from this tutorial we will start new

training series

for solidworks 2020. if you want to see

more such type of videos then please

subscribe to my channel

and press the bell icon let's start

when you start solidworks many of you

may be seeing this welcome window

you can start working in part

environment

by clicking on this part button here and

if you don't have this welcome window

then

you will have to click here on new

button

it will show this window if you have

selected advance

and if you have selected this then it

will show this window

so in this window you can start part by

clicking here

and by clicking on ok

and if you have this advanced window

select this part and click on ok

so it will start part environment now

in this tutorial at first we will learn

some basic

sketch commands to switch to sketch

environment

click here on sketch and click here

on this sketch button as we are only

going to create

some 2d sketches therefore you can

any plane suppose i will select this top

plane now here

i have selected this mmgs unit

by clicking on this you can choose your

desire unit

so they have provided mks cgs

ips and mmgs so i will be working with

mmgs units so this mmgs

have millimeter gram and second click

outside

first command we will learn line here is

the line command

keyboard shortcut is l click on line

then you will have to specify first

point

always ensure that when starting a new

sketch

always use this origin so that your

sketch will be fully defined

and properly constrained click first

point here

take your cursor away now here in this

yellow box

you can see that there is horizontal

line

this yellow box with some symbol is

called as

relations so it indicates horizontal

that means the line you are going to

create will be horizontal

and here also you can see that angle

indicated is 180 degree

click to stop line command press escape

so here this horizontal line is created

and this horizontal relation has been

applied to it

to give dimension to this line click

here on smart dimension

click on this line take your cursor

below

and click specify length of line suppose

i want

line of 80 distance type there 80

and press enter and to stop dimension

command

press escape so here this line of 80

distance is

created click on line

take your cursor to this end point these

two circle indicates

it is catching endpoint click and take

your cursor above

so here now it is showing yellow box

with vertical line

that means your line is straight and is

vertical

click then by clicking points

you can create your shape as per your

requirement

and as you take your cursor here you can

see that

it is automatically tracking from the

origin click there

and click once your shape got close

and

it has filled with blue color the

meaning of this filling is that

this shape is perfectly close and is

suitable for

3d creation and if you don't want to see

this filling

then you can turn it off by clicking on

this shaded sketched contours

so it will remove those filling but i

will recommend you

to keep this filling because it will be

very useful

when creating 3d objects

to stop line command press escape

here also you can observe there are two

colors for

line object one is in blue color and one

black color the object which are with

for which location is defined with

respect to this

origin and suppose if you want to

convert this horizontal line into black

color

you will have to define location of that

line the location of this line will be

the length of this line

so click on smart dimension

click on this line take your cursor on

this side and click

then specify length and press enter

so here you can see that this line is

also converted to black color

right now this sketch is under defined

the meaning of under defined

is you still will have to give

parameters and dimensions to completely

define this sketch

suppose we will also give length of this

line 25

enter then press escape then suppose i

want this line

collinear with this line so to

add relations select this line

press ctrl and select this line

so here list of relations has been shown

from here you can add this make

so they will become collinear and this

symbol of collinear is added

which shows that these two lines are

collinear

click outside and these two lines has

become black

because they are properly defined

again smart dimension suppose i want to

give length of this line

as 25 enter

then length of this line again as 25

enter click outside now if you see that

complete sketch got black color and it

has been said here that

it is fully defined now if you try to

give dimension

then it will be over defined suppose if

i try to give length of this line

and click here it will give error

that make dimension driven and your

sketch got

over defined because this dimension is

not necessary

as we have already specified this total

length

that means

this length can be easily work out or

there is no need to specify this length

because this length is already included

in this length

so this problem can be solved in two

ways you can make this dimension as a

driven

or you can leave this dimension as

driving

if you need this dimension as a

reference dimension

then you can make this dimension as a

driven

click on ok and click outside

so here this driven dimension is shown

in gray color

and all the other dimension are shown in

black color

the meaning of this driven dimension is

that if i

change any dimension in this line this

will get

changed suppose if i change

this dimension to change dimension

you will have to double click on that

dimension so here

dialog box will appear here you will

have to specify

change dimension suppose i want it 20

enter so here you can see that it

automatically got 35

and the black dimension remain as it is

so that is the meaning of driven

dimension so it will get

changed automatically without giving any

indication to you

then press escape to stop dimension

command

then suppose i want to make this

dimension as a driven dimension

for that click on this dimension line of

right click and here you will have to

click on this driven

and press escape so here you can see

that this dimension has become driven

and suppose i want to convert this

dimension to driving dimension

again click on this line right click

and click on this driven so that it

will

make this dimension driving so

if i now change this dimension to 20

enter so here you can see that now this

dimension got

changed so this is the concept of driven

dimension

so just click and press delete button

so that dimension is removed again click

on smart dimension

again select this line take your cursor

above and click

and if you click on this leave this

dimension driving

and click on ok then your sketch will

become

over defined so once your sketch got

over defined then you have two options

you can either delete one of the not

required dimension

or you can convert one dimension to

driven dimension

suppose i don't want this dimension so

select it and delete it

so here you can see that our sketch is

fully defined

then press escape to remove these

objects

press first mouse button and drag the

mouse and release the mouse

and then press delete button on keyboard

if you want to create some reference

center lines

for that click on this arrow near line

and click on center line

then suppose i want to create one center

line from this point click there

and click here then to stop

center line here double click so it will

stop creating that center line further

ahead

but your centerline command will be

still running so

i can create one more here and again

double click

i need one more here

then double click and escape so here you

can see that

are

attached to this origin but this line is

blue

because we have not given any dimension

so to make it black

we will have to place one dimension

click on smart dimension

select this line select this line take

your cursor below

suppose i want dimension of 100 enter

press escape so here this line also got

black then to pan this drawing you will

have to press ctrl

mouse

to zoom it rotate middle mouse button

towards you

then it will zoom it and if you rotate

middle mouse button towards monitor

then it will zoom minus suppose i will

zoom it

i will rotate middle mouse button

towards me then suppose i want to create

one circle here for that click here on

take your cursor on this origin click

center point here

on origin take your cursor away and

click

then i want to create circle on the

intersection of these two center lines

so take your cursor there here it is

showing intersection

object snap click there

and click press escape

for dimension click on smart dimension

select this circle take your cursor

outside and click

specify diameter of 60 enter

we will just pan it below press ctrl

press middle mouse button and drag the

then click on the circle take your

cursor outside

and click specify diameter of 40

enter press escape

and suppose i want to create one tangent

line

here

and click take your cursor on this side

once it shows the tangent symbol click

there

and double click so here tangent

line has been created and suppose if you

want to create

line away you can also create it away

press escape to apply tangent object

snap

select the circle press ctrl select this

line

and from here you can apply tangent

relation

click click outside

select the circle press ctrl and click

on this line

again click on make tangent so here this

line got tangent

properly then suppose if you want to

remove these extra lines

you will have to use trim entities click

on trim entities

easiest method is trim to closest

in this method it will remove the object

on which you clicks

so here you can see that here is a extra

line

that also we can remove to see complete

object

you can directly click on this zoom to

fit or you can also press

f so here this has been trimmed properly

then same way you can remove these

internal objects also

just click on it so those objects will

removed you can also use zoom to area

to zoom a particular area click

then press first mouse button drag the

mouse and release the mouse

press escape and click

again zoom to fit now here you can see

that

still it is not shaded for 3d objects

so there is one more problem here again

zoom to area

press first mouse button drag the mouse

release the mouse

press escape and click

zoom to fit so here it got properly

filled

that means it is properly closed

this power trim is also useful tool

suppose i want to remove these outside

center lines

then click on this power trim to use

power trim you will have to press first

mouse button

and drag the mouse so whichever object

is crossed

by this gray line those objects will be

trimmed

so that is power trim then corner

for corner we can create some objects

suppose i will create some lines so that

it will be easy to explain corner

double click click and escape

then again trim entities then corner

then suppose i want to remove this

portion so in the case of corner you

will have to click on the objects you

want to keep

so it will remove the objects ahead of

that intersection

point just click on the objects you want

keep suppose i want to keep object from

this side

so click on this line so in this way you

can use corner

so it will trim it and it will also

extend suppose if i click on this line

and this line

so it will extend this line and it will

create corner

so in this way you can use corner tool

then trim away inside press escape

i will create some more lines

zoom there pan it escape

then click on trim entities trim away

inside

for this you will have to define

boundary inside which you want to trim

the object

it will automatically trim

object from inside this boundary and you

can also use window selection

press first mouse button and drag the

mouse and release the mouse

it will automatically select those

objects and in this case

it will remove internal objects press

escape

then for undo you can click here on undo

and

ctrl z is shortcut so i will just undo

outside

click then select objects

outside which you want to trim so i will

select these two lines

i will use this window selection click

first mouse button drag the mouse and

release the mouse

so here objects from both the sides has

been removed with reference to

these two lines and we have already seen

this trim to closest

trim to closest can also be used for

removing the

objects zoom to fit

then there are two more options keep

trimmed entities as construction

geometry

so even though you trim it it will keep

it as a reference

line suppose i will just undo it

so i will have those objects

and i will click on trim entities then i

will take here

keep trim entities as construction

geometry

and suppose i will trim this line so

here you can see that

that line has been trimmed but it has

been kept as a reference geometry or

construction geometry

so this geometry will be there for

reference but

it will not be the part of your sketch

for 3d creation

so in this way you can use this trim

entities as construction

geometry then there is ignore trimming

of construction geometry

now these are the construction

geometries if you tick here

and suppose if i use this power trim so

when i will power trim

it will only trim the entities it will

not remove these construction

objects so even though you take your

cursor over it

it will not remove it so this is a very

useful feature

because number of times we want to

remove actually main objects and we

don't want to remove

center lines or reference lines press

escape

one more command we will see that is

mirror entities

we'll just pan it and we will create one

entity here

for mirror

suppose i will create one sketch like

this

press escape for mirror you will have to

create

center line also to define as a mirror

center line click on center line

and i will create one horizontal center

line

double click and one vertical center

line

press escape i want to mirror this

select this entity using windows

selection

click on mirror entities

click here on mirror about

and select the center line and click on

ok so here this mirror has been created

around this center line

again mirror entities select these lines

if you want you can remove the original

object and keep the mirror image

suppose i want this object below on the

opposite side

and i want to remove from here for that

remove this copy option

click here on mirror about and select

this horizontal center line

and click on ok so here it has removed

the original object

and it has kept mirror entity so in this

way you can use mirror entities

then sometimes if you rotate this object

by mistake

you can go back to original view by

clicking here on previous view

zoom to fit so that's all in the next

tutorial

we will solve some exercises based on

this theory lecture

so thanks for watching we will stop here
