measuring things up and cleaning up our vertexes what's up I'm Jonathan and
welcome to maker tales where I'm showing 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 in this video we're gonna clean
up vertexes because right this minute you would have no idea if there was two
versus over and on top of each other secondly I want to show you a way of how
you can measure the distances that you've already placed down as currently
the only way is for you to manually count the little boxes that you
currently have from there we will then go on to creating a hole in our surface
but I think we should really tackle this problem right this minute before we go
any further in our 2d design in blender precision modeling starting off right
where we left off we have this here I really do hope you went and did the
challenge and this is your floor plan of your house now I want to show you how a
vertex can go completely undetected so I'm gonna go back into our top view
which by now you should know is number seven or by hitting the Z and I'm gonna
select this face so with number three pressed in face select inside of edit
mode I'm gonna hit X to delete this face I won't be saying these instructions
much to know but just to make sure you're aware of them and then if I hit
number one I will go into vertex select so information on the screen is
displayed down on the bottom right-hand side and one thing that isn't adding up
is that there's ten vertices however there should only be eight I have two
squares in here so if I select all of this we can see that I've only selected
eight of the ten now this means that they are some vertexes that are directly
on top of one another to explain this a little bit better what I'm gonna do is
I'm gonna just create a cube you don't have to do this I want to just create a
cube to show you exactly what's going on so here's our cube if I go to our cube
remember when I tried to select all the vertices last time
and I showed you that on the other side I couldn't select this one this is
exactly what's happening with our current verses that are on top of each
other to be able to select a vertex a line or a face that is on top of one
another you have to turn on x-ray up on the top right hand side when you turn
this on you will be able to see through objects and select through objects so
now you can see I can select right the way through in fact I can even select
just the one on the other side so now with that tackled there we know that
there are extra vertices so if I go back into our top view here and move
ourselves over here now if I turn on x-ray and I select everything we can see
that I'm selecting all the vertices now I personally know where these extra
vertices are so just to show you if I can select one here I just turned off
x-ray hit G to move it you can see it's hidden right there another way you can
do this is by turning on x-ray once again you can select whole bunch of
x-rays whole bunch excuse me a whole bunch of vertexes and you see here I
have two vertexes selected when I think I only have one it should be like this
just one of 10 so if I select these two and I hit right click then I can do
merge vertex at Center but let's say you have your floor plan and you have now
hundreds of vertexes in front of you you are not about to go and select each
vertex one by one to find this out don't worry there is something else to do so I
want to undo that last little change that I have here so right here I have
two vertexes make sure you're on x-ray select everything you can do this by clicking a
and then from here I'm going to right click merge vertexes by distance you see
here on the bottom right it said it just removed 2 vertexes and what it's just removed
is by this merge by distance here on the bottom left
by distance its merging any vertices that are closer than 0.0001 of a
millimeter so in other words right on top of each other so if I hit that you
can see once again I'll just update that it removed two vertices and we can go
and check that by selecting the vertex that had two vertices in one point and
moving it and you can see that it is no longer there so that there is how you
can do vertex clean up both manually and automated next let's go about figuring
out your distances now blender has tried here to give you
something to show you distances and that is in the overlay options over here on
the top right there's overlays if you click this on the drop down here you
will see there is something called edge length if you click this nothing will
appear this is because nothing is selected as of yet
if you select everything you will see very faint text here that you can't
really see now if you want to be able to see this they're gonna go here into edit
preferences theme 3d view and there is right the way down here
edge length text let's turn this into a nice bright white color
unfortunately blender doesn't have the option of making this font any bigger or
any more accurate and this is a big one especially for us when we're doing a
solid modelling and precision modeling because we know that this line here is
10.15 however we have gone to 10.1 and you will also see there is a slight
drawback that if I make this line just gonna go and move this I'm hitting Y to
move it and I'm moving it point zero two it has rounded up our measurement so I
wouldn't rely heavily for accurate dimensions on the overlay of length of
edges now if you really want you can go into edge select and you can just click
on edges to be able to see how long they are estimated to be there is an angle
here but I find that the angle just doesn't work even when you do this to a
solid face it gives you some really weird results anyway
so from here inside the edit mode on the left hand side there is the measure tool
before we go into the measure tool and want to remind you about snapping so we
talked about snapping in the last video where we had increment snapping on the
absolute grid this was our grid snapping you can
switch this snapping to be vertex so we can snap things to the vertexes of our
lines so let's click on vertex so then we have the option to be able to snap
things to vertexes so I'm going to go back into our vertex mode to be able to
see all our vertices and then I'm gonna hit on measure now just our
here where there's nothing to measure if you click nothing will happen if you
click and drag it will create a line if you click on that line and pull out it
creates an angle but removes the distance if you click and drag and while
it's selected you can hit X to delete and you can click on a line to select it
to click X to delete so we know that this line here is 10.15 millimeters one
thing that it is pretty nice about blender is that if you're just close to
a vertex it will snap to a vertex I think you can see that I will do my best
to show you you can see here it will snap directly to a vertex that's close
by to it I'm just going to delete all these lines so let's say you have
created a line out and you want to move this point to this vertex well we click
it to be able to drag it around hold down ctrl and now we will be able to
snap it both to the line Center points and to vertices so there you have
it 10.15 unfortunately this is a drawback
of blender we cannot have this parametric parametrically change so if
we go now into edit and let's say we want to be able to edit these you've
just seen that our measure tool has disappeared if we go back into
measurement our measurement appears again so that there is one of the slight
drawbacks and on top of that if we move this now on the (X) oops Y let's say one
millimeter and we go back to our measurement tool this did not move one
millimeter and you will manually have to move this
using our snapping back to the vertex to be able to see our dimensions these
dimensions are great in the sense that they're very accurate but they're a
little bit cumbersome lastly let's go over how to get an angle from this so if
you're wanting an angle I'm going to delete this measurement line you can
have more than one measurement line just by clicking and dragging off to another
corner I'm going to delete these now you click on one you click to the opposite
side where you're trying to get your angle from let's say you were wanting
this angle here we click on our line and drag it out and you can see now we have
this angle measurement come in and once again we hold down ctrl to snap and that
there is how you can get an angle measurement from your drawings now that
you have more control over your vertices and precision drawing I want you to go
over the current plan that you have in your blender setup I want you to do some
measurements some angle measurements try out the overlay see how imprecise
also see how precise you can be using the vertex snapping to get the exact
measurement that you're looking to use I want you to truly make sure that your
drawing is clean with no overlapping vertices to then go on to the next video
where I'll be showing you how to do Fillets and holes last but definitely
not least a big thank you to my patrons you guys are awesome and I would love to
have you come and support me on patreon if you're enjoying these tutorials and
the content that I'm making thanks for watching keep making and like a quest
