Hi Anthony, I'm glad that you've been able to make some progress and that you're liking using MoI!

MoI and Rhino are kind of focused on different goals and so one is not necessarily a complete replacement for the other... For MoI as you've seen the focus is on ease of use and having a fluid workflow and UI. Rhino is more focused on having a large quantity of various kinds of tools, more like a swiss army knife or something like that. Also Rhino is designed to be similar to how AutoCAD functions, which is great if you have a lot of AutoCAD experience but otherwise not so much.

Anyway because of their different goals and priorities it can be useful to use MoI and Rhino in combination with one another - this is also facilitated by the use of the same 3DM file format and you can also use Copy/Paste (ctrl+c/ctrl+v) to move objects back and forth between MoI and Rhino in case you did not find that yet.

re: relative tolerancing - I've been able to adjust Trim for MoI v3 to use the relative tolerance mechanism so that your circle trimming example will work at its small numeric size in MoI v3.


And yes once you've spent some time in MoI's UI you can get pretty hooked on it! :)
