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(dòng)焊接功能，當(dāng)您的光標(biāo)到達(dá)您可以焊接的點(diǎn)時(shí)，該功能會(huì)自動(dòng)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(dòng)將點(diǎn)焊接在一起。

在繪制莫霍面的矢量圖層時(shí)，“焊接”點(diǎn)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(diǎn)的示例，并將繼續(xù)向您展示您可以在 Moho 中進(jìn)行的良好和不良焊接的一些示例。

當(dāng)您在 Moho 中將兩個(gè)點(diǎn)焊接在一起時(shí)，Moho 確實(shí)將這兩個(gè)點(diǎn)合二為一。 這樣做有幾個(gè)原因：首先，將曲線的兩個(gè)端點(diǎn)焊接在一起會(huì)創(chuàng)建一條閉合曲線。 其次，如果兩個(gè)形狀在特定點(diǎn)連接，并且您希望它們?cè)趧?dòng)畫期間保持連接，那么將這些點(diǎn)焊接在一起將保證這兩個(gè)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(diǎn)的方法：手動(dòng)和自動(dòng)。

要使用變換點(diǎn)工具手動(dòng)將兩個(gè)點(diǎn)焊接在一起，首先取消選中該工具的自動(dòng)焊接選項(xiàng)。

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(gè)點(diǎn)拖到另一個(gè)點(diǎn)上，然后按 Enter 鍵。 這是此方法的一個(gè)示例。 盡管您在示例中看不到鍵盤，但請(qǐng)記住，在兩點(diǎn)重疊的那一刻按下了 Enter 鍵。 焊接后，注意兩點(diǎn)如何作為一個(gè)整體移動(dòng)。

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(dòng)的。 要使自動(dòng)焊接起作用，請(qǐng)確保在“變換點(diǎn)”工具處于活動(dòng)狀態(tài)時(shí)工具選項(xiàng)區(qū)域中的“自動(dòng)焊接”復(fù)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(dāng)您將曲線端點(diǎn)拖到另一個(gè)點(diǎn)之上時(shí)，該點(diǎn)會(huì)在可以自動(dòng)焊接時(shí)變?yōu)榫G色。 放開鼠標(biāo)自動(dòng)將點(diǎn)焊接在一起。

這里以自動(dòng)焊接為例。 在這種情況下，沒有按下 Enter 鍵來啟動(dòng)焊接 - 只要松開鼠標(biāo)，兩個(gè)重疊點(diǎn)就會(huì)自動(dòng)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(dòng)焊接的另一個(gè)例子。 請(qǐng)記住，只有曲線端點(diǎn)可以自動(dòng)焊接。 但是，它被焊接到的點(diǎn)不需要是端點(diǎn)：

除了將兩個(gè)點(diǎn)焊接在一起之外，Moho 還可以將一個(gè)點(diǎn)焊接到曲線段的中間。 這可以通過自動(dòng)或手動(dòng)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(diǎn)，但是您為什么要再次焊接點(diǎn)呢？ 主要原因是創(chuàng)建可填充的形狀。 為了用顏色填充形狀，該形狀應(yīng)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(gè)端點(diǎn)焊接在一起，我們可以創(chuàng)建一個(gè)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(diǎn)以創(chuàng)建一條連續(xù)的曲線：

The next case shows the classic case of welding a curve closed to create a fillable ?shape:下一個(gè)案例展示了焊接閉合曲線以創(chuàng)建可填充形狀的經(jīng)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(gè)由幾條曲線組成的形狀。 請(qǐng)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(gè)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(gè)并排排列的圓圈。 圓圈的兩個(gè)側(cè)點(diǎn)已焊接在一起，因此當(dāng)它們?cè)趧?dòng)畫期間四處移動(dòng)時(shí)，它們?nèi)员３诌B接。 如果這些點(diǎn)沒有焊接，像這樣同步移動(dòng)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(gè)圓圈中的不同顏色，自動(dòng)填充是

在將兩個(gè)圓圈焊接到一個(gè)共同點(diǎn)之前關(guān)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(dāng)您將兩個(gè)點(diǎn)焊接在一起時(shí)，其中一個(gè)應(yīng)該是曲線端點(diǎn)。 這并不總是正確的，但大多數(shù)情況下確實(shí)如此。 如果您發(fā)現(xiàn)自己將兩個(gè)點(diǎn)焊接在一起，而端點(diǎn)都不是，請(qǐng)花點(diǎn)時(shí)間考慮焊接是否合適。 這是一個(gè)糟糕的焊接選擇的例子。 假設(shè)您有以下兩種形狀，并且您正在考慮焊接成對(duì)的圓圈點(diǎn)：

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(huì)讓您執(zhí)行這些焊接，但這并不是一個(gè)好主意。 你最終會(huì)創(chuàng)建一個(gè)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(gè)主要形狀：

相反，更好的方法是將兩個(gè)形狀靠得更近，根本不需要任何焊接。 在這種情況下，將兩個(gè)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(diǎn)焊接到下部形狀。 首先，將頂部形狀分開：

然后，將新創(chuàng)建的端點(diǎn)焊接到下部形狀上。 使用這種方法，您最終不會(huì)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：
