4:07
CAD from uh 02
4:10
expert and now we will come back to our
4:14
tutorial
4:16
now I will uh create a new file and uh
4:20
let's insert our body and uh on the
4:24
origin plane and uh select this top
4:27
plane and uh click on the
4:30
sketch and let's hide the origin plane
4:35
now I will select a twopoint rectangle
4:38
and uh create a
4:41
rectangle and uh let's make it uh
4:44
symmetric select this point and uh this
4:48
point and uh select the center one and
4:52
uh let's give the horizontal
4:55
dimension 500 mm and give the vertical
5:00
dimension 500 mm now it is in a square
5:05
and uh we will come out of the
5:09
sketch and now we will uh extrude it
5:14
we will uh extrude it to the distance of
5:16
300 mm so click on the pad and uh
5:20
provide the value 300 mm and say
5:24
okay now here we will create a round
5:27
profile and extrude it select the face
5:30
and uh click on the
5:33
sketch and here we see that uh this is
5:37
not symmetric so let's make it symmetric
5:40
we will go to the model edit this pad
5:44
and we will make it symmetric the reason
5:48
behind it when we edit our sketch again
5:50
we will get our center here and now I
5:53
will create a
5:55
circle so here I am creating this circle
5:59
on this face and let's give the
6:04
dimension let's give the
6:07
200 and click on okay and now we will
6:11
select the sketch and uh extrude it to
6:15
the distance of
6:18
150 or uh let's make it uh
6:24
200 so here we have made this pad 200
6:28
and now let's uh consider that you have
6:32
made a mistake
6:35
you want to create this uh
6:38
round feature on a back side of a face
6:42
but by mistake you have created this on
6:45
the front face
6:47
so you might select it and delete it and
6:53
again select the face and create a
6:55
sketch and the constraining and then
6:57
extrude it in Frecad if we have did some
7:01
mistake we have selected the wrong face
7:05
then we can redefine it to the other
7:09
face so let's see how we can do it so
7:13
expand the sketch select the sketch and
7:17
right click it and you will see the
7:19
attachment editor so on attachment
7:22
editor you will see here pad f face
7:25
phase 2 which means that uh this face is
7:30
identifies as a face 2 this might be
7:32
three four or like that so this is the
7:35
internal numbering system how fread
7:38
rename it now we wanted to define our
7:42
feature on a back side of a face so we
7:45
will select it and press delete so here
7:49
no reference selected and now click on
7:51
the reference one and we will rotate our
7:55
model and select this back face so you
7:59
can see the message here attached with
8:03
mode plane face and it is in a green
8:05
color which means it is accepted and
8:09
click on okay
8:13
now still our this round profile on the
8:16
existing
8:18
face but here we are seeing the rebuild
8:21
symbol so we will right click our sketch
8:24
and recomp compute
8:26
it so our sketch is got recomputed but
8:30
our pad feature still need a rebuild so
8:35
we will select the pad and we will click
8:38
on recomputee object so you can see that
8:41
uh it successfully transform on the
8:44
other side without deleting the sketch
8:47
or pad let's do some more experiment
8:51
let's define the sketch on this face so
8:55
we will do the same thing we will select
8:57
the attachment
8:59
editor this is the face four we will
9:02
delete it and we will click on here
9:05
select reference and select this face
9:08
and say
9:11
okay now we can uh rebuild from here or
9:16
you can select it and go to the edit
9:19
options and you can refresh it so you
9:23
can see that it got refreshed and at a
9:26
single command it updated my sketch and
9:28
pad and let's redefine it on the other
9:31
side so we will go select attachment
9:34
editor delete phase three and select
9:38
this
9:39
face select reference and select this
9:42
phase and say okay and now here we will
9:46
go to the edit and uh refresh shortcut
9:49
is also given F5 once you refresh it it
9:53
will be get
9:54
updated now we can also define it on the
9:57
top face we will select go to the
10:00
attachment
10:01
editor delete it select reference and
10:04
select this top face say
10:07
okay and press F5 from the keyboard so
10:11
it got redefined on the top face so this
10:15
is how we have redefined this uh our
10:19
sketch as well as pad to the multiple
10:22
faces so if you have a did the sketch on
10:27
a wrong face so never delete that sketch
10:30
always try to redefine it until and
10:33
unless your sketch is giving lots of
10:36
problem then delete your sketch and
10:38
create a fresh sketch but for a simple
10:43
type of error like if you have created
10:45
some pad then redefine it with the
10:48
attachment
10:51
editor and save your time so this is all
10:54
about this tutorial how to redefine
10:57
sketch to the new reference in freead
11:00
1.0 so this is all about this tutorial
