let's go ahead and tidy up a couple of loose ends what's up i'm jonathan and
welcome to maker tales where i'm sharing my maker journey to help you go
further in yours so don't forget to subscribe and hit
that little bell icon to never miss an opportunity to keep making
this video is all about showing you a couple of loose ends that i find
very useful within my blender precision workflow i'm going to be keeping this
video as short and to the point as possible as
they're not really that complicated so first one is i did show you the
3d edge loop before when we were creating
this rod here but i just want to show you it within a little bit more detail
so for instance this entire face edge loop around this
cube is an what it says a face edge loop
and so if i go ahead here and i hold down
alt and i click on this side it's going to select
that edge loop there now let me show you this in a little bit more detail by
creating a cube here and this is going to be the point where
it's going to make the most sense so if i move this up up here so
if i wanted to select the edge loop all around
this face here i go alt and click and it does this edge loop here however
if i wanted it to have been the other edge loop i go as close to that edge as
possible and then i do my alt click and that's
how you're able to do different selections of edge loops
really quickly of around an object or faces do keep in
mind that when there are seams like this though
the edge loop will be broken so for instance if i were to select here
you see there is a seam line right here so i'm going to actually have to
physically go shift select those but then i can go ahead here again and go
alt shift and click and then i can carry on doing my
selection so shift click these and then the rest of this edge loop should be
able to finish off by going alt shift and click i'm going along this
direction and this one because there is a seam
right here i have to do it this way but that there
is how to do a edge loop selection
having shown you how to do a loop selection
let me actually show you how to do a loop cut as well
this one is very much within more of an organic modeling workflow but
it can be extremely useful so i'm going to go to the cube here because it's not
going to work so great on this object and i'll explain
why later but what i'm showing you is this here
which is the loop cut or the shortcut is control
r and you'll see because i already had an edge selected it moves here
and then whichever edge i move to it shows you this yellow line
now you can use the scroll wheel to add more edge loops to this i'm going to
leave this with one i'm going to left click
and what i'm going to do now is i'm going to move it all the way to one edge
because this is usually how i use it then i do a
click i already have my cad transforms turned
on so i'm going to go and do a g for moving
i'm going to move from this vertex and i'm going to constrain it
on the y and now we can move this to whatever distance i'm wanting so let's
go 0.25 fantastic now
if i wanted to go ahead and cut this up again
well you can use the knife tool which is the one over here but i
usually prefer using the loop cut because what i'm able to do is do the
loop cut i can then divide my surface up to what
i'm wanting here then i can do a click and
then i can right click to bring it back to where it was snapped
to the zero factor and of course here i can increase the loop cuts
manually later on let's say i actually wanted three
and then i can go ahead and do my face selection
and select these here and extrude those up
just like i showed you in one of the first
videos showing blender though we're going to have all
these leftover edge loops so it's up to you how you want to use this loop cut
i usually leave those till i'm later on in my model and then i go about
i go into my edge selection and then i go ahead and just use my circle select
deselect what i'm not wanting select all the things that i am wanting
i'm not going to select them all now and then hit our x and
i dissolve all the edges that i don't need now the reason why the loop cut
isn't going to work on our object down here is because we
the way that we have our edges set so because we have this edge here
and it isn't actually creating an edge so to speak from one edge to another
edge is creating an almost a triangle shape here the
loop cut won't actually know how to do this loop cut
you will see that there will be sections that it knows where to do the loop cuts
and how to do them but that's the reason why it's because
this here it's not a face to face to just
one face to another face here it's a weird shape that's going on
however what it will work with is things such
as this cube here so we could do a loop cut right here
and that works perfectly fine use our scroll wheel to add
more this then lets us go and do something crazy
like this we can then go into our face selection
use our newly discovered loop selection and select these faces here then we can
go ahead and extrude these out oh making sure that we
are setting this extrusion correctly extrude
via the normals and there we go we can do some crazy
crazy things here but for instance that's an
example where the loop cut was actually very handy
of course if you're going to do this with precision you would go about and
make sure that those first loop cuts that were set
here that you actually had them already set to how you wanted them
so making sure that they were set at the distance that you
wanted from such another edge as you've seen
selection is very important within blender
and there is one very powerful way of doing a selection that i haven't shown
you yet and so i'm going to go and do this with
the face selection and what i'm actually going to
do is i'm going to go out here and i'm going to create a weird shape i
want to create an ico sphere here and let's go into edit mode let's go and
scale this up it doesn't really matter where i'm
scaling this i'm going to scale this three dimensionally
and now this selection method needs the numpad plus and minus so
i'm not 100 sure how you do this on a laptop but i'm pretty sure you
using the emulate numpad the plus and minus up on the top right will work just
fine and the way this works is by using
control plus will increase your selection
and there you have it increasing and control minus
is decreasing now what's really powerful of this is that you can actually do this
on two points and it will select from here so
i use this quite extensively sometimes in my models
because it's a great way of selecting for instance all of one thing
and when you can't see it by just pressing it lots of times
and then you have it there it's as easy as that
so for instance let's say we couldn't see the inside
the rest of this model here well we could go into it
we could select just one face and then hit control
and plus and then we're selecting all the faces press that a couple of times
then we know that we've selected it all and that there is the numpad selection
increasing and decreasing also keep in mind that
this also works with edges and vertices so for instance if i went to this edge
here well increasing just by one edge is
going to select all the other edges so it's a pretty decent way of selecting
so also showing you that in the vertex
selection so if i were to start here and carry on going plus it's going to
select all the vertices that are basically to relation to it
something else that's quite useful is the ability of being able to hide
objects now i have shown you how to hide objects
here in the hierarchy but there's also a shortcut so let's
select an object and then you hit h now if you want to bring that object
back we'll bring back all objects it is alt h now you can also
isolate objects by going shift h and this isolates an object for you to
be able to edit with or you can go alt h and bring it back of
course you can just go ahead select all the objects that you're not
wanting and just hit h lots of times to hide that away
that can be extremely useful when you're trying to for instance
i want to see this rod here well i'm going to go
here make sure that i'm in selection select this
i go h and now i can see what i was wanting to work with
and then i can bring it all back with alt h and there it is
now you can also hide collections with control h so right this minute it
lets me hide collections so this goes back to
the organization video where we're able to create collections
and here's another use case for it because if we go here
and we say actually we're wanting to hide all of this
this would then leave us to the hide collection of the collection one
and for some reason it's not hiding it i think it might be because we
don't have any other collections in place let's just add another collection
put that into collection two alt h hide collection
side collection two so you've got to make sure you have two collections and
then we can go alt h and show collection one and that's
a way of being able to basically organize your
workflow very easily lastly it's one more add-on
and this add-on is one that i probably should have shown earlier on
but well we're here now so let's go ahead and let's
enable it you're going to edit preferences add-ons and what we're
looking for here is tiny cad mesh tools
so enable this one it comes with blender and more than anything it just adds some
functionality to some very commonly used things
so let's go ahead and let's just go get our 3d cursor here
let's create a single vertex let's extrude this vertex this way
and now let's go put this one here and extrude a single vertex once again
this way here and here's what's powerful of tinycad
it's one of the most powerful features i find is by selecting all of this
and you right click it and there you'll have it tinycard
is this v to x auto and this does intersection points
super quickly for you it's probably one of the quickest ways of doing
intersection points because you just select it all up and that's it
now go ahead to the documentation down in the description because there's
a whole bunch more other simple things that this does
beautifully that when it comes to it it really is
the fastest way of doing some of the operations
with these loose ends now wrapped up you have a solid foundation of precision
modeling and blender next up i'm going to show you how to put
this into practice i'm going to give you some challenges
and some examples of some real practical use cases right away and then
we're going to talk about the future of what
this series has for you a huge thank you to my patrons
honestly it means the world to me and if usually enjoyed this series and you
think i'm worthy of your support i would love to see you there too
thanks for watching keep making and let the quest continue
