lets say customer can only send you a faceted body

lets say customer can only send you a faceted body

lets say customer can only send you a faceted body

(OP)
am I just out of luck?
is there any way to convert it to anything I can use?
UG is my only system so help me out and how can I use, convert, copy, link , extract this into NX7.5????????

Is it an STL file?

an .obj or stl?

RE: lets say customer can only send you a faceted body

If this is a purchased item, you can simply add it to your Assembly as a faceted Component. However, if it's something that you need to add to or modify then you really need to have them provide you with a solid model. Converting faceted bodies into solids is not easy and unless it's a freeform shape, the level of accuracy of the 'converted' model may not be sufficient so that it's usable as an actual design model.

its a shape that's 3d and I need to modify it and smooth it
so I guess if there is anyway to convert it even with lose of detail i'd take it

cause now I got nothing

RE: lets say customer can only send you a faceted body

Do you have access to a "shape studio" license? If so, have a look at the rapid surfacing tools. It can be tricky to use, but is intended to help create surfaces from faceted bodies.

RE: lets say customer can only send you a faceted body

It depends on the stl file and the shape of the part. John is correct that you may loose accuracy.

2 programs that I use are Rhino 5 and Spaceclaim 2014 with varying results. There is another program called Verisurf but I have not used it.

CJ,

Do you have a file I can try?

It will not download. You need to upload it to the Engineering.com site I think?

doesn't that leave it a faceted body though....
need to clean and trim and fix this shape int a usable product instead a pretty 3d picture

it did indeed bring it in a faceted body and I importing it and should be translating it in?

I agree but if I can get it into nx I can rebuild it but have to have something to start with...

thanks all guess I am out of luck
its the best scan from customer and they brought it together with maya

RE: lets say customer can only send you a faceted body

Here's what i get if i import the .obj file into Rhino, in Rhino convert the "mesh" into Nurbs. Export to Iges and import the Iges into NX...
( The export tool in Rhino isn't perfect, it didn't export everything as Iges , so i exported "everything" again to Step, and then it only exported what the Iges missed... smile
Since the "mesh" consists of "planar" rectangles it becomes converted into Nurbs degree 1x1 faces. ( the rectangles can be twisted.)

If it can be used i don't know, might be better than the facets.

Tomas

thank everyone for going above and beyond on what should have been so easy and yet as you showedwas not


thanks everyone

RE: lets say customer can only send you a faceted body

I got about the same results as Toost using Rhino.

RE: lets say customer can only send you a faceted body

CJ,

I think it's important to point out that a simple conversion isn't very common with faceted models - maybe if we're working with simple parts which are pretty much large facets, like brackets. Once you start working with toroidal, conical or cylindrical surfaces, then you're pretty much going to have to rebuild the model rather than rely on conversion. About the only thing you're left with is asking for a model with finer (smaller) facets - but then your file size will more than likely jump remarkably higher, probably to the point that your computer will either require to translate all night or simply lock up.

Maya for CAD - really? Shame on your customer. I'd think Maya would have IGES output capability. Something doesn't sound right unless it's the scanning that is giving them a faceted result. They need to look at that or give you some tips on working with that sort of data because faceted models typically (note, not ALWAYS) aren't the best means for CAD, especially if you're needing to create the physical part from the data.

RE: lets say customer can only send you a faceted body

Tim, if it's modeled in Maya, it might be modeled there as a "Mesh" only, then there is no better model to get.
Many of these Animation specialist systems will model "meshes" rather than Nurbs beacuse it's "limitless".
And since the output will be images and movies there is no need for better quality.

RE: lets say customer can only send you a faceted body

When CGI (Computer-Generated Imagery) first got going the only software available that proved to be suitable was the NURB based modelers being used by ID (Industrial Design) people, like Alias and Wavefront, and while they were used for some time, eventually facet or mesh-based systems became more popular because, as was alluded to, the smooth solid was no longer needed since rendering tools have always been based on facets anyway and all the smoothing algorithms were already being built into hardware for realtime rendering and into rendering engines for the generation of either still images or animated sequences, so it became a sort of natural technology to use. And while it's easy to go from Nurbs to facets, the reverse is not as simple, hence the dilemma that CJ has found himself in.

RE: lets say customer can only send you a faceted body

Toost,

I realize all of that, but the OP stated there was a scan created somewhere and more than likely there should be an output option for that scan data (NURBS vs polygon model/facet). While I do understand that it's possible to sometimes use faceted models in place of a real CAD model and even machine with faceted models in certain instances, my feeling was (and is) that if there was even a very small chance that a CAD model was going to come into the picture, the whole process should have been a little more well planned prior to settling on a scan output or software that isn't using at least NURBS from the very start. As the OP stated, right now it's nothing more than a pretty picture in Maya. While I am aware of Maya's typical usage (polygon or mesh modeling), I thought it was capable of some NURB modeling, hence why I suggested an IGES output (not knowing what type of model resides in Maya).

Without complete background from start to finish, we're both only speculating, as I'm sure you know. It just drives me a little batty when I see the wrong tool or approach being used for certain things and a guy like me is pulling his hair out trying to make up some ground.
