Anyone try to define a BSP or BSPT thread in Creo? Do we try custom tools or maybe define it as a tapered mill? Even without any check surfaces the tap I defined will not go past the start surface.
There probably is no specific drilling or milling sequence for tapered threads.
If you use a drilling sequence, you may use a customized cycle to define what is needed for the machine
When using a milling sequence, you could probably use trajectory milling, but you will have to design the curve (as drive surface cut again only allows verticval surfaces, i.e. no taper angle)
