Got a question concerning this display issue I encountered.
I have a surface that I was trying to ensure as flat/smooth (like a curve extrusion)… it took me a long time to go back and forth through the different points, aligning them to best possible, as I seen in my monitor zoomed in (right window elevation view).
However I was not able to nail it 100%, and when I tried to measure the discrepancy, I was surprised to discover that it was like 0.1 mm or even nothing 0 mm.
Am I doing something wrong with my modeling process or is there a way to configure some display tolerance? For example if it is equal or less than 0.1mm, I don’t want to see discrepancy on screen. I know that may sound to be a very absurd request, but I don’t want to make it appear wrong on screen if in reality, such discrepancy is neglegible for my current task. Thanks for looking at this!
It controls the display mesh: if yours is set to Jagged and faster, change it to Smooth and slower. If that shows an improvement but you’d like it even smoother then read the available info on mesh settings and explore the Custom option.
If that doesn’t solve your problem then I’m sure someone will be along to take a look at your file shortly, so let us know whether this solves it or not.
Hi, thanks for checking it out. I looked into that panel and same as your screenshot, I have smooth and slower selected.
I tried to click the custom and so far here is what it looks like. (as is). No rush, I appreciate your help or advise you can give at your most convenient time. Thanks!
Well I was going to respond with my usual, this is just the render mesh, nothing is “wrong” and pursuing 0 deviation is a path to madness, but this may be more a case of, “SubD modeling is not appropriate for when you want 0.1mm accuracy.”
How did you align those points? The deviation may be small but it’s clearly there, there are tools for doing that.
I see what you are after and that you tried to manipulate the points on the lower part of the subd in such a way to approach an extrusion like profile. But with Subd’s that have this structure (with the extraordinary vertices in the left and right), it can never get exact.
Hi thanks for the reply and somewhat confirming what crossed my mind earlier about the use of SubD, and probably my method need some correction.
Regarding how I aligned those spots, I usually started with SubD display toggle flat mode, on that right window elevation view, selecting each points and using align (to top /bottom, then to left/right), until I see them like merged into one in appearance. Then I do the same for each next points I marked.
I redo again another round of checking, same process but this time on toggle display smooth, as you see in those screenshots. That’s where I stopped and the best I came up with so far.
Thanks!
Hi thanks for your response. Good to know that, maybe I’ll explore more if those vertices can still be improved. Otherwise, It’s a relief knowing that those display discrepancy will not be an issue in final product. Sometimes it’s easy to get carried away with overly magnified items especially on a big monitor they look scary haha. Have a good day. Thanks!
