Thanks, Edson.

But I'm afraid no such long text could fit into that small space in the SU text field.
I1ll see though.

Since I had no idea that there was any character limit in SU, I just cut and pasted the additional comments instructions into this tutorial, updated the scenes and, viola!

Thanks for all your great tutorials,

Oh, Eugene, thanks for all this. I just totally forgot about this whole trhing...

as for the text length, it was partly a joke and also I just meant that the text is so long that it won't really fit on screen (I guess)

[majid]

recently I saw this..... verrry useful and simple, but not accurate enough ( as the arc must be helix-ed shape when see from side, but it remains arc again)
thanx again Gai

Hi guys,

Dear Gaieus,
It is always a pleasure to follow your tuts. (thank you to give a SU6 skp )
As an exercise I had tried to find another solution:

Here is my alternate way:(SU6 skp)

Using:
Fredo's Curviloft and Joint PushPull

Thanks guys...

Majid; maybe not accurate but back in 2007, there were not so many excellent plugins to skin a helix very easily...

Simon: this is also the reason why it is still v. 6 - version 7 came out later (I think).

I hadn't noticed the date

[Gaieus]

by the way, Simon, why don't you upgrade to 8?

[simon le bon]

I have SU6 free and SU7 Pro on my big PC and SU8 free on my laptop...

SU6 Is ok for everything I do; have never used dynamic component and I prefer the behavior of SU6 PushPull tool.
I have bought for long Whaat's BoolTools, and actually nothing in SU8 free grab me more: I'm very sorry for that.

Okay but now as the shadow bug is gone in SU 8, image export is possible at a much higher resolution etc., maybe it would still be useful.

Not to speak about some new generation plugins that may not work in earlier versions.

Sure I still have both version 6 and 7 installed, too.

[simon le bon]

And Ho!
I was forgetting the ability to record our toolbars position in 8: what had always put a lot of people and also me very out of serenity with the previous versions.

for sure your tut is veeeerrry handy and easy to follow
@ simon : thanx , but the non-accuracy exists here again

Can you explain a bit more I'm not sure to understand completely what is the problem.

[majid]

dear Simon
I've attached a file that shows a real pont to point modeled rapm, and a tricky fast way ramp on(Gai trick) that clearly shows the difference.

Dear Majid,

Your "point to point modeling" is perfect to draw a real helix!
But in our specific case, as we need the curves to be tangent to the horizontal planes this pure helix doesn't work very well. Am I once again missing something?

Cheers,
Simon.

The best result I achieved with the Arc tool and followme and keep. The arc was divided to 48 sectors. The end of the ramp is then still not tangential but the transition to the horizontal is optimized.

thanks charly.it's ok.

[mitcorb]

"Slant Ramp Tut" that's bound to offend somebody somewhere, sometime. Perhaps on Tralfamadore?

[simon le bon]

Thank you Charly!
->applying your solution with FollowMeAndKeep .



How have you made the path?
Here I have applied my first solution:the 48s arc and two edges drawn on the ground, then the left edge selected and moved up!
This seems to me to be good but! may be Majid will object something. There is something in the problem I don't understand.

Simon.

[majid]

my only objection is : by moving up/dn and scaling an arc, we will not reach a helix, while mimicing it, BTW if we need a ramp that is tangented to horizon start, it is a fast way.
(also I am aware of draw helix, and FaK plug) .apart from them and using native SU, there are only 2 ways in my sight, point to point , and tricky Gai way.

[Gaieus]

Yeah, back then there was no Follow me and keep so one would either use helix.rb (which existed) and painstakingly connect the endpoints or do some trick to mimic something in a faster way.

I ma glad though that I started to learn SU back when there were not so many, excellent plugins as nowadays. It forced me to find out workarounds and if nothing helped, there was always "had stitching". I think this approach would still be useful for many newbies before they rely themselves to the easiest methods with plugins.
