Diferent Height boxes along spline

Hello..

I'm trying to draw a small pedestrian bridge, and I wanted to add different boxes along a spline has a hand-rail (a series of different boxes), in where I can control the measures... Then at the end I wanted also to add a spline, from which I control the height.

The big problem, comes along, when I parametrize for the height.

If I use a number slider it works fine...
But if I use a spline, it doesn't work.. the height goes uncontrollable

Any Idea?? How I can fix this?

Thank you for the help

Hei Matias,

Did you try something like this? notice that the curve from which you are extracting the z values (from the division points) should not have a height of 0 - this will result in no boxes, or actually boxes with height 0 = flat boxes.

Wow..what is that!??! :)

What are the definitions in there??

Can you pass me the files?

THANK You for your kind help :)

Thank you.. I got it now...
it was a point de-compound a pComP :)

Thank you.. it makes... sense.. but I wasn't getting there.. how to...
Because in my logic, I thought, that, the height should automaticly be defined the the height between the 2 curves...

THANK YOU once more :)

It seems very similar to piping, but with a retangular profile. I was asking myself if we are able to pipe specifying the section we want. I did that with a sweep, but I had the job to specify the plan of the section, that should be in the beginning of the rail...

Any idea?

Well Hugo,

If I understood right, you mean to specify the radius of a cylinder?
Means, different cylinders along the spline?
And then to know the correct section/radius?

Sorry, I didnt explained it coorectly.
These box looks like a pipe with rectangular section. (2 divided splines > create lines connecting the points > pipe it).

But, with pipe button we can make just circular sections. Wich comand we can use to makeother sections we need? Rail/Sweep?

I was more clear now?
