hi klox
I designed this tool in onecnc using solid moddeling
i used core and cavity options within onecnc
to produce tool
but remember i design tools for a living
runners etc i did from my skills
there are no facilities in onecnc for hot tip and runners
though you can produce them from experiance
but don't underestimate onecnc most of the tools are there
and you never know with onecnc
with its split lines which is available with expert
it won't belong before the developers bring the tools you where
asking about into onecnc
best regards
peter
