I am working with point cloud data to model a utility room. I have a railing for a catwalk that has irregular balusters. The first baluster is set at the right location but I cannot figure out how to adjust spacing for the remaining ones. Any help would be great. Thanks.
You might need to create separate railings, and specify where the "break" in the baluster pattern should occur, to get the spacing you need.
I have also seen Curtainwalls (with custom mullion profiles created for the railing components) used for odd conditions such as this--the curtain grid positions can be moved and the "mullions" will fill in over them--
Also take a look here:

Edit: It may also be possible to create a single "custom baluster panel" which contains nested generic model families that represent to unevenly spaced
posts/pipes in the existing railing.
