extrusion of a vertical profile

[fedekikko89]

Good evening, this is the first time I write in this forum.
use autocad for a while but only now I'm trying in 3d
My problem is:
I would like to make a 3d surface with some particular features:
1)must be extruded from a vertical profile;
2)Extrusion must have a 3d polylinea as trajectory;
3)what more important the profile must always be verticare and must rotate only maintaining orthogonal to the planimetry direction of polylinea 3d;
4)obviously follow the height of polylinea 3d.

the concrete example is:
I have a road in autocad that goes down curve salt etc..
the 3d polylines in question only the outer edges of the carriage
the profile to be extruded is nothing but a guard-rail.

the fact is that with the autocad controls (sweeps, extrudes) I can extrude the profile but, in the curved and sloped sections, the guard-rail does not remain vertical but tilts or towards the inside of the road or towards the outside.

I have been quite clear to ask myself
If you should have what alternative solution to the problem do not hesitate to suggest it..:smile:
help please.. (I need it for university)

thanks in advance

you could try with estrudi following trajectory.

Thanks for the answer.

I had already tried with extrusions following the trajectory.
the fact is that initially the profile starts vertically, then tilts slightly in the various directions trying to maintain orthogonal to the 3d polylinea that I used as a tractor.
and this is exactly what I want.. the tractor has to perform it always keeping in vertical position. .
Boh. I can't find any solution. .
Thank you.
other advice? :smile:

.....if you have which alternative solution to the problem do not hesitate to suggest it. . .

the only one that comes to mind is to insert the vertical profile in every 3dpoly summit (or at least every two or three, you have to do tests) transverse to the same, build a spline on the 3dpoly, and finally loft selecting in sequence the vertical profiles and tractor option (the spline).

depends on how long your way is.. .

thanks this works.:smile:

only that it is not as a method.. and then, as you probably already thought, the size of my road is considerable and this work should be repeated several times (even for more objects).
I'm looking on the internet but I still haven't found a specific command.
It's weird because the operation I want to do is not that complicated. .

I still wait for more answers. . .

but there is no automatic method to make railings, handrails or things like that?
because the problem is similar and maybe someone already knows the quickest solution

Thanks again
