cad choice for parametric modeling

[savat]

Hi.
This is my first post, I am a user of 3ds max, I have a channel vimeo and if you have problems that I have solved in some videos I will be happy to share the notions).
I ended up among you to also have a good shoulder in cad learning for nurbs and related modeling.
I ask my question by exposing 2 softwares (only because they are the ones I have heard to name):

I've heard about rhino well, but I don't know his fields of application, and so his limits.

I am working on the design of a trousse of tricks and it seems to me the suitable object as an example for the following questions:



- is it easy to use rhino for the creation of the functional prototype to be sent to production?

- without anything to remove to rhino, is solidworks (or similar parametric) the most suitable software?

- is the learning curve between the two sw comparable?

- the functionality of hinges, hinges, threads etc. is emulable in rhino using "homologous" libraries?



I apologize if the questions may seem trivial or do not center well the needs that you have for obtaining a product to be put in production but the post arises precisely from the need that someone delegates me on the subject.

Thank you.

I see 137 readings but I have no answers... maybe it is more appropriate to move this post to another section of the forum?
Let me know, thank you.

I don't know rhino well but I can tell you that often the design files that come to me are produced with this software.
solidworks is not the best for the modeling of complex surfaces but still a quarry, and remains one of the easiest cads to learn. I believe that the "goodness" of a software depends on the degree of knowledge that you have in using it, almost everyone succeeds in the objective perhaps with the need to undertake different paths in realization. choose one at the budget you have and study it at the best you will see that it will still be able to realize what you want. I have not understood what you mean by "is it easy to use rhino for the creation of the functional prototype to be sent to production?", however rhho generates mathematical with the desired geometries, depending on the file you carry you can send it to a printer or cam to generate a tool path for cnc lathes or mills.

rhino is not parametric, solidworks yes.
If you work with the surfaces, between the two is definitely rhino that allows you to do everything, solidworks is born to do more.
between the two sw is a cost abyss, I paid it about 1000 heuri.
I have no sw, I have inventor, which currently costs about 2000 euri/year.
They sell it only more for rent and, I think, also sw is commercialized with the same form, while they renovate it and it is yours forever.
hinges, threads etc are things that, with rhino, not practical, I see that there are several plug-ins, but I don't know how they work.
rhino, when I bought it, had a trial version not limited in time but in the number of rescues, so you can hang without the axle of the time passing, of course that even not being able to exceed a certain number of rescues is a nice limitation.
from what I read here, sw is difficult to get in trial, retailers seem reluctant to distribute copies.
I counted 39!

hi, a question: if you only take care of design because you care that the cad is parametric? could also be an explicit.

if you work with the surfaces, between the two is certainly rhino that allows you to do everything

there are surfaces and surfaces... parametric surfaces are more complex to set but give you greater control over geometry

 

[savat]

Meanwhile, thank you for coming.

I did not understand what you mean by "is it easy to use rhino for the creation of the functional prototype to be sent to production? "

I wanted to emphasize the possibility to check the mechanical parts that act as threading, hinges etc. a priori, thus avoiding the phase "first prototype draft printing" was functional.
I know of the price differences between the two (and so much) but this emphasizes that they are two different things.
I believe that the advantage of the parametric is the possibility to always intervene on many aspects (the parameters precisely) while in rhino I have a finite and ostica form to the reprocessing (example that comes to mind is the radius of bevels).
who of you works on prototypes to put in production (see the trousse, a coffee maker, the mechanics of a smartphone...) what does it use?

 

[savat]

hi, a question: if you only take care of design because you care that the cad is parametric? could also be an explicit

hi, I also wanted to face this type of modeling to have a more complete background about the topic. ..modeling hard surfaces in 3ds max is very slow as a process because of the optimizations to be carried out therefore I feel the need for an alternative tool.
In other words... I tend not to deal with design only, do conoto that I am a construction engineer

 

[calacc]

for hard modeling as you call it (superfici, etc...) a good choice could be created. if you talk then put into production Then he convinces me even more. realize that I worked to put into production product projects with models coming from rhino that then I had to engineer with creo to make them buildable. I feel like recommending you an evaluation of qs tool here

 

[Meteor02]

As far as I know about rhino there are plugs that can meet almost all needs, I also got mold designs made with rhino and good quality so while not knowing it I feel like saying that with the right plug it is possible to make the mechanical checks of the case.
as I said solid is perfect for everything but turkey in the use of the surfaces for the rest you have all the analyses you want, from the fem to the simulation of flows, big flaw is the full solid cost is on the 6/7000 heuri.

 

[savat]

as far as I know about rhino there are plugs that can meet almost all needs. . .

I heard about the fathopper plugin for rhino, strong enhancement but it seems to be an absurdity.
At the end of the day, I am interested in being able to enter as much detail as possible on the product to which I work, avoiding to make it unnaturalized by those who will engineer it to make it functional.
If I think about the price, given the exact amount of my work in this field, I should not even watch it solidwork.. .

There are several parametric cads of media facia, also inventor and solid edge are not bad and perhaps inventor is more brought to solid surfaces, but here you should know well what you want and ask for the pima demonstration to buy. then there are high-end cads as creo working very well but have prohibitive costs.
rhino allows you to work at low costs and can be implemented little at a time always with low costs, they told me that it also has a cam module for example. I repeat it is my thought that the final result depends on the skill and knowledge of the designer, every cad has the possibility to get to the same result maybe with different roads and functions, maybe with some more rogna but I think that especially at the beginning the budget is fundamental. Maybe give an eye to some tutorials of the various software to find which can be to you more familiar.

 

[stefanobruno]

perhaps inventor is more brought to solid surfaces

inventor and surfaces are like a Chinese speaking with a Moroccan.

 

[calacc]

here I can deny you because at the time of purchase of creo in 2011 it was not so! I remember that we could tear a discount and we paid half of solidworks... but here you enter the commercial field that does not concern us directly.
I think we should make some demos to look better around...

 

[savat]

inventor and surfaces are like a Chinese speaking with a Moroccan.

If they both speak English they would understand:

but among those who have read this thread and use rhino... is there someone who can assert "yes, use it and with plugins a and b I can parameterize" or "no, point to anything from immediately why rhino does not speak English"?

In the meantime I continue to grow

 

[MarcoBi]

rhino is a surface modeler, and if you know how to use it, you do what you want.
ideal for a designer and with excellent export skills.
with a solid parametric modeler like sw do more.

 

[marcof]

... is there someone who can assert "yes, use it and with the plugins a and b I can parameterize" or "no, point to anything from immediately why rhino does not speak English"?

I don't use it, but I'm more than sure that you can claim that the parameterization you can do with a parameter cad with rhino you can forget it as well as the ease of making complex changes. If you're interested in that look, forget it.

Okay, I think I got an idea:

- The short road.
- solidworks (or who for him)...the long road.

indeed nothing forbids me to walk them both so I will take some time to try before rhino and in the meantime I will stretch my eye to sw.
Thank you for your comments.

and now, to the ricrca of demo!

for the demo of solidworks I see hard,the advantage of using sw is to have the possibility of assembling different parts,in your case it would benefit you by being able to make different types of trousses with common parts,example external equal for all the models you want but different internal divisions for each model,you could see,if you choose rhino,if a plugin,that look case is called rhinoworks,can be helpful

I sincerely recommend you omnicad the cad that we sell, could be of certain part but I feel to intervene because the cad in question is totally parametric associative and uses only the surfaces from when it was born, more 'in the last version already comes out with the formats for 3d machines without going from any converter.
the price is on the standar of others.

Thank you, I'll go take a look as soon as I can...
for now, because of the kookies, I have fb and mail haunted by the companies that want to sell me the softwares I have visited these days
