yeah, auto desk has a bunch of free to use soft now as you may already know. I have found some of it to be really quite useful for certain things. While you are looking at it, you may want to also check in with their "123" stuff. They have a lot more free models now.
with that in mind, I would also like to ask if anyone can give personal recommendations for a good soft to clean up photo geometry. I am aware of autodesk remake/Memento Beta, but that is subscription and windows only (i think it is windows only).
Any standalone multi OS soft?
Sorry, there is a MAC version of remake. It is in beta and can be used now
"MAC version is BETA and users may encounter some stability issues that will not be present in the commercially available WIN version.
