After pasting, you do a cut and delete the cuttet part? (I tried to modify the cutted segment, but I got no points to move...)

And if cutted out - I tried to make a rotating profile. But like you can see the surface from this higher part to the ring is not smooth.

ok - just found some flow tuts. Work through this...and then it will work I guess

Flow always deforms!

Not Flow here!

Here it's pure perfect dome geometry without deformation just Boolean union to the ring!

If you see some "fillets" it's just difference of materials translucidy and not geometry filletering!



It's this sort of "perfect" geometry you want ?

Hi Mala, bumps can tend to be better modeled in a displacement brush type application like ZBrush or 3D Coat where you can paint directly on surfaces to tune the bump shapes more finely. It's more difficult to make bumps in a CAD program like MoI.

One way to use Flow that could help though would be to focus on making your bump on a straight shape initially where it will be quite a bit easier to control and reason about, and then map from the straight shape onto your torus using Transform > Deform > Flow mapping from a line onto an arc.

Here's an example using some profile curves like this:


Loft with loft style = "Loose" which makes a much more relaxed surface:


Transform > Deform > Flow from the line backbone to the arc, to map the straight shape into a toroidal shape:

wow...

And you can of course in my above example make an Fillet with "Constant" Dist" against absolutly nothing! :)

Pilou, thank you too for your idea and suggestion. Malheureusement je ne comprend pas "everything against nothing" de toi. (My only one french sentence...)

I tried to find in the flow concept of the attached file.
When flowing it looks like this. Did a workaround with a sweep, then I got a Triple camel...

HI Mala, it doesn't look like the 3DM file was attached.

"everything against nothing"
My example was just normal Boolean Union without any Fillet so can't be more rustic perfect! :)

After if you want fluent transition you can make some fillet or more complex things like "Blend''
(but in this case you must make some trimming around the parts to Blend! )

Hi Mala,

re:

I can't be sure since i didn't see the file to test with, but your result there looks like what would happen if you use Flow to transform just the profile curves and then did a Loft on the transformed profile curves.

Instead you should generate the Loft from the initial profile curves, and you want to flow the lofted object.

Flow is wow-powerful...ok, you know it by yourself...
The loft I made like you Michael, was similar sub optimal like the technic on the bended profile itself. (guess it´s a matter of my skills.)

But what I noticed the first time is the scaleLine-Option in the sweep tool dialogue. Here I was able to bringe a shilhouette line and bring it into the sweep.
The only problem was that the loft was mirroring. I splittet it and flowed it onto the bended spline. Better would be: Not to mirror.
Is it possible not to get the mirror forming? I tried with different placing of the scale line - always mirrored.
Sorry for my hell english...

Is there a workaround to get the flow-object started exactly at beginning of the circle segment?

Normally yes : just put your Base Start Surface where you want it start to the Target surface!

About the subtil difference between CIrcular Fillet and Fillet Const DIstance ;)

About beautiful surface of the Blend Function!

At the end you can modulate the result by Add (and Add / or) Move some points on the perimeters!!!

"Normally yes : just put your Base Start Surface where you want it start to the Target surface! "

I picked the base line of the transfer object and the line for the flow geometry normally. No snapping on it´s endpoints possible, I guess in order to get the flow result exactly.

Hi Mala,

re:

Can you please post the .3dm model file that you're showing in the screenshot?


re:

If you could post the .3dm model file with the piece that is being mirrored that you don't want mirrored that would probably help me to better understand what you're asking here. I can't figure it out from the description and screenshot alone, I need to be able to examine the file.
