Probably way off beam---does this "in principle" look anything like what is wanted to be obtained in MoI?

But then I had no need to go scale array either--did I!

Hi Michael,

Yes, in many cases it is possible to obtain the same result of a Rail Revolve operation using the Sweep command. But I think there are some exceptions.

The following example uses a 3D path, and the results produced by MoI and Rhino are different:





Rotating the curve 1 by 90° (2), then scaling it by 1 direction twice (3-4), you get the curve for a sweep.



Unfortunately, the surfaces have some artifacts, but in principle this works.



Anyway, as people often says, "Rome has not been done in a day....". And I think that MoI, as a joung product, is much more than expected!

Hi Artaud, yeah the sweep alternative is more for things that follow a longer path instead of being like a dome, more like the scroll shape that you were asking about originally.

MoI's sweep will not work for a dome-like shape currently but I do want to add a kind of pivoting sweep mechanism in later on.


Can you please post the .3dm files of the curves and the results from Rhino so I can use them for testing?

Thanks,
- Michael

Hi Michael,

... I just abandoned the file, without saving it. But it is fast to recreate. You will find it attached.

Notice that the curves (the ellipse and the curve) have been done in Moi then pasted in Rhino.
Then I used RailRevolve command, with ScaleHeight option = On.

BTW, I just published a small article on modeling the Fender guitar on my website. Below is the link:

Sorry, the article is in Italian. But maybe someone can use the pictures.

Actually I am playing modeling a violin. It is an interesting challenge... and I have a lot of fun modeling with MoI.

BTW, did you publish Italian U.I.? I used Italian screen dumps for the article, and it would be better that people that will download the software find consistency between images and the version.
