Some nurbs tools arrive in Su!
Bravo!

[Click Draw]

Yes....this script will be a very good ASSet to my collection!

Congratulations, TIG!!!
I am anxious to try this out!!!
I can only imagine the level of difficulty you may have encountered.

Awesome TIG!!!!!!

Crashed if Rail1 is clicked first

I think that's because the profile (now rail1) would need to be infinitely small where the two rails (profile+rail2) meet... I think it's trying to make tiny faces in the 'corner'... I know of this glitch and I am looking at ways of trapping it - it's not 'foolproof' yet !

Meanwhile use logically...

really beautiful, thank you so much.

i used it with the BZ toolbar, and you can set the segment amout for the line at the start which is a real time saver!

thank you again

Next will be Coon'Surface?
(just add the oposite profile as Rail 3

Pilou !
One step at a time...

Pilou, you want SketchUp to become MoI. Each one has its own.

Now there are distant cousins

If you take the previus 3 curves without connection between them you will obtain these flying fishes

Looks like it has a lot of potential, I have not had time to try it yet.
I was wondering if you had included, "Triangulate" or "Quad" face options?

cheers!

Seems we must have possibility to reverse rails before apply the plug!

I am looking how to fix this within the script - to fix it manually for now use scale -1 on the profile about the profile's centre...

The curious thing is that the Rail2 is a "straight line"
So must be divided , then welded
But result seems no reproductible and gives some nusty result

PS A multi-profils along Rail1 rail2 will be sweet too

Pilou:
I had similar results with the construction points on several attempts. Once, with rails made by Freehand tool and once with profile and rails made by Welded segments for profile and rails and once by smoothing out the profile with added arcs and Welding.
Since TIG said the script was mostly stable, I figured that there would be some of this to happen.

Can you all give as much info about the failures as possible [PM me small skps if appropriate] Ruby Console messages etc - I want to debug this glitch

[mitcorb]

TIG:
Thanks for the Example skp.
I will try to provide you with examples as time permits. And I have been observing the Ruby console.
My last experiment was with Polyline Divider as the profile and rails from Fredo's Bezier collection. I got the mesh ok, but of course, the math complexity reversed and crisscrossed the beginning and ending copies of the profile causing an oblate spheroid bulge(same shape as an American football) and wings like Pilou's harlequin flying fish. However, there was no comment in the console.
Unfortunately the file is saved on my home machine. I will have to send it later.
