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.

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.
