My understanding of antenna modeling is that sharp corners or
connecting points should be avoided as they can create errors.
The question I ask is what constitutes a sharp angle ?
I am assuming that it is the capacitance at the connection is the
problem. If so
is the corner of a quad a problem or is a delta feed point on a dipole
a problem ?
I see many instances of quads being modeled and also " V" wire antennas
each without a correcting "gusset" at the corners. So when is an angle
termed to be sharp?

When it is at a current maximum. At a voltage maximum it's irrelevant.
Just my opinion.

On second thought, it's all irrelevant. The feed lines of a balance
feed attach at the center of the dipole. That's a right angle bend at
a current maximum. Must not be a problem - everybody does it - Hi!
