Custom Ramp Rail (Concrete Parapet & Beam)

[IAN~JAMES]

Hi

I am creating a Revit model of a multistory carpark and I am trying to get my head around the Ramps at the moment. There are a number of complex issues that I need to resolve, but initially I seem to be only able to get a pedestrian looking ramp with a handrail. What I want to do is to replace the handrail with a concrete parapet wall and possibly an integral downstand beam like this:-

I have tried creating this as a family using the "Metric Profile" and the "Metric Profile-Rail" templates and I have managed to create a family member, but I am not sure it this works, because I cannot select them in the ramp tool as they appear in the Rail options for the ramp.

I am wondering if I am totally on the wrong track. My Ramp is made up of a radius top and bottom section with a straight in between thus:-

I do need to consider variations in the gradient at top and bottom for transition ramps, but I will be happy just to get this bit working to start with.

The point here is that I need the parapet/beam profile to follow the ramp boundary lines in the same way that a railing/barllustrade does.

Can anyone put me on the right path please...? I think the salient questions are:-

What is the right Family Template to start with?

Can I make a non-rail family type become a rail family type so that it can be associated with the Ramp?

Should I be approaching this totally differently?

Thanks in advance and Merry Christmas

Cheers

Since it is important that the section of the beam remains correct along the path, I suggest this solution:

Component > Model in place > Swept Blend > (create Profile 1, Profile 2, and pick the path from the ramp)

This would have to be done segment by segment, along the ramp.

There is a way to select multiple edges, using Sweep. but the profile of the beam twists itself inwards, creating inaccuracies.  This segment-by-segment swept blend takes more steps, but the section of the beam is always correct.

See illustration.

There is a better solution, using a railing profile, posted by Martijn de Riet, at this link:

dear all,

i m having problem to indicate the ramp line in the plan, normally we use the revit for 2nd and 3d drawings, in 2d drawing we need to show the ramp lines, i had try to do using revit hatch but couldnt make it, anybody can help me in this?

thanks
