Throughout my modeling work, I'm struggling with a question: to blend or not to blend.
Some opinion/observation from people on this forum are very impressive to me, e.g.
: Do not define your fillets in curves, build surfaces oversize and use surface blending commands near the end of design. [source]
To be honest, from the beginning, I shunned the use of blends and tried to define highly curved splines as sections for surfacing. I knew this might be problematic. But it was really difficult to resist the temptation to build the model in a straightforward way and without bothering to leave space/oversize for later blends.
After suffering endless trouble caused by those highly curved sections, I think that it's a big mistake to shun blends.
However, to "build surfaces oversize" is not an easy job. At the intersection of two surfaces, the space for later blends need to be considered. This seems to be very tricky. My approach is to sweep a triangle along the intersection curve to preserve space for the later blends. But this seems not to be a good practice.
"Build surfaces oversize" and "blending ... near the end" are the start and end of a long modeling project. It's difficult for me to present a real model example for the problem.
I would be grateful for your possible suggestions. If my question is too abstract to deal with, please simply ignore it.
Thanks!
