Q & A

What is the main focus of the video?

The main focus of the video is to demonstrate how to create complex hole features in Autodesk Fusion 360, which is one of the exam objectives for the Autodesk Certified User (ACU) exam.

What is the first step in creating a complex hole feature in Fusion 360?

The first step is to create a new sketch on the front work plane and draw a rectangle that is 6 inches wide by 2 inches tall. This rectangle is then extruded to a depth of 1 inch to create a basic block.

How can you place a point on the block to start creating a hole?

You can create a point by going to the 'Create' menu, selecting 'Point,' and then using the horizontal and vertical constraints to position the point at a specific location on the top face of the block.

What are some of the options available when creating a simple hole in Fusion 360?

When creating a simple hole, you can adjust settings such as the depth, diameter, type (simple, counter bore, countersink), and drill point angle. You can also choose placement options like 'at a point' or 'from a sketch with multiple points.'

How do you create a counter bore hole in Fusion 360?

To create a counter bore hole, you select the hole type as 'Counter Bore' in the hole command menu. You can adjust settings like the diameter and depth of the counter bore and choose to make the hole go all the way through the material.

What is the difference between a simple hole and a countersink hole?

A simple hole is a basic drilled hole with no special features. A countersink hole has a conical recessed area at the top, designed for flathead screws or bolts, and can be threaded.

How can you create multiple holes at once in Fusion 360?

You can create multiple holes by placing several points in a sketch, then selecting the 'Hole' command and clicking on the desired points. Each point can be used to define a different hole with specific settings.

What types of threads can you add to holes in Fusion 360?

Fusion 360 allows you to add different thread types, such as simple, tapped, and tapered tapped. You can also define threading options like full thread and select from various sizes and classifications (e.g., coarse, fine).

What is the purpose of the section analysis tool in the context of creating holes?

The section analysis tool allows you to view a cross-section of the model to see the internal features of the holes, such as threading, depth, and other characteristics. It helps verify that the hole has been created correctly.

How can you edit a hole feature after it has been created?

To edit a hole feature, you can right-click on the hole in the model history tree and select 'Edit Feature.' This allows you to make changes to any specifications, such as diameter, depth, or type of hole.

Keywords

💡Fusion 360

Fusion 360 is a cloud-based 3D CAD, CAM, and CAE tool for product design and manufacturing. In the video, it serves as the platform where the presenter demonstrates how to create complex hole features for the Autodesk Certified User exam. The presenter uses it to sketch, extrude, and manipulate the design of a block for modeling purposes.

💡Complex hole features

Complex hole features refer to advanced hole types like counterbore, countersink, and tapped holes, which are more intricate than simple holes. The video walks through several ways to create these features in Fusion 360, including the use of the 'hole' command and the application of specific design parameters like depth, diameter, and thread type.

💡Sketch

In CAD design, a sketch is a 2D outline that serves as the basis for creating 3D shapes. In the video, the presenter begins the modeling process by creating a sketch of a rectangle on a work plane, which is then extruded to form a 3D block. Sketches are crucial for accurately defining the placement of hole features.

💡Extrude

Extrusion is a process used in 3D modeling to extend a 2D sketch into a 3D shape. In the video, the presenter extrudes a 6-inch by 2-inch rectangle to a height of 1 inch to create a block. This block serves as the base for demonstrating different hole types and placements.

💡Hole command

The hole command in Fusion 360 allows users to create various types of holes in a model. The video shows how to use this tool to create both simple and complex holes. By selecting a point on the block and applying different parameters like hole type, diameter, and depth, the presenter customizes hole features to fit design specifications.

💡Counterbore

A counterbore is a cylindrical, recessed area at the top of a hole, allowing for screws or bolts to sit flush with or below the surface. The presenter demonstrates how to create a counterbore in the video by modifying the hole's diameter and depth to form the recessed area.

💡Countersink

A countersink is a conical hole expansion that allows a screw or bolt head to sit flush with the surface of a part. In the video, the presenter creates a countersink hole with a tapered angle, explaining how this feature is commonly used for flathead screws and ensuring precise fitment.

💡Tapped hole

A tapped hole has internal threads, allowing screws or bolts to fasten into the material. The presenter uses the tapped hole option in the hole command to show how threads are added to holes in Fusion 360, explaining how this feature provides a secure hold in mechanical designs.

💡Point placement

Point placement refers to the selection of specific locations where hole features will be applied on a 3D model. In the video, the presenter demonstrates how to use the create menu to add points to the top of the block. These points act as reference spots for creating simple or complex holes, ensuring precise alignment and distance between holes.

💡Model history tree

The model history tree is a feature in Fusion 360 that logs all the actions and changes made during the design process. In the video, the presenter mentions how to right-click on previous actions in the model history tree to edit or adjust features like hole sizes and types. This allows for easy modifications and tracking of design changes.

hello everyone we're going to be doing

another spotlighted exam objective for

the fusion 360 autodesk certified user

exam so in this one we're going to be

taking a look at the part modeling

section and we're going to look at this

third exam objective called create

complex whole features

so with that we're going to move into

fusion

and i'm going to go ahead and open up a

new design here

and i'm going to create

a new sketch

based on this front work plane and i'm

gonna just create a block here

this is a very common

uh

very common kind of

model where i'm gonna do a six inch by

two inch tall

rectangle and then i'm gonna go ahead

and extrude this

a distance of one inch

so this is a very common way

that i used in order to show how to

create holes

and i'm going to show you a couple

different ways on creating complex hole

features one is going to be i'm going to

create a sketch

i'm going to click on the top of the the

block that i've created

i'm gonna go to the create menu and i'm

gonna choose point

and along with the point i'm gonna go

ahead and base it off of the

middle or if you go through and utilize

the horizontal vertical if i hold my

shift key

i can find the midpoint and you'll see

it'll be marked with an x so i click and

then i'll click the point there and it

will establish a horizontal constraint

between those two

then i'll probably have to dimension so

from the left edge here

we're going to do a one inch spacing so

we're gonna so we have the one inch

spacing here

i'm going to finish the sketch

and then i'm going to go ahead and under

the create menu i'm going to choose the

whole command so

when i click that

it then gives me an option i can go

placement at a point or from a sketch

with multiple points or multiple holes

so i could do multiple holes and it's

obviously one option that we have but

i'm just going to go over here and i'm

going to select the point

and it's going to give me the option now

you're going to see the hole being

created now i can use the grips

to kind of make the whole different

sizes

and be able to go through and set some

different things i like the depth and

everything so this is a very this would

be a simple hole just kind of drilled

through

and here i can have the shape settings

either i can have it by distance

to an object or all the way through the

material and i could flip the direction

which is not going to do any good in

this scenario so i'm going to make sure

that it flips down you'll see an error

pops up because there's nothing there to

put a hole in so with the hole type i've

got simple i've got counter bore and

i've got countersink i'm just going to

do a simple hole right now and then here

you got the whole tap type is a simple

you can do a clearance hole tapped hole

or a tapered or a taper tapped hole and

then the drill point can be flat or it

can have an angle so

since we're going to be going through

and then down here we can set some of

our different distances so like here we

made that two inches

that block was two inches deep so we can

set the depth of this to be two inches

the angle is usually 118 is pretty

common default number and then the

the diameter of the hole we have at 0.6

we'll go 0.5

and then you're able to see like down

here objects to cut and it says body 1

which is this block so that's looking

good for us

so what i'm gonna do is i'm gonna say

okay

so there we have one hole

that's applied into the part now that's

a simple hole they want us to show you

how to do complex holes so i'm gonna go

ahead and do another operation i could

go through and do the point with the

sketch or i can choose the whole command

i can click on the top face of where i

want the hole to be

but here's the only thing that changes

in this menu is now over here i've got

references so i need to hit i need to

select the word

select in the dialog and then i go over

here and i'm going to select click on

the edge

and i'm going to be able to put that

well i want this to be two inches away

and then while this is open i don't want

to hit enter i just want to type in the

number and then i just want to click on

this front edge and i want that to be

0.5 so that way it's centered in for me

there

so those are those references are set my

distances i'm going to go with a counter

board hole so the counter bore is going

to go with that that's another hole type

and i'm going to stay with a simple hole

that's pretty common so here's the

counter board i can see that i've got

some grips over here i usually like to

use the menus because i think i feel

like it's a little bit more accurate so

but i do want to go all the way through

so i'm just going to go ahead and say

distance all so you're going to see when

you do that

the depth of the hole is set to all

the counter bore diameter is 0.55 we're

going to go 0.5

the depth of it they got us 0.05 we'll

do 0.25

so we'll see where that's at again we

might get a little bit of an error here

and then because the depth or the

diameter down here and we'll go ahead

and set this as 0.25

as well so there you can kind of see a

preview the area in red is kind of what

we're committing to

as we go along and then i'm just going

to go ahead and say okay

here is our counter board hole

so with the cylindrical recessed area

here at the top and then the through

portion right here that goes all the way

so next hole type

again we can go through and i'm gonna go

ahead and go to create i'm gonna show

you with multiples so i'm going to do

we're going to create a new sketch i'm

going to click the top of it i'm going

to go ahead and set a point in i'm going

to grab a couple of points here

and let me throw three on there see if

we can get

get three points going so

here as i go forward i'm going to

let's distance from the back edge here

0.5

from

from the center of the last hole to this

one

we'll set at 1.5 we'll say

from this hole to this hole we'll go

one inch and then from this hole or this

point to this point

we'll go one inch as well we'll see how

this works and then in order for these

to be fully constrained i can choose the

horizontal vertical i'll choose this

point and choose this one

choose this one and choose this one and

this ensures that all of them are going

to be fully constrained and they turn

black to show that they are fully

constrained i'm gonna say finish the

sketch

now when i choose the whole command

you can always click and select

multiples if you wish like if they're

the same hole type but if i don't i'm

going to hold the shift key and i'm

going to click those options again which

deselects so i'm going to go ahead and

choose this i'm going to change this

over to a countersink hole

and we're going to go ahead and make

this countersink let's do a tapped hole

which is means the portion you see the

lines that show up in in there as well

so we're going to go a full thread and

then let's do a flat drill point

and here we'll go the depth is going to

be instead of 2 inches

we'll set this to 1.5

we'll set the diameter set of

0.275 we'll say 0.5

82 degree taper angle

and then the depth

or excuse me the diameter of this is

going to be defined by what size that we

have so they've got 0.25

we could probably bump this up to

3

8.375 three eighths dash sixteen unc

that the threads it gives us the

threading designation so we just go

through and need to pick so let's say

38-16 coarse thread works pretty well

and whether it's a one b two 2b or 3b so

that's the classification so we

definitely know it's a it's a an

internal type so that's a b class so

most general is we could probably do b

right hand turn and we can choose to

whether it's modeled

or not so i'm going to check that and

i'm going to say okay so then you can

see there's your counter bore

so it has the conical recessed area and

then it has our threads in there and we

can see this one is a flat bottom type

so the other way we can check that is if

we choose the section analysis tool i

can choose the face of the block

drag in about halfway negative 0.5 and i

can type that in as well and i can say

ok and i can see what kind of what kind

of hole that i have created there

so

all right and then here in the section

analysis if i want to turn that off i

can always either

delete or i can hide the section

analysis sometimes if i know i'm going

to use it multiple times

to check on things i can just go through

and hide it by clicking the toggle

visibility off

so if i want to now i have two whole or

two points that i didn't use from last

time so i'm going to choose those i'm

going to go ahead and turn the sketch

back on that brings back my points

choose my whole command for this sake

i'm going to click both of these these

are both going to be the same hole i'm

going to do a simple hole it will be

threaded and we're going to go ahead and

down here so you can see here's the

depth uh we're going to go ahead and

have this be

through all the way through

and for the size you'll notice the

diameter i don't have the option to

check so i'm going to choose from the

size we're going to do

0.25 we're going to do a 1 4 20 unc

so 1b right handed we're going to model

the threads and we're going to say okay

so both of these holes are going to be

the same

and i'm going to go ahead and toggle the

visibility off of the sketch

and if i take a look there's my holes

modeled all the way through

if i go ahead and open up my analysis

folder and turn it on i can see

what kind of options that i have there

so

all right so this is a review

of kind of creating complex hole

features and as you create them you can

keep in mind you can always go back down

here to the model history tree right

click and choose edit feature to make

any changes if you need to make any uh

specification changes to any of your

whole sizes and types but otherwise this

video concludes on how to create those

complex hole features

and good luck with

preparing for your acu exam if you have
