for some reason, blend does not work here and I can't figure out why. I want a smooth transition on all edges of the hole in this object.

tnx for looking into this!

Hello,

I think there is something wrong around this area (first image).
Those 2 edges can't be merged, there must be a very small gap somewhere.
So I re-trim this area, and then blend the hole in 2 steps.

Hi vimverbe

Never say impossible

blend the two long edges
then add a center line frome each little edges ends
use the line to cut the new long blend (boolean diff)
now you just need to blend each half hole
select all, join
tadaa
possible !

Oops sorry Paq
you're faster than me ;^)

Hey PaQ,
"""""""""""""""""Those 2 edges can't be merged, there must be a very small gap somewhere""""""""""

That juncture is non tangential.

Merge will usually fill in a very small, bad trim gap. But it wont merge a corner point.

Thanks PaQ, I got it now! but when I select the 2 round edges, I can join them and they become one... when zooming in very close, I can see that there is a gap...

Thanks ycarry, also a very good approach!

Hi Wim,

As Burr said (Hi Burr !), it looks like it's more a continuity problem here than a real gap between those 2 edges.
And just to be sure, I'm talking about this merge command : http://moi3d.com/2.0/docs/moi_command_reference10.htm ... it's different from a 'join'.

Hi ycarry,

That's a really good solution too !

Hi PaQ!
I made a video for Wim on the re-trimming...



@Ycarry, works good for "tangency" only, but because the edges are disparate, if you use G2 you will get bad geometry....

But the method is cool for blending and using a divide strategy.

Great Burr, I didn't think to untrim the surface before doing the new cut, good idea !

Wow BurrMan,

your video taught me so many new things in a short time! thanks for that! the only thing I don't grasp is, how does MoI know that when blending the 2 long edges it takes one side only and exactly the one we are interested in at the moment? and again on the other side after that?

thanks for taking your time to do this video!c really enlightening!!!

wim

Hey wim,
I'm not sure i know what exactly you are asking? If there is a time point in the video you can point to that can help describe would help.

I'll guess that you are talking about the blend of the long curves to create the new trim curves?

If thats it, then i didnt blend edges. I copied and pasted them to get curves. Then MoI has a mechanism that knows where you "pick" on objects. So by picking the 2 ends near each other, it knows those are the 2 ends i am targeting.

If thats not it, then more info is needed.

Yes, that is it exactly! thanks again!

Shirley!!!

one must be native english speaker to get that one I presume... ;-)

(surely maybe?)

Hi Wim,
Sorry brother. Yes, it's a play on the word Surely.

Google "Stop calling me Shirley" will reveal my intent! (Comedy)

Take care.

Hilarious! I'm a Nielsen fan! (but I didn't see this movie yet)

thanks!
