i know how to create hole in slab or roof..
but mesh is impossible.. why? is there a any solution or method to create mesh hole with API.
thanks
i'm developing archicad 9...
next line is sample code..
static void Do_Poly_NewHole (void)

ACAPI_OpenUndoableSession ("Do_Poly_NewHole");

WriteReport_Alert ("No element was clicked");
return;

return;
