選取

Concepts is a vector-based app, which gives you the powerful freedom to pick up and move, tweak or change any stroke at any time, even after it’s drawn. It allows you to make changes to your designs with minimal effort - instead of redrawing an entire project, you can just select what needs to be adjusted and change it. Perfect for design iterations, reorganizing mind-maps, or preparing materials for clients after feedback, Selection frees you to accomplish more.

我們有4種可以選中一條或多條線條的方法：

使用選取工具。在筆刷選單中，你可選擇選取工具（箭頭圖標），然後將它在工具轉輪/欄上設定為單獨的工具。點按熒幕使用該工具，用法與其他工具一樣。

按住畫布上的任意位置，也可以激活選取工具。這是一個快捷方式，讓您使用筆刷的過程中無需切換工具。
If you’re using an Apple Pencil, configure your Finger Action to Select (Settings → Gestures). Your finger will work as the Selection tool while the Apple Pencil follows your selected preset in the tool wheel.
If you want to select all strokes on a single layer, you can tap on the active layer to open the Layer Selection pop-up. Tapping the cursor icon will select everything on that layer.

選取選單

Once you’ve activated selection by any of the above options, you’ll find a popup at the bottom of the screen. This is your Selection menu. The Selection menu helps you to filter the strokes you’d like to select from, so whenever you select something, this menu will hang around.

在工具轉輪中使用選取工具時，激活狀態時，選單會一直保留在熒幕上。
When Selecting via the tap+hold, the menu will remain for as long as your finger rests on screen. With a second finger, you can toggle the menu buttons to set your filters (we’ll talk about those below).

Item Picker, Lasso, Color Picker and their respective popups.

在選取選單中，根據激活的選項，從左至右有：

A Selection Type toggle, for which selection method you’d like active. Tap it to toggle between Item Picker (single item selection, with the ability to add or subtract strokes individually), Lasso (multi-select using drag to lasso your strokes), and Color Picker (select color and vector properties from strokes).
筆劃類型切換鍵，允許你選取目標筆劃的一部分或全部。
鎖住切換鍵，包含或忽略繪圖時鎖住的任何筆劃。
圖層切換鍵，可選擇在活動圖層或所有圖層中選取。

套選

On the first, left-hand toggle is your Lasso. The lasso allows you to select items by dragging your finger across or around your strokes. Whatever the blue lasso touches will be part of your selection. Lasso again to subtract from the selection.

If you lasso a selection and decide you want to add further individual strokes, toggle to Item Picker via the Filters button and continue making your selections.

元素選取器

If you tap the Selection Type toggle again, you’ll find the Item Picker. This is a single item selection mechanism that allows you to add and subtract individual strokes to your selection.

將小十字拖到筆劃上，若需要選取單根線條，鬆手即可；若需要選取多根線條，使用另一隻手指點按熒幕來選取筆劃，然後移動到其他的筆劃上，重複該操作。

要使用元素選取器，只需將手指或觸控筆放在熒幕上，指尖或筆尖就會顯示小的十字或（+）。

When you touch the crosshairs to a stroke, a circle will appear, telling you it has located a stroke. Tap the screen to validate the stroke, and lift your finger from the screen. The stroke will be selected.

To add strokes to your selection, just drag the crosshairs to your next stroke and tap the screen to select it. It doesn’t matter whether you have lifted your finger from the screen or not, you can select as many strokes as you’d like.

如果想從選取內容中移除筆劃，將小十字拖到已選取的筆劃上。會看到小十字變成減號（—）。點按熒幕接受移除。

Tip: While using the selection tool, toggle between the Item Picker and Lasso by putting another finger on screen. This changes the selection mode. Lift the finger to return to the other mode.

Color Picker

If you tap through the Selection toggles from Lasso to Item Picker, the third toggle is the Color Picker. This is a vector color picker with a few more capabilities than standard color pickers in other apps. It allows you to select and remember color, brush and stroke properties, and set them to your tools. Read more about it in the Color section.

調整選取內容

當你選取一根或一組筆劃後，可以看到熒幕底部的選取選單出現更多有用的切換鍵。

旋轉：可以旋轉所選內容。點按開啟或禁用。
Scale / Stretch / Off. Toggle between these to scale strokes (changes the stroke width while scaling the selection), stretch strokes (maintains the original stroke width while scaling the selection), or lock your strokes from scaling or stretching.
Filters. Tap this to return to the original Selection menu filters — Item Picker, Lasso, Color Picker.

You can use a two finger gesture to scale and rotate selections.

You can also do an exact angle rotation of your selection using the angle field on the status bar at the top of the canvas. Tap+hold the angle field to bring up a keyboard and a set of presets. Tap an angle value from the presets or type in your custom degrees value. Objects will rotate clock-wise. It helps to lock your rotation toggle on the selection menu first to avoid turning it again when moving the object.

You can also use the four corner handles around a selection to adjust the selection. These handles are your Control Points. You can tap, then drag a single point to scale/stretch the selection. Or you can tap a corner point or two and distort, skew and warp your selection just by pulling with one or two fingers. These are excellent for tweaking size and shape to make your drawing proportions right. They’re also helpful for aligning strokes, text or other images into your sketch’s perspective.

Scale/stretch. Drag one of the corner points to resize the selection. Put another finger on screen to lock the aspect ratio while resizing.
Distort. Tap one corner and drag anywhere on screen to pull it around.
Skew. Tap two corners at once, and use one finger to pull the entire side about.
Warp. Tap two corners at once, and use two fingers to either pinch or expand your selection. This makes your drawing act like the Star Wars credits.

May the Force be with you.

選取彈出選單

Above the selection box is a Selection popup. This has many useful features you might use to adjust your strokes.

Clipboard. The clipboard copies your selection to your main device’s clipboard, just like when you copy text from an email or link. Tap Paste in any email, message, document editor etc. to paste in a transparent PNG version of your selection. Inside the app, you can find the clipboard from your Gallery, at the top of your current object library, from inside the Import menu → Imports, or just by a tap+hold on the screen. You can also attach colors from other apps to your clipboard, and access them on the Color wheel.

Duplicate. Anything you select, you can also copy, as many times as you’d like. Just touch Duplicate and it will create an exact match for fast iterations. Drag the duplicate to a new layer to keep or hide your old selection, and iterate on the new.

Group. This chain link button allows you to group all items inside your selection together, into a single “object.” You can then select the entire object with a single tap, instead of having to re-select multiple strokes. To separate them again, just select the object and tap the button again to ungroup them.

Lock. The Lock button locks your selection from all other selections and adjustments you might make in the future. You can access it again by selecting and unlocking it, or by changing the Lock filter on the Selection menu.

Delete. The best way to erase a vector stroke is to delete it. You can use the Slice tool to erase and Mask tools to hide strokes, but the quickest way to remove an entire stroke is to just select and delete it. Of course, you can Undo.

Flip and Mirror. The final two buttons allow you to flip your selection from side to side, or to mirror it vertically. These are great for creating reflections and shadows, as well. If you want to rotate your selection, tap the measurement button in the Status Bar and choose a rotation value.

Highlight Selection

In the Settings → Gestures menu, you'll find an option to "Highlight Selection". Tap the checkbox to toggle this on or off as you prefer.

Highlight Selection allows you to clearly see the strokes you have selected. When you have an active selection, the selection maintains its actual colors and everything else is greyed. The active selection also pops to the front, meaning that if the stroke you selected is behind other strokes, it will be presented on top for as long as the selection is active. If you turn off Highlight Selection, the only thing differentiating the selection from other strokes is the bounding box.

You can also use Highlight Selection with the Nudge tool. When it’s turned on, you’ll see both before and after strokes as you nudge lines on your screen, with the original stroke slightly greyed out. Turn it off to only see the adjusted stroke.

You can turn Highlight Selection on or off in Settings → Gestures.
