STRUCTURE & SITE

Split by Level.

Split columns, walls and beams that span several storeys at the level planes: doors, windows and profiles are preserved, gap offsets are configurable, and sloped elements are handled.

01 · THE PROBLEM

Columns, walls and beams often get modeled spanning several storeys straight off — fast to build, but once the project needs quantities per floor, worksets per floor, or a construction-phase breakdown, each element has to be split back apart exactly at the level plane, without breaking the doors and windows already hosted in the wall.

Splitting every element at every floor by hand

Split Element can cut columns and walls, but only if you click the exact point at each level's elevation on each element — a building with dozens of storeys and hundreds of spanning columns and walls means repeating that click hundreds of times.

cửa/cửa sổ

A misplaced cut breaks doors and windows hosted in the wall

If a hand-picked split point lands too close to a hosted door or window, Revit can cut straight through the opening or orphan the family from its host — the mistake only shows up later, in a 3D view or a door schedule.

cấu kiện nghiêng

Sloped columns and beams don't cut cleanly with the native Split

Split Element draws its cut plane perpendicular to the active view, not along the element's own sloped axis — for a raked column or beam the cut lands skewed and has to be corrected by hand each time, leaving room for geometry mistakes.

0 gap offset

No option to leave a gap between the split pieces

Expansion-joint or fireproofing details between two split segments call for a small gap at the cut — the native Split tool has no such parameter, so each segment has to be nudged apart manually afterward.

02 · FEATURES

What it does

Column Splitter on the App Store (free, Revit 2023–2026) only splits vertical columns — by point, level or reference plane, and the listing itself notes it supports vertical columns only. Walls and beams are left to the native Split tool, clicked by eye. Split by Level handles all three element types at once, right at the level plane:

Select elements

Pick manually or auto-scan the model for spanning elements
Preview the cut positions per element

Cut at the levels

Cuts vertically at level elevations, not along a plan line
Doors, windows and wall profiles survive the split
Configurable gap offset between the pieces
Handles sloped columns and beams
Keeps the original tags — re-hosted onto the new elements instead of being lost
Asks for confirmation before touching elements that carry rebar
Does not clone the Mark onto every piece — no duplicate-Mark warnings
