Creating a custom specific railing

[KecoLo_Design]

Hello! I am working on an existing aera in a University building. There is an accessibility ramp and a few stairs with a metal handrail (see photo).

As this component will not be changed, I have to draw it as accurately as possible. What would be the best way to create that type of "tube railing" with rounded corner?

I know how to round/curve a corner of a 2D figure but I don't know how to achieve this with a solid cylindar shape. Anyone can help with this or direct me to a tutotial if it exists ? (I did look, but couldn't find what I'm looking for). 

Many thanks!!

With any stair or ramp, in their DBX 

• Choose Railing, then Style "OPEN", Include Top/Bottom & raise/Lower bottom = 2'
• Choose Newel/Balusters, then Type=ROUND, 2" width.
• Choose Rails, then replace both top rail & bottom rail with "Tubing Round" 2"
•  Choose Materials, then replace newels & rails w/ BLACK (or another material of your choice.)
• This will give you the railing style you are looking for.
• 

For the handicap rails ends, it is a bit more fun.  In 2D draw a moulding line extending from one end of a staircase.  I changed my line weights to 1 to make things easier to see.  Change Molding to "Tubular Metal" 2".  Note, because I was lining up with the ramp snap point, I had to offset my molding -3/8" to get the tube to line up with the stair/ramp tubing.

 

Open a cross section camera looking at the rail section.  Raise the rail from the floor on which it has been drawn to match your rail height.

Then highlight the molding and extend it around in a loop return.

 

In 2D view mirror your railing so that it is 3/8" offset to match your initial.

 

Switch to 3D view and paint it black to match rails.

 

Select both moldings and mirror to other side of ramp/stair.  Then in 2D view raise/lower moldings to match height of that side of the railings.

Voila!  

 

If you zoom in close, the bottom rail has a better welded look than the top rail which is riding slightly above the rail.  I couldn't figure out how to automatically fix that short of connecting the rail end pieces and making my own horizontal rail, using only the stair posts, no railings..

WOW!  I am amazed!! Thank you so much for this very detailed instructions. I will try my best to come up with a result as nice as yours!
