sofa

[Nibor]

Who can give me a few tips to shape this couch?
I'm in serious trouble and I can't combine anything!
Thank you:

But you have to shape that one right there? because of 3d sofas on the net there are hundreds.qui There is an example of sofas similar to yours, maybe you could also fit some parts you find to get to yours. also looks at the precise brand, because companies often make available 3d of their products.
However such a thing in rhino is modeled more easily with specific plugins as tsplines o clayoo (the latter has a 90-day beta)
otherwise try to take a look qui, how to shape a pillow, you can start there.

 

[Nibor]

hello erni thank you so much for your answer
I have to shape exactly this photo and I have to do it for a company where I'm doing the internship and there's no model already I should do it, I'm in serious difficulty... now I try to follow your directions
I thank you

So it must be a nurbs model, since it is a project? However the above plugins also convert polygonal models into nurbs, (the best in this is clayo) and the hypothesis of finding similar parts that you can adapt is not entirely in the air, you could try. in this sense also tries to take a look qui, there are hundreds of sofas, free.however I think you have to understand where the buttons are, and generate a lattice that makes you happen control points just according to your scheme, you can also use paneling tools to bake the surfaces, in a custom way.

the project has already been done and the sofa already' production, I only have to model it in 3d ... unfortunately I am at first arms with rhino and I can not move with ease for the moment I modeled simple sofas and with volumetric famine quite uniform and constant (I have to study)

Thank you:

Well, you're just gonna say, you've chosen a nice pear cat.

I can give you an idea of how to set it, in the enclosed rhino file you will find curves (red and green) select them all and then from the _networksrf command.
the result must look like that of the image.

Once you understand the method, you will have to adapt it to your sofa.
good work:biggrin:

 

[enri]

do first scan it, or with sw using photos, or with kinetics, which you can lend, the sw is free, save a lot of time. the folds will never come, you have to put with a polygonal modeler, and do everything there.

Hello, Marius, thank you. Is that a demo file you sent me?
How do I behave?
Thank you.

 

[Nibor]

My job is to try to model it not to scan it, what is sw and kinetics? ... what are the most simple polygonal models to use and in Italian?
thanks erni

 

[enri]

polygonal and in Italian only blender. I think the best.
by sw I meant software, kinetic is that of xbox, it is also used for 3d scans, obviously it does not have a high tolerance, but it does not serve in many cases, qui find some info. you can also buy separately and costs a hundred euros.

 

[Nibor]

Anyway, guys, I have to model it in rhino. I only have this in the middle. encourage me

 

[marcof]

the project has already been done and the sofa already production, I just have to model it in 3d...

I can ask why you need to model it, being that sofa already in production, so already designed?

Because there's no 3D file and the company needs this file and others I'm already doing and I'm going to have to do it, but this kind of sofa I don't know how to model

I have no idea how much, and especially if, they pay you by doing an internship. but model it from scratch to have a 3d that does not serve for design (I imagine to make renderings or similar things), with the availability of the already made sofa does not make sense. make a 3d scan that in the end costs less (always pay you...) and you will have the model in a very short time.
If they make you work for free then go to rhino and... best wishes, you need it:redface:

We try to understand the purpose of modeling, since it's already in production.

prepare virtual settings for a catalogue?
In this case it seems useless to me to replicate the surface of the skin, since a good rendering program can apply the texture by giving it a three-dimensional effect. (see the image of the sketch that I sketched )

If the 3d model is given to a company specialized in this type of work, they will certainly be equipped with programs at the height of the situation.

If you have to do it, rhino is not enough for you. You could use blender that turns out to be free with open source license. but to get good results it takes experience and hours of work.

if you have to model it, then follow the advice of enri, downloaded clayoo (free beta and working for 90 days after registration )
http://www.clayoo.com/page/downloadand learn how to use it, it's a polygonal modeler (mesh) with the possibility to convert mesh into cloud surfaces.

 

[Nibor]

boys are an intern and as a task they gave me
this, unfortunately it is useless to try to understand why I have to do it
I just have to do it and they don't want me to apply a texuture.
mariuss but with the first advice you gave me, can't I? ? ?
If I didn't understand how you did it... with t-spline maybe it's more feasible? ?
I don't know if to start, I have to create the whole volume or not?
Thank you.

Let it go, with rhino it is very difficult to make the submerged buttons in the pillow, I did some tests. Look at me. qui as are the techniques to make this type of objects, there are various software, but the technique is very similar, there is also something for tspline, but no buttons, however the system is the same. with clayoo or tsplines (try both from 30 to 90 days) you create the seat, where will be the buttons, then define precisely where will be all the points, then the polygonal subdivisions will be consequent to this, around each point you have to make a polygonal circle, adding points of control, then deepen the point translating it down, so you can try the button, in short, leave a little space, the folds otherwise take a piece of sofa between those placed above, size, add, scale etc., and the same is fine.

Thanks erni, now it's a few days to the sea and then I put myself under and I let you know, the folds are not very important that there are, the important thing is the capitonnè effect ... I will try with t-spline .... thanks again:finger::wink:
