hi it's Loan from Gubutek again in the previous part of this tutorial we learned how to import
an stl mesh into fusion 360, convert it into solid body and then do some basic modifications.
In that way, the advantage is that you can use the
solid workspace to do all of the modificatiosn that you want.
It's easier that way but the trade-off we will need to do is uh we need to reduce the mesh
size to less than ten thousand facets or elements that happens um because uh
Fusion 360 cannot handle more than ten thousand elements at the same time (Solid workspace) so
we're gonna have a less smooth model and it's not at high resolution like the original one.
so in this part of the video i'm gonna show you how to edit the mesh within the mesh workspace.
You want to work everything in the mesh workspace so you don't need to
reduce the uh the mesh size of course again you cannot use this solid workbench to do
some modifications but it still be able to do with using the mesh workspace that we can use
the combined function of it let's have a look of the
model i'm gonna show you now first we import the same model which is the rhinohanger.stl
okay so this is our model, and if you remember in the first tutorial
i was talking about how to change instead of this original hole to this screw head hole.
I made a model for it already. I have a FreeCAD model of this one and i have
the stl file so i'm going to import that into the fusion 360 too to combine them together.
You can choose insert and go to screw head too okay so now i have the screw head
of it right here let's take it out to have a look
and you see the screw head the back have to
be uh like this with the small part up high so i'm gonna rotate this one a like this
okay let's see how it look okay so it's good
okay so now we have two different meshes the first one is the rhinohanger and the second one
is screwhead2 . The general idea is to combine these two parts together in the mesh workbench
The thing is if you just simply combine these two together and you and use the thing it's
gonna make a weird combination let let me show you how this um let me move the screw
head into the middle of the thing screw it okay RIGHT okay let's say i move it
let's zoom a little bit to here
31.5
minus 31.6
25 0.4 maybe before okay so it's gonna be this mesh right in the surface of the back of the rhino
but we also want to move it into the middle of the of the rhino head so we're gonna move again and
just see like
go to the back okay so we move it here oh i do the wrong one cancel oh yeah okay so screwhead
move we gonna move it through the middle on the screw head and a little bit down like this
just an example because when you do the thing you can choose whatever you want okay so it's okay now
it's right here in the middle okay but i want it to be at the surface also so i'm gonna move them
- 31.4mm okay so now you have the screw head right inside basically we can use the mesh
workspace to do the work here and in the modification you have to combine so as i told
you before if we just simply make the cut of this part out of the of the rhino you're gonna see the
the head is weird i will show you now so the target body we choose the rhino head and the
tool body is screwhead and remember to keep tool and we're going to use the cut one so when we cut
i need some time to work for that this one okay and here is the cut result okay let's
hide the screwhead so you can see basically the cutter is only get whatever inside the
it's like a mold cut the inside the screw head but this is not what we want.
We want an empty space because we can uh put the screw head inside it so this is not the way we do.
what we can do now is first we cut a hole a square hole at the outside part
of the screw head and then we can combine the screwhead with the head together so uh
let's ctrl z okay so we keep screwhead as is. let's make a a new one so you can create uh
a go to the solid model then create a sketch go to back of it okay so we can um cut it from here okay
here i'm gonna make a sketch right on this surface okay with the i'm going to
choose the outside of this mesh at the sketch. so now you have it right here okay what we want
if we cut from this surface back with the side of this the screw head is the thickness is 8.5
so let's make an extrude the new body yeah we make it new body so we can make distance is
yeah distance we're going to put it 8.5
perfect so it was you have extrude and it was inside so let's drag it outside here
go to the right surface see it easily yeah i'm gonna drag it up to here 3.5
uh 8.6 maybe 8.6 perfect so it's okay with 8.6 now we have an extruder block right there here
so what we do is we're gonna convert it this one back to mesh here create a mesh from that one
okay select body modify and okay so now it's become a mesh now what we do is yield the rhino
minus the body five and then plus the screw head too okay so go to the combine select the target
body and then select the body five is we want to cut it out so cut it out right here and we
want to keep the tool okay and give it some time to work again because fusion 360 is not a strong
software to working with mesh you want to do that you do it with Blender but i just
show you one possibility how to do it with fusion 360 thing. later i'm going to show you a video on
how to do it with blender and you will appreciate the speed and the uh the convenience of it but of
course with fusion 360 you can modify and do in the solidworkspace much more easier
okay so it's done if we hide this screw head and the body part you're gonna see that it have
a hole that cut right here in the middle of the rhino head
The last step is we're gonna combine the rhino head with the screw head okay so another combine
choose rhino at the target and choose screw head at the tool and in the option you can
you join or merge uh to me they are the same so i'm gonna go join okay uh yeah
okay so it finished the combine of the screw head and the rhino head. Let's
exported to stl file and then we can check in the slicer to see if we got exactly what we want
You know there's no way to know and you have to check on it
so right click on file and then export mesh body okay when you save
you can save it at the name i think i'm gonna have here rhino screwhead okay the 3mf but
you can also save as object or stl they're all the same they work with all the slicers
Now go to the process slicer let's add the one that we just created
this is the rhino screw head 3mf okay here okay let's move it into the middle and um we can place
this on this face to see now we can just slide Of course the look shows that it's the correct
uh rhino head with the screw head but you know you can always check and here
okay congratulations we have the that we can make a hole and cut into the mesh of the
rhino head okay so using this mesh workbench you don't need to convert it to solid
you can keep the original resolution which is 236 900 faces that we have in a mesh
and of course the the disadvantage of it is that you have to walk around a little bit create some
solid parts and then plus and minus them but it's doable uh compared to the solid workspace when
it's easier in terms of all the solid to work with it but you lose the resolution
so this is the trade-off you need to think if you need to do a lot of modifications
you go with solid if you need to do some simple uh modifications you go
with mesh workbench and they both work of course this is not the advantage of
fusion 360 to work with mesh you will see uh differences in term of processing and and the
convenience of it but it show you one possibility of course later i'm going to show you some other
video how to do with Blender and you will see the difference um so
that's all for today if you have any question any concern just let me know right below i'm more than
happy to help and if you want to know more about this stl editing in other software like blender
or a tinkercad you can subscribe to my channel and we see again in the next video happy making
