yes both work, just wanted to know witch method you will use fot this.

Hi mir4ea, I would myself probably go with the filleting method, just because it can generally be difficult to control the surface shape in pinched-down areas.

But it also depends on what in particular you want to control - the filleting method lets you control the end cap shape more easily since you can build a more simplified surface for it but you are relying on filleting to generate some pieces for you instead.

One thing that can sometimes help with using Network for "collapsing down tip" areas is to put in a small circle or arc curve near the tip, that kind of tends to make the shape even out somewhat as it comes together, a couple of examples of that here:

In the end, there is not any "one absolute right way" to do stuff, it can sometimes just depend on your personal preference.

Just in general though I find it difficult to get good surface quality when you're trying to force the surface through too many different shapes all in one single surfacing attempt. So building some broad forms separately and using fillets for transitions can tend be good instead of trying to model them all at once.

Also if you need to make a model that is sort of blobby / melted looking stuff like that can tend to work better in a sub-d modeling program rather than in NURBS.

Regarding French's response in which he pointed out that the sketches do not actually intersect.

Can someone post how to fix this in MoI (rotating into place and scaling, or aligning, or whatever approach works best). I have not run into this issue as I use snaps both in Rhino and MoI. In the event that I have to use traditional CAD tools I constrain all my sketches. I know how to fix issues like this in other programs, but in Rhino & MoI I have not run into this as I use the snaps. Repairing the sketch issue would be a great thing to know (with an image or three to help my visual brain).

thanks to anyone who knocks it out.

Maybe like this :)

My favorite tool! The Line Line on the Curve selected! :)
Just 4 clicks! And you can choice Uniform, Strech or None! Copy or Not! (here the None's case never works because ellipse's size is smaller than the biggest size of the curve )


You can of course make clicks 1 & 2 anywhere on the curve following wished result! Above it was curve's extremities

heere it was along the curve!



PS Ellipses are similar (just perspective's effect ! ) Curves are different in x,y or x,y,z following Stretch or Uniform
You can have a same result with the "Edit Frame" (you can see its handles on the image) but it's less practical in some cases!
Select / Move/ Adjust Axe of Symmetry / Rotation / Adjust on X, / Adjust on Y / Adjust on Z etc...

Nice! Definitely one technique to add to the ol' toolbox.

Reminds me of using align in AutoCAD years ago. You could move, align, scale at the same time. Was very handy moving sketches around and resizing them. I just need to mess around in Rhino now to see if their solution is as easy in MoI.

Thanks for posting that.

Good example Pilou
and YES -mjs-it reminds me too using align in ACAD years ago !

Frenchy Pilou, super kool!
I never know about it and spend a lot of time trying to intersect those curves..

Tried this method but it's not so good if you have more than 1 curve that you have to match. Because it stretches all curve ..

This method works one by one! ;)

Example ?

Just found the way how to make this cap perfectly smooth. I just blend with G1 naked edges on the end)! Works great)

Just verify for some complex forms that all connexions' surfaces are well "waterproof"!

"YES -mjs-it reminds me too using align in ACAD years ago !"

Ok, found it in Rhino.

Orient with the option SCALE set to yes.

Not quite ACAD but Rhino and MoI are hand holders in my toolbox.
