Great Update - thanks a ton Michael!!!
Will check it out ASAP.

Good to have the "calculation failed" message - I seem to have that problem a lot ;-)

Illustrator <-> MoI is extremely useful. I don't really enjoy working in Illustrator but some tools are good and some jobs need it, so a fluid interchange it worth a lot.

Everything else looks very helpful as well.

One question: The one area I'd love to see improved is filleting, from more precise/less failures to variable radius and dealing with fillets that end in a single point etc.. Now I read in some threads that this is mainly related to the library you are using. Now I wonder if there is a way to improve this area despite this library or use a different library or is it an area you would recommend using a different software for, even long term? If the latter, do you have a recommendation in the not too expensive range?

Thank you very much!

Tom
