Hi davide,

MoI works well for building watertight solids, and also for exchanging models with SolidWorks and also Rhino.

In fact MoI's main file format is the same 3DM format as Rhino, so you can just open up 3DM files you save in MoI with Rhino. You can also use Ctrl+C/Ctrl+V copy and paste to move objects back and forth between MoI and Rhino as well, so they work well in combination with each other.

For transferring to SolidWorks, SolidWorks also has a 3DM file import or you can use STEP files as another way for moving data from MoI into SolidWorks.

You can test this with the MoI trial version.


> Also what about training / education options?

Rhino has more for this - the main resources for MoI education are to read the help file here: http://moi3d.com/3.0/docs/moi_help.htm - read the introduction section to get a general overview, and watch the tutorial videos: http://moi3d.com/3.0/docs/tutorials.htm

Rhino has more training materials for it - you can actually do many Rhino tutorials in MoI as well, especially ones that focus on basic NURBS modeling strategies like how to set up sweeps, doing boolean operations etc...

There is a fair amount of similarity between Rhino and MoI because I created both of them. But the focus for MoI is much more about making a streamlined and easier to learn type of CAD software. The focus in Rhino is more about being comfortable to AutoCAD users and providing a lot of different tools.

The best way to see if Rhino or MoI would work well for you is to get the trial versions of both and spend a little time messing around with them.
