I've currently got in my program for the machine to go to a certain point
e.g
Code "G91 X20 Z10."
'*
Code "X-20 Z10."
Code "G0 X30."

'*
'This is where I'm hoping to have the following:
'Radius=GetUserDRO(1262)
'Blend radius (tangent) between the last line and the next line
'*
The attached pic should explain it better, is this do-able?

Its not as easy as it looks, you need to know a lot about what is coming up in the next moves, e.g. look ahead. You can't do this with a macro or g-code.

Also what if the rad is too big to fit in the V.

I once asked Art for auto rad and auto chamfer,  I think he is still laughing about it now.

Thanks Graham, I was wondering if it was a bit of a hard one.
Oh well....
