Baluster top angled

drenL5229 — Wed, 07 Feb 2024 19:08:32 GMT

Hi all,

I have posted about this previously but didn't have any luck in resolving it. Basically I want to achieve an angle at the top of the baluster which is perpendicular to the angle at the bottom which follows the slope.

So the railing will be at a slight slope where the base follows the slope (this is working) but I want the top of the baluster to be cut as per the wooden cap that will be used for leaning/lookout.

Please see attached a snip of what I am trying to achieve.

Thank you for your time and effort!

You need a parametrically-controlled, angled Ref. Line in the family to constrain the top of your Baluster geometry or constrains a Void that cuts the Baluster at an angle.

Post your Family here.

....you're also going to need angled Top Rail -- if I'm understanding the design intent correctly. Can you post a photograph of the actual railing?

So the top rail slopes away from the stair? It can be done with two voids, one matching the stair / ramp slope, and another slope in the perpendicular direction. Share the family here.

@barthbradley ,

I was trying to achieve that and thought of using reference lines. But yeah the void would have to be aligned to that angled ref. plane or line.

You can see below the railing it is still in progress of course.

I will try to reply shortly when I get a chance to try the void thing.

I thought this is what you were describing. No?

@barthbradley ,

Yes the only other thing would be that the balusters themselves would have a plate that follows the slope. But that I could get to work since it is relatively easy.

Can you please let me know how you achieved that. I have created parameters to control the top void angle but they are not working in the project.

Thank you!

@barthbradley ,

Please see attached the section of the railing family inside the project.

There is a gap, between the baluster and the top rail element.

It would be done as I said above in Front or Back View.

Post your Baluster family.

Okay? So, what are you telling me?

I get it now. I know why there's a gap. Post the File.

@barthbradley ,

Here you go, thank you!

Also, @barthbradley , just in case we don't need any angle can we make it that way that we can control it through visibility parameter on/off so that the void is present only at angles >0? I know it is possible but I am not sure how to set it up.

EDIT: managed to get the on/off void thing to work.

Does this help? I did this in 2024. Could you open it if I posted it?

Regarding Sloping Top Rail, that's created via the Profile. Pay attention to the Origin.

I don't have the 24 installed on this current PC but I have at home so you can post it and I will open it later.

I appreciate it.

@barthbradley ,

Managed to make it work by locking reference lines to the reference plane of the top cut angle so that the void always follows the top cut angle (90 degree angles between reference line and plane). The angle of the void itself is controlled by another parameter and also if there is no angle it will not be on (the void). Used 3 reference lines so that if needed I can control the length of the extrusion of the void but I don't think it is necessary.

Attached some snips below so that it is more easy to understand.

Yah, that's critical. You have to lock the tip of Ref. Line to both x and y intersecting Ref. Planes.
