Yup, Ominous. In fact, I traded several emails with a tech at Eovia, and also was in discussions on this board and others. Basically, Eovia decided that connecting polylines to polygons was wrong, wrong, wrong and would no longer be permitted by their software. To add further insult to the injury, it seems Carrara now has trouble (at least on the Mac platform) in distinguishing between the two. So you might, say, start with a polygon, empty it, then try to weld some new points into it. And Carrara beeps and throws up that annoying little "This is not allowed on a polygon. Please empty before proceeding." (Or whatever the inane error message is). Sigh. I miss the old methods. And I doubly miss them since I can't really be certain when Carrara will suddenly stop in the middle of a model and refuse to do something. Like the last model I did! (Created cylinder, duplicated three polys to make a short curved section, rotated slightly and started to weld it back in along one edge. First weld, fine. Second weld, all hell broke loose. Almost lost the model completely there -- did lose all my mat zones and my UV map). I keep 4 installed, and if it weren't for some of the new toys I'd do all my modeling there,
