I'd recommend an extrude+intersect combo selected simple and effective.

P.S. Joe Pecshi sucks comparing to this nugget!

чем он отличается от уже сушествуюшего?

@sahi
MGIMO finished?

You need a better lens\camera. Good pics but too blurred

top=0
base=-100
Isn't it supposed to be sloped?

0-100.skp

The huge time saver! So far only 2 minor bugs: Only context menu item starts procedure, no reaction from menu-plugins-curve shearing. The Base ramp negative value
(with "-") generates simple offset- no ramp shape.

It's ok now. just firefox glitch. Gone testing and thank you!
Sometimes I think the SU dev team is fooling community playing behind Fredo pseudonym.

Astonishing gif! But what's wrong with attachment?

There's outline of the ramp (plan). Say by design the end (AB) should be at -400. Please make the model of the ramp using FDD or Smoove tool(don't forget about clean interpolation). And good luck!
@Fredo: I swear you was the real target of the topic starter! Gotcha!

ramp2.skp

This is close to what I want in SU:

2 main things: interpolation and no plan screwing.
P.S. Even more:

You could skip the russian intro and gostraight to ~2.00

TOS has currently a problem on closed surfaces.
Try to remove the bottom of the cylinder and it should work.

Fredo

Yeah no worries I've found workaround. And thank you for the TOS once more!

Hi mates! As I can see the disscussion went in the wrong direction (mea culpa).
I have no problem to build this damn ramp and the things like that (with at least 2 difftent ways:
1.extrude plan outline->surface tools->loft (more correct)
2.followmeandkeep.rb->interset with extruded plan (less correct))
Both ways take time and efforts. The aim of this thread was to catch some ruby maker's eye to
the neat (IMHO) idea- to move curve's vertexes in a kinda 'interpolation mode' and without plan distortion, or maybe to find
the already existing script.
Sorry for the lack of clarity

Take a look at this skp file. Hope it'd explain the problematics better then my broken english does.

ramp.skp

Take the arc's end and drag it upward. Take a look at the twisted result in the top view. Zorro.rb is a totally diffrent story- the cylinder in the example picture is just a visual aid.

I would use ...zorro!

for Seppuku?

Just thinking aloud.. The original SU product placement is urban design\architecture. Historically
the plan (plan view) is the 'alpha and omega' of the design process. I really can't see any benefit\use in curve bulbing. It appears there's a good niche for some ruby geek- the 'Interpolated_vertex_move.rb'.. or something like that

Try exploding the arc (right click on it an dchoose explode arc) before moving its vertices. That might help,

Chris

The blue one is the explode+weld inheritor.

There's some strange feature (personally I'd call it a bug)- moving the arc\curve endpoint in Z direction distorts the plan view (alters the radius value).
Is some some tool or ruby that would make the curves keep original plan view.
On the picture:
1 The Original geometry- red AB arc
2 Movin B to B1 causes blue\green pregnancy (depends on arc\curve)
3 The Yellow one is what really I need.
Thank you in advance
