Linear array corner woes (again)
« on: June 16, 2015, 10:30:29 AM »
I'm having difficulties getting this compound railclone object to behave. There are several issues, but first and foremost, the handrail and it's strange behaviour in corners.
Optimally I'd want the segment with the metal fittings to align with the outer vertical bars (even though they have a random transform).
My idea was that the handrail would have a fitting evenly each meter, and one on each side of a corner, with a segment in between
What have I done wrong?

Here is a file:

There's nothing technically wrong with the style but the corner issue is being caused by a limitation with using the Z Offset in adaptive mode. It can be fixed by adding a larger corner segment and adjusting the increasing Corner Bevel value but because it offsets on the X axis perpendicular to the spline it won't necessarily give you the path that you need for a handrail.

In light of this I think the easiest and most flexible way to get a handrail that follows the correct path is to clone the base spline and move it up the required distance on the Z axis. You can change the spline material ID to 2 and then Limit the handrail spline so that it uses only this spline. In this way you can complete control over the path of the handrail and the corner problems are eliminated.

Please take a look at the attached file for an example.

I hope that helps, please let me know if you have further questions.

Many thanks,
