Create and modify shapes using Pen and shape tools and copy paths into After Effects from Illustrator and Photoshop.

You create a shape layer by drawing in the Composition panel with a shape tool or the Pen tool. You can then add shape attributes to existing shapes or create shapes inside that shape layer. By default, if yous draw in the Composition panel when a shape layer is selected, you create a shape within that shape layer, in a higher place the selected shapes or group of shapes. If you lot draw in the Limerick panel using a shape tool or Pen tool when an image layer other than a shape layer is selected, you create a mask. For more than information, see Create masks in After Effects.

Shortcuts for Shape tool is Q, and Pen Tool shortcut is G.

Before drawing in the Composition panel to create a shape layer, printing F2 and deselect all layers.

Usually, a new shape has a fill and a stroke that correspond to the Fill and Stroke settings in the Tools console at the time that the shape is drawn. You lot can employ the aforementioned controls in the Tools panel to change these attributes for a selected shape afterwards information technology has been drawn. Shapes created from text are created with fills and strokes that match the fills and strokes of the original text.

Convert Vector Fine art Footage to Shape

Yous can create a shape layer from a vector art footage layer, and and so modify it. With the ability to bevel and extrude objects in Later on Effects, you can extrude the artwork, for example, extruded logos. For more than information, run into Extruding text and shape layers.

To convert a vector art footage layer to shape layer, chooseLayer > Create >Create Shapes from Vector Layer. A matching shape layer appears above the footage layer, and the footage layer is muted.

• Non all features of Illustrator files are currently preserved. Examples include: opacity, images, and gradients.
• Converted shapes ignore PAR overrides specified in the Interpret Footage dialog box.
• Gradients and unsupported types may testify as 50% gray shapes.
• Files with thousands of paths may import slowly without feedback.
• The carte du jour command works on a single selected layer at a time.
• If yous import an Illustrator file as a composition (multiple layers), y'all cannot convert all those layers in one pass. However, you can import the file as footage, and and so use the command to catechumen the unmarried footage layer to shapes.

To actuate and wheel through the shape tools, press Q.

A polygon is a star without an Inner Radius or Inner Roundness property. Then, the proper name of the shape created for a polygon or a star is the same: polystar.

You can create a mask by dragging with a shape tool on a selected layer in the Composition panel or Layer panel. You tin create a shape by dragging with a shape tool on a selected shape layer in the Limerick panel. If you drag with a shape tool in the Composition console with no layer selected, you lot create a shape on a new shape layer.

To draw a mask on a shape layer, click the Tool Creates Mask button in the Tools panel with a shape tool active.

When you create a shape by dragging with a shape tool in the Limerick console, yous create a parametric shape path. To instead create a Bezier shape path, printing the Alt (Windows) or Option (Mac Bone) key before you click to brainstorm dragging. You can release the key before you complete the drag operation. All mask paths are Bezier paths. (Come across About shapes and shape layers.)

Dragging starts when you click in the Composition console or Layer panel to brainstorm drawing, and ends when y'all release the mouse button. Pressing modifier keys at different times during a single dragging operation achieves different results:

• To reposition a shape or mask as y'all are drawing, hold the spacebar or the middle mouse push while dragging.

• To scale a circle, ellipse, foursquare, rounded square, rectangle, or rounded rectangle around its center while drawing, hold the Ctrl (Windows) or Control (Mac Os) fundamental afterward you begin dragging. Don't release the fundamental until you have released the mouse push to finish cartoon.

• To abolish the drawing operation, press Esc.

Each shape tool retains the settings of the well-nigh contempo cartoon operation with that tool. For example, if yous describe a star and modify the number of points to be x, then the next star that you describe volition also have ten points. To reset settings for a tool and create a shape with the default settings, double-click the tool in the Tools panel. (Run across Create a shape or mask the size of the layer.)

Draw rectangles, rounded rectangles, squares, and rounded squares

2.  (Optional) If drawing a rounded rectangle or rounded foursquare, do the following earlier releasing the mouse button:

• To increase or decrease the corner roundness, press the Upwards arrow key or the Down arrow primal, or roll the mousewheel forward or backward.
• To set corner roundness to the minimum or maximum, press the Left arrow cardinal or the Right pointer central.

3.  Finish drawing past releasing the mouse button. If drawing a square or rounded square, release the Shift cardinal afterward releasing the mouse push.

Squares are created to be foursquare according to the pixel aspect ratio of the composition. If the pixel attribute ratio of the composition is not 1, and so squares appear square in the Limerick panel only if the Toggle Pixel Attribute Ratio button is selected at the bottom of the Limerick panel.

Draw ellipses and circles

1. Select the Ellipse tool, and do ane of the following:
   • To draw an ellipse, drag diagonally.
   • To describe a circumvolve, Shift-drag diagonally.
2. Release the mouse to finish drawing. If drawing a circle, release the Shift key after releasing the mouse button.

Circles are created to be circular co-ordinate to the pixel attribute ratio of the composition. If the pixel aspect ratio of the composition is not 1, then circles appear circular in the Composition panel only if the Toggle Pixel Aspect Ratio button is selected at the lesser of the Composition panel.

Draw polygons and stars

2.  (Optional) Exercise the following before releasing the mouse button:

• To add or remove points, press the Upward pointer key or the Down arrow fundamental, or roll the mouse wheel forwards or astern.
• To increase or decrease the outer roundness, press the Left arrow cardinal or the Correct pointer key.
• To keep the inner radius of a star constant as yous move the mouse to increase the outer radius, concur the Ctrl (Windows) or Command (Mac OS) primal.
• To increase or subtract the inner roundness of a star, press the Page Up key or the Page Downward fundamental.

3.  Release the mouse push button to finish cartoon. If Shift-dragging to prevent rotation, release the Shift cardinal later on releasing the mouse push button.

You can create a Bezier mask using the Pen tool on a selected layer in the Composition panel or Layer console. You tin can create a shape with a Bezier path using the Pen tool on a selected shape layer in the Composition panel. If you draw with the Pen tool in the Composition console with no layer selected, you create a shape on a new shape layer.

Creating a RotoBezier path is similar to creating a transmission Bezier path. The primary deviation is that direction lines for vertices and curvature for path segments are automatically calculated.

With the Pen tool selected and the RotoBezier option deselected in the Tools panel, click in the Composition panel where you desire to place the first vertex.

Click where you lot want to place the side by side vertex. To create a curved segment, elevate the direction line handle to create the curve that you want.

To reposition a vertex subsequently you've clicked to identify it only before you've released the mouse push, concord the spacebar while dragging.

The final vertex that you lot add appears as a solid square, indicating that information technology is selected. Previously added vertices become hollow, and deselected, every bit you add together more vertices.

Repeat footstep ii until you lot are gear up to complete the path.

Complete the path past doing 1 of the following:

• To shut the path, identify the arrow over the beginning vertex and, when a closed circumvolve icon appears adjacent to the pointer , click the vertex. You lot can likewise close a path by double-clicking the terminal vertex or choosing Layer > Mask And Shape Path > Closed.
  
• To leave the path open, activate a different tool, or printing F2 to deselect the path.

The simplest path that yous tin can draw with the Pen tool is a straight line, fabricated past clicking with the Pen tool to create two vertices. By continuing to click, you create a path made of straight-line segments continued by corner points.

Identify the Pen tool where you want the directly segment to brainstorm, and click to place a vertex. (Exercise not drag.)



Clicking with Pen tool creates straight segments.

Click over again where y'all desire the segment to end. (Shift-click to constrain the angle betwixt segments at the corner point to a whole multiple of 45°.)

Continue clicking to set vertices for additional straight segments.

You create a curved path segment by dragging management lines. The length and management of the management lines decide the shape of the curve.

Shift-elevate to constrain the angle of the management lines to whole multiples of 45°. Alt-drag (Windows) or Option-elevate (Mac Bone) to alter only the outgoing direction line.

1.  Place the Pen tool where you lot desire the curve to begin, and agree the mouse button down. A vertex appears, and the Pen tool pointer changes to an arrowhead.

ii.  Drag to modify the length and direction of both direction lines for a vertex, and and then release the mouse button.

3.  Place the Pen tool where y'all want the curved segment to end, and do one of the following:

• To create a C-shaped curve, elevate in the direction opposite from the direction that you dragged the previous direction line, so release the mouse button.

4.  Continue dragging the Pen tool from different locations to create a serial of smooth curves.

Create a shape of the size of the layer

Select the destination for the new shape:

• To create a shape on an existing shape layer, select the shape layer.

• To create a shape on a new shape layer with the dimensions of the composition, deselect all layers by pressing F2.

• To supersede a shape path, select the shape path (not the group) in the Composition panel or Timeline panel.

Create shapes from text characters

Utilise Create Shapes From Text to extract the outlines for each character, create shapes from the outlines, and put the shapes on a new shape layer. Yous can then employ these shapes every bit you would any other shapes.

Use Create Masks From Text to extract the outlines for each character, create masks from the outlines, and puts the masks on a new solid-color layer. You can then utilize these masks as you would whatever other masks.

Some font families, such as Webdings, include characters that are graphical images, rather than text. Converting text from these font families tin be a skilful style to get started with simple graphical elements in shape layers.

Select the text to catechumen to shapes:

• To create shapes for all characters in a text layer, select the text layer in the Timeline panel or Composition panel.
• To create shapes for specific characters, select the characters in the Limerick panel.

• Choose Layer > Create Shapes From Text.
• Correct-click (Windows) or Control-click (Mac OS) the layer or text and choose Create Shapes From Text from the context carte.

• The Video switch for the text layer is turned off.
• The new shape layer is created at the top of the layer stacking society. The new layer contains one shape group for each selected graphic symbol, plus fill and stroke properties that match the fills and strokes of the text.
• For characters that consist of chemical compound paths—such as i and e—multiple paths are created and combined with the Merge Paths path operation.
• Effects, masks, layer styles, and keyframes and expressions for properties in the Transform property group of the text layer are copied to the new shape layer or solid-color layer.

Re-create a path from Illustrator or Photoshop

You lot can re-create a path from Illustrator or Photoshop and paste it into After Furnishings as a mask path or shape path.

To make the data copied from Illustrator uniform with After Effects, the AICB option must exist selected in the Files & Clipboard section of the Adobe Illustrator Preferences dialog box.

For a path imported from Photoshop to be scaled correctly, the Photoshop document must take a resolution of 72 dpi. 72 dpi is the Resolution setting of documents created in Photoshop using a Flick & Video preset.

Y'all can too utilize a copied Illustrator or Photoshop path as an Later Furnishings motility path. See Create a movement path from a mask, shape, or paint path for more information.

Path fatigued in Adobe Illustrator (left) and pasted into After Furnishings as a mask (right)

In Illustrator or Photoshop, select an unabridged path, and then choose Edit > Copy.

In After Furnishings, do one of the post-obit to define a target for the paste functioning:

• To create a mask, select a layer.

• To replace an existing mask path or shape path, select its Path property.

To paste a path as a shape path, you must select the Path property of an existing shape in a shape layer. This selection tells Later on Effects what the target of the paste operation is; if the target isn't specified in this way, After Effects assumes that the target is the entire layer and therefore draws a new mask. If there is no Path property—peradventure because the shape layer is empty—then you tin draw a placeholder path with the Pen tool and then paste the path from Illustrator into the placeholder path.

Cull Edit > Paste. If yous paste multiple paths into a shape path, the kickoff path goes into the shape path, and the remaining paths are pasted into new mask paths.

Create a shape from a motionpath

You can re-create position keyframes, anchor bespeak keyframes, or an event control point'due south position keyframes and paste those keyframes into a selected mask path or shape path. When you create mask paths or shape paths from move paths, make sure that you copy keyframes from a unmarried Position property only—practise not copy the keyframes of whatever other property.

Draw a movement path with Movement Sketch and and then paste the path into a mask path or shape path.

The movement path of the spaceship copied to the groundwork layer, and blithe

Create a shape path from a motion path

In the Timeline panel, click the proper noun of the Position property or Anchor Point property from which you lot want to copy the motion path. (This selects all keyframes. To select simply some of the keyframes of a motion path, Shift-click them.)

To create a shape layer, press F2 to deselect all layers, and then click in the Limerick panel with the Pen tool to create a single-bespeak Bezier path.

Printing SS to reveal the Path property for the shape. Click the name of the Path property into which to paste the keyframes from the motion path.

Indistinguishable a shape grouping while transforming

When a shape group is selected in group selection mode, yous can duplicate the group while moving, rotating, or scaling information technology in the Composition console.

Agree the Alt (Windows) or Option (Mac Os) key as yous elevate to transform a group.

The pointer changes to a duplication arrow ( or ) as you concord the key and place the pointer virtually the group transform box.
