Railing tool Pattern Setting doesn't match with Baluster Setting

[RafaelPretti]

Hi all,

I'm trying to model a timber paling fence using the railing tool and despite multiple attempts I'm not able to match the baluster and the segment patterns.
The balusters are made of 20X150 mm "palings" with a 10mm spacing between them.
The inner posts as set to max length of 2400mm which in turn is the segment patterns max length or fixed pattern length.
The paling should cover the posts and inner post but because there is a mismatch between the baluster pattern (that place the paling on the center node) and the segment pattern they neve match with each other.
Any ideas on how to achieve this?
Thank you

My guess would be that your interval spacing between your posts varies, meaning that your post offsets will need to vary between segments or your baluster spacing will need to vary. Your best bet would be to set your offsets to work with the majory of your segements, then use Edit Mode to modify the offsets of the ones that did not work.

So if I understand you correctly, you want something like this, where the balusters run in front of the inner posts and are equally distributed over the whole fence?

Okay, we need some math:

So e.g. if your baluster is 10 cm wide, and the gap is 1 cm, and you want 9 of them until the next inner post comes, then the segment length and inner post distance must be set to 9*11=99cm. With an odd number of balusters you need the method I checked in the picture, if its an equal number, the other "center" one.

Actually not that hard but I agree not very discoverable. Once you know you know.

HI @runxel 
I tried the same approach as you did and although it works well when the distance between inner posts are at the maximum, as soon as the distance is smaller or there is a "corner" there are gaps on the model.
Any idea how to fix this? I tried so many different ways but wasn't able to get to a perfect result.
I modelled exactly the same fence as you did, and those same gaps are still there (images attached).
Thank you

HI @Lingwisyer thank you for the tip, I tried that approach as well, the issue is I need the model to be accurate for scheduling purposes (no. of inner posts, no. baluster, etc) for proper quoting.

The thing is that you get to points like your corner, then you are adding a narrower custom panel, or are you slighting changing your spacing?

With fixed lengths, you will always get gaps unless those length are an multiple of the baluster+spacing width.

Try setting the balusters to 'Equally distribute' and set the max length to the baluster width + the maximum spacing you want - in your case 160mm.

You can also set the segments to 'Equally distribute' as well and you won't get segments with different baluster spacing because of the different segment lengths.

Hi Barry,

I had tried this approach as well with equal distribution on both segment and baluster settings.
Although it seem to be the best one so far it still has some issue whenever the length is smaller then the "max. lenght".:
Please see below 2 screenshots, on of them you'll see that it works pretty well, even at the corner. But on the second one, with a lenght of 1420mm, it has those same gaps between balusters and posts (it almost seem like whenever there are no inner posts/segment on the object archicad has a hard time creating the model):

I'm adding additional nodes, its the same railing "object".
I did think about just adding an additional railing for every turn and just keep them as straight lines but if I have a smaller length (see my reply to Barry above) then the gaps seem to appear once again.

[Barry Kelly]

Try adjusting the end offsets.

Zero doesn't seem to work but something like -30 might be better.

You may need to edit just that particular segment rather than the whole railing, and you may need to add nodes to break it into smaller segments.

Seems that there is an allowance for a post space even when there is no post?

I can't figure that one out.

Barry.
