Hi @ryan272727,

Hi!
absolute beginner here. having some trouble getting the “A”'s closed in my design. anybody that is able to take a look and explain to me why that is? i’ve tried obvious things like cap etc. I was thinking maybe I have to try and make it a massive text object and then try to curve it into the top of the ring?
thanks again.

Merged your duplicate post.

for some weird reason it doesn’t, I think it has to do with my red open polysurface not having a closed edge for some reason. I added a picture of what it shows when I try to sweep 2.
I can also upload the file if that’s easier to look at.

Maybe it would help if you upload the file here, @ryan272727?

here it is! could you also look at the lettering that I can’t seem to close? it’s in the blue layer.

use the chain option in blendsrf, or sweep 2 if you want to specify a specific cross section for your transition surface between the red and purple surfaces.
for your text, you have extrusions on when you extrude. You can change this setting by using the UseExtrusions command and setting it to polysurfaces. (best for product design)
simply select all your text, explode it to turn it into surfaces and poly surfaces and then join them all back together.

fwiw, this video will be helpful for you-

on further looking, the “a” in your text has some self intersecting curves which are causing a problem.
explode the curves and run the rebuild command on the curved sections.
use the same degree and point count, and rhino will clean up the curves for you. then rejoin and extrude it again.

What are the ‘design intent specifications’ for said gap?
This fillet looks interesting:
I can check it out soon. bbl.
yeah it’s giving me some trouble. deleted it all and am trying to close it all but keep having naked edge problems. trying to work it out. For the edge I wanted it to be nice and rounded. no serious specifications

Thank you for the amazing reply.
My question to you: Why does chaining the blendsrf work and regular blendsrf doesn’t? I thought I would be faster doing half with regular blendsrf and then to mirror it but kept having edge troubles. Then tried it with the chain option and it worked perfectly. how??

chain is an option in a lot of the tools… it’s typically off by default as it’s a PITA to undo if it chains and you didn’t want it to.
fwiw you can also type the word chain and hit enter in the command line of many tools that don’t have the chain option and it will allow you to chain select edges, curves etc… similar to typing crv in the command line for trim which allows you to trim using an edge instead of having to draw a curve or use a surface.

I need to remember this and try it out a bunch.

I exploded both the polysrfs and checked them out. They looked good, so I went ahead and did a fresh trim on both srfs relative to the fillet, and deleted the duplicate on the lower one, due to removing the symmetrized twin srf.
Long story short, the 0.2mm fillet looks like it worked fine afterward.
I went ahead and took a look at the ‘engraving’ parts. I decided to use ‘planarsrf’ on all the letters and just ‘extrudesrf’ then ‘cap’ and then ‘boolean union’. Ended up with a ‘closed poly’ soo…

I’m not seeing the same thing… maybe the planar srf fixed it or I used a diff file idk…
