Slab & Beam Splitter.

Split slabs and beams along a line: pick lines, two clicks, grid lines or freehand — a solid-boolean algorithm turns N lines into N+1 pieces in one pass.

01 · THE PROBLEM

Revit's native Split tool runs on walls, beams and pipes — floors get no Split command at all. To break a large slab into separate concrete-pour zones, engineers fall back on Split Face (which only changes the display, not the element) or redraw a brand-new Floor sketch for every piece, and each redraw wipes out the structural parameters that were already assigned.

Floors have no Split tool at all

Revit's Split Element command only accepts wall, beam and pipe categories — Floor is not on the list. The only fallback, Split Face, just divides the visible surface; it never produces two independent elements.

Splitting a beam across several grids means clicking every point by hand

Split Element does cut beams, but only one point per pass. A beam crossing eight or ten grid lines means repeating the click that many times, with no way to preview all the resulting pieces before committing.

Redrawing the sketch drops the structural parameters

The only way to truly split a slab is to sketch a brand-new Floor for each piece — Revit doesn't carry over the structural usage, phase or project parameters from the source slab, so every piece has to be re-tagged by hand.

No way to see the result before the cut lands

Only after the sketch or Split Face is finished do you find out whether the resulting shape is right. Get it wrong and the whole chain — draw the boundary, reassign parameters, check it — has to be undone and redone.

What it does

On the Autodesk App Store, Divide Floor (BIM Studio, free, Revit 2018–2022) only handles floors — it re-splits joined floor geometry back apart, and the process wipes every parameter the source slab had. Revit itself is narrower still: Split only runs on walls, beams and pipes, with floors left out entirely. Slab & Beam Splitter covers both element types in one window, and keeps the type and parameters intact after the cut:

A

Choose the cut

  • Four ways: pick lines, two clicks, grid lines, draw a line
  • Several cut lines in one run
  • Preview the resulting pieces before executing
B

Split

  • A Dynamo-style solid-boolean algorithm — N lines become N+1 pieces
  • Keeps the source element's type and parameters
  • Extends the cut line to span the whole scope — a short line still cuts
  • Re-hosts tags onto the new pieces instead of dropping the annotation
  • Asks for confirmation before splitting beams that carry rebar
  • Undo stays enabled only while it can safely revert that exact split
  • Pairs with Merge Beam/Slab to reverse the operation
