Hi Folks! I'm following this forum for some time now. I really like it but I have a problem so I decided to finally post something. I hope this discussion will also help someone else. How to model gingiva mask on a plateless model the same way like you do on a plate model? When you model gingiva on the plateless library you get gingiva with the round bottom (see picture 1). I need to get a flat bottom on gingiva mask (see pictures 2 and 3) so that it can be printed with the flat side on the printer bed and therefore get a more precise fit with the printed model. I have tried modifying XML files in model creator plate libraries but I didn't manage to make it work as I need it to. Another problem that is chained to this one is how to put occlusion attachments on the plate model? When you use plates you don't need them but in this case, they are needed because the plate won't be used in reality. Please see the pictures for reference.
