To keep the amount of reworking as low as possible I try to minimize the use of supports and print parts right on the build platform surface. This works for some, but far not for all parts, as important support structures are missing and must be manually included via Meshmixer & Co. I would love an option in Preform to keep the part on the build platform surface and attach supports either from the part itself (internal supports) and/or additionally (if needed) from outside the part from the build platform (as meshmixer would do).
Hope that you guys agree?
