Railing - managing length and joining with terminations

[maciej.rudecki]

Hi,

is there a possibility to control the way the railing joins with the terminations? As you can see on the picture below, it doesn't connect automatically and I cannot find any setting that controls it. (The railing is sloped since it is hosted to stairs.)

Secondly, I'd like to shorten the lower part of the railing (T profile) a bit but the "Length" parameter is greyed out - maybe there's some way to unlock it? 

The upper part of the whole railing consists of: the "handrail" with "terminations" (round profile) and the "top rail" (T profile)

Thanks in advance!

For the termination and the way it connects to the rail, you need to edit the termination family and model the transition/connection therein...you can find them in the project browser >> families >> under category Railing

.

For the length ...Edit the sketch of the rail first to shorten a notch finish sketch then  tab select the top Rail >> edit the Profile >>> extend it slightly

You cannot shorten a top rail without an extension.  In other words, the top rail (and handrail) sketch cannot be shorter then the railing sketch. 

If the railing is not on a slope, you can draw the railing sketch the same length as the T length, offset the start and end post outward, and add extensions to the round handrail to compensate the length difference.

For simplicity, you can create the T as a separate railing type, and sketch it shorter in the same place as the main railing.  That would work for both flat and slope conditions.

The upper part of the whole railing consists of: the "handrail" with "terminations" (round profile) and the "top rail" (T profile)

Thanks in advance!

Extended without the termination by editing path as mentioned above ... Alternatively you reset the path and extend using a custom termination family

Not clear what you want, but I'm wondering if you can get there with an "Extension Style" and "Length" (under the Type Properties for the Top Rail).

I cannot find the "transition/connection" option in the termination family in edit mode. Could you please explain to me where this option is located?

@maciej.rudecki 

It is not an option ... you have to use a family template or edit an existing one and model it therein...ie: you create a custom termination family using extrusions, sweeps, blends...etc that follows the slope/angle of the rail from one end and extends further in which ever direction you wish or shape you desire

If it is a simple thing similar to the image I posted above, then you do not need a termination...you can achieve that by editing the Top Rail path

How about you sketch how you would like the end product look like?

[maciej.rudecki]

Thank you for the response.
According to what you wrote, I assume there is no possibility of creating the railing the way I want it to be using just one railing family.

I will try then to model it using separate families or maybe create a new railing family, but I need it to be adaptive and usable as the built-in one, so it won't be easy.

After all, the point is to schedule those railings with all the needed dimensions and quantities (railing length, height, number of ballusters etc.) so I think the easiest way is to create two railings and assign the same parameter value in order to schedule them as one.

Below you can see a photograph of the railing - maybe you'll come to some other solution.

Thx

Ok, I created the termination just as you described it.
I can see that it connects well with the horizontally aligned handrail but doesn't work with the sloped one.
The railing itself is very simple, I didn't expect it to be so problematic to model it.
You can find the photo of the railing in the post above.
Cheers

You need to edit the Top Rail Path and give it a nudge forward (you can reduce the Termination thickness to deduct the added height

[maciej.rudecki]

Wow, I didn't know about this trick. Thank you very much!
Now I am proceeding to counting balusters... I think this will be the case for another topic :pp

Again, thank you!

I have recently stumbled on these sites that provide Affordable and Professional Railings and Custom Iron Work. The guides are super easy to follow and I actually enjoyed their services. You can also check the website yourself: https://www.abbcorailing.comhttps:

When I tried this it still cuts the custom extension perpendicular to the ground. I'm stumped what is causing this.
