Grasshopper: extruding font characters, with holes. And draft or taper ~

[clivecarter]

How to extrude font characters that has a hole (or holes, like the 8 or B) and a draft angle taper? This applies to several characters such as:

a b d e g o p q

A B D O P Q R

4 6 8 9 0 and possibly others too.

The example I’ve used is the capital “O” in an isometric view.

I understand that the inner taper is going the same (wrong) way, but the hole is also blocked.

Any thoughts please?

this looks like working well, no need to separate inside/outside curves, uses same Pufferfish taper extrusion component as in your original file:

Inno, thanks; I think this is likely to help others too.
