Welcome to PJ's Q&A section. Hello everyone, a lot of people asking me about
the mesh, and how the STL file can be used. There's some restriction in Rhino. I
will say Rhino it's not the best program for the mesh although you can do
a little bit editing, and what that mean is, if you have this mesh import to your
Rhino file. it's hard to edit even though you say you want to turn on a control
points. It is so much point right there. it's really hard to edit, so what we can
do is a simple edit by just putting the logo on the top of things like that.
For example, I have a text PJ right here as a polysurfaces. This is our NURB surface
and when we try to Boolean this, for example, I'll just hit on Boolean. It will
tell me that it is not intersect. So what we need to do is we need to either turn
this into the polysurface in the NURB surface, or we turn this into the mesh as
you can see this is already have a lot of the surface right there. If we turn it
into the poly surface is gonna be a huge file, so we will rather turn this into
the mesh. So I'm just gonna mesh it pretty quick, and then you can preview
for whatever that is. Let's make it more polygon and then you will see something
like this. Okay so what we're gonna do here is if you go to the mesh toolbar,
then you have this as you can do Mesh Boolean, you can do mesh Boolean
difference and things like that, so I'm going to pick up my polysurface and
we're just gonna hide it, and we're gonna have this as a mesh. This is all three
meshes, and then we can Boolean Union, using the Mesh Boolean Union together. Still
this is a closed mesh. That saying all three things are closed mesh, then you
can use the Boolean tool, however, if I have something like this that I download
from the website, and by the way, I download this free model for
CGTrader from the author is Quinton Pilles if I pronounced is correct. He
has a lot of dog model, and this happened to be a free. I'm just download it
for the educational purpose. but I want to show you where I get it, and
then so with this, a lot of time, when you have this kind of a mesh they may not be
a close match. As you can see. it says open mesh. Let's take a look at where it
is broken. We're going to use Analyze and then you have the Edge Tool, and then you
want to click on the object, and it will show. We can zoom in to see where
the naked edge is, so it is right here. If you flip it over, and it's right there.
if it is not too complicated, we can use to fill a mesh hole by clicking on the
edges, so that will fix that one, and then you're gonna come over here to use the
same command to fix that, so they are only few spot need to fixed, and that
will be okay. We can still using this mesh, and then you can put it into your
ring or whatever you want to do with it. However if this is completely open mesh
or is irregular shape, then it will be hard to fix, and I will suggest to use
other program like ZBrush to to fix it. And once you fix it, you can bring back
to the Rhino. So I hope that answer your questions- "Can we import other mesh
object for Rhino to use?" Thank you for watching. I'll see you next!
