    Kevin Kennedy: Welcome to Day #19
  • 00:00:01
    of Learn Fusion 360 in 30 Days.
  • 00:00:03
    I’m Kevin Kennedy,
  • 00:00:04
    and today we’ll look at creating User
  • 00:00:06
    Parameters, copy and pasting components,
  • 00:00:08
    and more, as we create a Parametric box.
  • 00:00:12
    In Fusion 360, activate the “Change
  • 00:00:14
    Parameters” dialog from the Modify menu.
  • 00:00:18
    Parameters allow you to create
  • 00:00:19
    equations and relationships to control
  • 00:00:21
    the size of your Fusion 360 designs.
  • 00:00:24
    By assigning names to the
  • 00:00:25
    equations, we can reuse the
  • 00:00:27
    parameters throughout the design.
  • 00:00:29
    Let’s create a new Parameter
  • 00:00:30
    for our Box’s width.
  • 00:00:32
    Select the plus symbol
  • 00:00:33
    to add a new parameter.
  • 00:00:36
    We’ll type the name “BoxWidth.”
  • 00:00:38
    Note that spaces are not
  • 00:00:39
    allowed in the parameter names.
  • 00:00:41
    You can utilize camelCase,
  • 00:00:43
    snake_case, or PascalCase.
  • 00:00:46
    The unit of measurement will
  • 00:00:47
    default to your document units.
  • 00:00:49
    However, we can also create parameters
  • 00:00:51
    for other units of measure, including
  • 00:00:54
    degrees, volume, mass, and so much more.
  • 00:00:58
    I’ll set the expression to 50mm, which
  • 00:01:00
    will be the starting width of the box.
  • 00:01:03
    We’re also able to plug
  • 00:01:04
    in optional comments.
  • 00:01:06
    Comments are helpful to remind
  • 00:01:07
    yourself of items later or
  • 00:01:09
    when collaborating with others.
  • 00:01:11
    After selecting OK, you’ll
  • 00:01:13
    find the BoxWidth parameter
  • 00:01:14
    in the “User Parameters” list.
  • 00:01:17
    Let’s create a second User
  • 00:01:19
    Parameter called “BoxHeight”
  • 00:01:20
    with a value set to 40mm.
  • 00:01:26
    We can now close the dialog.
  • 00:01:28
    Our parameters are now ready to be called
  • 00:01:30
    through any sketch or modeling commands.
  • 00:01:34
    Let’s start with a new
  • 00:01:35
    component called “Box Bottom.”
  • 00:01:39
    Once active, we’ll start with a new
  • 00:01:41
    sketch on the bottom origin plane.
  • 00:01:45
    Activate the 2-point rectangle and select
  • 00:01:47
    the origin point to start the sketch.
  • 00:01:51
    For both dimensions, we’ll enter
  • 00:01:52
    the “BoxWidth” user parameter.
  • 00:01:55
    Notice the parameter name appears
  • 00:01:56
    after typing the letter “B”.
  • 00:01:58
    We can select the correct one without
  • 00:02:00
    having to type out the full name.
  • 00:02:03
    Complete this for both dimensions,
  • 00:02:05
    which fully defines our sketch.
  • 00:02:09
    Let’s also practice good parametric
  • 00:02:11
    design etiquette by renaming
  • 00:02:12
    our sketch in the Browser.
  • 00:02:18
    We’re now ready to Extrude our sketch.
  • 00:02:21
    Once selected, we’ll use the
  • 00:02:23
    BoxHeight user parameter.
  • 00:02:25
    However, we’re only creating the bottom
  • 00:02:27
    of the box, so let’s divide this by 2.
  • 00:02:31
    Notice the height adjusted to be only
  • 00:02:33
    20mm, half of the overall height.
  • 00:02:37
    We’ll use the Shell command
  • 00:02:38
    to hollow out the box.
  • 00:02:40
    Activate Shell and select
  • 00:02:42
    the top planar face.
  • 00:02:45
    Fusion 360 also allows us to
  • 00:02:47
    create ‘parameters on the fly’.
  • 00:02:49
    Start by typing the desired parameter
  • 00:02:51
    name, such as “WallThickness.”
  • 00:02:53
    We then have to put the equal
  • 00:02:54
    sign, followed by the value.
  • 00:02:57
    Let’s do “WallThickness” equals 2.
  • 00:03:01
    Select OK to confirm the Shell operation.
  • 00:03:06
    Let’s open the parameters dialog.
  • 00:03:09
    Notice parameters created on the fly
  • 00:03:11
    are listed in the Favorites section
  • 00:03:13
    and not the User Parameters section.
  • 00:03:16
    With our parameters dialog still
  • 00:03:17
    open, we can move it out of the
  • 00:03:19
    way, and test our user parameters by
  • 00:03:21
    changing any one of the expressions.
  • 00:03:24
    For example, I’ll change
  • 00:03:25
    the width to 100mm.
  • 00:03:28
    Notice the box instantly resizes
  • 00:03:30
    based on the new expression.
  • 00:03:32
    Keep in mind that it’s critical
  • 00:03:34
    to fully define your sketches, as
  • 00:03:36
    discussed earlier in this course.
  • 00:03:38
    Fully defined sketches, combined
  • 00:03:39
    with User Parameters can provide you
  • 00:03:41
    with an efficient and convenient way
  • 00:03:43
    to change your models' dimensions.
  • 00:03:46
    Take a minute to test out
  • 00:03:47
    some different dimensions.
  • 00:03:48
    It’s best practice to test
  • 00:03:50
    your user parameters to ensure
  • 00:03:51
    everything is working as expected.
  • 00:03:54
    This makes it easier to fix any issues
  • 00:03:56
    before your design becomes more complex.
  • 00:04:02
    I’ll set the width back to 50mm
  • 00:04:04
    and the height back to 40mm.
  • 00:04:07
    Let’s now create the Box Top by
  • 00:04:09
    copy and pasting the component.
  • 00:04:11
    Remember our Component groups the relevant
  • 00:04:13
    sketches, bodies, and other assets.
  • 00:04:16
    This makes it easy to create
  • 00:04:17
    duplicates of the same part.
  • 00:04:19
    Start by right-clicking on
  • 00:04:20
    the component in the Browser.
  • 00:04:23
    Select “Copy” from the right-click menu.
  • 00:04:27
    We’ll then right-click on the
  • 00:04:28
    top-level component, which is
  • 00:04:30
    also called the “Root” component.
  • 00:04:32
    This will make sure our pasted
  • 00:04:33
    component is nested on the
  • 00:04:34
    same level as our existing one.
  • 00:04:38
    Notice we have the option
  • 00:04:39
    to Paste and Paste New.
  • 00:04:40
    Paste will create an exact copy that will
  • 00:04:43
    always remain the same as the original.
  • 00:04:45
    “Paste New” will create a copy,
  • 00:04:47
    but will allow us to make changes
  • 00:04:48
    without affecting the original.
  • 00:04:51
    Let’s use “Paste New” In case we
  • 00:04:53
    want the Box Top to be unique.
  • 00:04:56
    Once pasted, we can choose
  • 00:04:57
    to define the location.
  • 00:04:59
    However, we’re going to use the Joint
  • 00:05:01
    command to place this, so let’s click OK.
  • 00:05:05
    Before we move the Top Box into
  • 00:05:06
    position, let’s go ahead and rename
  • 00:05:09
    the component in the Browser.
  • 00:05:12
    Once complete, we can activate
  • 00:05:14
    the Joint command in the Toolbar.
  • 00:05:16
    The “Joint” tool lets you position
  • 00:05:18
    components relative to one another, then
  • 00:05:20
    define the relative motion between them.
  • 00:05:23
    We’ll want to hide the Bottom
  • 00:05:24
    Box in the Browser so we
  • 00:05:26
    don’t select that by accident.
  • 00:05:29
    To use the Joint command, we need to first
  • 00:05:31
    set the “Joint origin.” Defining the Joint
  • 00:05:33
    Origin” for each part is how we position
  • 00:05:36
    the parts relative to one another.
  • 00:05:38
    Generally, it’s best practice to select
  • 00:05:40
    a corner or an item that will not change.
  • 00:05:43
    Let’s select any one of the four
  • 00:05:45
    corners, making sure to select
  • 00:05:47
    on the top planar surface.
  • 00:05:50
    Once selected, we can turn the other
  • 00:05:52
    component back on in the Browser.
  • 00:05:55
    We’ll now want to select the
  • 00:05:56
    opposite corner so our lid is
  • 00:05:58
    flipped to the correct position.
  • 00:05:59
    To make it easier to snap to points
  • 00:06:01
    on a face, place the pointer over a
  • 00:06:03
    face, then hold the Control key on
  • 00:06:05
    Windows or the Command key on Mac.
  • 00:06:10
    Once the second corner is selected,
  • 00:06:12
    you’ll see our Box Top moves into place.
  • 00:06:14
    However, the rotation may not
  • 00:06:16
    be aligned depending on how
  • 00:06:17
    the Joint origin was applied.
  • 00:06:20
    You can fix this by adjusting
  • 00:06:21
    the rotation slider in the Canvas
  • 00:06:23
    or the angle in the dialog.
  • 00:06:27
    Once again, we should test our
  • 00:06:28
    user parameters to ensure the
  • 00:06:30
    Joint was applied correctly.
  • 00:06:45
    Everything looks correct!
  • 00:06:47

  • 00:06:47
    I’ll see you on Day #20 we’re we’ll
  • 00:06:49
    add 3D printable hinges to our box.
