Ahmed,

I would create a custom railing using columns for the posts and walls or beams for the hand rail. Place the columns as you wish along the sides of the sloped ramp and use the gravity tool (see attached) so that each column will fall to the surface of the ramp. Gravity tool will only work on slabs, roofs and meshes though, so your bridge will need to be created with one of these tools for this method to work.

Then using the elevation, as a reference of what you have created so far, create a profile for the hand rail that will sit atop the posts. I would use the wall tool as it will heal better where the curvature of the rail is more intense.

Here is a great article by LaszloNagy on the ArchiCAD Wiki that explains how to use a beam or the curved ramp tool to make a curved beam (in this case, a spiral): http://www.archicadwiki.com/SpiralBeam.

Ahmed,

Or if the slope is no too great as I have just noticed in your picture you could use the gravity feature to place the railing on the slope and then adjust the inclination angle in the object settings under Parameters>General Dimensions>Inclination Angle.

You will need to adjust the inclination angle because the gravitate feature will not put the object on the angle of the slope below, it will only place the insertion point against the surface of the slope and leave the rest of the object horizontal. So initially you may have one end on the slope as desired and the rest jutting out in to space or into the slope itself until you adjust the inclination angle.

Ahmed,

Always happy to help. Helping you helps me to learn as well.

By the way if you ever come to Utah for skiing, hiking or the Sundance Film Festival, make sure to let me know so you can buy me lunch. 😉
