解的，Moho 具有自動焊接功能，當您的光標到達您可以焊接的點時，該功能會自動將形狀和線段焊接在一起。 但是，在某些情況下，您可能希望手動將點焊接在一起。

在繪制莫霍面的矢量圖層時，“焊接”點的概念非常重要。 這些教程將向您展示如何（以及為什么）焊接點的示例，并將繼續向您展示您可以在 Moho 中進行的良好和不良焊接的一些示例。

當您在 Moho 中將兩個點焊接在一起時，Moho 確實將這兩個點合二為一。 這樣做有幾個原因：首先，將曲線的兩個端點焊接在一起會創建一條閉合曲線。 其次，如果兩個形狀在特定點連接，并且您希望它們在動畫期間保持連接，那么將這些點焊接在一起將保證這兩個形狀將保持連接。

How to Weld Points

There are two ways to weld points in Moho: manually and automatically.?

To manually weld two points together with the Transform Points tool, first ?uncheck the Auto-weld option for the tool.

Moho有兩種焊接點的方法：手動和自動。

要使用變換點工具手動將兩個點焊接在一起，首先取消選中該工具的自動焊接選項。

Drag one point on top of the other and press the Enter key. Here’s an example of ?this method. Although you can’t see the keyboard in the example, keep in mind ?that the Enter key was pressed at the moment when the two points overlap. After ?welding, notice how the two points move as one.

將一個點拖到另一個點上，然后按 Enter 鍵。 這是此方法的一個示例。 盡管您在示例中看不到鍵盤，但請記住，在兩點重疊的那一刻按下了 Enter 鍵。 焊接后，注意兩點如何作為一個整體移動。

The second method of welding is automatic. For automatic welding to work, be ?sure that the Auto-weld checkbox is turned on in the tool options area when the ?Transform Points tool is active:

第二種焊接方法是自動的。 要使自動焊接起作用，請確保在“變換點”工具處于活動狀態時工具選項區域中的“自動焊接”復選框已打開：

Using this method, when you drag a curve endpoint on top of another point , the ?point turns green when it can be welded automatically. Let go of the mouse to ?automatically weld the points together.?

Here’s an example of automatic welding. In this case, the Enter key was not pressed ?to initiate the weld - as soon as the mouse is released, the two overlapping points ?are automatically welded together.

使用此方法，當您將曲線端點拖到另一個點之上時，該點會在可以自動焊接時變為綠色。 放開鼠標自動將點焊接在一起。

這里以自動焊接為例。 在這種情況下，沒有按下 Enter 鍵來啟動焊接 - 只要松開鼠標，兩個重疊點就會自動焊接在一起。

Here’s another example of automatic welding. Remember that only a curve ?endpoint can be automatically welded. However, the point that it is welded to does ?not need to be an endpoint:這是自動焊接的另一個例子。 請記住，只有曲線端點可以自動焊接。 但是，它被焊接到的點不需要是端點：

除了將兩個點焊接在一起之外，Moho 還可以將一個點焊接到曲線段的中間。 這可以通過自動或手動焊接方法來完成。

Why to Weld Points

OK, so that covers welding points, but why do you want to weld points again? The ?main reason is to create fillable shapes. In order to fill a shape with color, that shape ?should be completely closed, either by overlapping lines or by shapes that are ?welded together so that there are no gaps in the shape that you want to fill.

好的，這樣就涵蓋了焊接點，但是您為什么要再次焊接點呢？ 主要原因是創建可填充的形狀。 為了用顏色填充形狀，該形狀應該完全封閉，通過重疊線或焊接在一起的形狀，以便在要填充的形狀中沒有間隙。

By welding the two endpoints together, we can create a closed shape that can ?then be filled:

通過將兩個端點焊接在一起，我們可以創建一個可以填充的封閉形狀：

Examples of Good Welding

Let’s look at some examples of good welding choices. First, the following two points ?could be welded to create a single, continuous curve:讓我們看一些良好的焊接選擇示例。 首先，可以焊接以下兩點以創建一條連續的曲線：

The next case shows the classic case of welding a curve closed to create a fillable ?shape:下一個案例展示了焊接閉合曲線以創建可填充形狀的經典案例：

Next, we show a shape made up of several curves. Notice that a closed, fillable ?shape does not need to be made up of a single curve. The shape below, after ?welding, is made up of three curve segments, but is still closed and can be filled with ?color:

接下來，我們展示一個由幾條曲線組成的形狀。 請注意，封閉的可填充形狀不需要由單條曲線組成。 下面的形狀，焊接后，由三個曲線段組成，但仍然是封閉的，可以用顏色填充：

Finally, the example below shows two circles lined up side-by-side. The two side ?points of the circles have been welded together so that when they move around ?during an animation they remain joined. If those points were not welded, moving ?them in sync like this would require a lot of extra work.

最后，下面的示例顯示了兩個并排排列的圓圈。 圓圈的兩個側點已焊接在一起，因此當它們在動畫期間四處移動時，它們仍保持連接。 如果這些點沒有焊接，像這樣同步移動它們將需要大量額外的工作。

To maintain the separate colors in the two circles, Auto Fill is ?turned off before welding the two circles together at a ?common point.

為了保持兩個圓圈中的不同顏色，自動填充是

在將兩個圓圈焊接到一個共同點之前關閉。

Typically, when you weld together two points, one of them should be a curve ?endpoint. This isn’t always true, but most often it is. If you find yourself welding ?together two points and neither is an endpoint, take a moment to think whether the ?weld is appropriate. Here’s an example of a bad choice of welding. Suppose you ?had the following two shapes and you were considering welding the pairs of circled ?points:

通常，當您將兩個點焊接在一起時，其中一個應該是曲線端點。 這并不總是正確的，但大多數情況下確實如此。 如果您發現自己將兩個點焊接在一起，而端點都不是，請花點時間考慮焊接是否合適。 這是一個糟糕的焊接選擇的例子。 假設您有以下兩種形狀，并且您正在考慮焊接成對的圓圈點：

Although Moho will let you perform those welds, it isn’t really a good idea. What you ?would end up creating is a shape with lots of little holes in it. Along the section of ?curves that you welded together are little bubbles that make it impossible to fill the ?two main shapes:

盡管 Moho 會讓您執行這些焊接，但這并不是一個好主意。 你最終會創建一個有很多小洞的形狀。 沿著焊接在一起的曲線部分是小氣泡，無法填充兩個主要形狀：

相反，更好的方法是將兩個形狀靠得更近，根本不需要任何焊接。 在這種情況下，將兩個形狀焊接在一起沒有任何好處。

Another approach in this situation would be to cut the top shape apart with ?the Delete Edge tool and then weld the remaining endpoints to the lower ?shape. First, cut the top shape apart:

在這種情況下，另一種方法是使用刪除邊緣工具將頂部形狀切開，然后將剩余的端點焊接到下部形狀。 首先，將頂部形狀分開：

然后，將新創建的端點焊接到下部形狀上。 使用這種方法，您最終不會得到一條全部焊接在一起的雙曲線。 生成的形狀更干凈，更易于使用：
