Full Version: Opening OBJ and STLs in MOI

Show messages:  1-3  4-23  24-29

Thank you Metin & Michael.
Always a pleasure to be answered so quickly and so in details. Waiting for the release of V4, so Michael, keep up the good work, and thank you.
Sincerely,
Rudy

Hi Rudy,

for importing STLs you can try my script here:

Thank you Ralf. Will try.
I have tried Max's script, and I guess after MOI working for a while to open a 150000 file, did not show up anything. ...perhaps the model was too complex, or will try closing the several programs opened during that time.
Thank you very much to everyone. And to Michael.
Ciao,
Rudy

Hi Rudy, as I've mentioned above that type of dense polygon data isn't suitable for importing into MoI with an individual trimmed surface for each little polygon. NURBS solids are meant to have larger smooth trimmed surfaces and not hundreds of thousands of little flat facets.

You need to use a polygon mesh editing program to work with that type of 3D model data - MoI isn't the right tool for that task.

There are some specialized programs that can help to "reverse engineer" smooth surfaces from dense polygon scanned data, but it's a pretty difficult and involved process. See here for some links: http://moi3d.com/forum/index.php?webtag=MOI&msg=8460.2

Hi Rudy, maybe you could describe what it is you are trying to do with these .obj and .stl files - like what is the goal you're trying to achieve by loading them into MoI? And maybe show an example of what the files look like. That might make it easier to give some better advice on possible options.

Hi Michael, thank you for all your time.

Actually, you are right on, no need to really to see them in MOI, as they are organic models, probably done in Zbrush or similar. As far the OBJ files, wanted to output them in STLs ready for printing. I was just curious to see them in MOI, as it is the only 3D program I am using. Thank you Michael for all the support and knowledge.
Ciao,
Rudy

Michael -

Speaking from my own experience, there have been times I've wanted to 3D print a free model from Thingiverse.com. Usually the only file format that is published is STL. Often I want to modify the model to fit my own requirements, so I end up creating my own model in MoI. I'm talking about models that are mechanical in nature rather than organic shapes. It's difficult because you have to somehow derive all the dimensions from a picture. If the STL can be brought into MoI it can at least serve as an accurate guide for drawing new curves and constructing the model with NURBS.

Hi Ed, I'm kind of hesitant to focus on that type of reverse engineering workflow because STL triangulated data would need to be represented as a different category of object in MoI and that brings a lot of issues with people wondering why their imported STL data doesn't behave the same or interact with other regular objects drawn in MoI.

It will probably happen eventually.

Hi all,

what i don't quite understand with brining in an .stl model and the request for .stl import,
why don't people use not the free Meshlab and import there the .stl and save as .obj?

Meshlab is such a well known software in 3D circles.

Stefan

Hello Stefan!

@You : "...why don't people..."

Hmmm...good question :)

I totally agree with you!

---

Thank you Stefan

---

You're welcome Rudy.

Regards
Stefan

I was not able to get the script to run. Am I doing something wrong?

Hi MichaelT, it looks like you've got it set up ok there. What folder have you placed those 2 files "_STLimport.htm" and "_STLimport.js" into though?

- Michael

In here:

Mmmh,
seems to be the right place for _STLimport.htm and _STLimport.js...

FOR MOI V4 BETA FEB-09-2018

What happens if you write _STLimport into the console?

Tried that too. Nothing. No error, just nothing happens.

---

Hi Michael,
i am on Mac and i never tested the script on Win...
But if there would be a problem on Windows at least you shoud get an error..

If you are using the latest V4beta Feb-09 Version it should work with this command folder at AppData..
What happens if you put the two files into the original commands folder?

---

Hi Ralf, I've tried that as well, but still nothing.

---

Just installed V4 on my Windows laptop and tested _STLimport script..
No problems it works...

Perhaps the download of the script files was not proper...
No more ideas why its not working for you... :-(
