Hi, i have a problem with the "Blend" tool.
i cannot blend the RED circles(edges). Because they are not in one pice.
is there a work around for cases like this? i only trimmed the holes with ordinary circles.

The GREEN blend is how it shuld be.
i use the lastets November Beta.

ey blackbird!

you could use the MERGE command to glue those edges together..

BLEND should work then..

Thank you for the example.
Even though I had a shortcut key set up, I cannot believe that I did not know about when and how to use the merge command. :-)
The bulge slider needs to be adjusted, for hole size.

there is one slight problem with the holes on the seam..they edges wont merge there..it's quite a common problem in MOI



..one solution would be, to blend each pair of halves separately and give them a good BOOLEAN UNION afterwards..




~marco

Hey Marco,
"""""""""""and give them a good BOOLEAN UNION afterwards..""""""""""

Just a heads up. When working with "surfaces" like that, you'll want to be using JOIN to stick them together, keeping boolean union for "solids"... Although it works sometimes, it's just a command workflow thats intended...

FYI.

Hi Marco!

Thanks for your awesome explanation on Blending surface edges that are segmented!

Currently, the way MoI is set up, you can only Blend using individual segments of curves residing on the natural (or trimmed) edge of a surface.
Which means you cannot jump over seam-curve intersections!

So for Blending between two holes in separate surfaces, as you show, Blends can only be made between two 'contiguous' edge curves.

As we know, edge curves can be broken into separate pieces even though they look uniform.

The non-UI command 'Merge' will take two selected edge curves and make them one - provided they are not intersected by a seam-curve.

As for those edges intersected by seam-curves, when matching between two surface holes, as you've shown above you have to occasionally "split" up one of the edge curves so that you have essentially a matching curve to Blend to one on each side of a seam-curve intersection.

To split a single edge-curve into multiple separate segments, run the Trim command and use the "Add Trim Points" feature to pick points you want to split. This is essentially the opposite of Merging when used on edge curves.


If anyone reading this post wants to see more application of this - see my tutorial for creating manual fillets using Blend: http://moi3d.com/forum/index.php?webtag=MOI&msg=4607.5




Here, you can see a situation where you need to 'split' up the other edge curve to that you can match an intersected spans of edge curve.







Here, you can see where there is a need to use the 'Merge' command to "heal" two broken edge segments that share a surface.

thank you soo much. this really works!!!!
even the "double Blend" on the seam.
i didnt know the merge tool.
thank you for your help.

I'm really surprised Merge is not a button on the UI. Even though a new button adds complexity to the UI, it seems to be a necessary function.

One problem is that I haven't figured out how to set it up so that there won't be confusion between "Join" and "Merge"... I still have some small amount of hope that I might be able to combine these functions together into a single command.

Join was the tool I was naturally drawn towards when I tried connecting some edges together, so integrating the two seems like a great idea to me, if it's possible.


Martin (2).

That makes sense.

You can use the Merge command on an entire surface, which will link together all the separate segments that lie next to each other - but Merge can only be used when you have those kinds of features selected.
The same with Join and surface edges, also Join and not-edge curve elements.

So I could see Merge command via Join working as well.

Just cut the button in 2 parts ;)

As using Join on edges currently creates a curve, it might make an issue that would need to be addressed, but It'd also make sense to reduce any possibility of confusion between the Merge command and the Boolean Merge tool.

Maybe a 'Create Curve or Edge?' option in the Join tool would work, once edges have been selected.


Martin (2).

Frenchy - do you mean Separate the Join tool? :-)


Martin (2).

<< do you mean Separate the Join tool? :-)

Just Idea :)
Something like this
You can click top or bottom following you want Merge or Join ;)

Good one Pilou! ;-)

Then you could argue for a expandable sub-menu for the "Join" tool set.

My thoughts exactly!

Possible too! :)

Ah..ha-ha-ha!!! Funny!

...now MoI will smite you. :-|

Smite me... O mighty smiter!
