Structural Column Location

Packages

kulkul-

I’m with Timon on this - what you showed only will work if the columns are slanted column. It is possible to change the columns to slanted, pull the locations and/or curves, then switch back to vertical columns, but that taxes the system pretty good if you have more than a handful of columns (note the conversation in the post Einar referenced)

Timon-

Try this bit of Python Script (it’s essentially a modification of element .location + the top and bottom offset calculations)
