🎥 Introduction to the Video and Overview of the Component

In this video tutorial, the host welcomes viewers to the channel and introduces the topic: creating a component by following a provided drawing. This is exercise video number six, and a download link for the drawing is available in the description. The host explains the views provided (front, bottom, and isometric) and outlines the steps to create the component, starting with the front view, followed by extrusions, and adding necessary radii at the end.

05:01

🛠️ Creating the Front View and Basic Shapes

The host begins by creating the front view on the front plane. They draw construction lines and circles based on the specified dimensions (24mm and 50mm diameters). Tangent lines are added to connect the circles, and unnecessary lines are trimmed. The inner profile is created by calculating and drawing arcs and offset lines. The process involves using the sketching tools to ensure accurate dimensions and relationships between elements.

10:02

🔄 Mirroring and Refining the Inner Profile

The video continues with the host refining the inner profile by adding radii and mirroring lines. The host explains how to calculate and draw the arcs based on given distances and dimensions. They use the trim tool to clean up the sketch and ensure all elements are properly constrained. The profile is mirrored to ensure symmetry, and final adjustments are made to prepare for the next steps.

15:04

🔧 Completing the Sketch and Extruding the Component

With the sketch complete, the host moves on to extruding the component. They explain how to calculate the extrusion distance (60mm) to ensure the mid-plane remains centered. The extrusion is performed symmetrically. The host then offsets the top plane to work on the Y-profile, creates construction lines, and sketches the necessary lines. The profile is mirrored and radii are added to finalize the sketch. The component is extruded and additional details, like fillets, are applied.

Keywords

💡Spark Plug

A spark plug is a device that delivers electric current from an ignition system to the combustion chamber of an engine, where it ignites the compressed fuel-air mixture. In the video, the spark plug is the component being designed and discussed, and the tutorial focuses on its detailed creation process.

💡Extrusion

Extrusion in the context of the video refers to the process of creating a 3D object by pushing material through a die to give it a specific shape. This is a key step in the tutorial where the front view of the spark plug is extruded to form the main body of the component.

💡Front View

Front view is a term used in drafting and design to describe the appearance of an object as seen from the front. In the script, the front view is the starting point for creating the spark plug, involving the drawing of two circles with specific dimensions to represent the spark plug's profile.

💡Isometric View

An isometric view is a method of representing three-dimensional objects in two dimensions, providing a more comprehensive understanding of the object's shape. In the video, the isometric view is used to illustrate the spark plug's design and to ensure that the radius is correctly applied without unnecessary edges.

💡Radius

Radius in this context refers to the distance from the center of a circle to its edge. The tutorial mentions providing a specific radius manually to avoid unnecessary edges in the 3D model, which is crucial for the spark plug's design accuracy.

💡Construction Line

A construction line is a temporary line used in drafting to help establish the position and size of other objects. In the script, construction lines are drawn to assist in creating the front view and setting up the dimensions for the spark plug's design.

💡Tangent

Tangent in geometry refers to a line that touches a circle at exactly one point. In the video script, tangent lines are used to connect the circles in the front view, ensuring that the lines touch the circles at the correct points without crossing.

💡Offset

Offset in drafting means to create a parallel line or curve at a certain distance from an existing line or curve. The script describes using the offset function to create lines that are parallel and at a specific distance from the outer portion of the spark plug design.

💡Mirror

Mirroring in design is the process of reflecting an object across a line, creating a symmetrical counterpart. The script mentions mirroring lines and profiles to create symmetrical parts of the spark plug, which is essential for its design integrity.

💡Extrude

Extrude in 3D modeling is the action of extending a 2D shape into a 3D form by pushing it along a path or direction. The script describes extruding the top profile of the spark plug to achieve the final 3D component shape.

💡Dimension

Dimension in drafting refers to the numerical values that define the size and position of elements in a design. Throughout the script, various dimensions are given to different parts of the spark plug, such as the radius of the circles and the distances between lines, to ensure the accuracy of the model.

hey guys and welcome back to another

video of the spark plug so in this video

tutorial I am going to show you how to

make this component by looking at the

drawing of it this is going to be over

we exercise video number six you can can

find the link to download this file in

the description below so don't forget to

check it out also let's start without

any time so we what we have here we have

a friend view and a bottom out of you

can call it for Tao view as well so and

here are to isometric view just to make

you guys understand how our component

fully you fly after the total completion

of the drawing so what we are first

going to make this we are going to make

the front view on the front plane we are

going to attach the front view on the

front plane and then we are going to

make some extrude extrusion and then on

the bottom of the or the top plane we

are going to make this top profile and

then we are going to extrude curve to

get the final component and one thing

the radius as shown in guru color is

isometric view is not being shown in the

front order top you to avoid any

unnecessary edges so we are going to

provide this radius manually at the end

when sever 3d is complicated so we will

start by making the front view as you

guys can see it consists of two circles

with a central Daiya our center distance

CD of hundred mm and the Daiya internal

and external Daiya r t and 36 and here

radius is 6 and 12 respectively so just

to go to select sketch and the french

plane and what we will do from origin

draw a construction line switch on the

construction mode and a construction

line like this and just switch it back

off press C for circle and draw for

circle like I am doing here get the

dimension the outer radius was 24 and

the inner

the inner walls 12 similarly here the

outer diameter was 50 the inner was 36

and the outer walls 50 as you guys can

see the outer die as 50 and the inner

statistics the outer radius is 12 so the

die is 24 and the inner die is 12 and

the signe is hundred mm so press e for

dimension select these two point and

give it a dimension of Andra Devon

that's okay now one still just slide it

to this side

you guys can anytime switch of the

dimension if they are too much and are

restricting your view so next step we

are going to make these two tangent line

to join this circle so press L for line

anywhere on the circle and draw this

line and then again go to constrain go

to tangent constraint select all these

to make the tangent relationship will be

desktop here go to mirror select this

line and the mirror line would be the

construction line we have drawn earlier

and this okay press T for trim and draw

and delete these excess line like I have

here so now what we are going to do is

we are going to make this inner profile

so as you guys can see this arc here we

don't have any dimension for this R but

we have a distance from the outer inner

circle is 8 so what we are going to do

we are going to find the radius of this

inner circle so die is 36 the red means

the radius is 15 mm so from this center

to the outer edge this is 18 18 plus 8

is 26 that means the radius of this arc

is 26 so let's see and from this circle

draw any circle press T for dimension

select this and to give it radius right

click and say

radius and radius is 26 and resti

delete the outer portion now we are

going to make this line and this line as

it is can see this line is offset from

the outer portion by 8mm so press offset

you guys can find offset in the modify

menu select this line and don't forget

to and check the chain selection because

we are only going to offset this

particular line and off position would

be 8mm again mirror this line with

respect to the center line and press ok

now press trim to delete these excess

line yeah like like here and press now

we are going to give this radius R of 5

so fill it just undo and click on fill

it 5 radius and repeat this step for

here as well and press ok now what we

are going to do is we are going to make

them in a portion also so we don't have

the radius of this circle so we have the

distance from the inner circle as 8 so

for that draw a circle of any dimension

like I am doing here and press L from

this point draw a vertical line and from

this point draw a vertical line and

press D and give it a dimension of 8mm

now let's see for circle and draw a

circle till we get stained gent to this

line and this ok now you can just delete

the inner circle these two vertical

lines and press T for trim and delete

these lines now we have here our

dimension is completed so once completed

just click on finish

sketch and go to isometric view now what

we are going to do is we are going to

extrude it and the extrusion extrude

distance can be calculated from the

thickness of this component as it is

kisi the maximum thickness from the

front and top view is 60 mm so we are

going to extrude it symmetrically that

30 30 mm each so that our mid Plains

remains in the mid portion of the

component so extra distance would be 60

click on extrude select this spline the

direction would be limit prick and you

can just select the measurement as whole

length and the distance would be 60 and

you component press okay now again bring

back the sketch so what we are going to

do we are going to work on top plane but

if if I work on this plane then I will

not be able to select our line cause our

body will be intersecting with the

sketch plane so what we are going to do

is we are going to offset this plane so

that it gets above our solid body and

press ok now again go to create a sketch

click on this plane this will work as a

top plane and press alpha line and from

origin draw a construction line like I

am doing here now we are going to make

this Y profile we are only going to make

the upper one then we are going to

mirror it according to the our

construction line we have just created

so we have one line to line and three

line and then we have an offset profile

of 8mm the radius would be will will

give that in the later part of the video

so for now press L and draw this will

get the construction mode and draw line

like this

now pristine this is going to be 0 mm

now so just make this line coincident to

this point or you guys can equal or you

guys can see the dimension from this

point is given the 23 or you guys can

just put it coincidence so the first

line that the thickness at this point is

14 so 14 divided by 2 is 7 so that means

the distance from this line to this line

is 7 mm and press ok and now as you guys

can see now the distance the distance

from the center of this circle to the

first the first turning the first

turning point is 25 and the second

turning point is 75 so just press D and

the center was me we have created our

circle from the origin so this point and

this point is 35 and this point and this

point is 75 like this now what we are

going to do is we are going to make this

point equal to this point so for that

just press D and and give it a dimension

of 25 why I gave 25 is that it will

adjust closely that this is actually the

center of the outer circle so the radius

of the outer circle was 25 so that the

radius is that means the radius is 25 so

the outer ball Daiya was 52 the radius

was 25 reduced event so from this point

to this point radius is the distance 25

that means I took that why I took the

dimension as 25 now similarly repeat the

step for this point also

this point so this time the outer radius

is 12 so from the centerline I think

this one is the centerline no this is

not the centerline you guys if you if

you are not able to us swipe the center

point what what what you have to do is

just click on P for project you guys can

find that option like here and go just

move it slightly and just click on this

circle and press ok

so what it will do it will this project

this circle on your working plane again

go to look at normal to now on we are we

we have the line representing the Daiya

of a circle now again press L and from

the midpoint of this project red line

the this triangle represent that you are

on a midpoint of this line draw a line a

vertical line let's just meet it

construction now this is the center of

the this circle so from this circle

press T this point and make it 12

it is a secondly it's now perfectly

coincidence through the last part so now

we are going to make the the make this

profile so this is 8 mm and this get X

offset by an 8 mm throughout the profile

so what we are going to do is we are

going to press L go downwards press 8

and press ENTER the switcher of the

construction line between the switch of

the construction line

now it's a regular one and press L and

just go like this and join here now what

you have to do is we need to make these

these two line parallel so go to

constraint click on parallel parallel

constraint select this line and this

line make this parallel make them

parallel and press D for dimension give

it a dimension of it

similarly we already have the eighth

dimension here also so now the only

thing left is to mirror this profile

again go to mirror command let me just

press L and join this line also now go

to mirror select the all the line that

is needed to be mirrored select this

line this one is this one this one this

one and this and the mirror line would

be this and this okay now we have a

closed sketch now only thing left is to

provide these radius so already as you

guys can see the outer radius is 20 and

the inner one is 10 similarly the 20 is

here so what that just go to fill it

give it a radius of 20 repeat the step 4

here as well

this is also 20

this is also 20 and the inner would be

will be 10 and this side also will be 10

and again for the last time select this

line and this line in the radius 10 and

press ok so just cross-check all the

line that you have given the proper

radius to 20 20 10 and 10 just look at

one way now if what is just this grey

area represent that my body is closed

click on finish the stage so this is how

it will look like so what we are going

to just go back to the sketch by

right-clicking and I rate the sketch

press to point rectangle and draw a

rectangle from the outer and press

finish the sketch now what we are going

to do is we are going to extrude and the

outer portion not that inner one and we

are going to just extrude cut it and

press ok and now we have our body nearly

99% complete code so only thing is left

is to make the radius R 2 so for that

just go to press f4 fill it select this

edge this one select all the edges that

are visible to you and press do and ok

now we have given the radius press shift

and to switch the color toggle you don't

want it or you can just press a for of

your ends and give any appearance that

you want your part to be so let me just

go to

metal ammonium and okay if I just select

the radius

so this is how our component will look

like after complete nation to completion

so hope you guys will enjoy the video

okay one edge got left

so again just select this let me just

select off let this edge and they said

there's two and perfect no yeah complete

it so hope you guys will enjoy the video
