MoI to 3D-Coat: needing advice

 From:  Colin

Hi Everyone,

I've just downloaded 3D-Coat in the hope of using it's Voxel Sculpting for some of jewellery models I need to make.
What I'm hoping is that someone can offer me some advice on "what OBJ settings" to use when Exporting from MoI?
Ideally what I'm looking for is if there's "anything specific" that I'd need to beware of when working between MoI & 3D-Coat??
This is totally new ground for me, so forgive me if I'm asking for help with something blatantly obvious?

I've created a basic ring model in MoI to use as my test base & have tried it as both STL & OBJ Import into 3D-Coat.
The MoI Export setting I use for STL's is:
Angle = 3
Divide Larger Than: = 0.5 or 0.2 (I've tried both values)

The resulting STL's will come into the 3DC Voxel room OK, but all of the edges of the model aren't sharp, it's like they've all been notched?
Also tried the OBJ Export, but as I've never needed to use this format before, I'm unfamiliar with what's the best settings to start at?

Here's my 3DM model for those that wish to do their own MoI Export/3DC Import tests.

regards Colin
