I have adapted a c-hook developed for mcam 2022 for mcam 2024, and a function stopped working correctly. I use BreakManyPieces like this: void splitSpline() { bool succf = false; EptrArray ents_to_break, ents_new, ents_wrong; BreakManyPiecesParams brk_par(true, 0.02); brk_par.m_Curves = true; brk_par.m_Dispose = PostBreakAction::Keep; brk_par.m_Method = SegmentationMethod::Tolerance; ents_to_break.RemoveAll(); NoStackEnt(entity); DB_LIST_ENT_PTR pFound = nullptr; DB_LIST_ENT_PTR pDB = db_start; do { get_raw_ent(false, &pDB, &pFound, &entity, ALIVE_BIT, S_ID | NB_ID, &succf); if (succf) { ents_to_break.Add(pFound); } } while (succf); if (ents_to_break.GetSize() > 0) { auto res = BreakManyPieces(ents_to_break, brk_par, ents_new, ents_wrong); //res is true //ents_to_break is 1 //ents_new.count is 2 //ents_wrong.count is 0 } } This ususally break my splines correctly but in mcam 2024 this happen: (Original entity) It breaks this spline in just two lines. If I do the same operation using the ribbon command with the same parameters it works correctly:

I add a note for future reference if you pass nullptr to the method it would crash, you have to do something like this: DB_LIST_ENT_PTR e = nullptr; mirror_silent(&e, true, false, mirrorVector, 1, &succf);

Email sent, thank you

Mastercam 2022, I have LatheBarStock.dll (provided by cnc software) but it require to manually open and close the stock menu in order to make the settings effective.

I need to set the stock for a lathe, is this possible? All I can see is MillStock. I also need to set the chucks, can I do it? Thanks

Were you able to set up the stock? I'm trying to do the same thing.
