You can EXPORT STL files, you will be unable to IMPORT them.
Why? Could barely import them now...That is so messed up.....
Never had any real success importing. Very glad I will still be able to export for slicing and printing.
If meshes are core to your workflow, it's probably best to not upgrade to 2018.1 and wait until a later release where mesh support is re-enabled.
I'm trying to understand your comment, but it doesn't make any sense especially with respect to the topic of this thread.Any either pay a support contract without being able to actually make use of it or pay the penalty of getting back into support when it has expired in the mean time :/
