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.


  1. 使用选取工具。在笔刷菜单中,您可以点击选取工具(箭头),然后在您的工具盘或工具栏中设定为独立的工具。点击屏幕使用该工具,用法与其他工具类似。
  2. 长按画布中的任意位置同样也能激活选取工具。这是一个非常便捷的方式,让您在绘图过程中无需切换笔刷也能轻易地使用选取功能。
  3. 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.
  4. 如果您想要选取整个图层的内容,可以点击图层缩略图,再次点击该图层缩略图。点击弹出菜单中的选取(箭头图标)可选中整个图层。


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.

  • 在从工具盘中使用选取工具时,只要笔刷处于激活状态,菜单都会一直保留在屏幕上。
  • 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).



  1. 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).
  2. 笔画类型切换键,允许您选取目标笔画的一部分或整体。
  3. 锁定切换键,包括或忽略你在绘画时锁定的任何笔画。
  4. 图层切换键,您可以选取是否只在激活图层中选取或者一次性在所有图层中选取。(“全部”意为在全部图层上选择,“活动”意为仅可套索当前图层内容。)


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.


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.




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.


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.


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.



  • 旋转:允许您旋转您选取的目标。您可以单击打开或者单击关闭。
  • 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.
  • 过滤器:点击此处返回到最初的选取菜单过滤器——元素选择器、套索、颜色吸管。

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.
  • 歪斜:点击两个控点,使用一只手指歪斜整条边。
  • 变形:点击两个控点,使用两只手指捏合或扩散选取内容。




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.


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.
