Problem BlendSrf 3.3dm.zip (3.0 MB)
In the attached I a trying to do a blendsrf. I keep getting a weird, distorted surface as a result.
your surface is massively massively over defined.
even rebuilding it to half the spans its too much.
but it will blend just fine once you get it in a more reasonable state and refit the trim edges
in the second image this trim edge is bad… untrim it, keep your trim objects, explode the curves, then join and rebuild those curves, retrim that edge then refit the trim- (do both edges if you want to be picky)
it blends fine when you fix the edges,
I’m curious, where did this surface come from and why it is so dense?
What is the end result desired for this?
I was in the process of creating these. I was working iteratively. In the opening example, I started with plan measuments. Those were all transverse cross-sections. They did not follow the path of the pipe.
In the process of converting the plan cross sections into paths the follow the pipe.
I took overly complicted parts like the original, created section lines, simplified those lines.
The original had a realy bad section that cut out and wanted to fill with a blend.
ok, but even those originals could benefit from massive simplification via rebuild.
simpler surfaces will always yield easier cleaner results.
there is one true unbreakable rule for 3d modeling
bad stuff in= bad stuff out
everytime.
take a look at this modeling tutorial series. Even if you are a 30 year pro you will learn, or in my case, remember these principals, which will make for better models.
A little time spent making these “cleaner” will yield great benefit in not having to fight stuff so much.
