183 SolidWorks Mold Tools Tutorial: Shut off surfaces Video Lecture | SolidWorks: Essential Training (All Commands included) - IT & Software

welcome to tutorial number 183 in this
tutorial we will talk about the shut off
surfaces the next feature in the mode
tool section in this tutorial we'll talk
about what the shut off surfaces and why
we need them and we will see how to
insert them and have a look at the
selection manager options and surface
types look at the cases when we need to
ensure the shut off surfaces manually
and then have a look at the mold folders
so simply the check off surfaces are
shutting the holes in the products for
example we have holes representing the
buttons and the speaker holes so closing
these holes are the shut off surfaces
but why we need to add the shut off
surfaces as you remember from the
previous story we inserted the parting
line for this mobile cover which
represent the lines between the
concavity the mold part but if you again
edit the parting line feature you would
notice a message over there the parting
line is complete but the mold cannot be
separated so the reason why we need to
add a shadow' surface is more parting or
parting surfaces for two separate
between the border of the mold parts the
core and cavity so you will know words
what which part will do the cavity and
which part will do the cool so let's see
how it works here is the set of surfaces
if you click on set of surfaces it will
automatically shuts the holes over there
because they are simple holes and if you
notice the shut off surfaces they are
not shown if you go down in the
selection manager
click show preview so you'll see a
preview for the shot all now we are
shutting these holes so you can imagine
we part to the right of the surface is
in the part of the core the holes or to
the left are in the cavity part so the
cavity will be responsible for creating
this holes for an otherwise and that
will see when we creating this small and
here you have it jeans inches which are
selected you can change which part will
do which for example we can clear
selection and select the inches over
here so you'll notice the sides to the
left of the surface are in the part of
the cone
in other word we can call them parting
surfaces but we still have the rest of
the whole need to be selected in order
to the mall to recognize the part of the
core and cavity and here you have dick
need option in case if there are many
surfaces so you will decrease the number
for surfaces so I will close the shut
off surfaces and I will suppress the
fillet option and the mobile cover plate
5 and to make it easier for selection
and you can still have flipped and
selecting manually here will click on
the parting line again you will notice
the part the shell of surfaces selected
all the holes and now if you go down
over there we can show preview and meet
surfaces and here are the types of the
surfaces so in this side if you notice
this face is straight so it can be
enough to have the contact portion but
in case there are some curves and you
need the surface to match this curve you
can change the type into tangent you can
click on be went over there and change
it to tangent
and here we have also type over there
you have no fill and you have all
contact and tangent kept you click on
the all tangent will convert all the
times to be tangent and if you click on
the wall contact will convert all the
time into contact and here we can show
call-outs or hide them to make it easier
to see so now I will keep the default
selection when I am done
knightly ok so now we have the child of
surfaces are there so you can see a
better you can imagine the shape of the
mould for decor the shape of the cavity
but in some cases maybe this mobile
cover might be simple out straight faces
but in some cases the shot of surface
can be difficult to to make or to be
selected by default and we mean in that
case to make them manually and we will
have an example about that later on
indication we create the chatbox surface
manually and how we can use the surface
commands over there to create our set of
surfaces
and now let's check if we succeed to
create the shut off surface and the
parting line if we go back did the shop
surface here you'll notice we get a
green message the mole can be separated
them through the work and appreciate
between the mold parts the core and the
cavity so a few steps remaining to
create the actual mole lasting for the
surface which we created they are only
surfaces and they are not affecting the
solid body and they are just borders if
we have if you need to have a look at
these surfaces you can find them under
the mold folders expanded over there and
here you have the cavity surfaces and
the surface bodies and the parting
bodies so here you can see the core
surfaces which are in red you can see
them and this are the core side of the
surfaces and here are the gravity side
of the surfaces so the cavity represent
green color and the core surface the red
color and they are equal ND number
you
