@JRoach
I can figure the pain it would be to renumber this manually, so here is a proposal:
In short, I create solids from walls location lines (because it’s the easiest in my case, but any boundary lines would work as well) which I use to group the columns and to create a logical numbering sequence.
Group Curves is from Archi-lab Grimshaw and ObjectList.GroupByContainer is from Ampersand.
If a logical sequence is needed inside each boundary, I would probably take a look at Element.SortByCentroid from Chynamo for that.
Hope everything is clear enough…
Edit: to make it easier for others to find answers through the search field, could you pls reformulate the title of this thread (such as: Pile renumbering - need spline assistance)?
