Any chance you could post your custom Baluster file for me to take a look?  Only thing I can think is that it's something wrong with the way your baluster family is set up.

Also, if you can post a screen shot of what it looks like in 3D on your ramp, that would be helpful as well.

You should be able to edit your original entry and add the attachments using the attachments tab.

Let me know if you have any questions.

Hi again, attached is a project file with a stair and the angled balusters.  You should be able to extract the baluster family and use it and/or look at it to start your own.

Looking back on this, I was in a hurry when I made this.  As I previously mentioned, the better method of making this family would probably be to nest a generic model family into the file, and constrain it to a reference plane that you can control the angle of separately from the angle of the stair/ramp/host object (which is how I constrained mine).

You'll notice in my example that I also tried to create a mesh look, which wasn't too successful honestly.  I actually ended up just using a model fill region for this in my stair section.  The end conditions are also tricky as I previously mentioned, as you really have to create a custom start and end post.

I would be happy to try and answer any other questions you have, so please don't hesitate to ask.
