Same here. STL import as mesh or solid is a bullet point on this release on both the Mac and iPad but the STL import process does not offer that option.
Wow, I’ve been waiting for this for years! But I’m afraid you’ve recently been superseded by text2cad.
That’s on us. We held this feature back because it wasn’t ready yet, but we forgot to remove it from the What’s New notes in the App Store and Microsoft Store.
We can’t edit those notes after release, but our next update will set the record straight. In the meantime, we’re working to ship the feature as soon as we can (already available for the Gamma group)
