How do folks go about modelling the paragon tapered head tubes like this one: https://www.paragonmachineworks.com/steel-tapered-ec34-ec44-choose-lengt... ? Onlike the Columbus ones I am used to, there is no obvious upper section, lower section, and taper between them that can be easily input into the head tube dialog box. It's just one big taper and it does not appear to even be straight. I think there is some curve to it.
There are some tubes listed in the "standard" head tube library that are labelled "paragon tapered", but they are are incorrect, so they cannot be used. As seen below, the lower diameter is way off from what it should be, somewhere around 46mm.
