In principle, someone is working on it and there should be a better version in a not so distant future.
If you want to modify this page, please discuss it with the person working on it (see the "history")

Overview

This is part of the Flash tutorials.

Learning goals

Learn to align, stack, combine, break objects

Prerequisites

Flash CS3 desktop tutorial

Flash layers tutorial (first part)

Flash drawing tutorial (at least some of it)

Quality and level

This text should technical people get going. It's probably not good enough for beginners, but may be used as handout in "hands-on" class. That is what Daniel K. Schneider made it for...

It aims at beginners. More advanced features and tricks are not explained here.

Summary

Snapping

Snapping helps to position an object without using the Align Panel.

You can tune the desktop to various snapping modes

• Menu View->Snapping or right-click on the workspace
• Then turn on/off snapping modes or better click on Edit snapping

I usually just have these one:

• Snap align
• Snap to objects
• Horizontal and Vertical Center alignment (will also allow to snap against centeres of objects, otherwise you only can snap against sides)

Edit Snapping

Snap to Objects

• Will snap an object you move against parts of an object. Move slowly...

Snap Align (when snap objects is also on)

• Will snap to dotted lines that will appear

Snap to Grid

• Works when you turn on the Grid with menu View->Grid
• Useful when you do technical drawings for instance.

Snap to Guides

• Same principle as snap to grid. (View->Guides).

Snap to Pixels

• For high precision work. Magnify the stage to at least 400%.

Object spacing does what its name says:

• If horizontal or vertical spacing is bigger it will snap at a certain distance to the edges of other objects
• Note: This means snapping to the centre of a line ! E.g. if distance is 0px and your lines are 5px, your objects will overlap.

Disclaimer: I am not sure what certain combinations do. Here is for example what happens if you drag the red rectangle close to the yellow one in snap align / snap objects mode with zero object spacing:

Align object snapping

Aligning objects

To align objects on the stage you got three solutions:

• Use the align panel (Open it with Window->Align or CTRL-K and dock it next to the Colors panel
• Use menu Modify->Align
• Use the shortcuts (see Flash CS3 keyboard shortcuts)

Various align interfaces of Flash CS3

With the align panel, you can align, distribute or resize a series of selected objects.

There are two fundamental modes:

• Align/distribute against the stage.
• Align an object against the first one you selected, or distribute among the first two selected

The align panel ("to stage" is unticked)

Various align interfaces of Flash CS3

To see what each icon does, move your mouse cursor over it.

These icons represent two things:

1. The line against which alignment or distribution will be made (left, right, middle, top, bottom, etc.)
2. Dark rectangle is the first reference rectangle
3. White rectangle is second, or last plus all the other selected

Match size will change the size (either width, height or both) to the bigger one that is selected (??).

Aligning objects in several frames

You also may align objects in several frames. For example, to align letters in all frames: Click on the Edit multiple frames button in the bar below the timeline.

Select all frames

• Then, you can select the frames you want to edit together by moving the "[" "]" sliders on top of the timeline
• Then select letter-by-letter groups, then use the align pane (Window->Align), but untick To stage.

This tool is quite dangerous, since it's hard to control what happens in each frame. Make sure to save your file before you engage in this ! Also, when you are done, untick the "Edit multiple frames button.

Stacking

When you draw a new object it is drawn on top of the others.

You can move forward or backwards any select object(s)

• Use the right-click->Arrange menu.

CTRL+Up Arrow - Move Ahead

CTRL+Down Arrow - Move Behind

Grouping

Turning shapes into objects

To group several shapes into an object:

• Menu Modify->Combine Objects->Union

To break apart an object:

• Menu Modify->Break Apart or Right-click->Break Apart or CTRL-B

Creating a new object from others

Menu Modify->Combine Objects lets you combine objects in several ways:

• Union as above: It will create a new object and respect the stacking (i.e. as you see it on the stage)
• Intersect will only the take the common area
• etc ...

To break apart an object:

• Menu Modify->Break Apart or Right-click->Break Apart or CTRL-B
• The result will be shapes, not the orginal objects.

Grouping Objects

To group several objects:

• Select these
• Hit CTRL-g or menu Modify->Group

To ungroup an object

• Select it
• Hit CTRL-SHIFT-g or menu Modify->UnGroup

Note: grouped objects can be animated with motion tweens (simple, editable objects cannot!). So once you have a goup in a tween, you can't ungroup anymore). Except by killing the tween. I rather suggest using symbols for motion animation anyhow.

Grouping Objects into a symbol

• Select several objects
• Right-click->Convert to Symbol or hit CTRL-F8

Then you have to choose and name and select the type:

• "Graphic" means a graphic (like an named group of objects)
• "Button" will create a button symbol (you then can fine tune the button frames)
• "Movie Clip" will allow you to treat it as an animation, double click on it to edit...

More

• If you draw a lot, you may want to print the list of Flash CS3 keyboard shortcuts
• There is more stuff in the Modify Menu, but that's its enough for now ... :)
