I tried to follow this tutorial but I not the same results

Hi ingoenius, do you have a 3DM model file that you can post with the results that you did get? That may help me to give you some advice.

But in general MoI does not have as flexible of a blend mechanism yet as what you see in that video.

For MoI I would probably recommend a slightly different technique to get some more control of the "in between" section.

To start with I drew 4 curves in the Top view, on 2 of them I used revolve to make some starting solids:



Now use Trim to cut the revolved solids with the other profiles to make holes there (holes shown highlighted):



Next I drew an Ellipse in the middle section in beween them. You can alter the shape of this ellipse by scaling it down or stretching it out to adjust the final shape.



Next do a Loft through all 3 sections (it can help a bit when you do the Trim to rotate the revolved surfaces so that your cut does not run through the seam edge of the revolve, otherwise if you do cut through the seam edge you will get 2 edges there which will need to be joined to make a single closed loft profile for this stage):



Now the basic shape is there. The produce the final smoothing, join the new lofted piece with the other 2 to make a solid, then select the sharp edges here:



And use Fillet to smooth them out:




Please let me know if you get stuck on any certain part, and if you can please post a model file of what you currently have that also helps a lot.

We can see at the video some colors appear
Is that "Strength of materials"?
Does it possible in Moi or it's totally another thing?

Does it possible to have in Moi Colors by level?

Hi Pilou,

> Is that "Strength of materials"?

No, it looks to me like a curvature analysis mode with different colors corresponding to different curvature values in the surface.


> Does it possible in Moi or it's totally another thing?

MoI doesn't have anything for that currently. It's kind of a specialized analysis mode.


> Does it possible to have in Moi Colors by level?

It may be possible in the future at some point, but probably not for quite a while. Is there some reason why you are interested in seeing that kind of curvature analysis?

Yes this kind of shading makes my collegue thinking that I'm really smart :)

Good answer, I'm still laughing PaQ :D

Hi PaQ,

:) Well, you could always get the software that was shown in the video for that! That's Catia, probably cost you around $20,000 or so...

about level color : only artistic reason for something like landscaping, and possibility to address snow, waters, vegetation
(not in Moi but in any another 2D progs by these colors)

about "Strength of materials" just if libraries exist and are easily adapted why not put it inside moi
(for architectural or engeneering domain :)
But maybe it's more from solid modelers?

Hi Pilou,

Oh, I see what you mean - a color value by height in z?

But no - that is not at all what was shown in there, it was a curvature analysis based on the curvature values of the surface, not having to do with z values.

As far as I know there is no easily available free library that I could use for structural analysis. It tends to be a complex area that usually has expensive software to handle it.

So the lack of existence of such a library is one problem...

And even if there was such a library, it would still take quite a bit of work to adapt such a thing into MoI.

So that's another reason - if I were to spend time on that I would have to postpone other features because I can't work on many projects all at the same time...

Yes :)

Of course :)
