I can start the ball rolling from my faffing about
107MB subD from an STL reduced to 147KB

Hey, I downloaded the STL file and, using Blender with an add-on called “QRemeshify”, I converted it into a quad topology mesh.
Then I exported the model as OBJ and imported it into Moi3D using the SubD command.
I’m attaching the OBJ file below, so you have a model in Moi3D to work on that’s lighter than an STL file.
You can also find QRemeshify on GitHub, but maybe from this link (
https://ksami.gumroad.com/l/QRemeshify) you get a version that works with the libraries as well.
However, if you’re dealing with this kind of file, you might want to consider Quad Remesher, which I already mentioned in my previous comment, because it produces a much better remesh.
Cheers

From any of your devasted images above you can have that! (Banana)
Rodin or Tripo

Krea 2
Here i take only one image (you can take 2 images in Krea)
Finally only Krea gives free models :) (from that i speedy test )
But heavy one and triangulated 100 megas
So must use for example some quads decimater so 1 mega! :)
Here the free Instant Mesh
then in Moi with SUbD from Create file
or Import OBJ t by Max Smirnov then Subd_Beta9 or not

This is impressive, really.
i can't wait to see the finished model

I am afraid that is very difficult to have the same result than the first blue image following!
(Best will be to redraw ! :)
You can ehance some regulates inside Instant meshes but...
The Createfrom file will be the better result ... no time now for continue!
Here the SubDBeta9 with small Subd (16 %)
This is just a mirage! :) And a miracle because start image is so devasted! ;)
I am astonished! :) Bon courage for make the same in 3D! Because here it's 10 seconds! :)

Hi pafurijaz,

This is true, but the reconstruction process has a very high learning curve and is better done with tools that are specifically focused on that type of task which MOI is not.
The OP asked:
quote:
scannes items can be exported as stl and obj...so import the obj ...I ll be fine?
The simple answer is "nope, you cannot just open up scan data into MOI and proceed like it was an object you modeled."

Hi pafurijaz,
re:
> because Moi3D can’t recognize the sharp edges of subdivision surfaces
No, not true - edge creasing and weighting are supported by Moi's subdivision surface converter.
But there is not any way in the .obj format to represent edge creasing, you need to use FBX format for that.

Hi Matadem, thanks but it's nothing special, it's a model I made for a beginner user as a starting point to figure out how to do certain things.
I only just realized, after Michael's last reply, that the original message was yours, however Michael answered you about Moi3D.
Anyway, what Geomagic Design does can be done in different ways with Blender too, since it has various mesh modeling tools and some add-ons, but it's not as straightforward as Geomagic Design. Still, it's got a lot of modifiers and, with some experience, it's just as good as certain dedicated apps, but you have to know how to use it and it gets tricky for some things.
I'm attaching an image below of something I worked on in the past: a section of a ship's hull that I reconstructed to create the technical drawings that had been lost over time.
hull section with Blender's Nurbs surfaces and some other add-on for modelling with CAD data
Cheers

You're right, I didn't realize they were two different people, I read the first message carelessly and didn't get that they were two separate persons.
So yeah, you're correct. I kept replying to the user "ado1", thinking he'd started the thread, but it was actually "Matadem", so my replies were all about the follow-up.
Anyway, I didn't know you could get sharp edges with FBX when importing subdivision surfaces, that's really good to know.
By the way, those reverse engineering apps don't do anything special; with a bit of experience you can manage with plenty of programs, like Moi3D and FreeCAD, which has a lot of tools for that. Even with Blender lately there are many tools that help with this, and now you can even create NURBS models directly in Blender, that helped me a ton when working on some scanned parts.
Greetings

That AI approach wins hands down if the file produced is practical and useable
Incomplete scans were always a problem bottleneck in the 3D process
It does the fiddly bits, squaring everything up in 3 dimensions, getting the teeth on the cog right, probably does the pitch diameter/MOD stuff from the raw data
squares up the different holes properly
Amazing
(btw you're all sacked. The robot has been given your job)
On a more serious note if you take the original 100% STL and open it in Meshlab
Then export the mesh to PLY
Then open it in this instant meshes
https://github.com/wjakob/instant-meshes
Save as an OBJ and upload in MOI via the subD
You get a very nice smooth 3DM file to play with, only 20MB
Certainly the best I've managed to do so far, no more monster files!

Just for info Meshy 6 don't make free export but but... Meshy 5 yes (10 free models by month) less detailed than Meshy 6 but...
