what's up guys rozza here again this is part two of the drill modeling series where i go
in and sketch and define my layout sketches after i've inserted the images the purpose of
this step is to capture all the critical dimensions of the part by sketching and
dimensioning these sketches up front it will make it easier to make changes down the road
because you're building intelligence into these sketches so i'll advise you to spend
as much time as possible to get the exact curve you want whether it be using a figuring out what
spline to use to exactly match a curve or adding construction geometry for the setup
if you haven't seen part one go check it out here and follow along and left links in the description
for the following files below now with that out of the way let's get into it okay so
the first thing you want to do is make sure you're in millimeters so just go down here
select millimeters okay so now that you have your layout sketch images all configured now is to
create a layout sketch with all the dimensions and i usually spend a lot of time setting this
up what this does is it adds intelligence to the model so if i want to make changes to something
i can change it in the layout sketch portion so to do that instead of sketching onto these
images what i normally do is just uh create another sketch and i like to start with the right
plane um the reason why is it gives me the most information versus the front or top so that's just
for this particular case so we'll go right since we're going to be focusing only on the
main body today we're just going to be drawing the main body and then in the next series i'll be
adding all the other stuff like the wing and then propeller let's start with a line first
there and let's go with a spline
make sure this is vertical and we're going to make this tangent then we're just gonna
let's lock this guy in real quick so i kind of put it here because you can see
this is where the curvature starts so let's lock in that dimension
let's make this 397. and scoot this guy in a little bit as well and we're going to make this
let's just go 1000 okay and we're gonna grab this if you don't see these control points
make sure you go in right click the spline and make sure you say uh i believe it's display
control polygons so make sure you select that to show so when you see this you'll see these
these control points right here so this yellow and yellow here so now i'll just adjust up
oh it's acting kind of weird okay to kind of match the curvature and you
want to get close you want to get i mean for me i you want to get perfect
so that looks good to me and i'm going to constrain this a little bit further
so i'm going to add a
construction center line grab that there snap it make this tangent
and just kind of tweak the model and then i'm also going to add another
center line there and at an angle so let's make this 38. you can see the influence of this angle
changes the influence of the spline so let's go 39. so actually let's go the other way 37.
okay i like that and just bring it down there and i think that looks good for the spline
okay now we want to also add this line here
this is going to be the bottom half and then let's dimension that so let's say that's 286
bring this guy forward
down
and let's make these vertical select two make that vertical
let's close this guy in just four yep then now we're going to want to add this
bottom curve down here so it's the same thing just gonna add a line
and it seems like it stops around here so i'll say right there then we'll add another spline
so let's select somewhere right there pull it out a little bit and snap it in
to that point so now we're going to modify this a little bit
actually let's make this tangent
okay let's actually lock this in so we're going to give it a dimension
let's say this is 13.
and we'll let's say this is 8 37. and these dimensions won't actually
show in the drawing these are just here so that i can just lock in the dimensions so
let's go there so you can see it takes some tweaking so let's go right there
just grab these handles and tweaking it as we go and to add more
control i i'll do another construction line make this tangent
and this also an angle as well this will just kind of control the spline a little bit further
so we'll say 65 yep that looks good this line here um it's a cut or trim in the part so
for now we'll just leave it out we're concerned with right now is just the body
so right now we just care about how everything flows okay and then one more thing i want to
do is add the um main body attachments like the this portion here the wing and this back piece
so let's do that real quick so we're just going to do a spline right now i'm just hitting s this
is just my shortcut um so that i don't have to go up here and grab the spline so let's go there
and the reason why i don't snap it like right here is because sometimes i have a
hard time trying to grab the spline handle so let's hit ctrl z undo that and i'll actually
select it here and just like snap it somewhere in space and then kind to and then
then kind of drag it around like this a little bit and then let's add that point back
around there and then i'll massage the spline a little bit so there
grab these control points that looks good and let's also draw the top as well
same thing snap it somewhere in space pull out the handle a little bit
and snap in make sure those two connect and then massage the
handles to match the blueprint okay that looks good let's actually lock this guy in
say 241 and let's say 687
and i think that actually everything kind of moves so i'll hit ctrl c and we'll actually lock
this whole thing in real quick so just do that grab the origin let's call this 16 13. okay looks
pretty good um let's make sure everything is it is locked it's not moving okay this
mine's not going anywhere now we are also going to add this back piece as well so let's do that
let's go there there
add another spline
attach that
and we're also going to make this horizontal so let's grab a construction line
grab this point make this tangent tweak if you need to okay that looks good for now
and i'll add this bottom section here on the top view it makes more sense
okay this is good like i said i normally spend a lot of time on my layout sketches
defining them making sure my curves are exact it just makes things a lot easier down the road
uh when you need to change something um but just get it right the first time so spend i like i
said i spent about maybe 10 of my time doing this now we need to add the wing portion so let's do
that real quick let's just draw a construction line there there and let's do another spline
sometimes grabbing these spine handles a little difficult so like
snap that in there okay make sure that's in
actually let's dimension this real quick just lock it in 257 and
617 okay we'll massage this blind a little bit to match
okay it looks good and let's add another spline
snapped it into place and then we're just going to massage this tycota match as well
okay i think that looks good
okay i think we have all our pieces for the right view now also i want to add a construction line
to the very top of the point of the drone this will help me figure out exactly where my front
view is going to go or exactly where my front sketch is going to go so let's grab that make
that tangent now that we have this construction line i'll i also want to make this the highest
point on the spline so let's grab this point hold hold ctrl and select this and make this coincident
and this will make this the highest point on this part and then i want to massage this because now
i went kind of high back to this point let's get this back here and let's dimension that
from the origin let's call this four four three okay um we're actually going to be placing a plane
here reference plane here so that's why that is important because it adds a node that's done don't
forget to save that out now and let's name this right lo right layout okay now let's move over to
the top view as that gives me um the second most information so let's let's sketch on that top view
let's draw the body and i'm actually going to snap to this here
because i want i want to keep that relation so let's do that looks like it changes here
okay and we'll add a spline here
let's make this 86
let's make this a thousand oops ctrl z a thousand
okay let's make this tangent okay snap this to the very nose and let's
drag this guy out a little bit to match okay we're also going to add a tangent constraint
because we're going to mirror this over and we also want to add these guys here
so i actually pivot this because i want this to start at the same point here so let's make this
horizontal same thing horizontal so now that those are located with that top view or with
that right view grab that grab that and make this vertical and then massage this
also we also since we're going to mirror this over we also want to make these tangent as well
so let's grab that point let's add these construction wise here and let's make this tangent
tangent
okay that looks good actually got a little bit wider there okay that looks good there
and oh we actually want to add this back piece so let's go back into it
so add this line then add a spline
like that and we'll just pull that guy out there pull this guy out kind of massage this
to match and i may need to back this guy up a little bit so because it's not lining up there
exactly so no problem let's go back into that right sketch
edit sketch and let's actually push this piece back us a little bit and a good thing we saw
that because now we want to control that by defining it let's give this a dimension of 100
say 103. and from here to that let's give it 119 and we'll make this guy 18 tall that
constrains that a little bit better
now let's go back into this there you go it's actually lining up a lot better
i like that um i can't forget to add a
tangent constraint because we are also mirroring this guy as well so
let's do that tangent okay we're good and we can also do that here as well let's make this tangent
and then let's massage this there and massage this out a little bit
okay that constrains that okay oh that actually is moving so let's make that guy horizontal
okay that should be it now that we have the top let's label that as top layout this is how you
want to lay out your sketches you want to pretty much define anything that's pretty much critical
you want to find in your layout sketches before you even start modeling um so in this this
particular case the main body is important um the wing where it starts is kind of important the this
portion is poor in this back piece so that should give us a good starting point for our surfaces
so normally you want to start with the right it gives you the most information
and then the top also gives you the second most information and like i said these dimensions here
are only there just to kind of lock in the uh dimensions and to add intelligence so let's say
if i want to make this wider down the road i can go into my layout sketches and adjust there okay
this is part two of the drone modeling servicing series so stay tuned for the next one
also if i went too fast just pause the screenshot here of the right view and the top view and just
make sure that your sketch layout has the same dimensions and sketch relations all right guys
i know that was pretty boring but it's essentially for getting this done right up front
i spent about 10 of my time just on this part just dying on the dimensions and getting them all right
you know actually 20 is actually modeling 30 is actually valuing tweaking you know so just spend
the time to make it right up front if you like this video don't forget to give this a thumbs
up and subscribe for the next upcoming video until next time i'll see you guys in the next one later
