Hi Michael,

Here's a little regression, nothing very important, in the meshing option when exporting a file.
Emptying field like 'divide larger than' doesn't disable/reset the option anymore, you need to enter 0 to overwrite previous value and disable the feature.

I don't know if it's an intended behavior.
Sorry if it has already be reported.

Cheers.
