import from rhino after turning into nurbs

[lelecaggia]

Guys, I have a problem I can't get out of. .
an architect, he modeled two details with 4d cinema and then passed it to rhino for conversion.
I already tried to let him use the _meshtonurb command to turn mesh into nurbs, but the result is that an object is transformed, while the second does not even appear to me. It's like it doesn't exist.
I have to design the injection mold, does anyone know how to help me?
Are there any other ways or formats I can use to convert the file so you can work it with inventor?
Thank you in advance to all and wish you a good job. . .

Did you try to open it as it is with inventor?
otherwise if you have the ultimate product design suite, you should have installed alias. Try to open it with this.

What do you mean he passed it to rhino for conversion? What kind of object is it? if it has double curvatures will never be able to convert anything...but to model details in 4d cinema.

as it is, it opens it. .
Unfortunately it is a design object that has multiple curves.
the choice of 4d cinema not even I do, but the architect who commissioned the work uses only this program unfortunately.
with alias I didn't try to tell you the truth, I'll get a test right away.
Thank you for now.

4d cinema works in polygonal, and however even if it had used the nurbs, present, although at the base level, surely exported in a mesh format. do this, export, or tell him to export (if you even tell him to go to rhino would be the top ) in obj. download tsplines for rhino, it's a trial that lasts a month. is a plugin that activates polygonal modeling in rhino, but based on nurbs, which can also convert imported polygonal models into obj. practically you have to reverse engineering, but not from a stl, from a simple polygonal model, and tsplines does just that. you will have a nurbs model, where you will have to put your hands back, if you have to make a mold.
